So we are going to install a 500l thermal store into the utility room. This will create quite a bit of heat I suspect and it would be good to spread this round the building. In fact next to the utility is the integral garage which is full insulated - 60mm internal insulted PB, triple glazing and an insulated garage door. Would it be mad to put a single room mvhr system between these rooms to gentle heat the garage with the excess heat from the the TS?
