Pairing CO2 heat pumps with photovoltaic solar panels (solar hydronics) can give you the biggest savings.
As CO2 heat pump systems are totally electric, the greener the source of electricity – the greater the savings and environmental benefits. CO2 heat pump systems are ideal for integration with photovoltaic (PV) systems because plugging into a renewable green electricity source closes the loop – allowing you to go completely off the grid if you want!
A decent 5kW – 8kW PV system can actually give you CREDIT on your electricity bill, as you sell your excess power back to the grid. For even greater savings – existing rooftop solar hot water systems can be retro-integrated as a booster mechanism. Totally electric systems are now considered worldwide to be the most efficient.
Many users simply choose to source their power from a green energy supplier, to ensure they are supporting renewable energy resources. However, pairing CO2 heat pumps with photovoltaic solar panels combines to create an extremely energy efficient power source for your general household electricity use – solar hydronics!
