200L / 380L Boiler Pressure?

Finespirit

Hi, did anyone add a pressure relief valve to the 200L and 380L SD boilers (single wall used with electric heating elements)?
thanks

I've looked into it. There are some really cheap home made ways to do it using water and a pipe (nanometer) or some VERY expensive ways to do it using bursting discs. Some people are using multilayers of aluminium foil over a triclamp fitting too.

There doesn't seem to be very many easy middle of the road applications. I'm not sure a common water heater valve is going to have the capacity or the workability to function like that and we don't know what materials are in them.

I bet the heavy duty aluminum foil over a tri-clamp gasket would work great... easy to test too, just use water, 2'=1PSI or .1m=.1bar maybe have a hose you can dunk into a bucket case it fails during a run... or leave in the bucket for fail-safe
