Also, has anyone out there used JG Speed fit fittings for a central heating system? Are they appropriate for those sort of temperatures?
MOST JG Speedfit fittings are fine for central heating, but be careful - there are some fittings that are rated to a maximum of 65 degrees - like this isolating valve.
You're fine with ordinary elbows, tees, coupling etc. If in doubt, check the product packaging or the JG website.
