Recently moved into ths house and have had the heating on as well as the hot water. I've recently noticed that the central heating pump (Grundfoss) is running all the time. The only way to stop the pump is to switch the whole system off. Other that that it is all working perfectly, heating working when I need it in every room and loads of hot water. Just this pump running that is keeping me awake at night.

make sure you have the fan switch set to AUTO and not FAN. Or it will run all the time.
I have had the repair man come and supposedly fix my central heating unit from running all the time. If it decides to heat the fan will kick on. But when it has reached the appropriate temp it will not shut off unless i turn the whole unit off. And then it may or may not heat again once turned back on. So I feel you pain right now.

Its more likely to be a pipework problem as in the relationship of the pump to the vent(I am assuming that the pump is installed in this order). Rise /flow from boiler rising up to vent and tank, cold feed from tank tee'd off this and then pump pumping away from vent.If this has been going on a while you will probably have sludge problems as well now and probably thin radiators.If you cannot see the problem I suggest getting in a professional. Edit Exracer 2 This is a UK open vented system not a sealed sysytem, it has an open topped tank not a sealed pressurised expansion vessel. John the problem is 'Pumping Over', that means that with the system running water is being pumped out of the expansion pipe. If it was a heating coil leak whichever of the feed/feed expansion tanks was lowest would be running to overflow not pumping over,

Not sure exactly what you have here. It sounds like you might have a recirculation pump for your hot water. If that is truly what you have then I would say its normal for the pump to be running all the time. Its keeping hot water throughout the house. If this is the case what you might do is get someone to wire in a timer so that the pump doesn't run at night while you sleep.

It sounds to me that you are talking about the hot water boiler system. Grundfoss is a brand of pump which circulates water through the radiation loops in the house. It also sounds like your potable hot water system is also controlled by the boiler............either by way of a separate storage tank like a boiler mate or with an internal series of loops incorporated into the boiler. regardless, this pump must be on to circulate or distribute hot water to where it is needed.

My 4 yo heat pump did this and since we had just bought the house we had a home warranty inspect it. It turns out the entire system needs replaced. heat Pumps are horrible they are noisy and dont work as well as a good old gas furnace. Replace your heat pump with a gas furnace and you too will feel the difference.

it must have been wired to run continiously to circulate water so that when you need heat for your space heater, the water is already hot and ready to use. other than that, i can't find anymore reasons why will it stay on constantly.

It is running all the time so you have hot water and heat all the time.

On some units there are actual reset buttons (on the outside unit itself) If there is on yours try that.

have your local plumbing contractor take a look at it.
sounds like a limit control non-functioning correctly
