The Wijas water heater is the smallest on the UK market, measuring just 152 x 135 x 72mm. These non-vented heaters easily fit under a sink or in a cabinet to provide point of use water heating. They are extremely energy efficient too and you don't waste lots of running water waiting for the hot water to arrive. They can be used with ordinary taps and therefore providing a much neater and easier solution to a wall mounted over-sink heater.
Please note that this unit too powerful for connection to a 13A ring main and must be wired to the electrical distribution unit.
