Why so many?

Pleeeeaaase, not another endless thread!

That is apart from the OP, who may not be as familiar as the regulars on here, who understand just how odd, and peculiar, Odds actually is.

You seem to be querying how UFH works?

The stat in the Willis, will be subjected to the convection flow of water, being drawn in at the base of the Willis. Only when both the Willis, and the main cylinder reach temperature, will the Willis stat open. However, the Willis system facilitates the inclusion of additional stats, on the...

Warm air, or water, rises. The heat source is in the floor, the floor area will be warmer the air above it, therefore it will rise. The air current will be rising in the middle, because the walls will be cooler. Basic common sense, in my view! I am not going to be drawn into it!

I would suggest the warmed air would rise in the middle of the room, and fall around the walls. With differences in temperature, you cannot not have air currents.

Any sharp, thin edges will rapidly rust away, but if you swap the cutting disc, for a grinding disc, you will be able to grind the sharp edges off. However, once the main weight of the bars have been cut off, and taken down - just hammering the remaining stubs of steel in the wall...

They work well as a tiedown, speading the grip on the earth wider.

Test the limiting the flow first, by turning your stop tap down, and flushing - see if you still hear the thumps.

John, I have tried numerous times, others have gone to the trouble of doing drawings to explain the principle. I don't really see what more we can possibly do, but would suggest you read this - https://en.wikipedia.org/wiki/Thermosiphon That explains, that if you are typing your replies on a...

Often caused by a high mains pressure, and too quick a flow, filling the cistern rapidly. You could try reducing the speed of the fill, either by adding an isolating valve in the supply pipe to each, and not turning it on fully, or... You can fit a disc, with a small hole in, where the pipe...

I don't like fish!

If the plug is wet with fuel, but not firing, that suggests no spark. Some vertical markings on the piston, are to be expected.
