Condensing boilers with integral DHW heating are available for all those places where space for a heating system is a little tight.
Wall-hung gas-fired condensing combi boiler (C)
A combi boiler is often an ideal solution for heating small homes because it requires so little space. An efficient stainless-steel plate heat exchanger heats the DHW instantaneously as it flows through the boiler. This enables DHW to be drawn off at a rate of up to 14 litres per minute.
Compact,free-standing gas-fired condensing boiler (K)
The compact unit integrates the condensing boiler and a cylinder within the same housing. The inside of the cylinder is protected from corrosion by high-quality enamel. Additional corrosion protection is provided by a magnesium or an inert anode. The cylinder is well protected against heat loss by the polyurethane foam insulation that fully encapsulates it.
The compact boiler is available with a 15 or 25 kW output and a choice of three different cylinders.
DHW in the WAS Power 80 and WAS Power 115 cylinders is heated by a stainless-steel plate heat exchanger that is fed by a cylinder charging pump. This offers a high rate of transfer, and the low return temperature means that the boiler can also condense in DHW model. The compact boiler with the 80-litre cylinder is only 1570 mm tall, making it suitable for installation in areas with low clearance, such as a cellar or attic.
The WAS 100 cylinder transfers heat via a coiled tube heat exchanger within the cylinder. This well-proven method of heating can also be used where water hardness levels are very high.
