Wall-hung water heater now comes in condensing version
Andrews has introduced to the UK market what it claims to be the first commercial condensing gas-fired continuous-flow water heater for wall mounting indoors. The condensing FASTflo offers efficiencies of up to 103% net. This new 56 kW model has been redesigned internally to accommodate an additional heat exchanger and condensate collector. The new product looks no different to its non-condensing predecessor and is exactly the same size.
These units modulate the burner to deliver hot water with an accuracy of ±1 K. With a temperature rise of 45 K, up to 1.8 l/s can be delivered constantly.
Up to six heaters can easily be installed in cascade configuration that needs only one remote controller, which can also regulate the circulation pump. The controller can also change the priority for run and standby mode.
FASTflo can be combined with the Andrews range of ST storage cylinders to provide large volumes of hot water for intermittent and large peak demand such as hospitals, hotels and sports facilities.
