Extension underfloor heating is something you should consider when planning an extension to your home.

Extension Underfloor Heating keeps your space free of clutterWhile extending your existing central heating may seem the obvious answer, there can often be practical snags.

Maybe your boiler doesn’t have sufficient capacity?  Or if the system is a few years old, are you sure there isn’t any sludge or sticking valves?

If the old system isn’t up to the task it may make it hard to balance the extended system without causing problems in the main part of the house.

And in any case, wouldn’t it be better to build in something maintenance free, future proof, and with room by room zone control?
