commercial district heating

[darkart]

I wonder if anyone can recommend a good book that discribes the correct method of installing commercial district heating pipework in properties.

Steel pipeworking is being fitted in loft areas and down the side of a gable end wall and being run in 35mm steel pipe.

Dose anyone know how far apart the support brackets should be fitted from each other on the pipework, what is the distance from pipe connections, should the pipework have sleaving through walls, and should rubber insulation be fitted on supports to prevent creaking of the pipework due to expansion and contraction. Should pipework in lofts be insulated.

Any further advice would be appreciated.
Thanks

Quite an obscure set of questions for this forum?

I would do clips on 35 (1.25") steel at about 1.8m centres or in a loft, wherever the joists/trusses landed close to that. Insulated in a loft for sure.
Rubber lined clips will help with thermal and sound insulation.

Ok, so I'm a nosey git. What's the job?

Yeah got me intrigued as well.

Are they/you fitting heat meters in every property or just letting it run.

Thanks mate, its a repipe to replace some rusty pipe that a guy is doing for me, I just wanted some info to get a rough idea of what the finished pipe-work should look like. I dont want all the hassle of trying to get them back if its not fitted right.

Expect something like Kooltherm to be used for the lagging

Thanks Lee, is there a certain thickness of lagging they should be using for the 35 mm pipe?

I've got a pamphlet somewhere with all the sizes but I'll take a wild stab in the dark at 25mm for kooltherm.

I'd have gone 25 even though that's effectively like 35-40mm of crap stuff.

If have thought 35mm copper an pressfit would be better internal than runs of iron, certainly quicker.
