Hi, I have a hot water system with solar heating for the water.
The heating works, the hot water is also heating in the cylinder but when I turn on the tap, after initially running hot, it goes to lukewarm.
If I run two hot taps it seems to then be hot but as soon as I turn one off, it goes back to lukewarm again.
There are two 3way grundfos pumps in the loft. One seems to be ticking, the other is silent.
Anyone out there have any good ideas before I take a hammer to it all
Thanks
