Steam boilers benefit from vent dampers more than hot-water boilers, and bigger boilers benefit more than smaller ones. Vent dampers, however, may not be cost-effective with properly sized, newer furnace models. For older oil burners, converting to a flame retention burner (below) is probably a better investment.
In water versions of the boiler, the new Intelligent Oil Boiler Control continuously monitors all aspects of boiler operation, delivering increased efficiency and impressive energy savings. You will find that most new oil boilers have AFUE ratings between 80% and 87%, while gas boilers have higher ratings of 89% to 98%.

Its compact, floor standing design offers an economical solution for homes with moderate heating loads. Input range 19 to 125 MBH. Model Number Capacity ...
Steam boilers must heat the water to a higher temperature, and therefore have lower efficiencies than hot water boilers. Natural-gas-fired boilers are more efficient than oil-fired boilers. Combination boilers combine water heating and heat generation in one unit and can save considerable money on heating and water heating costs.
Ideal for homes in northern regions, Lennox® boilers integrate easily with existing radiator or under-floor heating systems for energy-efficient comfort, all winter long. With efficiency ratings of up to 95% AFUE, Lennox boilers can help you save hundreds of dollars each year in utility bills, compared to older and standard- efficiency boilers.
