Evaluation of retrofitting a conventional natural gas

The efficiency of a natural gas fired boiler can be greatly improved by adding a condensing heat exchanger to recover the latent heat of the water vapor entrained in the flue gas. The resistance increment to the gas stream due to the addition of the exchanger is quite small, and the impact on the heating system can be neglected.

15 Ways To Increase Boiler Efficiency Rasmussen …

This results in increased boiler efficiency. Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy will be carried away by the flue gas. On the other hand, the boiler system takes in cold water, heats it to steam, and uses

Oil vs Gas Boiler Installation: Compare Prices, Pros

The truth is that both modern oil and gas boilers are highly energy efficient. A quality oil boiler can give you about 80-85% energy efficiency, and a standard gas boiler will give you about the same. If you are looking for much greater efficiency, you should consider a high efficiency gas boiler, which will give you 92% + efficiency.
