I currently have a steam based modulating Zone heating system. The Boiler is a Weil-McLain oil-fired natural draft steam unit. Throughout my home I have individual modulating units called “SelectTemp” that are made by a company called Turbonics. These units are about 50 years old, parts are available but it is no longer feasable to keep them running.
The low pressure modulating units have a 3/8 inch supply which steam enters a small turbine then through a heater core and leaves through a 3/8 inch return line. No electric required.
I am trying to find out if there are any decorative steam radiator units that would be able to plug into the existing steam infrastructure, without having to rip my house apart
