Profile: Home Smart Energy specializes in providing thermodynamic hot water system, central heating management system, foam loft insulation, and solar PV with battery storage options. It can be best described as ?A Fridge in reverse?. Most people understand that the panel on the back of their fridge is a factor in keeping its contents cold. Reversing this principle by using an aluminium collector (panel) to absorb heat rather than reject heat, allows us to utilize the ambient air temperature, day and night in all weather conditions to change the refrigerant liquid circulating through the panel from a liquid to a gas form.
