Air stratification and ceiling radiant heat

Hi AC, This is a bit late, I just noticed this thread. My 2 cents worth:

The temperature of the air in contact with a flat ceiling radiator will have virtually no effect on the heat output of the...

Perforated foil

Not Icelandic, although some of my ancestors do figure in the Orkneyinga Saga. What’s unlucky about being Icelandic anyway? The fact that their ancestors made it across the far North Atlantic in...

Conditioned crawl-space a better idea?

The info in this thread is really good. However, there is another factor that nobody has mentioned. Maybe we are unlucky, or just klutzes, but over the decades we have had several “indoor floods”. ...

Winter is when blizzards arive and blizzards can cut off power for a longish time, especially in the countryside. Seems that that could be a risk when you are away? We had a once in 20 year...

When we lived in Jakarta, we couldn't do all our drying on a line, 95% humidity air pollution and daily thunderstorms meant we only had a small covered area line. We used very small window-mounted...

Having now reread the post on insulation, I'm properly embarrassed. Of course you need to insulate pipes where they might freeze, hot or cold, plastic or copper. My excuse is I'm now in a climate...

I've just replumbed my new-old house with small-diameter plastic piping. Longest pipe run from the central in-line condensing gas water heater is about 12 metres (40 feet). I just completed the...

Hi Gary,

Thanks for the very interesting link. BuildItSolar is a jewel.

You note that the "other Gary" has built an exceedingly robust timber structure. So the reduced costs of the lining must...

Hi Gary,

I certainly would go for EDPM, if I can get it, when I finally finish

Another point about burying the timber inside the insulation is that it will dry out even further than kiln drying can achieve. This doesn't directly reduce strength but may cause cracking around...

Hi A C Hacker,

Hi Daox, Water can only drain faster than the pump can supply if air is able to flow up the pipe against the water flow. Unless the return pipe is over-sized, I am a bit surprised that this would...

I've a question about the pumping heads. Once the flow is established, won't the return pipe, the down leg, be full of water? If it is, won't there be a siphon effect, effectively reducing the...
