I have a NIB,NOS Wilesco D14 that I installed a 110V immersion rod heater in the boiler & added 1" pressure gauge I would sell if your interested, only fired to test my work $225 + shipping, a video is on my YouTube channel.
Thanks for the offer!....I am making investment in 2-3 sizes of BIX burners and pipe and valves to run them. Also I am afraid of old electronic heaters around metal boilers and water!
Your new equipment would be fine, but at this time I am trying to avoid electronic boilers...I know some folks really prefure them...
