Heat pump
-
Energy from the air, ground or groundwater
Heat pumps use energy from air, underground or groundwater for domestic hot water, cooling and central heating.
Benefits
- Compliant with the new South African Government requirements for heating
- 50 to 80 percent reduction in heating costs depending on model of heat pump
- Economical even at outside temperatures of -20°C
- No CO2 emissions ("zero emission heating" when using green electricity)

How a heat pump works
The heat pump is a thermodynamic heating system. It can be used to convert environmental energy into heat for your home. The heat, which is drawn from water, the ground, outdoor air or air extracted from the house, first passes through an evaporator from whence it is fed, via a condenser, into the heating system.
Approximately five parts environmental energy and one part electrical energy is provided as heating energy. Electrical energy is required to "pump" the environmental energy, which is at a low level of -20 °C to +35 °C (air), to a temperature level suitable for heating domestic hot water.Energy Label for heating heat pumps
The top of the ErP label displays the name of the manufacturer (I) and the model designation (II) of the product. The rating system for heating heat pumps categorises them into nine efficiency classes. A++ is the highest energy efficiency class. G denotes appliances with extremely poor heating values.
STIEBEL ELTRON products are almost exclusively in the top group. All STIEBEL ELTRON heating heat pumps are already in the top rating category, i.e. classes A to A++.

The right heat pump
The WPL 15 ACS
Positioned and installed outdoors, the WPL 15 ACS air|water heat pump can be used for heating in winter and cooling in summer. The WPL 15 ACS is the right option, even in very densely built-up areas, as its low operating noise will not disturb the neighbours. The WPL 15 ACS is designed for outdoor use. The appliance carries an A++ EU Energy Label and offers cosy warmth from the air, while others turn on their central heating.The air|water heat pump can also be used at temperatures well below freezing point – and is always exceptionally efficient. These heat pumps can also be used in modernisation projects due to their high flow temperatures that are achieved even at low outside temperatures.

Domestic hot water heating with heat pumps
You need an affordable solution for your domestic hot water: for domestic hot water heating from renewable sources, the domestic hot water heat pump offers a quick and convenient solution. Domestic hot water heat pumps are affordable to buy and easy to install. They are outstandingly efficient, as the heat is recovered from the ambient air at the installation site.
* Certain parameters are assumed when issuing quotations. Your qualified contractor will have to confirm and evaluate these in person during an on-site visit. If an alternative solution needs to be found due to the installation location or other factors, the quotation may need to be amended.
