Energy Efficient, A-Rated Boilers

The average life span of a boiler is 12 years and a gas fired boiler accounts for around 55% of what you spend in a year on energy bills, so an efficient boiler makes a big difference. If you were to replace an outdated gas boiler with a new, A-rated condensing boiler, you will save on average £300 per year and significantly reduce your carbon dioxide emissions. For more information, please see www.energysavingtrust.co.uk. We are the Durham specialists in the supply and installation of energy efficient heating systems. As well as being more environmentally friendly than conventional gas boilers, they also will pay for themselves within 6-7 years, meaning they’re a shrewd investment too. We are able to provide exceptionally competitive prices for new boilers and can get extended product warranties due to our enhanced agreements which we have negotiated with our suppliers.

Combi boiler Installations Durham

Combi boilers are the UK’s most popular sort of boiler for gas central heating and domestic hot water. They are very easy to install, simple to operate and cost effective to run.

A combi boiler installation in Durham only heats water when a hot tap or shower is activated, ensuring maximum efficiency. You don’t have to find space for a water storage cylinder or have a tank within the attic room. Hot water is shipped to your taps at mains pressure, so you can enjoy a powerful shower without the need for a pump

System Boiler Installations Durham

A system boiler heats your central heating system directly and delivers hot water for the cylinder.

A system boiler, just like a regular (conventional) boiler works on the basic principle of stored hot water. However, a system boiler is different from a regular boiler in a number of important respects.First of all, most of the important individual components of the heating and hot water system are constructed into a system boiler, which means installation is faster, neater, less complicated and much more efficient.Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more cost-effective running costs. The system boiler removes the requirement for a feed and expansion cistern.

Heat Only Boiler Installations Durham

Heat only boilers are also known as ‘regular’ or ‘conventional’ boilers. If you are replacing an old boiler and have a small expansion tank and a larger cold water storage cistern in your loft space, most likely already have a heat only boiler.

Heat only boilers are typically installed on an open vented system. The system will often comprise two tanks in the attic, a hot water storage cylinder in the airing cupboard and a separate pump.
