SteamyTea

The same brickies that know nothing about airtightness, and usually get the window openings wrong. Quite impressed with @pocster's solution, quick and easy, and he had the rebar kicking about (cause he ain't got a clue how to use a tape measure yet, the final coping stone won't fit).

I have noticed over the last few months that I am forgetting trivial things. Nothing major. Forgot how to do the ⁰ sign on my PC the other day, and I must type that a few thousand times a year. Alt + 248 if I remember correctly. Forgetting to make tea would be unforgivable and would trigger immediate medical intervention, forgetting the kettle type is trivial.

Just seen this label on the lead. Seems only suitable for normal people.

No, but my Sister liked to buy things from Argos. Has Uccello kettle on the side and eBay will take 55 of your English Pounds for one. https://www.ebay.co.uk/itm/194809657979

Man you goes to bed with problem, wakes up with solution on belly.

Sister got my mother a new kettle. VID_20220411_080239449.mp4

You sure

If you really want to be a local Knob, then a string of old, used car batteries. Just go to the local council estate, should get all you need.

I wear a Dutch Cap when I am there.

Can you drill 3 hole, making a triangle. Then put plugs and screws in. Adjust with your level, slop some puddin all over, drop on the capping. Wiggle about until they hit the screws.

Yes, today us good. Easy 300 mile drive, coffee in Bourton on the Water, arrived at 11:30 and my mother is trotting about. So popped up half the scaffold tower, sanded soffit and fascia, now putting on 1st coat of woodstain. A very good day.

Every bulb in my house is LED. 3W, why I have so much baseload at zero. Takes the meter 20 minutes to realise a light is on.

Called 'integral skin'. Similar chemistry to those black, foam armrest on office chairs and your car steering wheel. Generally if you cut it, it absorbs water, so you will loose some of the airtightness.

Is your damp being caused by condensation, rather than something penetrations the wall. A lime slab is not going to help any really. A lot if insulation will though. To add to @Radiansuggestion about using heater to calculate heat loss, all you need to do is log external and internal temperature difference, then chart and calculate the slope, which will become power (W) per degree (⁰c or K). That way you do not have to try and keep the house at a constant temperature. Worth making a Raspberry Pi based logger, only cost a few quid and you can see what the RH is as well.

Comes down to marginal losses and gains. Heating a DHW cylinder or a buffer tank us cheap and easy. And for 8 months if the year, will probably supply 80% if your needs.

Or more correctly a 5 kW pump.

There is power, kW, and energy, kWh. Power is the rate at which you use the energy up. A PV system is a relatively low power generator, usually a few hundred watts. It is only when you multiply that by the time it runs i.e. 8 hours of daylight, that the numbers start to look impressive. So if you get 100W of power 2 hours a day (0.2 kWh), 400W for 3 hours (1.2 kWh), 2 hours at 1.7 kW (3.4 kWh) and an hour at 2.8 kW (2.8 kWh). When you add that up, 7.6 kWh, it sounds pretty good. But you could only run a 2.8 kW load, purely off solar for an hour. Luckily, because PV systems inject power (VxA) at a higher voltage than the grid, the nearest loads use that power. So say you run a 6 kW load for an hour, and during that same hour your PV generated an average of 2 kW, you are actually only importing at 4 kW, so paying for 4 kWh of energy.

When you buy a product from a reputable manufacturer, you are usually buying into the after sales service. It is nice to be able to get spare parts in a few years time, and you can tap into the knowledge base. Tempted to get one myself.

Try Sea Eagle then

Tastes similar to swan don't it.

Treat your BEV as battery storage. Then you are at least saving 17p/kWh over gasoline.

Like my ex who bought a 4 quid item, from Newcastle. Was a very long drive there and back. Not my car or fuel thankfully.

Do you get your supply by overhead cabling? Lightening strikes are pretty rare my end of the county, but a bit higher your side.

Which is about 5.5 W/m².K.
