Gas fired Steam Boiler replacement questions
Hello. I currently have an old Thatcher boiler which starting leaking. I hired a cast iron welder to weld the part, but was unsuccessful-- still leaking. Rather than repair we opted to replace with another compatible steam boiler. If you are familiar with Thatcher, it has a millivolt system which operates the system without the assistance of electric, a feature which I am not willing to live without. The newer system is a steam boiler with the millivolt and 280 btu. My concern is the compatibility with my current system of 180 btu. My home is 2300 square feet and I have 11 registers/radiators. Pipes are 1.25" diameter. Can the system be adjusted to fit my home? and will entire pipe system need to be replaced?
