Weather Compensation Technology

By taking advantage of Viessmann weather compensation technology, you can save an amazing 15% extra on your fuel bills.

Not only could you be saving money, but carbon emissions too. Which need to be net-zero by 2050, accordingly to the latest government guidelines, so a step in the right direction.

New conventional boilers offer a saving of 35%, with an opportunity to save an additional 15% if you invest in Viessmann’s weather compensating technology with very clever controls.

Technical Information:

So how does it work? In short the weather compensation controls ensure the boiler burns exactly the amount of fuel required to match the heat loss from the building.

A small temperature sensor is located on the outside of the building. This is wired into the internal controls of the boiler and information about the outside temperature is sent to the boiler controller constantly.

When the temperature changes outside the boiler responds and starts to increase or decrease the radiator temperature to compensate. This pro-active mechanism means that people inside the building won’t even notice that the temperature has changed.

So weather compensation controls enable the boiler to respond to outside temperature changes and adjust the radiator output, to maintain a constant temperature indoors.

The diagrams below shows the comparison of a heating system without weather compensation.

This also means the boiler isn’t working to hard, which in turn adds to its life span.

Condensing Effect:

Viessmann weather compensation technology enables the condensing boiler, which already has dramatically increased efficiency, by recovering latent heat in the flue. But also by enabling the boiler to operate at lower temperatures meaning it can condense for longer.

Controls:

The Viessmann Vitodens 200-W weather compensating controls are very sophisticated. Giving a heat curve that can be adjusted to finely tune the household and the type of building construction. These controls also gives you the added benefit of:

  • Night set-back option.
  • Built-in 7 day programmer.
  • Built-in pump logic for optimised pump over-run to reduce power consumption.
  • Morning booster function, it lifts the flow temperature by 20% first thing in the morning to heat the house faster.

Out with the Old

Out with the Old . . and in with the New.

Out with the old and in with the new. Another new Viessmann Vitodens 200-W boiler installed and another happy customer in Abbotts Ann, Andover.

We removed an old boiler and cylinder, as the customer had concerns about storing the water in the loft. For instance the damage the water could cause if it were ever to leak.

Having experienced issues with the the old boiler, our customer from Abbotts Ann, Andover decided it was time for its replacement. So it was out with the old and in with the new!

Technical Information:

We, therefore installed a Viessmann Vitodens 200-W B2KF 26kW combination boiler, complete with horizontal flue and weather compensation. As with all of our installation we carried out a powerflush of the system. Along with the installation of a Spirotech magnetic filter to protect the boiler from debris which appears over time within all heating systems. The Viessmann Vitodens boilers have been voted Which? best buy for the last 4 years. Showing that they are loved by consumer and installer alike.

Weather Compensation:

The Viessmann 200-W is fully weather compensated, which is amazing Viessmann technology giving the boiler the ability to measure the outside temperature and adjust the boiler output accordingly. The weather compensation ensures that the radiators will feel warm, but won’t get very hot and then cool, meaning you have a steady temperature throughout. Meaning huge savings on running costs, which can be up to 15%. Not to mention the importance on being more eco-friendly.

The Viessmann 200-W 26kW combination boiler also delivers 13 litres of water a minute. Which given a standard shower needs 9 litres, gives ample hot water. With the removal of the cylinder the customer also gained more space in the cupboard.

Viessmann offer a 5 year manufacturer parts and labour warranty as standard for complete piece of mind. With options to extend the warranty to 12 years if desired.

We are delighted with the work done by AHS. Their engineers are a pleasure to deal with and took great care to ensure that the installation is as neat as possible. This is the second time that we have used AHS and will certainly use them again in future requirements.

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.”
