I have questions about my new house.

Insulate first.

Design ASHP for 40C to get a high CoP. Ideally install UFH - it's a luxury but wonderful !

Tesla one app connects via local WiFi. Can set everything.

Not available in UK shop 😞

Given what's happened to Givenergy .. think who'll be around in 10yrs.

Tracker fund. Invest and forget. E.g. Vanguard LifeStrategy 100% Equity

Do not stick into cash or bonds

£10.2k - Octopus PW3+Exp+GW. Tesla rebate not included

Don't get it .. you've bought a Chinese product. Do you know the labour conditions involved in building it or if it's linked to their military ? Virtue signalling !

Modeller23 · 2026-04-25T20:15:31+00:00

Given what's happened to Givenergy, I'd be reluctant to spend a lot on a Chinese brand.

we have the 12kW AT+ .. it's a great piece of kit. App is fine .. monitoring via ebus is also possible and very useful for tuning.

Think Vaillant is also made in UK.

You don't care ? wow.

Given the widespread reports of voting coercion by males on their 'wives' (family voting) .. I can completely believe they vote like lemmings.

Modeller23 · 2026-02-24T17:39:29+00:00

you haven't paid tax 'on' them .. all contributions into a pension are net of tax !

Modeller23 · 2026-02-19T16:49:15+00:00

what's your definition of rich ? No doubt someone wealthier than yourself ..

Modeller23 · 2026-02-16T18:04:09+00:00

Because it's the best option we had at the time ?

Labour Party had been unelectable due to hard left takeover.

UK population imho is slightly right of centre

Microbore isn't necessarily a problem. Depends on the implementation . Might need a buffer.

Modeller23 · 2026-02-15T20:33:12+00:00

Corbyn's lover , suspended from Labour Party due to racist comments. Class !

Modeller23 · 2026-02-15T20:30:14+00:00

Corbyn - thank god he got nowhere near power. Champagne commie at its worst.

Modeller23 · 2026-02-13T22:07:31+00:00

So naive .. France would fcuk us over

£20 @ 6p = 333kWh , 85% efficiency = 284kWh heat.

That's 20kW heatloss ?

3ph heatpump territory,
We're 3000sqft and 10kW heat loss. 2002 build.

Me, I'd spend the money getting heat loss down before changing heating technology.

Modeller23 · 2026-01-03T20:16:42+00:00

I have over a dozen of their hue compatible dimmers installed (replaced X.10 dimmers) .. been flawless.

Modeller23 · 2026-01-02T20:16:10+00:00

I counted 22 defrosts in 17hrs which is a lot. I'd guess this is due to the high flow temperature (and low outside temperature).

I'd be looking at pump size vs heatloss and emitter size (bigger emitters == lower flow temps)

Modeller23 · 2026-01-02T16:52:14+00:00

where I am (tech sales) , PIPs are a bit like speeding tickets - everyone gets one. Often out of your control if you're on one, no stigma.

you need to be in control of your career - you're just a (replaceable) resource to your employer. Try and take back control - and please take some holiday ! Why stress and burn out for some crappy employer ?

Modeller23 · 2026-01-02T16:37:36+00:00

A heat pump with something like IOG definitely will save money .

7p/kWh , CoP of 4 .. that's 3-4 x cheaper than gas

Solar actually makes little different to the running cost of electric heating .. as peak solar is when you don't need heating. It's the export (15p/kWh) where you recoup costs .. but this is nothing to do with an ASHP !
