wind turbine, solar export & ditching gas for ASHP.
On October 26th 2023, I had an Air source heat pump commissioned in my 95m2 1960’s three-bedroom semi-detached house in Flintshire, North Wales, replacing a mains gas central heating combi-boiler. The building has cavity wall insulation & A-rated double glazing. 🧵
The Gas meter was removed on 3rd November. With no standing charge for gas, solar, battery storage,

You're very welcome, and that's exactly why I post these things. The negatives you hear are not backed-up by reality or are the result of poor installation.
This chart shows how much less energy the heat pump uses compared to gas to deliver more heat. Ten yr av. gas use in November was 726 kWh, 653 kWh of heat at 90% efficiency. The ASHP used 308 kWh of electrical energy delivering 924 kWh of heat, assuming a conservative SCOP of 3.
We don’t see this too often in the UK, solar generation sitting at the top. Something tells me another record might go today, the current max solar is 10148 MW. This will be beaten at around midday if the temperature doesn’t get too high.
The system design was tested in early December, with outside temps reaching -3.5C. The weather comp. increased flow temp. & radiator output, maintaining the internal temp. set at 19C. Thermal comfort has improved considerably, & the water cylinder is also heated twice/day.
As all the radiators were undersized, some pipework needed relocating & was mostly microbore, & a hot water cylinder was required, we decided to renew the whole system with 22mm & 15mm copper pipework and new radiators to optimise efficiency and futureproof.
I calculated the heat demand using dimensions and U-values of construction materials, and an air change rate of 1.5 Ach/hour. This gave a building heat demand of 3.9 kW at a design temp. of -3 external & 21 internal. The house is EPC-rated B.
The installer

survey suggested a 6 kW ASHP. After discussion, using my 10-year gas demand data & degree days data, we concluded this could be reduced to 5 kW and still be slightly oversized for extreme cold events.

Yes it does, & an ASHP must supply both heating & hot water to receive the £7.5k gov grant. It doesn't mean you can't have one, you just need a big tank & HP will heat it for when you need it. You won't run out if you manage it properly.

The last 24 hours, house almost completely powered by battery and solar except for 1 kWh from the grid to power the electric shower (blue spike). Two loads of washing done, house powered & battery fully recharged by solar during today. Battery powering house last evening and now.
Wow! The last 30 days has been awesome for solar. My 2.8 kWp system has powered my home, charged the house battery and charged the EV. The blue bars are the only two car charges from the grid. Those aside, I've only used 13 kWh from the grid for my home.

Logging my energy data this morning & thought I'd do a little analysis on solar generation. Over nine years, nice to see the system is showing no degradation. Although there appears to be a trend towards increasing spring solar & declining summer solar irradiance (blue line).
I love this graphic on my

@Telegraph
there won’t be a ‘waste battery mountain.’ The batteries will last at least 10 years in the car, another 10 in home battery systems and then 100% of the valuable elements will be recycled into new batteries.
Considering nothing else but grid electricity in my local area, my home is being heated and powered by 98% zero carbon sources right now. Just saying.

We’re not relying on imports, rather choosing to use their low-carbon, low-cost generation to reduce our gas generation, emissions and cost. It’s a connected system which works both ways, collaboration which actually builds resilience.

I'm going to make this a heat pump install thread to document the progress of the installation. First up, the base has been installed today. What was once a bed of bedraggled bushes/flowers which has been transformed into a sturdy base with drainage for the condensate. 1/2
My updated Household CO2 emissions data for 2021. There's a slight increase in total CO2 of 0.2 tons shown in the fingerprint due to car travel returning to normal levels & an increase in carbon intensity of grid electricity compared to 2020 levels.

I think what you're doing in the UK for EV charging is awesome. BUT, today you caused me a problem. Three of five chargers on my route in North Wales were down, Two were in use. I lost an hour on my journey trying to connect to then waiting to charge
One of the benefits of a green roof is that it insulates against extreme heat. These images show the internal & external temps. right now with the sun directly on the roof. I’m sure my neighbours internal temp is much higher without any protection.

Yes, they added some more solar and fitted a new EV charger for me last year. I think they sub-out the cavity wall insulation now though. Give them a call, I'd recommend them for the things they've done for me.

Based on receiving £30 per month 8.33 years. The wind farm will generate for 25 years+. So I've bought at least 25 years of cheap electricity for the price of 8.3 years. However, I don't concern myself with payback times, I do this to get stuff done, doing nothing gets us nowhere

Great thread Glyn! I have monitoring & display envy! 😂 You will now spend the year working out different regimes through the seasons to find what works best for your situation & the grid. The flexibility of a battery gives the consumer complete control of their power use. Nice!

Another day of sun, charging the EV from solar only. Over the last four days I have put over 100 miles of charge into the Hyundai Kona EV in this way, no cost, no carbon emissions, no pollution, no grid use.

I’m guessing this is yet another comparison which has completely ignored the colossal carbon emissions produced by oil extraction, transportation, refinement and storage for petrol and diesel. Ev’s are even greener than this suggests.

Is that the race of the past where animals are run to the point of exhaustion and some die for so called human entertainment? By ‘the past’ I mean when people didn’t know better, similar to grouse shooting & fox hunting for fun. We are in the 21st century not the 19th!
Furthermore, broken, old, badly maintained chargers only serve to fuel an anti-EV narrative that needs no help. By not upgrading these chargers you are complicit in stalling EV adoption. I hope you're listening
@toddington_h
The EV community in North Wales deserve an explanation as to why you have not upgraded the chargers on the A55 expressway. There needs to be more chargers at these sites too. You have been asked this often, please explain why you have neglected this region, it's not acceptable

this juvenile Robin has learned to follow my robot lawn mower as it disturbs invertebrates in the grass. In fact, all the robins in my garden do this. The mower is almost silent, autonomous & charged by solar power.
Trying a different regime this summer to make better use of exported solar power. My rooftop array is SE facing, so I am now turning off the battery in the early morning so my excess solar powers my neighbours as they start their day.
My updated Household CO2 emissions data for 2020. There is a slight reduction in total CO2 of 0.2 tons shown in the fingerprint due to less car travel during lockdown 1. Personally controllable emissions at home = 1ton/year, a 76% reduction from my 1998 baseline year.
