Underfloor heating

[looneyfitter]

100wm2 is 100wm2 no matter what source of energy provides it so yes.

Thanks looneyfitter.

I can remember reading on here about the manifold and I'm assuming that it's one port per 90/100LM, which means I would need 4 ports.

I have just found this kit and I'm not sure if it's what I need http://www.theunderfloorheatingstor...g-standard-room-kit-to-cover-37m2-2345-p.asp.

Can you tell me all the items I require, so I can check If I can sours them cheaper rather than buying them in kit form.

Thanks.

link dont work matey, You need a 2 port flow and return manifold per 100lm (10M2) Its usually an extra 30 quid per port so i usally add an extra 1 for good measurel

Then you need a blending kit, pump kit, isolation kit,pipe,insulation clips etc.

Do a search on Emmeti

I was looking at a gas bill today of about £1000 per month in the winter and the gas unit charge was 2.63p/kWh.

For electricity it might be about 12p/kWh.

I dont see how you can imagine that electricity is the same price as gas.

TOny thats not what im saying mate. What i am saying is that 100w is 100w. How much you pay for each is a different matter. The actual floor temp will still be the same. Couldnt tell you what is more expensive elec or gas

SCARES ME TO LOOK AT MT CONSUMER BILLS

Hi looneyfitter.

The 3 items that you listed came to around £200.

The blender and valve was identical, so I have only included 1, if I do need the 2 then it will increase to £265.

400m of pipe cost £270.

I'm allowing £100/150 for timber and fixings.

I've been told I need around 1 tonne of sand and I've allowed £80.

Around £150 for ply.

I'm not sure if I"ve covered everything, but with what I've got already it comes to £915 if I need both the blender and valve and £65 cheaper if I don't.

All other materials should be the same compared between wet and electric, the only thing I'm not sure of is if the insulation used is identical..

Thanks.

See if this link works.

It's under warm water heating and it's £581 to cover 50m2.

Thanks.

 

[looneyfitter]

You only need 1 blender matey. IIRC 1 bag of KILN DRIED SAND!!!! covered 1m2

2 by 1 plained batton costs peanuts so wont be any where near £150.

Ply is about £15 for 1200 by 2400

Screwfi was the cheapest for insulation. Silver foil back was 100 quid

 

[looneyfitter]

That looks cheap enough. It looks like its a 1 circuit system tho. Id be looking to Split the load into 5-6 circuits
Give them a ring and ask how many port are on the manifold

Thanks Guy's for all your help.

Sorry to have wasted everyone's time, but I have decided that I am just going to install radiators.

As I was not in complete control of the original Bungalow, I am not confident that this is going to be successful and heat the area up enough.

The worst thing that can happen is that after finishing the property off, the heat to that area isn't enough and then I need to use separate halogen heaters or similar.

Although this isn't a major problem for myself it would be unfair for me to pass this on to someone else.

I have no intention of staying at this property for long and hopefully within a few years I'll have enough funds to sell and do a self build (which is something I've always wanted to do).

I really appreciate all the help you have given.

I now know how U/F heating works and I will never be buying the electric stuff.

Thanks.

 

[looneyfitter]

Not a problem, it's been emotional. Have you thought. About zoneing your rads?

 

[deuce22]

Can you explain how that works.

I am going to be placing them around the whole area evenly, so that I can try and get as even a heat as possible.

Thanks.

 

[looneyfitter]

Sorry just thought on your heating a single area so no point. But basically a linnear valve fits to the flow and a programmable stat controls that rad. Enables you to control rooms individually
