Despite my dislike of instant electrically heated showers I've been overruled and fitted one in a shower room for a staff bungalow that's being renovated. The property will also have a 21kW combi boiler which would do a better job and I was just wondering if there is an electric shower that instead of having a cold feed could accept ta thermostatically mixed feed from the combi and only cut in if the combi wasn't providing hot water for any reason.
