SteamyTea

Welcome back. I will come over hand help (make the tea) while the strong boys do the lifting. There are still discussions about 'thermal mass'.

You do, you get the hurricane season. How does that affect your building standards/codes?

The other day I had a look at when we bu8ilt our last CCGT, It was 2016. https://en.wikipedia.org/wiki/List_of_active_natural_gas_power_stations_in_the_United_Kingdom

@Mike That video starts and stops in Portreath. The smelliest place around here and not where the Heat The Streets project has happened, that is at Stithians.

Greg Jackson has just been on Radio 4 with his solutions. He has not said anything new, different or clever.

To a certain extent yes, but with solar slates the STP windspeed will be very different.

Welcome I dreamt that I was in the Bahamas, then awoke, and found I was in my pyjamas.

Probably can't be done realistically. It has been, untill the last few days, but exceptionally mild this winter. And last winter, and the one before. It would be fun to build a house down here that is truly off grid and zero combustion. But no one is going to give me a £1m to try it out. £1m would buy 2/3rd of a 1MW wind turbine, so producing about 2 TWh of electricity a year. Or enough to power 650 houses like mine.

By banishing parasite loads, reducing the 7 hour window down to effectively 2 hours, keeping DHW temperature as low as practicable, no tumble drying, and constant monitoring. Yesterday I used 14 kWh, 4 more than my target. But I was in a lot yesterday and used a fan heater (been to mild to turn heating on as only had the odd couple of cold days). Not unusual in the non winter times to use less than 4 kWh/day. I do live alone which helps, and my house is small. An A2AHP would be great for space heating, and an EAHP for water heating might fit. Fitting 2 to 3 kWp of PV is probably the cheapest option for me, even with the compromised roof angles.

Except about half our electricity come from hydro nuclear, wind and solar. Some comes from biomass and waste, but that is as bad as coal burning. No they are not. The users are uncontrollable. Nearly all the ones I see have the input and the output set to maximum, and the users say the house is too hot in the morning and cold in the evening. The problem I have is that I need planning consent, which I would probably get, but the big problem is that I use about 1 MWh/year for space heating. That is about £150/year. DHW is about £225/year. I hope to move in less that the ten years it takes to hit break even.

I had an annoying draught from the door cill. Kept putting off repairing it for years. Last year I got around to it, took 2 minutes, was a couple of loose screws.

Is there a problem with the way the are currently mounted and used?

There was a company down here that were going to specialise in marine renewables testing, an oil company came along and asked how much to use the facilities. The company took the money. (Part of my council tax is paying the debt that WaveHub created) Because like is not simple.

I had never heard of them, in a domestic setting, until someone over at the other place mentioned them. I used to make the window frames out of glass reinforced phenolic resin for the 125 trains. Totally different criteria though, was all about safety. Try doing a search for them, bound to be a lot of people doing them.

How about GRP or stainless steel? I think the problem with all material selection is not the materials, but the manufacturing and installation. Usually material limitations can be designed out.

They have different sizes, surface areas, form factors and volumes though. When it comes to thermal effusivity, which is the product of specific heat capacity, density and conductivity, the materials hopium and unobtainium are often used as examples.

The Manacles.

Was taken to Whitstable to see the sea when it was frozen, think it was in 1973.

I had the same with EDF, but got £200 out of them. I thought, and was mentioned when I studied contract law at college, that 'silence is no acceptance', but it does not seem to apply any more. Certainly did not with Students Loans. These were initially interest free, but now, even on the old ones, charged at a greater rate then bank loans.

I have never known it anywhere near that cold down here, but then we do stick out a long way into the Atlantic.

Ha ha. Good job I have not turned my heating on.

Probably. But mass, in itself, does not correlate to power. There is a lot of misunderstanding and myths about heavyweight and lightweight construction. Even when I have read papers about 'identical' house, with different construction methods, on closer inspection, they are not identical at all. I once went to see a 'solar house' in St. Issy, it had a huge block of concrete inside to help stabilise the temperature. This concrete was around the internal air temperature, so, at best, very little power delivery. The 0.4m of polystyrene, and the 'Toblerone' shape would have made the biggest difference. Adding 'thermal mass' sounds scientific, but as it cannot have meaningful units associated with it, it is just puff.

45 years ago, I had 5 for motoring offences, they took my driver's licence away and burnt it. That's how. (Odd term for a penalty)

Many years ago the house commentator and influencer Kevin McCloud mentioned me (with reference to 'thermal mass'), it was not a glowing endorsement.
