This impressive design has a certain operation selection down to -twenty five°C ambient temperature, even though utilising the refrigerant Houses of R290 to successfully reach large water temperatures approximately 75°C plus a very low GWP (Worldwide Warming Probable). Applying electrical power, the pump compresses the liquid to enhance its temperature. https://purethermal.co.uk/media-news/q4-launch-lithium-large-capacity-r290-ashp-from-pure-thermal-and-enerblue/
