New air to water heat pumps from STIEBEL ELTRON
to overview| If there was no space heating available in existing buildings as a heat distribution system, this frequently used to pose a problem when installing heat pumps. Flow temperatures of over 60 degrees, which are needed in some of these older buildings, would make the use of environmentally friendly heat pump technology for heating impossible without additional measures. STIEBEL ELTRON now offers the ideal appliance for use in instances like this too with the new high-performance WPL 14 HT heat pump: flow temperatures of up to 75 degrees and a high heating capacity of 12.5 kW at an outside temperature of -15° make it possible to have monovalent heating without additional electric heating. In this way a combination with practically any system for heat distribution, in particular radiators as well, is feasible. The technical risk for the engineer in refurbishments with heat pumps is kept to a minimum and the customer has no need to worry about excessive electricity bills as a result of direct electrical heating. Two compressors, each working with innovative inverter technology, perform their job on the inside of the heat pump and ensure the high flow temperatures and unique performance characteristics. This principle is hitherto unrivalled in heat pump technology and thus sets new standards. In conjunction with domestic hot water heaters from STIEBEL ELTRON it is even possible to achieve domestic hot water temperatures of over 60 degrees without any difficulty. Thanks to the electronic expansion valves the COP has been optimised throughout the entire range of applications. As a result of the inverter technology the thermal output of the heat pump is adjusted for the heat required in the building, so that optimum operation is guaranteed at all times. In addition, the integral special-purpose cylinder permits operation without an additional buffer cylinder. The high-performance heat pump, available for indoor installation only, can stand apart from the rest, not only because of its technical specifications but also on account of an award-winning design. It has been honoured with the renowned iF 2009 product design award as well as the “Observeur du Design 2009” – one of the most prestigious design awards in France. |
