Are plastic pipes suitable to use with radiators?

Question

Hi all, 
We’ve had some pipes replaced recently by a professional plumber to resolve some problems. Although, the issues have been resolved, I’ve since noticed the pipes themselves are plastic – I have some concern about this as these are pipes connected directly and indirectly to the radiators and the boiler. 
Given the heat that could be involved, this is a concern to me – is this normal to have plastic piping used like this nowadays?

Yes if they are the push fit John guest pipes they are suitable for central heating.

Yes, this is normal practice although I would recommend having any visible pipes in copper.

Hi,

Depends on the plastic pipes that have been used. Some plastic pipes are made to take the heat now. Personally, I wouldn't recommend, but you can.

Paul · Answer

Hi There Plastic pipes to radiators are perfectly OK. However, plastic should not be connected directly to boiler. These should be in copper for distance-check with manufacturer- before changing to plastic.

You can use plastic pipes for radiators as long as they are “push fit” style pipes. They are rated for high temperatures from a heat source as long as they don’t exceed a set temperature which is determined by the manufacturer.

Plastic is fine as long as it’s installed probably, I only ever use plastic if it’s not on show and copper everywhere else.
