Don't joke about that. Had a very drunk woman that sat in the corner and wee wee'd herself, and a small boy that pissed up the drinks cooler. And, why I think about it, a guy that let go of just about everything at the counter, though he did have an illness. Was still down to me to clean it all up. Still, I am not the local butcher, carnival night a year back, saw two lads weeing though his letter box. Think it may be a comment on his customer service skills though.

That is almost 3.5 kW of power on permanent (assuming your kw is really kWh). Do a meter reading tonight at 8 PM, and another at 8AM, then another one at 8PM. Post up the numbers as something does not seem right.

Come and dump in in my shop, all the other (expletive deleted)ers do.

Actually, if you do not need logging, I have a cheap indoor/outdoor thermometer from Lidl. The outdoor bit is wireless.

If you can run a bit of flex between the tank and the display, then a Raspberry Pi, with a display, can do it.

Pressure tells you very little about the flow rate. I can pump my bike tyre up to 120psi, and my car tyre up to 36psi. The car tyre will still have a larger volume of air in it.

Have you actually checked the flow rate to your house and what you can realistically supply to 4 showers running at the same time? You can reduce the flow rate, 9 litres/minutes is a pretty good shower. Avoid a wood burner, they are horrible, and not as cheap as people think.

Q = k×A×ΔT Where: k is the coefficient of heat transfer of the heating device (W/m²×°C) A is heat transfer surface area of the heating device (m²) ΔT is the temperature difference (°C) You really need to know the room by room thermal losses before you can start to work out radiator types and sizes.

They are still assuming that modern ASHP are the same as ones from 20 years ago. There is a set distance from neighbours windows and doors, but noise will not be a problem. Odd how some government department is encouraging the use of ASHP and others are trying to stop them.

I heard/read, on here I think, that the carbon intensity of grid electricity is dropping for SAP purposes. May be worth checking that out. https://www.cibsejournal.com/general/sap-in-building-regulations/ And do yourself, and everyone else, a favour, forget all about wood burners.

Yes, PV is much more versatile, and reliable. Is there anything you can do the the building fabric to up your SAP? i.e. add an extra inch or two of insulation, triple glaze windows, better doors.

Well I went to their website, but could not find a way to restrict their data collection. So left.

As does CT1

I have kept out of this as I know nothing about it. But, as I like voicing an opinion. If the walls are 2.7m high, how much room is there at the bottom, the width and length. Could you make a slide? Every degree from vertical reduces the downward force. At 30° it will have 87% of the apparent mass, 45° 71% and if you can get to 60°, then half the apparent mass.

That nicely sidesteps the particulates that are in the house that the wood burner is installed in.

Can't do anything about that, except develop a wireless solution, like I currently use. So when your import meter is constantly lit, and your export meter is flashing, you know that you are self generating and exporting. When you are importing and generating, both will flash. Sound like a third meter, with a CT clamp may be needed. Many years ago I rigged up two meters with 7 clamps to work out the flows on a 3 phase PV system, matched the usage, imports and exports very well. As Damon says, not perfect, but pretty good.

Well my CurrentCost, coupled to an RPI is good, shame they don't make them anymore. A few on eBay though. I have seen a project to make one that reads the LED pulses on a meter, that should cope with PV as you can put a sensor on each meter (I assume that the the LED still goes on permanently when exporting.

Probably only need to go up to 45°C, so should be a little higher. There is also a quirk when the external air temperature is between 0° and 7°C, the CoP can reduce. This is to do with frosting. On a really cold, but dry, day, the CoP can increase. Have you read the stuff on here, and over at the other place, about views on woodburning? Not a good thing.

And energy is too cheap to change habits/goods.

Why don't more people on here use an energy monitor and logger. Would take all the guesswork out if it.

As Dave says, bad design and execution are not a substitute for reality.

I had that problem. I cured it by putting sharp spikes in my flower pots. Made them from old slates. Works a treat, they shit in the neighbours garden now.

One of my sister's ex husbands has leukaemia, along with one of his brothers. He seems to have it all under control now and I don't think it is affecting his life anymore.

Right, yes. Why the outside of a building needs to be wrapped in a windproof barrier. It is also why adding excess mass does not aid temperature stability. There is enough mass in plasterboard and OSB for that.

Too true.
