Heat Pumps: the Future of Home Heating

His whole channel (called Technology Connections) is probably my favorite one on YouTube, can’t recommend it enough! My favorites are his series on refrigeration and heat pumps, for example this one: [VIDEO] Edit: to clarify, this article is based on an old Technology Connections video, and the creator of that video has lots more!

Highly recommend the YouTube channel 'Technology Connections' videos on heat pumps: [VIDEO] [LINK] [LINK] [LINK]

> no wasted power Electric heating can be much more efficient than what's effectively resistive heating with 500%+ efficiencies being possible. Search for "heat pumps" or watch: [VIDEO]

> So the heat pumps can also do cooling during the summer? Here's a pair of really great videos about heat pumps and what they can (and could, in the future) do: [VIDEO] [LINK]

This video is a great explainer on heat pumps [1]. The TL;DR is that they are essentially nothing more than air conditioners that run in the opposite direction. Plus, a heat pump and an air conditioner can be combined into a single system. 1: [VIDEO]

> I'm wondering if there's any low-energy or green solutions to this. The answer is "it depends". How your flat is designed will have an impact on what you can do. But if you are able and willing to do some house work, there is a lot you can have control over. At the end of the day, it's all about how you can control humidity, the flow of hot and cold air and humidity. At your disposal, tools such as conductive materials, insulating materials, etc. Google "passive house" to see the concept and what these things use. With that said. Heat pumps are incredibly efficient, and replacing your heater with a reversible air conditioner which you can then run in both summer and winter will do far more for your overall energy efficiency than anything else you can do. Most of your energy consumption comes from winter-time heating. Start here for a good introduction to heat pumps and how they are so efficient: [VIDEO]

Our house is electrically heated via a heat pump, which has appreciably more efficiency than a resistance heater (or computer). Here's a neat video about them: [VIDEO]

There are highly efficient heat pump powered water heaters, going out anywhere remote, these and other heat pump systems should really be used. This is a really great overview [VIDEO]
