The build

Not a downer at all. The underground heating is used as background heat. We’ll be having secondary heatIng in living rooms & bedroom to boost as and when needed. Possibly inferred from  jigsaw solutions. Bob’s not 100% convinced. But he can shove the panel heaters he keeps rattling on about where the sun don’t shine   . As you can see not everything is written in stone already. 
Our first couple of house designs were done around us having a wood burning stove. But we scrapped it, when we realised that in 15/20 years time we’re not going to want and quite possibly be able to cut & split our own wood. Definitely can’t afford to buy in ready split. So we scraped it. Hence the ongoing discussions about heating.

The jury’s out with me on infrared heaters essentially they are indoor suns, heating objects rather than space. There’s obviously positive effects to some radiation the widening of capillaries, increased blood flow. I’m just unsure about the long term exposure, there’s some anecdotal evidence of them causing dehydration, headaches and dizziness, though I’m not sure there are any specific studies to this. I’m uncertain of the long term exposure of furniture to this type of heat source. Sun radiation causes bleaching over time and can cause moisture loss in all of things through evaporation. Will you need humidifiers to balance the equation, I don’t know.

I’ve never sat in a room heated with infrared heaters for any period of time so I have no personal experience of their effects but, they are certainly more cost effective than radiators. I’m just unsure whether they might effect guarantees on other items in your home. Wooden kitchen doors for example will not cope with direct radiation it will split.

interesting though, that’s an unusual combination of heating methods.
