Whats More Cost Effective, A Heat Pump Or A Boiler?

Heat Pump or Boiler - Which Makes The Most Sense Today

The key question for anyone considering heating upgrades in Exeter or the surrounding area is whether to upgrade to a heat pump or continue with a gas boiler.
To put it simply, let's examine cost, comfort, and carbon.

Upfront Costs - What To Expect

The cost of installing a typical gas boiler could range from £2,500 to £4,000.
A contemporary air-source heat pump costs more, typically between £8,000 and £12,000.
However, there is a catch: you can receive up to £7,500 off that cost through the government's Boiler Upgrade Scheme.
This frequently results in a heat pump costing about the same as a brand-new, high-end boiler.

What You Should Expect To Pay In Running Costs Each Year

The efficiency of a heat pump is around three times that of a gas boiler.
This implies that you receive about three units of heat for every unit of energy you purchase.
Your yearly heating costs can therefore be reduced by 20–40% if your house is properly insulated and your system is configured.

Comfort - The Way Heat Alters As Well

After quickly blasting hot water into your radiators, gas boilers turn off.
Heat pumps provide consistent, mild warmth throughout the day.
That means there won't be any more "cold morning shock" and your house will have a more consistent, comfortable temperature.

Cutting Your Carbon Footprint

Compared to a gas boiler, a heat pump that is powered by the current UK electrical grid emits about 70% less carbon.
Additionally, you can achieve nearly carbon-free heating if you combine it with solar panels.

Future Proofing & Lifetime Costs

The future is electric heating.
While petrol costs fluctuate, electricity is become cleaner and more reliable.
A properly fitted heat pump will typically be less expensive to operate and retain its value over a ten to fifteen-year period more effectively than a gas boiler.

Which One Is Better For Your Exeter Home?

A heat pump is the best option for the majority of Exeter homes, particularly those that are contemporary or well-insulated.
It's quieter than you might imagine, less expensive to operate, and the UK is moving in that direction.
