Jan 08, 2016 · Upgrading the boiler from 56% to 90% efficiency in an average cold-climate house could potentially save 1.5 tons of carbon dioxide emissions each year if heated with gas, or 2.5 tons if heated with oil. If the boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is often to replace it with a modern model.

This is why oil fires operate at higher efficiency levels than natural gas. Turndown. Turndown is the ability of the boiler to achieve a wide range (from low to high) of output. If a boiler has a high turndown ratio, then it is able to supply steam at lower rates without shutting down and restarting.

Mar 15, 2009 · Been using wood and oil heat for years. This winter started using coal. It costs about $60.00 a ton, which is about two or three cords of wood burning and to buy wood, it is about $200.00 a cord if you don't cut it yourself. Coal lasts for eight to ten hours on a load where wood lasts about five or so.
