Install a used steam radiator we were able to locate. This radiator is 7 sections long, whereas the failed leaking radiator is 8 sections long. This will still be large enough to provide enough heat to the room. A new steam vent will be installed on the new radiator.
He clearly explained what the problem was and provided good options.

Pm on steam gas boiler,took measurements for new radiator

I performed preventive maintenance (PM) in Hudson on a Rinnai tankless water heater, including flushing the heat exchanger to remove mineral buildup. Additionally, I installed a new ice maker valve and line for the refrigerator, removed the PEX piping from the dishwasher, and rerouted the existing line to the new valve under the sink. Lastly, I installed a Utilitech 4’ power cord behind the dishwasher, ensuring a safe and clean setup. All systems were tested and are functioning efficiently after the work was completed.
Mark always does great work.
