I say listening, more like singing tunefully and dancing elegantly..(in my head) makes it difficult to do more kitchen electrics..

Yes, I get that, but the hot water doesn’t heat the house right? I assume it is a very well insulated house? My house of equivalent size needs 12kw to heat it in the deep midwinter for example.

On a fundamental level 0.8 kW isn’t equivalent to the 12 kW or more from a boiler or ASHP. On a certain level heating / cooling is a simple equation, you have to put in more than you lose, so for this to work, something else must be different.

we use 1 unit to heat the water tank and 2 units to heat a 500lt thermal store and the heating zones
or a buffer tank on the heating the unit run continues from the pv and battery
same as ASHP but without the runing cost of a ASHP

I've 300 miles to do on Monday, and 100 miles tomorrow.
I've had to syphon out the Maserati life blood to fill up the Beemer and Pinini.
Fortunately the Maser was full so plenty to go around with a few spare emergency cans too!
Crazy situation.

Great, I’m getting it now.

The Bunsen unit is what we in the trade call a split heat pump system. It has all of the same components and works in the same way as an ASHP.

Input power is 0.4 kW, with max output of 2.6kW. It is subject to all of the concerns outlined about unitary ASHPs I mentioned above but with the added issue that it uses R134a, the same as our cars, with a GWP of 1430 (I.e. it’s 1430 times worse than CO2 as a greenhouse gas when it gets out) and it will be banned in Europe next year. They may well have changed this since they published the brochure.

At least with up to 5ish kW it stands a fighting chance of heating a home, but I still think the property it’s used on would need to be very well insulated by current standards. I assume it’s a new build?

Understood, so as a retrofit option, it’s difficult to recommend it as the system output won’t be enough for older housing stock. It’s not really in competition with ASHP retrofits. A very interesting solution though.

I've realised over the years, to be a successful businessman/woman you need to be an underhand ruthless immoral crook, a bit like a politician, try to do things by the book and you'll never make it. I Don my hat.

There was a TV program years ago where teams had to do certain tasks, a team of engineers, another team(can't remember what trade) and a team of CEOs/entrepreneurs. They were each given the same task. The engineers looked at the request and set about it logically. The entrepreneur team just questioned the rules and then looked how to push those boundaries to achieve the task.
Maybe we're missing something.

That would have been June of what year? We were on LM at the same time complete with a 20L can in the back.

Filled up the Fiat yesterday, no problem at all. It had 25 miles left in it. Fifty quid of super (shorter queue!) should do us for another 6-8 weeks. We might burn wood at times through the winter, but we don't get through much petrol.
