A natural gas burner rated at 40,000 BTUs per hour divided by 1,000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption. Step 1. Multiply the burner efficiency by the energy content of the gas being used.

All modern boilers that you can buy are condensing boilers, which are much more efficient than traditional non-condensing boilers. According to the energy saving trust, you could save as much as £340 a year on your gas
Get A QuoteEvery new boiler carries an ErP energy label, which ranks its efficiency from A-G. Nearly all modern gas boilers get an A energy rating, which means they're highly efficient. SEDBUK This score is the one to look for if you really want to get into the detail, but it's worth noting that a difference of just a few percentage points won't have a massive impact on your bill.

Get A Quote31/1/2014 · We need to look at a boiler's thermal efficiency, which means what percentage the DOE or Gross Output rating is of the Input rating. Typical atmospheric (so-called gas-designed) gas-fired steam boilers have thermal efficiencies of 80-82%, whereas wet-base steamers normally sold as oil-fired boilers and equipped with good power gas burners rate up to 86%.
Get A QuoteThermal efficiency assesses the effectiveness of the heat exchanger by analyzing its ability to transfer heat energy to the water or steam within the boiler. However, this calculation does not account for external factors such as ON-OFF losses, radiation losses, convection losses and more, so it is not the best indication of the boilers' fuel usage.
