Pull it apart and see what sensor is in it. Probably a cheap one.

Hard to say, as generally, biomass burners need to work at their maximum to be most efficient. It could be that the heat losses from the TS are higher. Where is it situated? How well insulated is it? Taking @PeterWfigures, the store holds about 18 kWh of useful thermal energy. So should heat up in 2 hours.

30 kg is about 135 kWh primary energy. So once efficiencies are taken into account, you may be getting 100 kWh into the thermal store.

Well short of something being wrong with it, and the EPC numbers being well out, I would think it is.

I shall, for the matters of implicitly, reduce that heat load to 12,000 kWh/year, and assume that the heating is on for 160 days. So that is a mean of 75 kWh/day. But on the coldest days, you will need at least twice that, 150 kWh. Now your boiler is 18 kW, at its very best, in ideal circumstances, but probably closer to 15 kW. So it needs to run, just to cover the heating loads, between 5 and 10 hours a day.

A number of (general) things come to mind. If you can sort it out privately, do so. Can the SE pay, no point claiming against a person that cannot. Can you afford to chase a debt. Was it paid for on a credit card, can you claim on that. It the claim small enough to use the small claims court.

How large is you thermal store, your objectional biomass burner, and what are you heat loads?

The only thing about a cylinder adding energy to a house in winter, is that it is an uncontrolled source and may be adding it into an area you do not want. What you can do is fit it into a well insulated airing cupboard, then put one of the MVHR extractions in there.

The problem is the standards used. If I remember correctly, a standard test just looks at the standing losses over a short period of time. You can estimate the losses over any time period by calculating the losses in the same way you would a walk i.e. the conductivity, times the surface area, times the mean temperature differences.

Yes. And the sun is not getting any hotter. You can work out the max temp from the power of the sun (no more than 1200W.m-2) and the SHC of the material the frame is made from (PVC 840 - 1170 J.kg-1.K-1, Timber between 1300 and 2500). Expansion of PVC is 50-6 m.m-1.K-1, timber 3-30 -6 m.m-1.K-1

Good man. The kind of thing you are spraying is similar to the small things I need to do.

Down here, that is a cove.

This is what I got for a tenth of the price. https://www.screwfix.com/p/kitchen-sink-drainer-stainless-steel-1-bowl-760-x-430mm/6547K Remember 'hands that do dishes, are as soft as your wishes'

You could get one of these. Then send it to me as I want to know if it is any good. https://www.screwfix.com/p/erbauer-erb561srg-700w-electric-hvlp-spray-gun-220-240v/11628

Lightly sand the surface of the paint above the damage. Use some filler to create a new 'paint thickness' below the damage. Lightly sand and then paint. If you really don't want to see the difference, there are some wrist exercises that make you go blind, similar to sanding.

I am coming to that conclusion, this possibly the exception of swimming pools.

That is just an opinion piece from a supplier of lime. Someone had some actual numbers. I can find them for other materials, just not cement and lime (though this may be because the mixes can vary so much). Here is a page that shows how to calculate it, and has some material numbers at the bottom.

I have been looking for some number to back this up (I know someone else did a while back). I seem to remember that there was little difference between a cement or a lime render. There are two units used: kg.s-1.m-2.d-1 and m3.s-1.m-2.d-1 Sometimes this is modified to take pressure into account, this this is not really relevant to building houses, more for testing purposes. I have not managed to find any decent data.

I got a couple of little used angle grinders I don't want.

May smell a bit for a few summers.

Blackout curtains and very dark sunglasses, and pull the lighting circuit fuse. Or ask Steve Wonder.

Worse job I ever had to do was cleaning out the spa bath filter from the Sheffield YMC. I have no idea what those young men got up to in it. @pocster

Is that what you are calling your spare bedroom.

Well that is part of the idea, the treasury gets more revenue. Thing is, many of the items we current purchase as individuals, are not, and cannot realistically, be made in the UK. Now we may be able to produce some, but relaxing employment, environmental and trading standards, but that is hardly progress, and we currently have some rules to stop that happening. Going to be interesting to see if the WTO changes criteria, it is probably been waiting to see the outcome of any trade deals that we manage to see what they can change. Ideally the WTO would agree with all its members that the kind of deal the EU has between member states is a good thing for the world i.e. unhindered free trade and movement of goods, services and people. I would quite like to retire to where I lived as a teenager.

Well like us, more. So we are all winners.
