Hello,
What would be the proper size expansion tank on my boiler. I have a Weil-Mclain WTGO-6 boiler with copper baseboard. I have a #30 x-tank in their now. The boiler is brand new. The x-tank about six years old and is from the old boiler. My pressure on the boiler get up to 30 and the relief valve (new) opens. Any suggestions.
Thanks
Scott
