Everything you ever wanted to know about heat pumps

The environment is full of energy. Solar energy is stored in the air, in water or underground and a heat pump allows you to use a large part of this as heating energy or for DHW heating – as illustrated here with an air/water heat pump installed in the ga (PresseBox) (Holzminden, ) “Energy prices are turning the heating market upside down”, “From insider tip to problem solver”, “Anger over high oil and gas prices” and “Why is a heat pump the right choice?”: In these days of permanently high energy prices, many homeowners are searching for alternatives to oil and gas. As the headlines show, everyone is talking about heat pumps and demand is huge. But what actually is a heat pump? What can it do? What does it have that other systems don’t have? The environment is full of energy. Solar energy is stored in the air, in water or underground and a heat pump allows you to use a large part of this as heating energy or for DHW heating. Such a system always makes economic sense. Heat recovery works even when outside temperatures reach –20 degrees. Projected over the year, a heat pump generally reduces heating costs by around 50 % compared with conventional heating. With such potential savings, a system’s investment costs can be recovered in just a few years.
Engineers in Germany have been working on the heat pump for the past thirty years. Back then, STIEBEL ELTRON started to develop units that would use renewables. So not only has the company been one of the pioneers, but it continues to blaze a trail today for new developments. Progress is particularly evident in the units’ efficiency. Today’s heat pumps outperform the earlier models several times over.
Compact heating systems have since been added to the classic heat pump systems, using environmental energy to provide central heating, hot water, cooling and ventilation. They are simple to install and offer total convenience. In terms of service life, heat pumps are comparable with any other heating system. Many systems have been in constant operation for more than 25 years without a problem – in fact they have been extremely reliable and have required practically no maintenance.
Heat pumps are recommended for use in conjunction with low temperature or underfloor heating systems. But even with radiators and flow temperatures of up to 55 degrees, there is still a convincing argument for heat pumps in terms of heating costs and environmental pollution.
Heat pumps designed to use the energy from the earth or from water are always installed in the cellar or utility room. If you wish to heat your house with outside air, the option is available to install the heat pump outdoors (in the garden for example) or in the cellar.
Heat pumps are increasingly coming to the fore not just in new buildings, but as part of modernisation work too. So these highly efficient systems can be used to replace an existing gas or oil boiler. Often it is possible to continue using the existing heat distribution system without any modifications, particularly if the building's heat demand has been reduced over the years through additional heat insulation measures.
