@dajb we had one fitted two years ago, also by Octopus. The standard of work was superb.
As expected, by itself it doesn't save us much financially compared to gas heating but it's using one third of the energy, which is pleasing.

@dajb@social.coop@slothrop@chaos.social That’s really cool, I hope to have this setup in a few years. It feels wrong to be dependent on gas in this day and age.
On the resilience from home batteries and solar though, watch out. Most systems will turn off in the event of a power cut. It’s something about avoiding back-feeding to the grid. If you want this you need to specifically get a system with an “emergency mode” or something like that.

@sam it's specifically the synchronization on the grid frequency. Your system needs to support "island mode". There are many that do.
On the autonomy aspect - do the math first. In our latitudes producing enough energy November - February means having a LOT of panel area. Especially if you plan to heat electrically.

@dajb hell yeah, that's awesome

Congratulations on the new heat pump! A colleague of mine had #Octopus install one for her earlier this year, and she's delighted with it. We went with #GoodEnergy because Octopus wasn't able to help us, but I'm convinced Octopus would've been better value if our house had been suitable.
We're not yet ready to buy a battery — I want to go through a winter with the new heat pumps so that I know how much capacity to buy — but I've heard good things about #Victron. You might give them a look. They seem to be a bit more expensive than canned systems like #Powerwall, but a lot more flexible.
@dajb @sam @slothrop Would love to have a heat pump but our property couldn’t accomodate one. And there are plenty of good alternatives to Tesla, in fact Octopus has their own preferred one. But yes the real rub for us is retrofiting the off-grid capability. My recent calculations had us breaking even at year 10-12, the natural lifecycle of the battery.
