We have moved to a new house and have found 2 hot water tanks in the loft.One of the tanks feeds wash basins and kitchen sink with hot water, the other tank feeds a single bath with hot water. I cannot see why I need this extra tank and plan to plumb the bath to the single tank. My problem is, not being a heating man, the heating coils run first through the tank I don't want, then into the other tank. As I dont want to disturb this pipework, will it be ok to have this coil running through a dry tank. There is no thermostat on the bath tank, only on the other. It really is odd. I just think my main single tank would heat up quicker, be cheaper to run and supply enough hot water for just the 2 of us. Showers are electric. Please give me your thoughts on this matter. I am not touching anything without positive guidance. Thankyou.
