Having moved to this (large old) house in the summer we have finally had our (old inefficient, oil fired) boiler serviced and the heating is back in commission. I have replaced the wall mounted room stat in the draughty hallway with one in the lounge, which seemed sensible. All is now fine (house is warm) but one thing seems a little strange.
The room stat turns on and off roughly as expected, and the circulation pump turns on and off with it. The boiler will cut in as expected as the stat calls for heat, but will then turn off a few minutes later, although the pump continues to run and the stat is stall calling for heat.
The engineer who recommissioned the system explained that this was the boiler switching off as the water circulation temp reached that set by the boilers internal stat (it has a control comprehensively marked 'off.. medium.. high'.
Is this behaviour to be expected - is it simply my boiler heating the water faster than the radiators can radiate it and thus allow the return to be cool enough to warrant heating? I currently have the control set midway between medium and high and the rads are 'painful hot' to touch.
My understanding was cycling an oil boiler was inefficient - it certainly sounds like its taking a lot of oil with it every time it fires up with a little shudder!
Any info much appreciated, and yes i do realise the most efficient resolution would be a new boiler, just not this winter!
Thanks in advance.
