Total Efficiency


Typical grid efficiency


Is Gas Environmentally friendly? 


Natural gas is a finite resource which is used in many countries to produce electricity.  It is not renewable in the same way solar and wind is as we cannot make more of it or rely on an infinite amount.  There are ways that natural gas can be more environmentally friendly though, as the Vitovalor will replace a low-efficiency heating and hot water system it will reduce consumption.  Vitovalor produces electricity at a higher efficiency than a traditional power station and does that as a by-product of heating the home.  The total reduction on each homes carbon footprint is around 30%, due to reducing your reliance on old power stations that deliver at an average of 34% efficiency. Whats more, the flue cell unit, unlike traditional gas boilers, does not actually 'burn' gas. It uses a process called 'cold fusion' this gives of only the carbon dioxide byproduct, and none of the harmful NOx emissions associated with burning fuels traditionally


What government incentives and grants can I benefit from with my boiler/ CHP Installation?

The main incentives consist of the following;

-A reduced rate of VAT from 20% to 5% on your heating upgrade.

-PACE funding on the installation of around £6500

-RHI, The renewable heat incentive pays you 13.59p per kW of electricity produced, and an additional 5.09p per kW of Electricity exported.

When are the incentives guaranteed until?


PACE funding is available whilst still in the EU. Reduced VAT is available for the foreseeable future. The RHI is guaranteed for 10 years from purchase, however this is only available if purchased before April 2019. We are not yet aware what is available after this date.


How does it work?


The Vitovalor has only the same connections as a standard combination boiler.  Heating, hot, cold and gas pipes.  It splits the natural gas into Hydrogen and Carbon Dioxide molecules, the hydrogen is then used to create heat and electricity through a fuel cell process.


Is it dangerous?


Hydrogen can be dangerous when stored in volume. However, Vitovalor 300-p does not store any Hydrogen, once it has been created it is used instantly ensuring there is no danger.


What's the cost of a Vitovalor 300-p?


Of course all installations are different and we would never commit or expect our customers to invest without a full survey and home energy calculation to maximise your savings and return.


Prices start from £11,000 and we have some customers with bespoke systems specified at over £30,000.  These are not cheap but the savings, incentives and reliability of the product make it an unrivaled home energy solution.

As you can see prices vary a great deal, please use this estimate form and we can give you a much better indication.


How big is it?


  A standard Vitovalor unit needs an installation space of about 650mmx1100mm and is approximately 2m tall. This won't fit in your kitchen cupboard.  It is ideally suited to a utility room, garage or if you are fortunate enough, a purpose made boiler room.

Vitovalor average efficiency

​​​​​​​Is it noisy?


No, It's no more noisy than any other modern gas combi boiler.


How can I benefit from Vitovalor?


If you have an old boiler, cylinder or both, Vitovalor will reduce your fuel costs as well as qualify you for multiple incentives.  We will happily give you a free estimate for the ten-year costs and savings. Please contact us here if this is of interest to you.


Can it do underfloor heating and radiators?

Absolutely, it can replace any modern gas boiler, and much much more!


How much hot water can it provide?


The Vitovalor is compared to a 250l unvented cylinder, this means it is capable of providing for an average to large family home at high pressure.  Usage above this can be catered for with an upgrade.


Will my gas bill go up?


Unless you already have a new Viessmann weather compensated boiler your gas bill will not go up.  Although the Vitovalor burns a tiny amount more gas than it's little brother the 200 range, it is vastly more efficient than older boilers and even modern competitors. In any case, the large reduction in electricity bill would negate any tiny increase in gas consumption.


How long does it take to install?


Again, all systems are bespoke but anything from two days.


What does the guarantee cover?


Viessmann cover all parts and labour within the fuel cell for breakdowns and failure for ten years. The RHI is also guarenteed for 10 years.



What other advantages are there?


Being less reliant on the grid, less reliant on dirty power stations and having your own production facility.  Vitovalor also allows you to accurately forecast the long-term heat, hot water and electrical costs for your home.  This makes you more resilient against the rising cost of electricity. 


What is PPA?


PPA stands for a Power purchase agreement.  This is an agreement between two parties, it could be the homeowner and another energy user, or home owner and energy provider.  The homeowner could sell their unused self-produced energy for a profit.  It could also be an agreement between an installation company and a property owner.  It will give you a way to maximise return on investment.

We will be happy to provide a free consultation with 10-year payback forecast and quotation of installation cost.
We are also happy to give an estimate based on the following questions, but will always conduct a full site survey before conducting any work.
