Traditional boilers are dependent on gas which is rapidly increasing in cost, making them a more costly option to run.
Heat pumps are a highly efficient, much greener alternative to other forms of heating like gas boilers.

Frequently Asked Questions
With an increased focus in the the UK to moving away from fossil fuel heating and transitioning to more energy efficient systems, this means that low-carbon heating alternatives like heat pumps are becoming commonplace. This means that it is surely only a matter of time before most households that are suitable will have a heat pump system that will help them use less fossil fuels and save energy and reduce their bills.
The majority of heating systems rely on burning fuel or converting electricity into heat. Ground source heat pumps differ and are more efficient because they don’t generate heat, but instead extract existing heat energy from the ground to be delivered into your home. By providing more heat energy than the electrical energy they require to run the system, a heat pump set up is more cost-effective than traditional heating systems such as a boilers.
The efficiency of heat pumps can be measured by a Seasonal Coefficient of Performance (SCoP). This details the level of heat produced for every unit of electricity consumed. Usually, ground source heat pumps generate between three and five units of heat for every unit of electricity that is consumed, representing a SCoP of 3-5 (or between 300% and 500% efficiency). Compared to this, a standard boiler may have an efficiency of between 60% and 90%+ depending on its age.
An GSHP system needs electricity to work, but uses less than the quantity of heat they extract from the ground, leading to savings. The amount you save will depend on a number of factors including your heat pump set up, the heating system you have replaced, your electricity tariff, and the costs of the fuel you are replacing. If you benefit with a grant towards the cost of installing a ground source heat pump, you could save several hundred pounds on heating each year.
The noise of a ground source heat pump is less than both a gas boiler or an air source heat pump and sounds not unlike a dishwasher. Because there is no fan component and the heat source is warmer (therefore putting less strain on the compressor), this makes them one of the quietest heating options available on the market.
In England and Scotland, ground source heat pumps don’t normally require planning permission and would be classed as Permitted Development unless the building is listed or is in a Conservation area, area of Outstanding Natural Beauty, or a National park. Those in Wales do need planning permission to install a heat pump. If unsure, you should check with the local planning department.
If it is correctly installed and maintained, a ground source heat pump should have a working lifespan of roughly 20-25 years, while the excavated ground loops can last for up to 50 years.
