New Boiler


Does anyone have any thoughts on the pros and cons of replacing a 50 year old 144,00 btu cast iron boiler with a copper fin boiler.

Higher efficiency for lower energy use and smaller energy bill.

Before you toss the boiler try changing to a new high efficiency Beckett or similar brand gun. If you had your present gun tested probably under 50% and a new closer to 85% on oil higher on gas

Get rid of that dinosour. The AFUE even with a new burner will be about 60%.The combustion efficiency may be as high as 85% but the thermal and AFUE efficiency is lost.
You can go to any new boiler and save big bucks. The most important step in replacing the boiler is to properly size it and pipe it properly.
For more information on proper sizing and FAQ on proper sizing see the website below.

Good chance his current burner is in the mid 70% SSE range.

Power gas burners are not very efficient. And if facy can cost you more to use in boilers design for a high temp in the combustion chamber.

Putting a new burner in his old boiler will save money on his heating bill, but not nearly as much as replacing it with a low mass boiler.

If his old boiler holds 30 gallons of water, and a copper fin holds 5 gallons.
His standby loss is reduced by over 70%.

A new burner can get him 82 to 85% combustion efficiency, and maybe get him a AFUE of 70% on his old boiler.

beenthere; Thanks now that is great and clear info. It made it clearer for me to understand what I did last year. I had an old Burnham V3 with updated beckett, kept it running a perfect as I could however I got a great chance and deal on a Weil Mc Lain Gold 4 section steam boiler. Way shorter cycle times to a head of steam, cut oil by about 40%. Guess it is what you called a low mass boiler. Is a wet base CI, but the way is is setup is really good, pre and post purge ect.
