Afternoon all
We've recently had a significant amount of building work done, including a loft extension.
The current Grundfos UPS2 15-50/60 is very much on it's way out (making a fair amount of noise, historically very much struggled to get heat to the living room).
After the work, we have the following.
3 * Towels rads, 1 * hall way rad (about 3kw) 2 * rads in the living room (about 8kw's between them).
Kitchen underfloor heating with it's own pump (also needs replacing, water on the ouput of the loops never gets particularly warm).
1st/2nd floor are all on underfloor heating (again, a dedicated pump)
Office/stock room with underfloor heating, not yet sure if that will have it's own pump) not yet finished.
Sealed hot water tank, heated from the boiler
Hight difference between Pump and top of the highest Radiator is ~7m
The boiler is an ATAG i32R heat only boiler.
My question is, would a Grundfos Alpha3 15-80 (130) be a suitable replacement for the ailing UPS2?
