Understanding Indirect Boiler Efficiency - Forbes

In a typical oil fired boiler, there are three losses to consider : 1. Loss due to water and hydrogen in fuel: This is the difference between GCV and NCV of a fuel, and needs to be considered if efficiency is calculated on GCV. Not much can be done to reduce this loss, as it is a function of fuel constituents alone. 2. Stack loss:

2020-9-8 · Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.

Figure 1 depicts a typical efficiency curve for a condensing boiler relative to return-water temperature. Two main points can be gleaned from Figure 1. First, operating a boiler with a return-water temperature above 140 F yields a peak thermal efficiency of roughly 88 percent. That means it basically is performing like a non- condensing boiler.
