On a pro-rata basis it is similar. I do just have resistance heating and I cook on electric. You could get loads of PV on your roof, and at different angles. This time of year you could rent your drive out for EV charging at 25p/kWh. For a real laugh, you could convert your kit car to an EV. Two advantages of that, it would cost nothing to run, and it would run.

They can, as happened to me, try and take £2500 out of your account, then a day later, £1999, and then 2 days later £999. All because the meter was read incorrectly. Cost me £90 in bank charges. I know if you keep an eye on it you can correct it at the time, but I was away. So now I just submit my quarterly reading and pay the adjusted bill. Just payed it, but had to take 80 kWh off the estimated Day rate and 61 kWh off the Night rate. That 'saved' about 40 quid, or £12.50 a month. Edit: Just remembered that I added a bit on when the price change happened, so probably quite accurate on the Night rate, but way over on the day rate.

I use kWh/day, or kWh.day-1, or MJ.d-1. First week of this month has been a total of 22.4 kWh, Day usage is 4.9 kWh and Night usage is 17.5 kWh. So for just me, that is 3.2 kWh.day-1, So similar to your usage. 78% of it is at the Night rate.

Sounds like it is only using the inbuilt immersion heater to do the work. Don't boost, it does not work like a gas boiler. Maybe you should raise the temperature up to 45°C and just let the ASHP top it up as needed.

2 bathfulls then.

I think I heard that they are openly doing this to reduce the 'shock' of the next rise. This may be a reasonable thing to do for the great unwashed, but for those of us that keep tabs on it all, it seems a bit cheeky. It is the standing charge increase that pisses me off, part of the increase is to cover bad debt. Others debt in other words. Can't see why I should pay for my junky neighbour to have power for nothing. What happens if your bill, for a year, is less than 400 quid?

I think the big financial advantage of E7 has now gone. EDF are charging me 33.33p/kWh Day Rate, 17.68p/kWh Night Rate and 55.1p/Day meter rental. Just looked at my meter, was changed in 2006, and I have used 28% on day rate and 71% on night rate. This works out as a unit cost, at todays prices, of 22.06p/kWh. Last year I had changed that fraction to 17% and 83%, so 20.34p/kWh at todays rates. So on reflection, by being very careful, it is still possible to get a decent overall rate on E7.

No. If YOU remember.

Just had a look at my bills as a comparison. Last year for March, April and May 2021, 1047 kWh This year, 2022, 723 kWh. So a saving of 324 kWh, 25%. I am currently only heating the top of my water cylinder on the E7, but too early to know what difference that is making. Now every month I have been away for 4 full days, but as I leave early on the Sunday and come back on the Monday evening, there will not be more than 10 kWh/month difference.

Reliable and accurate.

Mine is cold showers. But then I did got a Public School. The school motto was "omnes pares cum frigidus imber" all men are equal when in a cold shower

With 'Green' credits, not having to pay for local grid connections (in some cases), selling power at peak times (via storage), the new agricultural policy. If you can generate enough power, then selling it is easy.

When I was looking for PVC pipework for the spa baths, everyone recommended Hunter Plastics. Can't ever remember having a problem with their products, as long as the boys fitting them did they were told.

About as much use as putting filter tips on cigarettes. It is a shame that the standard of scientific understanding is set by the manufacturers of energy saving products.

Where will use that saving on a short shower, say 2 or 3 minutes. I think the problem with these devices is they need a relatively long time to start recovery processes. Energy scavengers, which these devises are, are rarely worth it in practice.

Yes. Nothing to loose now.

Or recrystallization

Combination of sea air and slug pellets. Or, much more likely, just because it is a different bean type.

Probably not as efficient as running one larger HP. ASHPs have better efficiency at part load. The idea is to not run them too close to maximum. Think this is Jeremy's spreadsheet. Heat loss calculator - Master.xls

So in winter, with the windows closed, thick curtains drawn, and an ASHP drawing minimum loads on setback temperatures, do you really think that a properly sized, located and run, will be a real problem, or one you want to imagine may happen.

At last I can slip the joke in about making it 12" long. Fold it in half.

As I say to farmers, only if you leave food out for them.

V2G or L seems a bit of an odd concept to me. I can see that the concept is attractive, but in reality you just drive about carrying extra mass because the batteries are part depleted. No one has thought it a good idea to run their oil central heating of the car's fuel tank. The arguement goes that when a few million people get home from work and shower, cook, watch TV, etc, the vehicle can supply some of the load and reduce the strain on the grid. Cheaper and easier to just fit static batteries where they are needed. If people can still get off peak power at 5p/kWh (my night rate is 14p) and peak power at 30p/kWh, then you are hard pushed to beat that.

Going to be a large heat pump. What can you do to reduce the heat load of the property.
