Hi, I am Szymon Czaban

I am your local gas and heat pump engineer. I am based in Surrey (Frimley Green, GU16) and I serve Surrey, West London, and surrounding areas.

I have years of experience in the installation, repair, and maintenance of domestic plumbing and heating systems. I specialize in super efficient central heating and hot water installation using: gas condensing boilers, air source heat pumps, unvented and vented hot water cylinders, properly calculated and sized pipework and emitters for radiators, and underfloor heating.

Please explore this website for more information on how I can help you design, install, maintain, or improve your heating and hot water system.
