i have a gravity hot water and pumped heating system, with a gloworm space saver mark 2 boiler, grundfos pump, siemens RWB29 programmer and siemens RAA20 room stat.
the room stat never operates because the temp in the house never gets above about 15/16 degrees and i want 19/20, however the hot water is scalding hot.
most of the rads seem hot but its just not warm enougb inside, especially now its so cold outside. i have even turned up the boiler and still no warmer, except the hot water!
any ideas what to do?
