Radiators, storage heaters, power flushes and full new systems. Describe the job and we pass it to heating engineers covering Exeter.
Exeter has more electric heating than most cities its size. 11.5% of households heat with electricity only, rising to 27.6% in St David's ward in the city centre. Another 1,157 homes had no central heating at all in 2021. That means many Exeter heating jobs aren't about boilers.
Exeter at a glance
- Water hardness
- Mostly soft. South West Water says most of its supply comes from moorland rivers and reservoirs and is soft or moderately soft. East Devon, supplied from boreholes, is the one area it treats as hard, so homes on the city's eastern edge should check their postcode. Source
- How homes are heated
- 76.4% of Exeter households heat with mains gas only and 11.5% (6,029) with electricity only. 579 homes (1.1%) are on a district or communal heat network, 1,157 (2.2%) had no central heating, and 135 (0.3%) used oil only. Source
- Electric heating by area
- In St David's ward, which covers the city centre, 27.6% of households (1,319) heated with electricity only in 2021. Exwick was at 19.7%, Duryard and St James at 17.4% and Newtown and St Leonard's at 16.3%. Source
- Energy ratings
- 49.2% of Exeter homes with an EPC lodged up to March 2022 were rated C or above. The figure was 41.5% for privately rented homes, 18.6% for homes built before 1930 and 97.4% for new builds. Source
- Median energy score
- About 41% of homes with an EPC in Exeter are rated band D or below (median score 70, band C), against 47% across England. Based on certificates lodged in the 10 years to March 2025. Source
Upgrading electric heating
Old storage heaters often run out of heat by the evening and are hard to control. Modern high-retention storage heaters with smart controls are a direct swap. An air-to-air heat pump in the main living space is another option, with much lower running costs.
If gas is available, a wet central heating system with a combi may be cheaper to run, but the installation cost is higher. A heating engineer who is also an electrician can compare the options.
Homes with no central heating
1,157 Exeter households had no central heating at all in 2021. If yours is one, a heating engineer can price a full system, either a gas combi with radiators or an electric option where gas isn't available. If the home is privately owned and rated EPC D or below, check the Warm Homes: Local Grant first, as it can fund heating upgrades for eligible households.
Gas central heating
Cold spots, noisy pipes and slow-to-warm radiators usually come from sludge or an unbalanced system. A chemical or power flush, inhibitor and a magnetic filter usually fix it. Soft water in most of Exeter means limescale is rarely the cause.
Upgrades
Thermostatic radiator valves, a balanced system and a lower flow temperature reduce gas use. Bigger radiators in cold rooms let the boiler run cooler and prepare the house for a heat pump later.
Exeter homes and what they need
Interwar and post-war semis
Converting gravity-fed hot water to a fully pumped system with separate zones gives better control and is a common job.
Victorian and Georgian terraces
High ceilings and solid walls mean bigger radiators. Check radiator sizes against room heat loss rather than replacing like for like.
New-build estates on the edge of the city
Some estates use communal heating. Your engineer can work on radiators and valves inside your home, but not on the network itself.
Areas covered
Engineers who cover Exeter work across areas including Heavitree, St Thomas, St Leonard's, Pennsylvania, Alphington, Whipton, Pinhoe, Exwick, Topsham and Cranbrook.
Questions people in Exeter ask
Can I add central heating to an Exeter flat with storage heaters?
Often, if there's a gas supply and a suitable flue route. Leaseholders need the freeholder's consent for any outside changes.
How long does a power flush take in Exeter?
Usually a day for a three-bedroom house. The engineer should add inhibitor and fit a magnetic filter at the end.
Are storage heaters or a heat pump cheaper to run?
A heat pump uses much less electricity for the same heat. Installation costs more, so the payback depends on how long you'll stay and whether a grant applies.
