Central Heating - That time of the year again...
I'm looking for clues on where to look with a non-working central heating
system... The house has: Oil-fired burner/boiler Hot water tank Control box for hot water/ central heating - hot water is working fine, boiler fires up etc etc, central heating has been turned off over summer Single room thermostat - set on high... TRVs on each radiator - set on high... Have bled all radiators It *feels* like there's no signal to to boiler to say give me heat - (tho, as I say, works for hot water) Should there be a 3-way control valve (over and above the TRVs) somewhere that I should be able to see? Help... Graham |

Help... Graham if its firing up on HW sounds as if the pump is stuck for the CH, if all revelvant lights say its coming on. Give the pump a nice slap with a small hammer, mines done it a few times after being stood over the summer months, nowadays I run it for a bit at least once a month. |

Or you undo the chrome screw on the back and rotate the shaft with an electrical screwdriver or something. Have a towel handy to collect the drips -- geoff |
