Rinkaby Rör has good prices http://www.rinkabyror.se/ What is "normal" probably depends a lot on the size and which system you have, but 22mm to the main lines and 15mm out to the radiators should work. Are you going to buy everything new? Radiators and heat pump, or what are you thinking? I bought my radiators cheaply from Rörteknik in Östersund, but Bauhaus also has good prices on theirs but is more expensive on the fittings themselves.
Hello,
Thank you, Peter.
Well, I'm more in the process of calculating what it might cost to install a water-based system from scratch, to potentially delve into the biofuel swamp later on.
I'm looking for used pipes and radiators, but it would be good to know sizes and new approximate prices before searching.
I've also concluded that 22mm and 15mm seem the most "common," so now I have that confirmed.
Can/Am I allowed to run this type of pipe out to radiators?

Prisol pipes are quite common to use although I am not very fond of them as I find it difficult to make visible pipes look nice since they are so soft and hard to get straight and neat.
Regular PEX pipes should all be cheaper.
Oh, I didn't know you could use PEX pipes for radiators. But look at what you learn by googling a bit about PEX pipes...
THANKS!
Forgot one more question...
So you can use, for example, PEX pipes intended for underfloor heating also as waterborne for radiators?
In that case, the price is around 12-18 SEK/m...

Uponor has lots of good info... http://www.uponor.se/templates/Page.aspx?id=792
and applications for different pipes here... http://www.uponor.se/templates/Page.aspx?id=797
According to that page, underfloor heating pipes are not used for radiator systems.

Run pex to the towel warmer, and they can withstand up to 90 degrees, so as long as you stay below that, it should be fine. I simply couldn't handle bending any more copper pipes. 
In many houses, the radiator system is built with blue pipes. Difficult to work with, and you need an insanely expensive threading tool, and hand bending 15 mm pipes is just a dream.
Biltema's prisol is not approved for concealed installation, apparently, the pipe is jointed under the insulation.

My case definitely falls under that. However, it's "seamless" so as long as I don't drive a screw into the hose, it should be fine. I don't know if it's approved to do so, but I didn't have a choice anyway. However, RiR on the other hand doesn't help either if you screw in the wrong place.
I have had the "circulation" on in the regular radiators and these connected (with plugs at the ends) so it doesn't leak so far I can't connect these later once the wall is in place because the connection is directed towards the bathroom and I rather not mess with the old pipes made of iron.
I have a lot of underfloor heating pipes, but their max temperature is around 60 degrees, so I bought the "right kind" i.e., combipex.
Concealed installation, as I understand it, is inside walls/floors/ceilings where you can't easily inspect these pipes. You can do it in some different ways behind waterproofing, such as a subfloor with waterproofing and a warning pipe or inspection hatch.
