Saving energy with air and water: STULZ presents the new WPX2 air-water heat pump from Mitsubishi Heavy Industries

In the area of alternative heating systems, STULZ will be presenting the new WPX2 air-water heat pump system from Mitsubishi Heavy Industries at this year's Chillventa. Two models with differing output levels can now be used in residential buildings and offices.

Hamburg, October 2010. At Chillventa 2010, the German air-conditioning expert STULZ will be presenting products such as the new WPX2 system. The air-water heat pump from Mitsubishi Heavy Industries consists of an inverter-controlled outdoor unit, a water module placed inside the building and, depending on the model, an integrated or external buffer storage. In collaboration with the air-conditioning experts at Mitsubishi Heavy Industries, STULZ has gained over 35 years of experience in the area of heat pump technology.

In comparison to other heat pump systems, an air-water split system is quick and easy to install. Investment costs are also kept low. Both the indoor and outdoor units require a minimum of storage space. And in contrast to other heating systems, these units require neither a chimney nor an oil tank. Which means that by installing an air-water heat pump, end users are both protecting the environment and saving money.

Different output levels for different requirements
There are two models available for this system, each with a different nominal heating capacity. This means that the WPX2 heat pumps are ideally used in the heating of both single- and multi-occupied houses. The smaller version has a nominal heating capacity of 9 kW, while the larger WPX2 unit is 16.5 kW. For pure compressor operation, a maximum flow temperature of 58 degrees is possible; a maximum of 65 degrees in combination with the integrated electrical supplementary heating system. There is also a cooling setting possible for the summer months which involves, for example, feeding cold water to the fan coils or a cooling ceiling. And priority switching ensures that there is always enough hot water for the bathroom or kitchen regardless of how it is used.

Both WPX2 systems have an integrated time-controlled system for an optimal supply of process water and for raising or lowering the flow temperature. Thus saving the end user both energy and operating costs. A comprehensive selection of accessories, such as a room remote controller, is also available from STULZ.
