Hi all, I'm looking at 2 no. housing units - 1 no. 2 story 75m2 on the GF and 55m2 of the FF. UFH on the GF and Low Temp Rads on the FF. The second unit is 200m2 bungalow all UFH. Both have an air to water heat pump. Both Air to Water heat pumps have an inbuilt heating circulating pump and, based on the HP manufacturer recommendations, the built in circulating pump is sufficient in both cases, For these 2 housing units (which are larger than what I normally work on), do you think that the HP integrated circulating pumps are generally sufficient on their own? Thank you,
