Even as energy prices are soaring, there is still one heat source that offers cheap, reliable, and green energy. And the best part, it is currently unutilized for almost all restaurants, hotels & schools in the UK.

"The Swedish Chamber of Commerce hosted a dinner and I was suddenly sitting opposite Enjay co-founder Nils, talking about business. I was so excited about their patent that I told him this was a game changer for heat recovery," says Stefan J. Herde, head of international business development at the leading German engineering company Emutec GMBH.

How come a restaurant in Kiruna only pays 50% of the cost that a restaurant in Birmingham pays for heating, even though the indoor temperature and the cost per kWh is the same?

Elda för kråkorna, “Light a fire for the crows” is a Swedish expression for when someone is wasting energy or heat. And, that saying really expresses what is going on in restaurants all over the UK right now where warm air is ventilated out from the kitchen and instead electricity is used to raise the temperature of the cold supply air.
