New Boiler Savings Calculator

boiler efficiency calculator

Welcome to our Boiler Efficiency Calculator. This tool will help you estimate the current efficiency of your boiler based on a few key factors. Please note that this is a simplified calculation and may not reflect the exact efficiency of your boiler. For a more accurate assessment, consider having a professional energy audit. 

How to use the boiler efficiency savings calculator:

Rated Efficiency: Enter the efficiency rating given by the manufacturer. This is usually found in the boiler’s manual or on the manufacturer’s website. Enter this value as a percentage (for example, for an efficiency of 90%, enter “90”).

Age of Boiler:  Enter the age of your boiler in years. If you’re not sure, try to estimate as best you can. The efficiency of boilers typically decreases as they get older, especially if they’re over 10 years old.

Serviced in the Last Year: Check this box if your boiler has been serviced in the last year. Regular maintenance can help a boiler maintain its efficiency.

Usage Level: Select your boiler’s usage level. If your boiler is only used for heating a small home, select “Light”. If it’s used for heating and hot water in a medium-sized home, select “Medium”. If it’s used for heating and hot water in a large home, or if it’s used in a commercial setting, select “Heavy”.

Once you’ve entered all the information, click “Calculate” to estimate your boiler’s efficiency. The result will be displayed below the calculator.

Remember, this is just an estimate. Many factors can affect a boiler’s efficiency, and this calculator may not take all of them into account. If you’re considering replacing your boiler, consult with a heating professional to get a more accurate assessment of your current boiler’s efficiency and the potential savings you could achieve with a new boiler.
