Combination Boiler

Combination Boiler and Gravity Fed Systems

If you are having a loft conversion and have a gravity fed system it is likely the cold water storage tank in the loft will need to be re-located to the eaves area. The  Immersion Heater is usually located in the airing cupboard on the 1st floor landing/ hallway. This may also need relocating to allow for the new staircase. A negative head water pump will need to be installed alongside the immersion heater to pump hot water to the new bathroom. This expense can be put towards a new combination boiler.  

A combination boiler is a high-efficiency water heater and central heating boiler, combined within one compact unit. No separate water tank in the loft or hot water cylinder required, offering space for the new stairs and loft conversion. An ingenious space-saving idea, and a popular choice with all our loft conversion designs.

All domestic boiler installations in the UK must be carried out by an Engineer who is registered with a competent person’s scheme e.g Gas Safe Register.  The Gas Safe Register replaced CORGI as the gas registration body in 2009.  All our combination boilers are installed by our Gas Safe Registered Engineer, giving you total peace of mind that your boiler has been installed correctly and meets all the regulations.
