It is better than red according to @Radian

All fag packets are black now.

Feck, where was he when I got our flat roof GRP'd? Don't know, may have been in Weymouth.

That has to be sorted first. Then look and deal with the fraudsters.

Not as simple as that if Denominator is a variable.

Have a word with @craig, he gives good advice.

Why not go for 60 minutes or better if you can. Sometimes minimum standards are a hazard in themselves.

Wonder if they mean an efficiency of 125% at 55⁰ C output. Most probably the 12 year old in the publicity department misunderstood what was given to them.

Think I get about 70Gb for a tenner. And faster than the landline.

I think my phone uses 43. I find my phone works most places, so may be a cheap option.

Good, professional report that. Don't burn wet wood in an open fire.

Too right. Why knowing what the heat load of the building, at the start of a project, is so important. Sometimes I think they need to put a digital display on a roll of mineral wool insulation. Make it a bit more 21st Century.

But is it worth the cost of a diverter?

How does that solve the problem of a poorly insulated house with high air leakage? Insulation and airthghness does not need to cost a fortune, though it often takes time and can be messy.

Did you see the bit that it was a bunch of Manchurian academics that names it after the slang term for clothing.

A TOG is equal to 0.1 m2.K/W. To get to the nicer to understand U-Value, inverse it. U = 1/RSI

Less fatal

Our log saunas has long coach bolts that were used to tighten up the logs every few weeks when they were first installed. Obviously airtightness was not the main concern with a sauna, but it was not unusual to have a 100°C temperature difference.

Popular in South Africa in the 70s and 80s, trade embargo or no.

I have a sunbed kicking about, moved house with me a few times. Great for warming up on, and you get a tan. Probably delivers around 1 kW/m2. No reason it cannot be wall or ceiling mounted.

Says all you need to know really. If IR was a viable option, ten we would all be using it.
