underfloor heating for 10' x 8' conservatory

[kjacko]

Hi all,
thinking of putting a conservatory in, 10' x 8', with dwarf walls and (obvisously) windows on top.
Been advised on using Bronze opal polycarbonate for the apex roof (for retaining heat?)
Now we think underfloor heating would be better as this room will be used to sleep in when my son stays once a week. Other than that me and the mrs will be using it pretty often.

So....underfloor heating questions;
1. what kinds are there?
2. Does the kind depend on the type of floor we choose?
3. We have a combi boiler does this have a bearing on what method we use? (i've been told that the hot water method requires separate and isolated connections to the boiler?)

Any and all advice would be most appreciated, thanks

There have been many discussions in the last few months.

Search on 'comservatory UFH' and read them.

With UFH you will not get enough heat to use it in cold weather.

UHF will cost about £400 more than a rad! Are you sure you want UFH?

UFH is great, but you must ensure the heat-loss of your conservatory is not too great. I think it's the case that your LABC will only approve a 'heated conservatory' if your construction fabric meets current high standards. Perhaps you don't need LABC input for a small extension like that in your area??

The system is very much dependant on the floor construction, concrete being the best.

So, if you have a conservatory with minimum heat-loss & the best U-values you can achieve with a lot of glass, then UFH is the way to go.
Another option, that we have fitted many times, is a split AC/CH air source heat pump. Cheap as chip & work a treat from a standard 13Amp supply.

But my personal choice would always be UFH.

Thanks Delta,

what is LABC?

Interesting how the OP ignores postings which do not give positive support to his ideas of using UFH.

Even if UFH could give enough heat output ( which it cannot ) one wonders if he could afford the cost of about £20 a day to heat an uninsulated conservatory!

UHF is very expensive for a small area because of the pump and blending valve it needs.

LABC is Building Control who dont support energy wasting schemes.

If you want it heated then it will need a proper insulated roof and not a plastic sheet!

Excuse me?! You got that from one post?
For some reason i seem to have missed your first post, don't know why, maybe i scrolled down too quick.
I asked for any and all advice. Why would i then ignore yours?

I appreciate your advice, maybe your could lighten up a little though. That post read as if your a were telling me off!
Your opinion is that UFH is not good for a conservatory, thanks, i got that. If others concur then it sounds like i should look at other methods of heating the proposed conservatory.

It is not a personal opinion like that I like chicken masala! Its the facts on UFH.

With your construction UFH would need a floor temp of about 55 C which would be too hot to walk on with bare feet! )

Rads would be able to provide the heat output albeit at the high heating cost.

Ah, that's our lovable Tony, he can be Grumpy, but never Dopey.
But just like Snow White; he enjoys 7UP!!

I hope you get sorted with your conservatory mate..............

You need some proper grub tony. Try a bowl of scouse and you won't want that curry stuff any more, nice as it is.

Calm down!! Calm down!! Ray.
I think he'd enjoy a lovely deep fried Mars Bar Supper, the local fayre in these parts.

shall we look at it from a different way

with zero outside to get the temperature up to anywhere near 21% within the hour will take some where between 4 and 6 kw dependant on a lot off things
anything less than 3kw will never reach a comfortable level as the heat loss is greater than the imput

What? Like Chop Sooey?

Trouble with that is that as soon as you have finished you feel hungry again!

Here you are tony,whip this up and get it down yer neck.

INGREDIENTS
Serves 4-6 people

Half a Pound of Stewing Steak
Half a Pound of Lambs Breast
A Large Onion
1lb of Carrots
5lb of Potatoes
2 Oxo Cubes
2 Teaspoons of Vegatable Oil
Worcester Sauce
Salt and Pepper
Water

HOW TO COOK
Takes 4 hours of slow cooking

Cut the meat into large cubes and fry in the vegatable oil until lightly browned all over. You may wish to add some Worcester Sauce at this point for added flavour.

Transfer the meat to a large saucepan and add the onion that should have been chopped into large chunks. Follow this by chopping the carrot into medallions and place this on the meat. Peel and then Finely dice 1lb of the potatoes and place on top of the carrots.

Fill the pan with cold water until it is half full. Break up the Oxo cubes and sprinkle into the water. Add salt and pepper for seasoning. Let the pan simmer gently, stirring occasionally. The large pieces of onion will start to break up and the potato will become soft and will make the final sauce thick.

Simmer for a total of two hours, then add the remaining potatoes that should have been peeled and roughly chopped, along with a few splashes of Worcester Sauce. Then simmer for another two hours.

Serve piping hot with red cabbage, beetroot, pickled onions and crusty bread. You may add Ketchup and HP for flavouring.

op if you think this is off topic try a bowl of that and you won't need no underfloor heating.
