One Power Showers Question – Can a power shower be used in conjunction with a combination boiler?
Answer – Under no circumstances can a power shower be fed from combination boiler. This is because power showers incorporate a pump, and the W.R.A.S. (Water Regulations Advisory Scheme) dictates that mains water – which is what feeds a combination boiler – cannot be pumped. Contravention of this water regulation carries a substantial fine. Power showers can only be installed on a conventional gravity-fed plumbing system comprising of a cold water storage cistern and a hot water cylinder.
