Hi
I have a problem with underfloor heating. The upstairs radiators and boiler all seem OK. The pressure in the underfloor manifold is pulsing, I suspect due to the pump function. The pump is a Grundfos alpha 25-60. The temperature under the floor has dropped to 25 degrees C and the house is cooling slowly.
Any ideas of what the problem is?
Thank you
