1. What is a Gas Boiler CO2 Calculator?

Definition: This calculator estimates the carbon dioxide (CO₂) emissions produced by a gas boiler based on energy consumption.

Purpose: It helps homeowners, environmentalists, and energy auditors understand the carbon footprint of gas boiler usage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CO_2 \) — Carbon dioxide emissions (kg)
• \( E_{kWh} \) — Energy consumption (kWh)
• \( 0.183 \) — Emission factor (kg CO₂/kWh, UK standard)

Explanation: The energy consumption is multiplied by the emission factor to calculate total CO₂ emissions.

3. Importance of CO2 Calculation

Details: Understanding CO₂ emissions helps in environmental impact assessment, carbon footprint reduction planning, and meeting sustainability goals.

4. Using the Calculator

Tips: Enter your gas boiler's energy consumption in kWh and the emission factor (default 0.183 kg CO₂/kWh for UK). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 0.183 kg/kWh emission factor?
A: This is the UK standard for natural gas combustion. It may vary slightly by region and gas composition.

Q2: How do I find my boiler's energy consumption?
A: Check your energy bills or smart meter data for gas usage in kWh. If in cubic meters, multiply by 10.35 (conversion factor).

Q3: Does this include indirect emissions?
A: No, this only calculates direct emissions from combustion. Extraction and transportation emissions would be additional.

Q4: How does boiler efficiency affect this?
A: More efficient boilers produce the same CO₂ per kWh but need less energy overall for the same heating output.

Q5: How can I reduce these emissions?
A: Options include improving insulation, using thermostat controls, upgrading to a more efficient boiler, or switching to renewable heating.
