I have an existing solid fuel heating system and I want to connect up
an oil fired boiler to it.
Please advise on how I should plumb it, I believe I should use some
check valves but not sure where they should go. Also do I need
another circulating pump
Well I suppose I thought someone with more expierience than me might
be able to give me some info. or perhaps a typical flow circuit
showing where the check valves would go etc. Apologies if this is
oversimplfying things. What more info would I need to give.
You need to look at the system in 2 parts, heat source and distribution. Now
you're adding a second heat source, so it has to be plumbed in tandem, or
parallel with the existing source.
Use check valves to prevent one source from heating the other unused source.
