What is the real LED energy efficiency?

I fitted 'posh' florries as under cupboard worktop lights. Philips 32, as the best match to halogen. Osram electronic dimming ballasts. So not the cheapest option.

Date of my drawing, 2002. They are left on as the 'someone is in' lights when out. As well as most evenings when in and its dark. As well as any time the kitchen is actually used.

Never been repaired and still working fine.

Remember replacing a audio meter (PPM) pea bulbs with white 5mm LEDs. Not driven flat out either. They did have a slightly longer life than the very under driven and yellow tungsten pea bulbs, but lost output considerably. To the point when too dim for the job. The pea bulbs just failed. ;-)

Indeed not. Draughts excluded (sic!) windows are not the worst heatloss in a house, just the simplest to install and make profit on.

Roof insulation is no 1 priority, then walls, and then floors. But draughtproofing beats the lot.

S/G windows are fine with double insulated curtains.

Is turning Usenet off part of the net zero thing ?

Does that work just as well for north-facing windows?

Sounds like rather low-end UPVC.

different sort of pollution

Old gas created large particle pollution which "new" gas does not

today's problem is excess CO2

There is no "excess CO2"!! --

But Communism abolishes eternal truths, it abolishes all religion,and all morality, instead of constituting them on a new basis; it therefore acts in contradiction to all historical experience."

These days, hardly any, because of regulations requiring Fensa certs or notification which puts people off.

"Back in the day" replacement windows were advertised in the DIY magazines.

I tried to dig out old gas bills, to see if my heating has gone down by more than £75, I suspect just on draughts alone it will have done.

I have fitted three uPVC windows in my house. Getting the old Boulton & Paul timber windows out was the difficult bit. DIY patio door replacement is definately a 2-person job.

Which includes cavity wall insulation where possible. The air leakage through the cavity in my house, and thence into and through the void between GF ceiling and Upstairs floor was horrendous with a cold north wind.

My kitchen window, 48.25 inches wide by 43 inches deep, with a top hinged casement 9 inches deep, with C-rated D/G glass was £152+vat in 2014.

No answer, I see.

Self-fitted clearance bargain for one window out of a whole house??

And you didn't deny it was a low-end spec (it's the ugly thick frames as much as the glass).

Wouldn't say building work is my best DIY skill, but I've installed two windows and a set of patio doors.

While in the meantime, the slaughtering business is short of it. Is the no way of filtering CO2 out of the atmosphere, and bottling it?

Physically possible yes. There?s a plant in Iceland doing just that. Economically possible without oodles of free geothermal energy, no.

Remember, there?s more argon in air that there is CO2. In relative terms, there?s very little CO2 in air.

But Google tells me that argon is not a greenhouse gas.
