Heating a house with a diesel water heater (Eberspacher D9W hydronic) pt1

In this video I make my own hot water central heating system from some parts I can find in the basement and also on Leboncoin. Central heating systems in France, especially in a stone built farmhouse that is badly insulated are difficult to choose. I want to fit a heat pump but not sure if a low temperature one will work. So i had the idea of replicating the output of a heat pump (Low temperature) to see if it would work! This is kind of back to front but lets see if it works hope it helps AJ #Heatpump #Eberspacher #Centralheating #lowtemperature #heating #pipework
