Central heating using radiators in an open plan house with high ceilings

[The Natural Philosopher]

patently, you never have.

[The Natural Philosopher]

50% right. You need to bring it on typically a vouple of hours before you would a conventional system, but simple temp monitoring workes prtty well for me. Teh feed forward is just a differentail applied so that te heating firtes up a bit when it senses a falling temperature coming towards the required temp. Its a bit of a nicety and not really necessary.

From what I remember hearing in other

Possibly, BUT with decent isulation its really not necressary. maybe it koncks a percent or two off teh heating bill.

You know nothing of CH control, especially UFH control.

Most certainly, in a changeable climate like the UK.

With decent insulation, and a house that is reasonably well air-tight with good insulated windows (low "e" or triple glazed), you don't need UFH at all. A couple of fan Mysons can bring the house up to temp very quickly and incidental gains will keep it ticking over.

I'm just wondering why you use the newsreader you do to spread the threads that you reply to all over the group.

[The Natural Philosopher]

Posssibly not, Eliza. But I have been running it successefully for 2 years, and the above is what I have found in practice.

But don';t let practical excpernec get in teh way of glossy brcxhures and teh Bunper Book of How Things Work.

yeaj, right.

No he's right. As long as you hermetically seal the house, and use enough insulation to fill everything apart from a small space in the centre where you can stand, then this should be more than enough........

Certainly not.

More luck than design.

Exactly. Keep away from them.

Good, you are learning.

[IMM]

You are getting it. Look at the Canadian R200 standard. Regularly implemented in Canada and all over the world. They achieve air-tightness no one in the UK can. You are used to bad design and construction and think it the norm. Sad really.

[Andy Hall]

I prefer to open the window rather than live in a hermetically sealed box....... .andy

You didn't look at the spec did you? They have heat recovery and vent, which is a better than opening windows, especially in sarf Lahdan or the towns around it. All those burglars waiting to climb in. Heat recovery and vent give a permanent fresh feel to a house.

[The Natural Philosopher]

teah, and teh capital cots of all that exceeds my annual oil bill by a factor of 100...not to mention the energy used in making it all...

[IMM]

You need to look again.

[Andy Hall]

I don't need to look at the spec. I simply want to open the window when I want fresh air. What do you find difficult about that concept?

I think he is trying to say (but not succeeding as usual) that you would not need to open the window, unless you want to, there is a difference between wanting to open a window and being forced to open a window - would you really want to open a window if there was a force 9 gale blowing towards it ?...

[Andrew Gabriel]

I'm just wondering why you use the newsreader you do that can't work out it's part of the same thread ;-)

Actually, looks like he's using a mail-to-news gateway, and something (that gateway or his mail client or whatever converts news into mail for him in the first place) is losing or failing to create the References (or In-reply-to whilst it's mail) headers.

[IMM]

You can do that with an air-tight house too. But allow all those Sarf Lahdan scallies in the windows? You must be joking.

[Jerry Built]

It may be the MIT M2N g/way. I'll ask.

[Jerry Built]

What a stupid statement. You (WE? Hah!) have not "established" anything. I have enough experience of houses with UFH to form an opinion. "I hate UFH. It is horrible. Ghastly. I would not like to live in a house which has it".

You suffocate.....

[IMM]

half of Canada and all of Scandinavia must be dead then.
