Hydrogen

Is the UK Hydrogen (H2) Ready?

Is hydrogen the future? Is the UK Hydrogen (H2) ready? Hydrogen has long been thought as the clean alternative to natural gas. Which could soon be used to power the appliances in our homes. To include not only boilers, but hob, cookers and fires too.

The first UK houses have been built and are set to be fuelled entirely by Hydrogen. The houses are due to be open to the public to learn more about the emerging technologies. Finding alternatives to fossil fuels and a move towards making clean energy the norm. Thus giving people a glimpse in to what the future might look like.

Hydrogen burns cleanly, producing only water as combustion. Making it ideal as a net-zero economy fuel. Hydrogen also has the benefit that it could be distributed across the country using the existing mains gas infrastructure.

The government is hoping hydrogen, as a clean and safe replacement to natural gas, will play a vital role in achieving its commitment of the UK’s contribution to climate change by 2050. By implementing their Ten Point Plan.

The Hydrogen Strategy is to be shared later in 2021, to show that the UK is indeed Hydrogen (H2) ready.

The technology is already here with the New Viessmann Vitodens 100-W & 111-W, which are now available!

Boiler servicing Winchester

Boiler Servicing – An Essential Investment

A study has found that watching spending has become an ingrained way of life that consumers will continue with, even when their finances improve.  It seems the recession has left behind a legacy of cautious consumers, with people needing a strong reason to part with their money.

VITAL BENEFITS

An annual boiler service, however, needs to be seen as essential spending.  In much the same way as a homeowner would regards a service and MOT for their car.  Most people anticipate there will be ongoing costs associated with their vehicles and budget for them accordingly.

An annual boiler service provides some important benefits; it will ensure the boiler is safe, is performing efficiently and reliably, and maintains the manufacturer’s warranty.

SAFETY

The number one reason for a homeowner to have their gas boiler serviced regularly is safety.

Unfortunately, consumer awareness of carbon monoxide (CO) poisoning is thought to be generally low across the UK.  It is important for heating engineers to explain to their customers that unsafe gas appliances – those that have been incorrectly fitted, badly repaired or poorly maintained – can produce this highly poisonous gas.

According to the Department of Health, 50 people die each year from CO poisoning and another 4,000 are treated in hospital.  It is thought the true number is likely to be much higher, as the early symptoms can easily be mistaken for flu or tiredness.

LONGEVITY

Another benefit of regular servicing extends the service life of your heating system and ensures reliable, trouble-free operation.  This is the only way to make sure that the energy from the fuel is used efficiently and cleanly, thus protecting the environment and saving on heating bills and the likelihood of breakdown, saving the homeowner money and minimising disruption without compromising high heating and hot water convenience.

Again, it is useful to draw on a car analogy.  A homeowner will understand that things like replacing filters and spark plugs are essential to keep their vehicle in top condition, and that avoiding a scheduled service may have a detrimental effect on the way the car works, leaving them out of pocket in the long run.  The same rules apply here, the boiler, burner and control unit form a system like that of a car engine which is essentially runs for many more hours than a car.  If your car was in operation for the same amount of time as your boiler, it would cover more than 60,000 miles in a year.  All car owners know that they need to have a service carried out at regular intervals.  Therefore your heating system should be serviced at least once a year, much like your car.

WARRANTIES

An annual service is usually a condition of a boiler warranty – which is another important reason why you as the homeowner should invest.  Today, boilers come with lengthy warranties, which should be seen as a sign of reliability, but the working parts still need to be checked annually.

AHS Team at Escape Rooms

Celebrating 20 Years at AHS Continues in Winchester

We all shout … HELP ! … and out of nowhere a Siri like voice offers cryptic guidance.

No, the team are not at a séance but actually the escape rooms for the 20th Anniversary of Alexandra Heating Services.

Alexandra Heating Services thought 20 years of successfully serving our customers was well worth celebrating. So after lunch at The Stable in Winchester we arrived at the escape rooms on the Broadway, to put our collective minds together.  In hope of figuring out the cunning puzzles and conundrum’s set before us. We had split into 3 teams, with each team entering a separate “room” from which they had to escape. The aethereal voice was each rooms controller, watching via video. While no doubt enjoying the ensuing debates about the meaning of many clues and props. Everyone had a great time and inevitably competitive traits emerged, each wanting to be crowned “top team”.

Afterwards we descended on a local hostelry to compare notes, game plans and talk about one teams secret weapon.  Turns out Carol in accounts is a puzzle queen! Everyone got changed and joined up for a local dinner, at Cote Brasserie, where the hours flew by and much banter was enjoyed by all. What a treat for us all!

As part of this celebration is an important THANK YOU to all our customers who have supported us over the years and without you there is no Alexandra Heating Services.

Here’s to another 20 years of service and support to our local area.

Celebrating 20 years of AHS

The year is 1999 and major events are taking place.

  • “Y2K” is looming and the associated prediction of IT systems failing and catastrophe (which as we now know was rather inaccurate).
  • The “euro” gets introduced to the worlds financial markets,
  • The Matrix film (the first of the trilogy) is released to huge financial success & critical acclaim.
  • …. and Alexandra Heating Services is launched.

OK, so maybe AHS is not quite headline news compared to the others but to us at AHS it was the start of something big.

20 years on and we have not only grown in both employees and premises.  But also we have broadened our horizons to new areas such as renewables. Along with creating an electrical division.  One thing hasn’t changed, ultimately the customer always comes first! The same attention to detail and professionalism is as important today as it always has been.

And as part of our celebrating 20 years we are delighted to offer new customers an introductory 20% off all servicing. Between 1st July and September 30th 2019. Please quote CELEB2019 when calling 01722 417873 or emailing us.

We look forward to serving the local area for a further 20 years, so if you have heating or electrical needs or want to talk to us about renewable energy we would love to hear from you.

Swimming Pool Boiler Install

AHS Saves the Wedding Day

The big day for a wedding in Stratford Tony, Salisbury was looming with much excitement and anticipation, so time for one more check through the list:

  • Invitations – Sent.
  • Catering – Ready.
  • House – Clean and tidy.
  • Lawn – Cut.
  • Gardening – Done . . . do we need more balloons and flowers?

But suddenly there’s a BIG problem.  No one had checked the swimming pool and it was COLD!

With only a few days before the wedding and guests looking forward to a refreshing swim in the pool, you can imagine the distress.  A quick call to Alexandra Heating Services, and shortly afterwards with an engineer visit, he had diagnosed the problem.  All options were considered, but the conclusion was the swimming pool boiler couldn’t be fixed. The bad news had to be delivered that the swimming pool boiler needed to be replaced.

The Techy bit:

Alexandra Heating Services has designed a swimming pool solution based on the award winning and which best buy Viessmann condensing boiler technology, coupled to a heat exchanger with titanium internals and a Poolsmart plus controller.  Designed to run more efficiently (Viessmann boilers can run up 98% efficiency) and with excellent durability and longevity (thanks to Viessmanns’ German engineering and the titanium rods within the pool heat exchanger).  Our customer decided to have the AHS solution installed over and above the normal contenders, such as Certikin.

After a concentrated effort by AHS, our heating engineers had the Viessmann swimming pool installation up and running.  With a day to spare before the ceremony.  The wedding went smoothly and even the sun shone – a happy ending all round.

Our delighted customer, based in Stratford Tony, Salisbury, Wiltshire, kindly sent us a picture of wedding guests enjoying the pool.

That was all 1 year ago (May 2018) and so we asked, have the benefits materialised?  To quote our lovely customer: “It is too early to tell if the running costs have reduced, but I’d be very surprised if they haven’t. The water certainly heats up a lot faster, which is a considerable advantage.”

If you interested in learning more about our swimming pool solution, please contact us.

Viessmann Boiler in a house in Winchester

A Day in the Life of Our Engineer

MY DAY BEGINS . . . 

It started earlier than usual, meeting our service engineer at the unit in Old Sarum at 7:30am to ensure we arrived at our first job on time at 8:00am.

Ready to start our day. . . .

AHS Ltd Van

JOB 1:

Our first port of call was a gas boiler service in Redlynch.  After informing the customer of our arrival, we accessed the boiler in the garage.  The engineer showed me how to safely remove the case of the Viessmann boiler to expose the inside.  He talked me through each of the components that make the boiler work and then using the Viessmann toolkit (pictured below):

Viessmann Toolkit

I was shown which parts needed to be removed in order to carry out the service.  This is a careful process which begins with, most importantly, switching off the gas supply to the boiler.  Once this is done, the burner needs to be removed in order to check the burner seal, electrodes and clean the heat exchanger as necessary.  There is certainly a knack to the removal of the burner, undoing clips in the right order, followed by the screws and then removing the unit safely ensuring not to burn yourself or damage the part itself.  Once this has been done, any wearing parts are then checked and changed if needed.  On this occasion, we replaced the burner seal, which is a rubber ring that the burner leans on when placed back into the heat exchanger that houses it.  Whilst the engineer did this, I used our dry vacuum followed by cleaning wipes to ensure there was no loose debris or dust inside the boiler.  Once the boiler was put back together, we fired it up and put it into service mode.  This allows the boiler to produce emissions as it would when in full demand and whilst it did this, we used the flue gas analyser to check the boiler was producing a safe gas reading.  Once the gas readings were taken, they were printed on site and attached to the CP12 certificate that the engineer had already began writing out.  This left me just enough time to finish my coffee and biscuits, before asking the customer to sign the CP12 and setting off to our next job.

JOB 2:

Our second job took us to an industrial warehouse building, much like our own for another gas boiler service on a Viessmann boiler.  This time our engineer carefully watched as I carried out the initial checks, such as turning off the gas supply and unplugging the burner controls, unscrewing and removing the burner.  I replaced the burner seal under the careful watch of our engineer.  After giving the boiler a good clean inside and out, and completing the CP12 we were ready to leave another happy customer with a newly serviced boiler and move on to our 3rd job of the day.

JOB 3:

Our next job took us out to one of the first Viessmann oil boilers installed by AHS Ltd.  On arrival, our customer wanted to tell us just how much of a difference he had noticed in the first year, by changing from his previous boiler to the energy saving Viessmann – always great to hear.  Once again, our engineer talked me through the components that make up a Viessmann oil boiler and what parts needed to be checked during an oil service.  I was impressed by the kit that accompanies these boilers that allows for an engineer to remove the main heat exchange, while being supported by a clip-in mechanism on the casing of the boiler.  This is helpful due to the size and weight of the heat exchange and means less wires need to be unplugged and put back in.  After checking all wearing parts, this time with no replacements needed and cleaning out the boiler, we completed the CD11 and had it signed off by the customer before leaving.

JOB 4:

Our final job of the day took us to Owslebury to look at a broken flush mechanism and leaking WC. Having read our jobsheet in advance, our engineer had an idea of what the issue might be and therefore how to resolve it. We therefore stopped off at our suppliers to pick up the materials and then headed on to the job.  Arriving to a houseful of wedding guests, meant we had limited time to cut off the water supply and rectify the leak.  Whilst our engineer dealt with this, I used our wet/dry vacuum to remove any water left in the cistern – ensuring to put down sheets to protect the customers floor from any water damage in the process. Once the water had been isolated and drained from the cistern, it was removed. We found the existing flush mechanism to be damaged and the doughnut washer was allowing water through. Whilst I constructed the new flush mechanism ready to be installed, our engineer replaced the doughnut. The replacement flush was then fitted, water switched back on and the WC tested 2 – 3 times checking it was in good working order and no leaks were apparent.  Another happy customer!

MY EXPERIENCE:

The drive back to Salisbury bought us to 5pm and the end of our shift. I thoroughly enjoyed my day out in the field and not just for all the biscuits!

Perks of being an engineer for the day

It was great to see a different aspect of my job and meet some of our customers. It was very nice to hear them praise the company’s previous work as well as their appreciation for the benefits of our installations.  From an office workers point of view, it was rewarding to know that our well planned routes are worthwhile and save travel time in the day for our engineers. Overall, spending the day working with an engineer was a fun and interesting experience.

Fighting Legionella

It is well understood that legionella, a bacillary germ similar to pneumonia, causes severe health issues for humans.  Recent cases of legionella infection have prompted industry figures, such as the Association of Plumbing and Heating Contractors, to speak out about the importance of quality materials and disease prevention training for those responsible for the control and maintenance of water systems.

The issue of prevention runs deep however, right back to the initial system design stage.  A fundamental part of good water network design is rooted in understanding how the choice of materials used can affect the health of a system.

A system which is correctly designed from the beginning will encourage the correct flow of water without creating areas where water is stationary, stagnant and susceptible to the risk of bacteria growth, and potentially legionella contamination.  ‘Dead Legs’ in a system, where a section of pipe contains unmoving water, are a major risk for legionella growth and eliminating these in the first place can go a long way to fighting waterborne diseases throughout the plumbing system.

The proliferation of bacteria such as legionella in water systems can pose a major health risk, particularly for vulnerable people such as the elderly.  Recognising the severity of this issue, EU regulations were introduced to provide a consistent water quality policy for all member states during 2015, with more to come.  The plumbing industry has a huge part to play in ensuring that quality control is maintained.

IMG_9576

THRIVING BACTERIA

Legionella-based illness are contracted from inhalation rather than ingestion; the bacteria thrives particularly in water circuits where the temperature ranges between 25 to 45 degrees Celsius and is most commonly transferred by aerosol action, such as water vapours from air conditioning systems and faucets.  The spread of this type of bacteria depends on certain key elements; the nature of the water, absence of circulation, ambient temperature, lack of on-going treatment, and sometimes the choice of materials used.  It is therefore vital that these main criteria are adhered to when trying to avoid contamination of the water systems.

HEALTH & SAFETY

According to the HSE – L8 approved code of practice and guidance document, the growth of legionella bacteria in pipework can also be linked to biofilms essentially nutriment build up), which are in turn linked to the survival of waterborne bacteria.  Good design and construction of a pipework network is key to optimum system functionally, yet the choice of materials used has also been found to substantially improve the health benefits too.  Studies gathered by International Copper Association regarding cooper’s ability to destroy a wide range of bacteria, including legionella, show that copper kills at least 99.9% of bacteria within two hours of exposure.

Control of Substances Hazardous to Health regulations impose a responsibility on persons controlling premises, or its water system, to ensure that all harmful bacteria is minimised.  Filtration and reducing the build-up of debris that can act as a nutriment source in water systems is an important step in minimising biofilm in the system.  However, while copper is proven to have antimicrobial qualities and ongoing mechanical benefits, it should not be installed as a device for sterilisation or as a means of improving the potability of the water system.

Choice of material aside, good maintenance practice is paramount and without it bacteria growth in pipes can increase.  Rigorous maintenance should be implemented to ensure all breakdowns in the network are minimised, which will in turn reduce the risk of bacterial growth developing in water that has sat in pipes for extended periods.  Once installation is complete, it is essential that those charged with maintenance understand how to completed checks and report any concerns.  If we take these points on board as an industry, we can minimise the proliferation of legionella bacteria and the threat of Legionnaires’ disease in our water heating systems.

OUTSTANDING SERVICE

Our water went from hot to tepid to cold just before the Easter weekend. Nightmare with 3 teenagers at home. The problem was not clear but AHS went the extra mile out of hours to find the problem. Once the problem was clear fixing it was also obvious that fixing it was not going to be easy. However a temporary fix meant we had hot water over Easter. THANK YOU ! It was clear a lot of thought and time had gone into finding a solution that would work with our existing system. This was installed with minimum fuss and maximum efficiency ( as usual) and a decompressor valve added to avoid a similar reoccurrence. AHS is an amazing company who really do go the extra mile. fantastic job. Thank you.

New boiler and tank

We have used AHS for many years now, so when our old cast iron stove finally expired, then they were the obvious choice for a new system. After much honest and professional discussion, a new system was agreed upon for our heating and hot water.

The installation team did a first class job, with much attention to detail. We now have a new and more efficient system for heating our house and water.

We are happy to recommend them and will be using them for the maintenance of our new systems.

Thanks to all involved.

Complete re-plumb of Grade II listed property

A belated thank you to AHS for their tremendous work in replacing all our heating, hot/cold water pipework, radiators and boiler. A challenging and demanding project, AHS were the only company willing and able to take on the scale of the work and happy to work within the varying and dynamic constraints imposed by other simultaneous renovation works, Brexit supply-chain uncertainty and the restrictions of the Grade II listed structure (including working a weekend to ensure the heating was on following a hospital stay, for which we are very grateful).

AHS showed great attention to detail, helping guide the project from planning through to the eventual commissioning of the system, which they were able to bring online (thanks to some ingenious thinking) in two stages to fit around other works. From the very start, AHS were keen to help us get the system technically right: arranging for us to see an earlier installation, helping to plan the size of radiators, pipework and the boiler to ensure the final system would deliver comfort efficiently. They were happy to visit on multiple occasions to answers questions and carefully design the system around the needs and constraints of the building. The new boiler replaces an old inefficient system which left the house feeling perpetually cold and lacking in hot water. The new efficient boiler, with its intelligent ‘set and forget’ weather compensating controls, is performing remarkably well and has vastly improved the overall comfort of the house – delivering a consistent, comfortable and uniform temperature throughout the building. The new pressurised hot water system with a pumped secondary return is supplying us with endless quantities of consistently hot water and has a transformed the shower.

The build was led by an expert team of engineers who were happy to discuss and advise on the technical aspects of the installation, suggesting improvements to the overall design. AHS were meticulous and thoughtful in all aspects of their plumbing and pipework routing which was a considerable challenge because of the complexities of the old property. Where pipework had to be surface mounted, AHS were very careful to ensure the pipework was mounted carefully so that it ran straight and level. The end result is a work of modern art - being aesthetically pleasing and enhancing the overall look of the room. The boiler room installation was completed to a very high standard and AHS were able to fit the boiler and hot water cylinder into a small space thanks to some thoughtful pipework routing, which they carefully lagged - demonstrating AHS’s commercial pedigree.

Where snags were found (to be expected on a project of this size), AHS were prompt and courteous in fixing. It was clear that AHS take real pride in their work, always seeking to ensure that the build met our expectations.

We are very happy with the installation and the team’s careful, professional, methodical and tidy approach to their work. I highly recommend AHS for all aspects of heating and plumbing (no job is seemingly too big or too small). They are a first rate and friendly team who are very knowledgeable and highly experienced in all aspects of Veissmann and heating/water systems in general, giving very sound and helpful advice. Communications with the office were excellent and very helpful throughout. Thank you very much AHS for a job well done!

Boiler Replacement

An AHS engineer found that my boiler was emitting fumes and was beyond economic repair. This was a Monday morning of freezing temperatures and snow on the ground. My concern was to obtain a quotation for replacement and how long it would take for works to begin. I received a detailed quotation within two hours and the promise of work to replace the boiler within 48 hours. Later that same day AHS rang to say that they had obtained a replacement boiler and would begin work on the following day, Tuesday. The work was carried out by two excellent AHS engineers who found other failures in my system, which they repaired. They were punctual, professional and polite and I now have a fully functioning and most efficient boiler. Well Done AHS !

by Mr McB on AHS Heating Services

Following a breakdown in the middle of a cold snap I contacted a company posing as a local family concern, which proved to be anything but. After a wait of four days in the bitter cold I was told that no one could could come to see me for another two days because they were busy on a big job.

I called your company, an engineer called the next day, condemned the boiler (not a shock as it was 50 years old ) and sorted out emergency heating, the new boiler and system was fitted with a minimum of disruption by a cheerful and efficient team to the quote given and left clean and tidy, I was at all times kept in the picture. Since, I have never been more comfortable in my house.

Thank you again for your kind attention to my problems, I would recommend you without reservation to anyone needing such work carried out.
