What no-one else has meantioned/asked is whether the plumber fitted
proper TRV valves on the radiators and fitted a room stat. Since this
is a new system then building regulations do require him to do this.

..and on systems with new boilers. AIUI.



We asked for TRV to be fitted on all radiators but there is no room
stat, except for the orginal one in the dining room.
