Radiant floor heating using heat pump?
We live in a Zone 7 area and are building a one story 2000 sq ft on a slab and have decided we would like to heat the house with in-floor radiant. We have been told by HVAC specialists that the best solution would be geothermal, followed by hot water heat pump, electric hot water, then forced air heat pump and electric radiant. We don’t have natural gas so that is not an option. Geothermal is out as it is nearly three times the price of the other solutions and this is a retirement home.
The second solution we had not heard of. It was described as a heat pump with a hot water tank or boiler that heats or cools the water similar to how a forced air heat pump works but heating and cooling water instead of air.
I am waiting on pricing for this and the electric hot water solution. I found many old discussions on hot water heat pumps but they were small units to replace hot water tanks.
Is the order of solutions logical and what can you tell me about the efficiency and comfort of the hot water heat pump solution?
