With energy efficiency and sustainability becoming key priorities for UK homeowners, the question many people are asking is:
Should I replace my gas boiler with a heat pump?
Both systems heat your home effectively, but they do so in very different ways. Here’s what you need to know before making the switch.
- How They Work
Boilers burn gas or oil to produce heat.
Heat pumps, on the other hand, extract warmth from the air (or ground) and transfer it into your home — even when it’s cold outside.
Because they move heat rather than generate it, heat pumps can achieve efficiency rates of 300% or more, meaning they produce three times as much energy as they consume.
- Running Costs
While the upfront cost of a heat pump is higher than a traditional boiler, the running costs are lower due to their exceptional efficiency. Over time, this can result in significant savings — especially if paired with renewable electricity tariffs.
If you’re not quite ready for a full switch, a hybrid system (a boiler and heat pump working together) can offer the best of both worlds.
- Environmental Impact
When powered by renewable electricity, heat pumps are virtually carbon-neutral.
Boilers, by contrast, still rely on fossil fuels and emit CO₂ during operation.
Switching to a heat pump is one of the most effective ways to reduce your home’s carbon footprint and future-proof your heating.
- Comfort and Performance
Modern air source heat pumps can provide reliable heating year-round and even cooling in summer, similar to an air conditioning system.
They work best with underfloor heating or larger radiators designed for lower-temperature output.
Boilers still have the edge when it comes to quick heat response, but heat pumps win for steady, consistent warmth and lower long-term costs.
- Installation and Maintenance
A heat pump installation requires careful planning — correct sizing, outdoor space, and insulation all matter. That’s why it’s essential to work with a certified installer who understands both boiler and renewable systems.
At Walsh Solutions, our engineers are fully trained in air source heat pump installation and servicing, offering expert advice to help you decide what’s best for your property.
Final Thoughts
Whether you’re replacing an ageing boiler or planning a more sustainable home upgrade, both options have their merits.
If you want reliability and familiarity, a new boiler is an excellent choice.
If you’re thinking long-term and want to reduce your carbon footprint, a heat pump may be the future.
