History Behind Heat Pump

The theory of heat extraction using gas was founded in 1805 by Oliver Evans, with the first domestic fridge appearing around 1890. Heat pump is derived from there and is similar to air conditioner. With such a vast history, air source heat pump technology is a proven and reliable concept for hot water application.

The following gives a brief overview of the development of this technology to the reliable and efficient heating systems that are built by established companies such as Lämpöässä today.

The first heat pump as we know it today was built by Peter von Rittinger in 1856. He recognised the principle of the heat pump while conducting experiments on the use of water vapour’s latent heat for the evaporation of salt brine. As a result, in Austria the heat pump was used to dry salt in salt marshes.

  • Today’s heat pump

    Today heat pumps are considered the most efficient and cost-effective heating in the market place. They are remarkably environmentally friendly, and they can drastically reduce your carbon footprint and energy bills. They offer an ideal way to heat your property and produce hot water whilst saving money and the earth’s precious resources.
