Why radiators are the future of cooling


Experts call this the “cold crisis”. As temperatures rise in regions that historically have not required indoor cooling, global demand for air conditioning units is expected to skyrocket. Indoor cooling is already the fastest growing energy use in buildings. But the emissions associated with cooling buildings are tiny compared to those of heating buildings – and that’s because our heat is still largely generated by burning fossil fuels while air conditioning uses electricity.

The way we heat our homes and buildings is one of the biggest contributors to climate change. But a solution may actually come from the scramble of consumers looking to buy AC power for the first time. There is a huge market for another type of system: the electric heat pump. A heat pump works like a two-way air conditioner, using electricity and a chemical refrigerant to transfer heat to or out of a building. Instead of using fossil fuels to generate heat, it uses electricity to transfer heat, and it does so efficiently. And if heat pumps are widely adopted, they could have a major impact on the carbon emissions generated by buildings.
