Heat pumps in Exeter: installation and grants

Exeter, a city characterised by its blend of historic Victorian terraces in areas like St Leonards and newer developments across its suburbs, sits within a mild but often damp South West climate. This unique setting means efficient home heating is crucial for comfort and managing energy bills, even without extreme cold. Heat pumps offer a modern, low-carbon heating solution, and understanding their place within Exeter's specific energy landscape is essential for homeowners considering an upgrade. This guide provides practical, local information on heat pump benefits, installation, costs, and available grants for Exeter residents.

Why consider a heat pump for your Exeter home?

Heat pumps are an increasingly popular choice for homeowners looking to reduce their carbon footprint and heating costs. They work differently from traditional boilers, extracting heat from the environment rather than burning fossil fuels.

Exeter's climate and housing stock

While Exeter rarely experiences harsh winters, the mild and often damp conditions of the South West make consistent, efficient heating vital. Heat pumps are well-suited to this climate, as modern units maintain high efficiency (Seasonal Coefficient of Performance, or SCOP) even in cooler temperatures. Exeter's diverse housing stock, from older, solid-wall properties to well-insulated new builds, means that proper sizing and adequate insulation are crucial for a heat pump to perform optimally.

How heat pumps work

A heat pump operates much like a refrigerator in reverse. Instead of expelling heat, it extracts warmth from the air, ground, or water outside your home and transfers it indoors to provide heating and hot water. This process uses electricity to move heat, making it highly efficient. Even on cold days, there is enough ambient heat in the environment for a heat pump to function effectively. Air source heat pumps, for example, can achieve efficiencies of 300% or more, producing around three units of heat for every unit of electricity consumed1.

Benefits for homeowners

For Exeter homeowners, heat pumps offer several compelling benefits. They provide an energy-efficient alternative to fossil fuel boilers, leading to a reduced carbon footprint. Over time, this efficiency can translate into lower running costs, particularly as electricity grids decarbonise. Heat pumps also offer consistent, comfortable heating and can increase a property's Energy Performance Certificate (EPC) rating.

Local energy landscape: what Exeter residents need to know

Understanding Exeter's local energy infrastructure is key to making informed decisions about installing a heat pump.

Exeter's price cap region

Exeter is located in the "South West England" electricity distribution region for Ofgem's energy price cap. This means that the unit rates and daily standing charges for electricity in Exeter differ from other regions across Great Britain. The price cap is updated quarterly, on 1 January, 1 April, 1 July, and 1 October, influencing the running costs of your heat pump.

Your local distribution network operator

The local distribution network operator (DNO) for Exeter is National Grid Electricity Distribution. The DNO is responsible for maintaining the local electricity network that delivers power to your home. In the event of a power cut, Exeter residents should dial the free national number 105, which will route them directly to National Grid Electricity Distribution for assistance.

Grants and financial support for heat pumps in Exeter

The upfront cost of a heat pump can be a significant consideration, but several schemes are available to help Exeter homeowners with the investment.

The Boiler Upgrade Scheme

The Boiler Upgrade Scheme (BUS), administered by Ofgem, provides a substantial grant towards the installation of heat pumps in England and Wales. Through the BUS, homeowners can receive a £7,500 grant2 towards the cost of installing an air source or ground source heat pump. To qualify for this scheme, your chosen installer must be MCS-certified, and the heat pump must be sized appropriately for your property.

Other potential funding

Homeowners may also wish to research whether other avenues for financial support exist, such as local council initiatives or specific grants.

Choosing the right heat pump and installer in Exeter

Selecting the correct heat pump system and a qualified installer are critical steps for ensuring efficiency and eligibility for grants.

Air source vs ground source heat pumps

The primary types of heat pumps are air source and ground source. Air source heat pumps extract heat from the outside air, making them generally easier and less disruptive to install, and suitable for most properties. Ground source heat pumps, on the other hand, draw heat from the ground via buried pipes, offering potentially higher efficiency and a more consistent heat source, but requiring more land and a more involved installation process. The best choice for your Exeter home will depend on factors like available outdoor space, property type, and budget.

Importance of MCS certification

MCS (Microgeneration Certification Scheme) certification is not just a mark of quality; it's a requirement for accessing government grants like the BUS. An MCS-certified installer ensures that your heat pump system is designed and installed to a high standard, guaranteeing its performance and your eligibility for financial support.

Finding local installers

When looking for a heat pump installer in Exeter, prioritise MCS-certified companies with a strong local reputation. Obtain multiple quotes to compare costs and services, and ensure that each quote includes a detailed assessment of your home's heat loss and a recommendation for the appropriate heat pump size and type.

Maximising your heat pump's efficiency with Fuse Energy

Installing a heat pump is a significant step towards a more energy-efficient home. To truly unlock its potential, you'll need to optimise your home environment and manage your energy intelligently.

Optimising your home for a heat pump

For a heat pump to operate at its highest efficiency, it needs to be paired with sensible insulation. This means ensuring your home has good loft, wall, and floor insulation, as well as efficient windows and doors. A well-insulated home retains heat more effectively, allowing the heat pump to work less to maintain comfortable temperatures, thereby reducing running costs.

Managing your energy with Fuse

Fuse Energy aims to be a valuable energy partner for Exeter homeowners embracing modern, efficient heating. While Fuse Energy does not install heat pumps, we provide the energy supply and tools to optimise their operation. Our transparent app gives you control and visibility over your energy usage, complementing the efficiency of your newly installed heat pump. With 24/7 human customer support, Fuse offers continuous assistance to help you manage your energy, complementing the efficiency of your heat pump system.
