    the basic problem with TRV's and roomstats when fitted together has always been the same, lack of understanding on the part of the homeowner and lack of information from the installer. TRVs were originally designed to operate independently of any other controls besides clocks, each TRV could...

    Boiler replacement or upgrade

    like all open flue boilers it is perfectly safe as long as it has adequate ventilation, a working flue and is correctly serviced, however it is not as inherently safe as a room sealed boiler, Viessmann boilers can be fitted into an open flue with the correct kit. they are fully pumped and wall...
