The New Viessmann Vitoden Boilers are here!

The new Vitodens 100-W & 111-W ‘connected’ boilers are now available from Viessmann, the range offers high efficiency gas condensing boilers, which are loaded with features for easy installation, high efficiency and impressive fuel savings.

Product features:
  • NEW user friendly control via backlit LCD touchscreen.

New Vitodens Display

  • NEW improved modulation ratio 1:6.
  • Wall mounted gas condensing combi & system boiler 4.7 to 35 kW.
  • Energy efficiency class: A.
  • 10 year warranty on the Inox-Radial heat exchanger.
  • Modulating stainless steel cylinder burner.

Straightforward access from the front, so no need to leave space at side for maintenance.

NEW: Viessmann has added the Vitodens 111-W to its warranty options. It will be the same offer as for the Vitodens 100-W and at the same prices.

All 100 range models installed since 2007 can be WiFi enabled, with a control accessory, on sale from September. Unlike previous boiler apps, which connect with thermostats, this is the first to connect with the boiler.

Inox-Radial Stainless Steel Heat Exchanger

Heat Exchangers: Stainless Steel v’s Aluminium

Stainless steel is the key and here is why. . .

Heating technology should work together to ensure the smooth operation of the entire system – from boiler via burner, control unit and heat exchanger, to deliver the highest possible operational reliability.  Today, domestic and commercial boiler technology demands the most reliable, energy efficient components.

A key component in choosing the right system, is the heat exchanger within the boiler, as maintenance costs, durability and product lifetime should all be considered when buying a boiler. As the two most common types of heat exchanger in the UK condensing boiler market, we have examined the differences between stainless steel and aluminium to offer a comparison of quality and longevity.

Stainless Steel Heat Exchangers:

Used by Viessmann throughout its entire condensing boiler range, stainless steel heat exchangers provide a high resistance to corrosion in a wide variety of pH levels, therefore increasing the useful life of your boiler. This provides long term value for money and requires less system downtime due to maintenance.

Important points to consider:

  • Increases useful life of your boiler.
  • Less downtime due to maintenance.
  • Does not require use of system inhibitors.
  • Recommended for filling with potable water (drinking water) no inhibitors required.
  • Self-cleaning.
  • Higher grade corrosion resistant material.

Aluminium Heat Exchangers:

A lightweight and alternative option, Aluminium heat exchangers also provide high heat transfer but require special inhibitors when maintaining the system, which if not used can result in a high risk of damage to the boiler. Annual maintenance is also vital to remove aluminium oxides, which can build up and clog the condensate line.

Important points to consider:

  • pH treatment critical to longevity of the heat exchanger.
  • Artificially softened water not permitted.
  • Aluminium material corrodes through aluminium oxide build up and erodes further at high flow rates.
  • Reduced lifetime of the heat exchanger.
  • Cheaper to manufacture than stainless steel.

Heat Exchanger Steel v's Aluminium

All Viessmann gas condensing boilers are equipped with stainless steel Inox-Radial heat exchangers. This technology brings with it an extremely high efficiency rate of 98 percent and exceptionally reliable and efficient operation during its long service life.

Viessmann guarantees the Inox-Radial heat exchanger for ten years against leaks resulting from corrosion.

New Boiler Installation

Proud of our Engineers – Viessmann Installation at a New Forest Hotel

It’s hard not to be impressed at the work our engineers undertake especially when it comes to an installation such as this.

What a beautiful building for the installation to take place at.

Now down to the main plant room. . .

Two Viessmann gas boilers installed and awaiting to be fully connected and turned on.

To an untrained eye, such as mine, even I can see the work that has gone into this Plant Room by the sheer size of the new cylinders and pipework.  All the old dropping pipework is coming out to be replaced by new straight and completely secured 2 ½” iron pipework and fittings.

IMG_8540

This not only shows the magnitude of the work involved, but that careful thought and design consideration has been made, to fit into the space available and to make all the equipment accessible and serviceable in the future.  Not forgetting that until it is time to switch over to our new system the old system has to be running as the hotel is fully booked as the work continues.

The Technical Side:

I would like to give you a rundown of the equipment used in this installation:

– 2 x Viessmann-W 200 Vitodens 60kW boilers
– 2 x Viessmann Vitocell 300-B 500L Cylinder
– Viessmann Low Loss Header and insulation
– Spirotrap MBL 2 ½ “
– Spirovent Dearerator 2 ½ ”
– Pumps
– 2 ½” Pipework
– Controls – Weather Compensated

Which means:

Our customer will have complete control of the heating and hot water system within the hotel.

The main plant room has 1 underfloor heating circuit for the conservatory, used as the dining room.  Then 3 individual fully weather compensated heating circuits for the main house ground floor, 1st floor bedrooms and 2nd floor bedrooms.  Meaning different temperatures and timings can be set for the different sections of the hotel.

So from an atmospheric conventionally flued system to include boilers and water heaters, they now have a balanced system with Viessmann high efficiency condensing technology with full weather compensation.

What a difference we can make!
