Hi there,
I have been looking at installing a combi boiler in our bungalow.
Having done all the heat loss calcs for all the rooms (including the loft conversion) It rather looks like I don't need anything more than about 10kW for heating.
However, she who must be obeyed likes her baths, and to give a decent Hot Water flow rate I have been advised to go for something like a 28 to 30kW combi.
Would I be better off installing separate CH and HW boilers?
or will a 30kW combi modulate down so I am not wasting vast amounts of energy?
Any advice appreciated.
