Octopus session 3, 8 points like the last 2 up to 24 points now worth 3p![]()
Nice!
Watcha gonna spend it on?

The £4k install cost is the above install cost of the ASHP and that is the figure we have just used on a contract for 350 home development. The developer has gone for that because for them they see it as a USP that adds value compared to that off the ASHP. The setup cost to get on site is shared between plots so the more plots you have the reletative per plot as drops similar to piling foundations where you have a setup cost and so if an extra say 10 plots need piling due to tree influence compared to the initial 40 assumed or whatever that cost isn't too bad and sub-divided can be accounted for.
The project planning for the pipeline we are finding is starting to be looked at planning stages and we are currently working with two larger housing developements that are aiming to be BIM co-ordinated for first pass with basically full foundation and structural design prior to even submitting to planning with hopes they are going to be able to expedite at later date (we don't generally agree it will work out that way but that is their aim on a few trial projects) andt these are larger multi block 800+ appartment site and mixed usage with solar and battery also being looked into.
All mixed use we have done design for last 12 months has got full solar on roof from framed sheds to appartments to carparks. I do also feel that house builders do need to consider their responsibility. It is the same issue they have for litereally paying customers off to get better NHBC ratings when you do the surveys by offering say free skip usage when you move in and want to landscape garden or dropping a load of bricks off to build a concervatory dwarf wall or BBQ area etc. They would rather that than build things to an acceptable level.
Somehow I managed 274pts even though I did nothing different and was away almost whole.7 days prior. Add the 100pts each session adds and might get to 1hr of heating in a month!Octopus session 3, 8 points like the last 2 up to 24 points now worth 3p![]()
What is the hacking and the pre session window thingy? I've got my session 3 results which are the same as session 1 at 1650 points. Session 2 was 2400 points and I've no idea what I did differently.Octopus session 3 seems to be in
Hacked mine, got 3224 points from combo of house battery reducing to zero and a sneaky bit of battery charging in the 3 hour pre session window.
I slightly overcooked the charge so added around 2kwh of battery I didn't need.
Following day I did similar so interested in saving session day 4 data where I didnt overcharge
My hands get like that too when at my desk.its been really cold in my home office today, 2 hot water bottles and a blanket but my hands are like blocks of ice.
So the £4000 additional cost by the house builder is added to the purchase price of the house. This on average is around 1.4% of the value of the property. With regards to that is a 12yr return to the initial cost. Now with regard to that then the longer you are at the property of course the better the return but it is also just good for future generations also.You said ASHP is a half measure and proposed GSHP as the alternative, so I’m wondering how you expect that to be feasible for the average newbuild and why that is the house builders responsibility to consider given its a large extra cost compared to the house price or a ASHP? Also how that initial large extra cost is worth the small efficiency gains for the average UK climate? I don't think you even get back the extra install costs of bored GSHP with lower running costs over a 20 year period even at current electric prices. eg if you take a heating/hot water use of 12,000kWh and assume a SCOP of 300% for ASHP, even if GSHP gave you 25% better SCOP performance at current prices the GSHP would save £330 a year, so over 20 years thats £6600.
Mike Foster, EUA chief executive, believes this new evidence renders UK heat decarbonisation plans “useless” and calls for a government re-set.
“The French have blown a hole in UK government policy,” Foster said in a statement. “Their experience shows that higher volumes of heat pump sales does not massively reduce their cost. The forecasted reductions, claimed by BEIS, are simply numbers plucked from thin air. Just across the channel we have real word experience, 537,000 heat pumps fitted last year, at a similar cost to that experienced in the UK, with our 50,000 sales.”
Foster added: “Heat pumps are a globally traded product, why would they be cheaper in the UK than France? It’s complete nonsense to suggest they would. Once you debunk this myth, the whole UK heat and buildings strategy falls apart. It now needs an urgent re-set.
“Boris Johnson set a target of 600,000 heat pumps by 2028; cost reductions of 25-50 percent by 2025; parity with a gas boiler by 2030. In doing so, he has thrown public money at subsidies, he has scrapped VAT on heat pumps, he threatens to fine boiler manufacturers if they fail to meet his targets. But his own advisory body have warned that heat pump running costs are higher than a gas boiler and now these mythical costs reductions are shown to be just that, a myth.
...
You can buy a heat pump in the local DIY store for 1500€ in France. The main problem is that you have to have a registered company fit it for you. This is where the companies rip off the governments & customers, instead of a reasonable cost; the same as insulation, solar panels etc.
A relevant piece of current information, hot from the press, is that the EU (and, by default the UK as co-signatories) are banning use of the fluid used in Heat Pumps as it is basically like CFCs and will damage the ozone layer. This means that other fluids, like propane will have to be used, a lot of new development is thus needed
Yeah there is no way right now that you can get parity on installation costs on a DIY system. But the argument given here isn't helpful. 5yrs od development and greater adoption will reduce the unit costs. These costs are the bigger part for house builders side not the installation when they are already on site doing ground works and such. Although this is mostly about ASHP too which as stated are completely different in that terms.maybe heat pump cost reductions aren't imminent https://www.theengineer.co.uk/content/news/evidence-for-heat-pump-price-drop-fails-to-add-up/

given forecasts of sub-zero - was wondering if the house thermostat has signed values.
£6 billion from Bulbs collapse is what 1.4million homes could have been built with a 50% subsidisation for that.
What is the hacking and the pre session window thingy? I've got my session 3 results which are the same as session 1 at 1650 points. Session 2 was 2400 points and I've no idea what I did differently.
Ah session 4 is also in now, 1600 more points
No I know. I'm just putting into perspective the waste that the gov did compared to what they could have done. There was no reason the situation should have ever cost £6 billion either.That logic doesn't work because it doesn't solve the bulb problem to subsidise green energy installations.
Also why would only some people benefit from this?
No I know. I'm just putting into perspective the waste that the gov did compared to what they could have done. There was no reason the situation should have ever cost £6 billion either.
And we are discussing new builds. Not subsidising current properties. Those costs are around 3x to 4x for retrofit compared to new build.
Pretty much your only option there is a straight electric boiler at the moment. That will 3x your running costs at current prices.I think everyone is missing 03/12, but it should pop back up at some point.
Oh I don't think many people would disagree with you, we are incredibly good at wasting money/resources.
What I'd really like is an air source heat pump tech that can almost directly replace a gas boiler location/size. ground source as you pointed out is very hard to add later on, much easier before you start putting people and foundations down.
ASHP is OK at least in so far as putting up an external unit outside, and an internal thing inside where the boiler goes, but they don't seem to be ready to replace boilers yet in function.
I have a wall mounted combi boiler, I don't have a hot water tank at all, so I would effectively need something that can do what the combi does, and can plug into the existing CH system and work with the current rads.
Off peak elec should be cheaper to use for heating (anything) than gas assuming your on go
Go 7.5p/8.25p vs gas 10.3p
Thats before you factor in efficiency of boiler and indirect inefficiency of the water loop and pump etc
