We’ve been lucky enough to win some awards and we’re proud to be the 2020 “Installers of the year”.

Award Winning Installers working with Award Winning Appliances

In terms of cost and environmental impact, boilers that are over ten years old waste a lot of valuable energy. In fact, many older boilers waste up to 40% of the fuel they burn instead of converting it to heat.

You should be aware that current building regulations state that any replacement or new gas-fired boiler must be a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat which will impact your home heating bills, as well as the environment.

We specialise in the installation of renewable energy products and condensing boilers, using the latest technology available. Modern condensing boilers improve efficiency to over 90% which could save you at least 30% per year on your home heating bills. A big saving over the lifetime of your boiler!

Depending on your heating and water demands there are different types of condensing boilers that are available. Please have a look around our site to read more about how we can help.

Solar Heating & Hot Water

Solar thermal energy is probably the best known and most popular form of domestic renewable energy. The sun’s energy is collected by flat plate collectors or evacuated tubes (usually on the roof) which are orientated towards the sun in order to warm the property’s water naturally.

Contrary to common belief, a lot of solar energy can still be gained from solar collectors even on cloudy days. Manufacturers state that an average property should receive around 60-70% of the properties total hot water demands from solar thermal systems. 

Air to Air Heat Pumps

An air to air heat pump is an all-in-one heating and cooling system that is designed to provide year-round comfort.

The Greensource Air to Air Heat Pump converts energy from the air outside into heat inside and then circulates warm air, providing a comfortable temperature around the home.

As an extra benefit, Greensource Air to Air Heat Pumps can also operate as an air cooler and purifier using Plasmacluster Ion-technology. Get in touch with us to find out more.

Air to Water Heat Pumps

An Air to Water units provides hot water via a built-in hot water cylinder, making it an ideal replacement for an old or inefficient boiler.

They use a small amount of electricity and are in excess of 300% efficient. That means that for every kilowatt of electricity used, the unit will generate at least three units of heat. These boilers are designed to replace traditional gas and oil fuelled boilers based on the principle that electricity will remain more stable, and therefore cheaper, in the long run.

What Our Customers Think

Highly Recommended!

I just need to recommend John from Eco Gas London who came over to sort out a problem with the loo. Instead of charging us a small fortune for a call out fee, he talked us through how it could be easily rectified and didn’t charge us a penny.

This company is consistently good. Highly recommended!


Eco-Gas were great

Really happy with the work done. We had central heating installed from scratch, in three story Victorian terrace.
John was was extremely professional, approachable and understanding to our unique situation. There was good humour and he was open to answering as many questions-as we had. Communication with John and his team was very good, with job completed in budget. We would definitely recommend them to others and use again.

Excellent job

My elderly Mum moved last year only to find she had no heating and hot water. John came at very short notice on a Saturday evening and did not leave until he had the boiler working. A month or so later John gave us a competitive quote for a new boiler. He talked through our options and explained everything he was going to do.

My Mum is extremely happy with her new boiler and the service that John provided.
