I have a bungalow which is currently being done up. There is a water tank in the loft which I would prefer not to be if possible? An Economy 7 water cylinder will supply hot water based on ground floor. Heating the bungalow will be storage heaters. What advantage is there to keeping a water tank in loft? (a bad exp. with a tank leaking through ceiling in past has made me cautious). Which shower can I install? Any advice? K
