Electric Boiler Size Calculator
Find out the correct size electric boiler for your home. Our calculator helps you estimate the required boiler size based on the size of your home and heating needs.
Understanding Electric Boiler Sizing
Choosing the right size electric boiler is crucial for maintaining comfort in your home while ensuring energy efficiency. An undersized boiler will struggle to meet your heating needs, while an oversized boiler will lead to excessive energy consumption.
Factors Affecting Boiler Size
| Factor | Description | Impact on Boiler Size |
|---|---|---|
| House Size | The overall square footage of your home determines the amount of heat required. | Larger homes require larger boilers. |
| Number of Bathrooms | More bathrooms generally mean higher water usage and increased heating requirements. | More bathrooms may require a larger boiler. |
| Number of Radiators | Each radiator needs a certain amount of heat output to maintain room temperature. | More radiators increase the size of the required boiler. |
| Insulation | Better insulation reduces the amount of heat needed. | Homes with higher insulation require smaller boilers. |
How to Estimate the Required Boiler Size
The formula for calculating the boiler size is:
Boiler Size (kW) = House Size × Heat Requirement Factor + Radiator Factor + Bathroom Factor
Boiler Size Calculation Example
If you have a medium-sized house with good insulation and need to heat several bathrooms, your calculation might look like this:
- House Size (2000 sq ft) × Heat Requirement Factor (50) = 100,000
- Additional Factors (Radiators, Bathrooms, Insulation) will adjust the total size needed.
Recommended Boiler Sizes for Different Homes
| Home Size | Boiler Size |
|---|---|
| Small Home (up to 1000 sq ft) | 6 - 9 kW |
| Medium Home (1000-2000 sq ft) | 9 - 12 kW |
| Large Home (2000+ sq ft) | 12 - 15 kW |
Installation Considerations
Once you know the required boiler size, make sure your electrical system can support the power needs of the boiler. Installation of an electric boiler should be done by a qualified professional who can ensure that the unit is installed according to local codes and safety standards.
