More traditional in its design, Express is our original, tried and tested water heater. This water heater has been much loved by our customers over the years, so much so that they want it time and again either when updating properties or installing in new premises. Adaptable to under-sink and over-sink installation Express has a tough metal case, making it easily capable of withstanding the rigours of daily use. Express is available in three sizes and two ratings and can be fitted with a telescopic spout for over-sink or to taps under-sink.
