Hi, I have a ferroli sigma 40-60 boiler in the kitchen. This has a pump over run circuit to the pump in the airing cupboard. The problem is that when the timer and the room thermostat call for heat this starts up the boiler BUT there is a fault on the boiler PCB in that it does not send the live signal to the pump to start up ...... result much banging and rumbling of pipework and boiler as the boiler is on but without water circulation!
Everything else is all fine it is just the pump circuit that is the problem.
Before i either get the boiler fixed or replaced, if i wire the pump to permanent live (with a manual switch) then the pump will be on all the time the manual switch is turned on.
The heating timer is to come on at 6pm and off at 9pm.
If i turn the pump on manually at 5pm and then the timer makes the boiler come on and off between 6pm and 9pm and then i turn the pump off manually at the switch at 10pm, is this ok in the short term?
I realise I need to make 100% sure i turn the pump on manually for this at the stated time.
The other alternative is to leave the pump switched on and running 24 hours. Would this be ok too? I realise this will probably shorten the pumps life though? would it? Again this is just a short term solution until i get the money to get it properly fixed.
Thanks for your comments and advice.
