The 'infection' has spread to here ... Jetski's

We use ducted air with air to air heat pump in our little house. It can cope on its and maintain temperature inside at 23C when it is -10C outside.
We tested that one day last winter. Temperatures here are usually in the range +5C to 38C winter low/summer high.

In the main building on our site (about 3000 sq ft) which we will use for offices, we have 3 such units installed - and they are a bit bigger than the one for our house.

You just install enough of them to cover your heat losses at the desired ambient temperature.

We love our ducted A2A system. I can press a button on the app when I'm ten minutes from home, and arrive to a lovely toasty house.
The wood burning stove has been relegated to a novelty now.

Our 8kw burner is important secondary heating. Apps for heating control aren’t limited to heat pump systems. We have that too. But I’d need a very great deal more than 10 mins if the house has actually been allowed to cool down.

This is where a blown air system is great. It's a bit like having a giant Eberspacher for your house, but with a much larger volume of slower and cooler air.
