In the video the guy uses what hey calls "hyper loops" to me they just look like those cheap solar pool heaters. That looks much easier to handle and I'm assuming it's much more surface area compared to just a few hundred feet of pipe thrown in the cistern.
I guess if the WMO boiler works like I hope it will, I'll be able to just hear the house directly off off the water from it. Then maybe between the heat pump and the fireplace(with and insert) I will be able to heat the house pretty easily. But we will see how this project comes along this winter. This summer will be full of moving and a diy wedding in our new back yard
