In this work, the environmental performance of a condensing boiler, an air source gas-driven absorption heat pump, and an air source electric-driven heat pump for residential space heating and domestic hot water were compared through the consequential life cycle approach. Two scenarios were considere...
It’s almost always possible to rely entirely on a heat pump, but sometimes it’s more practical to keep another heater. For the rest of this guide, we'll be focusing primarily on air-to-air heat pumps. What are the best heat pumps? Don’t get too fixated on this. It helps to ...
This is the fifth winter since I’ve been heating my house with a Mitsubishi* heat pump. And finally I got to see something I’ve missed every time it happened until last week. Yep. I’m talking about seeing frost on the outdoor unit of my heat pump. So I ran for my phone and ...
The feasibility of using a dual heating system for Swiss buildings was studied. This system includes a heat pump operating alone when outside temperatures are above 0 exp 0 C and operating simultaneously with an oil burning system during low temperature periods. A house was retrofitted with the ...
