I'm new to the forum and have a question about downrating a boiler.
Currenty, I have an old (1940's?) American Standard boiler for the gravity hot water system. A couple of contractors have suggested energy efficient new boilers in the $7k-$8k range. One heating contractor suggested downrating the 300btu boiler to 100k-150k by reducing the size of the burner openings,installing sensor to monitor outdoor temp. and adding something to the water to make it more efficient (slippery?).
Is this a sensible alternative to spending $8k. I believe I can downrate the boiler myself with the help of a local supply house. I would skip the other ideas for the moment. The house has been insulated recently so the 300,000 btu rating is wasteful according to the heating specialists. My heating bills seem to confirm this.
Any suggestions would be appreciated.
