Heating Comparison: Gas Boiler vs. Heat Pump in Lisburn

Because heat pumps operate at 300% to 400% seasonal efficiency compared to 85%–90% for a condensing gas boiler, heat pumps provide cost-competitive heating that becomes significantly cheaper when paired with off-peak electricity tariffs.

The government's £7,500 Boiler Upgrade Scheme (BUS) grant provides substantial upfront funding to replace fossil fuel gas, oil, or LPG boilers with a clean air source or ground source heat pump.

Replacing an older gas boiler with a heat pump in Lisburn avoids approximately 2.0 to 3.5 tonnes of CO2 emissions annually, accelerating household decarbonisation as the UK grid embraces renewables.

Yes, immediately. Homes in off-gas areas around Lisburn pay high per-litre fuel costs. Upgrading to an electric heat pump routinely reduces annual heating expenses by 30% to 50% while eliminating oil deliveries.

Fully decommissioning your gas connection and removing the gas meter saves approximately £110 to £130 per year in avoided standing charges alone.

Yes. Existing radiator pipework is preserved in the majority of installations, with only selected radiators resized to deliver comfortable warmth at gentle, low-temperature water flows.
