High efficiency gas boiler installations

What is a high efficiency gas boiler?

A high efficiency gas boiler is what’s known as a condensing boiler. Since the 1st of April 2005 the condensing boiler regulations state that all new gas fired boiler installations must be condensing boilers, this also applies to boiler replacements as well. Before then most gas boilers installed in homes and buildings were non-condensing standard efficiency boilers. 

Are gas boilers still legal?

Although the government's aim in the long run is to utilise renewable energy sources wherever possible, right now this is not completely feasible for every property throughout the UK and can incur heavy installation costs making properties ready for such technologies for those that are, especially older properties with poor insulation and high heat loss. This means that gas boilers are still viable and will continue to be used for the foreseeable future.

What makes a high efficiency gas boiler a good boiler?

When choosing a gas boiler brand for a new build or boiler replacement it's important to choose a manufacturer with good heat exchangers, good modulation and good controls, as well as good quality and reliability obviously. As well as choosing the right boiler and controls for your specific needs it's also important to consider the condition of any existing system as this can impact the function of the new system if not taken into account.

    • Professional, polite and considerate

      "Really impressed with the level of service, from getting a quote and booking the job, to the excellent work done by Greg and Liam doing our upgrade to a Combi boiler. They were very professional, polite and considerate, happy to work around any problems and keep us informed of the progress, and the work looks to have been completed to a very good standard. Much appreciated!"

    • Tremendously responsive and good natured

      "I had to replace an old gas boiler that was no longer up to spec and there was some extra work necessary to ensure the flue could be fully assessible. VitoEnergy gave me a really great quote and did the job in rapid order - I was very pleased with the installation but had an issue with some of the flue routing. However - they were incredibly responsive, absolutely addressing the issue post haste and moreover pointing out and resolving another couple of issues on my gas supply that I didn't realise needed addressing. They are a tremendously responsive and good natured, friendly company and I have no hesitation in recommending them."
