We first removed the old heat only boiler and cylinder and installed a new Valliant ecoTEC exclusive with Green IQ combi boiler. We re-ran gas pipes, in the right size pipe for the boiler, and conducted a complete thorough power flush on the system. We further installed six honeywell thermostatic radiator valves, filled the system with anti-corrosion inhibitor and vented all radiators. We completed by fitting magna clean professional 2 to protect the boiler from any sludge build up. Because we are Approved Advanced Valliant Installers, our boiler installs come with either a 7 or 10 year guarantee, depending on the chosen boiler.
