Hi everyone
We inherited a heating system in our house with a grundfos UPM3 AUTO L which is connected to the hot water cylinder to push hot water around the house.
But I have no clue if it's set correctly or how it works. The valve to it had been turned off by the previous owners. Hot water takes ages to get to the end of the long run.
With the circulator operating obviously it comes through quicker.
I've read the grundfos pump info but all it tells me is that there certain curves. What curve should it be set to, what do they mean?
What I'd like to know is what should it be set to and is it a false economy? What I'm wondering is if it circulated the hot water from the tank around the house - surely it will eventually cool the whole tank down and I'll be spending more money heating the water to keep it circulating warm.
My family complain that it takes about 3-4 minutes to get hot water from the tank when the circulator is off but obviously we're pouring gallons of cooled water from the pipes down the drain.
What's everyone's thoughts and advice please because I don't know if I'd be better off leaving the circulator on but therefore constantly heating it costing a fortune in gas. Help!
Thanks
Andy
