I have a couple of questions:
1. The distributor/plumbers merchant here in Estonia advises 12mm plastic coated copper for the piping from tank to boiler (it is normal here) to help against frost/freezing (we occassionally get -30deg). Any advise - should I stick with 10mm?
2. Should i bury the pipe with a heating cable to protect it also or just bury it in a larger diameter plastic pipe with insulation?
3. Is the whole freezing of oil (28 sec) over played I thought maybe 50deg it might freeze.
Thanks.
