Andrews has introduced the first commercial internal wall mounted condensing gas-fired continuous flow water heater available on the UK market, the condensing FASTflo, which offers efficiency levels of up to 103%.
FASTflo water heaters have been a staple in the Andrews portfolio for some years. The brand new 56Kw condensing model has been redesigned internally to accommodate an additional heat exchanger and condensate collector but, surprisingly, it looks no different to its non-condensing predecessor and is exactly the same size, which is no larger than a small suitcase.
The FASTflo range has been developed for commercial applications where there is a constant requirement for hot water immediately on tap. These units have a revolutionary design that measures the incoming water flow and temperature via the primary circuit board, before modulating the burner up or down to meet demand within +/- 1°C accuracy. With a temperature rise of 45°C, up to 1.8 litres/second (108 litres/ minute) can be supplied constantly within a temperature range of 37°C to 80°C and the auto ignition ensures there are no standby heat losses when the unit is idle.
