Heat PumpsWe supply and install leading brand name heat pump systems such as ITS, Alliance and Carrier.
There are two main types of heat pumps – air to water heat pumps, and water to water heat pumps. You would use an air to water heat pump to heat your geyser water, radiator water, underfloor heating water, or swimming pool water. These use energy that is always present in the air to heat water by drawing the air into the pump and converting it to usable energy. A water to water heat pump uses energy always present in water (such as borehole water) to heat water.
- Single phase heat pumps from 3kW to 5kW
- 3 phase heat pumps up to 100kW
- All heat pumps can be paralleled for larger outputs
- High efficiency with 4:1 COP
- Easy installation and maintenance with existing geysers
- Integrated geyser versions available (heat pump and geyser in one unit) – ideal for new homes/no existing geyser
Why are heat pumps so effective and how do they work?When you think about cooling a hot building, you probably don’t think of heat pumps. In fact, the phrase “air conditioner” is likely to be the first thing that comes to mind. As it turns out, a heat pump can both heat and cool, and in some applications, it’s preferred in place of separate heating and cooling systems.
Simply put, a heat pump is a device that uses a small amount of energy to move heat from one location to another. Heat pumps are typically used to pull heat out of the air or ground to heat a home or building, but they can be reversed to cool a building, so there is no need to install separate systems to heat and cool. Heat pumps also work extremely efficiently, because they simply transfer heat. They work best in moderate climates, so if you don’t experience extreme heat and cold in your neck of the woods, then try using a heat pump and save money on your electricity bill.
Solar energy that can be used to heat your home is stored in the bedrock, ground, air and water. A heat pump utilises this inexhaustible and eco-friendly source of heating and transports it into your home or building. The type of heat pump you need depends on where you fetch the stored energy from.
Air to water heat pumps – how do they work with a geyser?Heat pumps generate hot water far more efficiently than conventional geyser elements, and current COP ratings are around 4:1. This means that for every 1 kW of energy that is consumed, 4 kW of energy is generated. We can supply a complete heat pump integration kit for connecting a heat pump to an existing geyser.
Advantages of heat pumps:
- Easy installation. The installation of a heat pump doesn’t require intricate plumbing work and is fairly easy to install, on both a commercial and residential level.
- Minimum space requirements. A heat pump does not need to be installed on a roof, and can be installed outdoors.
- Hot water 24/7. Because a heat pump relies on electricity, it can provide hot water 24/7 when there is dependable electricity supply.
- Savings. Heat pumps can save up to 75% of energy required to heat water – this translates into a 30-50% saving on a household’s electricity costs.
