Somewhat vague but I'm after some remote diagnostics if at all possible - to the save the house freezing if something simple.
Now unoccupied, house recently fitted with a 'high efficiency condensing combi boiler' system - Betacom Glowworm. Available paperwork shows 'A flow controls x3' - heat in, heat out, water? Are these simple main elec valves?
Some problems with original install but this is a new fault we think. Boiler in bungalow loft - can't easily see what is what.
Fancy room stat, working okay. Has been left set at 14.C (cool part of the property). Usually okay, maintains it well (normally within .5C).
On a few occasions now when the left for c.5days, the temp is not being maintained (said 7.C last time) yet room stat looks okay (shows heat demanded). Rads cold. Run the hot water, goes hot/tepid,cold,hot as normal. Rads now start to warm.
So is something shutting of the HW system and getting reset with HW demand? But boiler can't be sitting in a failure mode as always HW works on demand.
I don't know anything about combis, only 'old stytle' setups. I would assume indirect heating for HW or is this wrong.
