We recently installed a water heater in a commercial premises on the Isle of Dogs London. The water heater is a small electric powered unit that provides enough hot water for hand washing etc this reduces the need to install a boiler for hot water or new pipework from the boiler which could be cited a fair distance away in the commercial premises. The water heater was connected with 15mm pipework from the cold water supply and also was connected to the sink tap. So the sink pulled its hot water from the electric water heater.
We now accept credit cards on site
