Boiler installation in Chiswick
We have a large period home in Chiswick with several bathrooms — combi or cylinder?
For most of Chiswick's substantial Victorian and Edwardian homes, a system boiler paired with a Megaflo unvented cylinder is the better choice. It delivers strong mains-pressure hot water to several bathrooms at once, which a single combi can struggle to match in a larger house.
Can you install underfloor heating in a Chiswick kitchen extension?
Yes — wet underfloor heating is one of our most-requested jobs in Chiswick's extended kitchens and rear additions. We design and install the full system to the finish standard expected locally, and tie it into the boiler or heat pump.
Which parts of Chiswick do you cover?
All of Chiswick including Chiswick High Road, Turnham Green, Strand on the Green, Grove Park and Bedford Park.
