Why we need "Net zero"

Exactly the same a solar assist heat pump outdoor condenser, but indoors 

Ha! Yeah, but prettier obviously. 

 

What is that product? I wonder if you could get around the big box of an outdoor unit with a large black roof/wall mounted panel

Dont think id want them in my house though.

 

 

Cheap but noisy, and easy to fit,  but  just for one room. But buy in southern Spain (prob france too) and they are much cheaper...and noisier.

If that was running off solar and battery that shouldn't take long to pay back.

Came very close to fitting 2 in my office and "clean room" in my workshop. Well, the propane filled ones, so no need the an F gas person.

 

Sadly, my "electricity supply" issue means that ill need to go oil for that too. Lots of second hand boilers around at the moment for bugger all money. And easy to DIY.

 

Which is a shame, because this would have been much simpler.

My air to air system doesn't look like that. 

There's a normal outdoor unit like any other ASHP.

Then under the floor there's the indoor unit, completely out of sight. Insulated 200mm ducts go from this too each room (smaller rooms split down to 150mm).

The warm air comes out of wall grilles. One in the kitchen plinth, the others are just above skirting level.

Each grille has adjustable vanes and a damper to restrict the flow. I've throttled down the kitchen one a little but otherwise haven't touched these. 

 

The house is 93m², the ASHP is 10kw, which I thought might be slightly oversized but it's what the installer suggested.

 

In use, we tend to set it to anywhere between 18-20⁰C. The thermostat is in the hallway in the middle of the house. You can close doors on individual rooms if you want them hotter. So usually we leave bedroom doors open and that keeps those rooms comfortably cool, while closing the living room door lets the temperature go up to a degree or two more in the. We could adjust the dampers to achieve the same thing but opening and closing doors is easier!

 

We do light the woodburner in the evenings so when I say we're spending £1-£2 a day, it's not quite the whole story. I reckon we maybe save £1 a day lighting the stove. Which does make me question the wisdom of spending so much time and effort chopping logs 😂

 

Edit to add: total installed cost was about £4200 including every little jubilee clip and clamp. Most of that was the supply and fit of the indoor and outdoor units. I ran all the ducting myself. A simple but time consuming job that the installer wasn't interested in taking on himself. I likely saved a lot of money by doing that myself. 

 

And just to reiterate, zero grant funding towards any of this.
