Heat Pump Technology

Heat pumps aren’t new technology, they’ve been around for decades now and have been put to a variety of uses throughout the world, with refrigerators and air conditioners being some of the most common examples.


Heat pumps, at their most basic level, extract heat from one place and transfer it to another. This is the simplest possible explanation, but there’s a lot more to it than that. Heat pumps transfer heat by circulating refrigerant through a constant cycle of condensation and evaporation. 

A compressor is used to pump the refrigerant through a pair of heat exchange coils, each of which is used in a different part of the cycle. In one, the refrigerant is evaporated at a low pressure, which causes it to absorb heat from its surroundings, it is then re-compressed on its way to the other coil, where it condenses at a high pressure. This process results in heat being brought in from the surroundings, then passed on through from the coils into the water tank they wrap around (in the case of water heat pumps).

Heat pumps are reversible, hence their usage both in heating water and in running your air conditioner to keep your home cool in summer.

The iStore smart hot water system is a fantastic example of heat pump technology, but it’s so much more than just a heat pump. The iStore system combines heat pump technology with fantastic efficiency, and solar PV system compatibility to provide your home with some of the cheapest, most efficient and most readily available hot water on the market today. Regardless of the temperature outside, the iStore will continue to work at peak efficiency all day and all night, interested?
