Say Goodbye to Gas! Heat Pump Installation Experience with Octopus Energy Part 1 

love to hear how it goes plus any tips you have afterwards. i’m also on a fit for 2kw of my array, in the process of trying to get it approved as 1/5 of my total as an upgrade.

Thanks for the sub! i’m hoping i have my maths right and the solar/batteries will power the heat pump for about 9 months of the year, stay tuned to find out if i can’t add up :-)

Have you tried British Gas, my friend had similar experience, BG said no problems and installed one

my first thing would be, what evidence do you have to say “they will come” and you may be able to power your boiler with a jackery but if power outages are on that scale what’s powering the local gas pumping station ?

and if there are power cuts in the next couple of years it’s far more likely to be from the energy policies of the last government, you know who had over a decade to fix it

@@JonathanTracey actually all governments are useless at planning ahead for energy

now that we can agree on, i’m hoping to see the new one at least do something about standing charges. they go up multiple times a year even if rates go down. it’s a tax because you can’t avoid it

How much did that cost you?

Do you have enough capacity to run it from stored energy, I’m hoping that most of the usage will come from battery stored energy, only pulling from grid in extreme cold days ?

​@JonathanTracey originally I had a 9.5kw battery with solar..i doubled up for winter specifically for the ashp when it got installed - working off the basis that for 6 in 24 hours I will be charging and heating simultaneously at 7p per kw on IOG EV tariff. 11.30pm-5.30am. So far so good. Currently have 50-60% by time of recharge slot and heatings been on recently. I do anticipate there will be cold snaps that may burn off all 19kw but hoping these will be the exception. So I'm building up a surplus credit to cover this possibility. 20kw or so storage seems to be a sweet spot for storage for ashp.

​​@@kloddi25the 6kw solar array plus original 9.5kw battery was 11k. Bought 2.5 years ago. I got a loan specifically for this bit with term matching projected payback time of 5 years. Currently on schedule to be paid off in 2.5 more years. Half paid off already with current/previous energy prices. So pleased with that. Battery has 12 year warranty. ASHP cost me about 2k after grant, but as I have a barclays mortgage they also gave me an energy grant of 2k on top of government 7.5k grant. Octopus also knocked off a further £200 as Daikin were doing a deal which Octopus passed on to customers.. So I got the ashp free basically. I then bought a second 9.5 battery for 3k for the winter months of using ASHP.. so the total install cost to me for everything (Solar, 19.5kw of Batteries, inverters and ASHP) was £14k.

That’s encouraging, I’m on agile right now but will switch to IOG for winter. Were heavy users so have nearly 40kwh of batteries and was considering more but may hold on and see how this winter goes

so i took out the extended warranty and it gets serviced every year for 5 years. so no more expensive than my 27 year old obsolete boiler

Thanks for the tip, it’s included but it does not specify a location so will make sure it’s not in direct sun. Did you zone the house or just go with one zone?

@@JonathanTracey Single zone.

That’s what I have been told is best, tbh that’s what we have now

Agreed. External sensor north facing in shade. Had to ask my engineers to fit it as they nearly forgot... relying on internal one on ASHP isn't sufficient. They were nice sbout it though. Wasnt an issue.

Do you want it in the most shaded spot or just north facing

look forward to meeting in person

this is the code they gave me 24607664613 apparently all you have to do is give it to your specialist before you sign the contract. thanks for trying
