At a glance
| System | Typical install | Annual running cost | Installation | Net zero | Warm-up time | Maintenance | Best for |
|---|---|---|---|---|---|---|---|
| Infrared radiant heating | £8,000 to £30,000 depending on building size and number of zones | £1,500 to £4,000 per year for a typical parish church | Simple retrofit; wall or ceiling mounted with standard wiring, no groundwork | Yes | Instant; warmth felt within minutes of switching on | Low; no boiler, pipework or ductwork to service | Regular weekly services in large, hard-to-heat naves |
| Pew heaters | £10,000 to £25,000 for a typical parish church; larger buildings or three-phase upgrades can push to £35,000+ | £800 to £3,000 per year; among the lowest running costs of any church heating option | Moderate retrofit; units fix under pews with cabling to a central panel, no groundwork | Yes | Fast; warm air felt within 15 minutes of switching on | Very low; no moving parts, occasional visual inspection | Churches with fixed pews and regular services where heating the congregation matters more than the building |
| Air source heat pumps | £25,000 to £60,000 depending on building size and whether existing pipework can be reused | £2,000 to £5,000 per year, potentially less with a good coefficient of performance | External unit needs groundwork and planning; indoor pipework may need upsizing | Yes | Slow; 2 to 4 hours pre-heat typical | Annual service; refrigerant checks and filter cleaning | Churches with regular daily or weekly use that want to move away from gas entirely |
| Biomass boilers | £25,000 to £60,000 including fuel store and flue | £1,500 to £4,000 per year depending on pellet prices and usage | Major works; needs a boiler room, flue, and a dry fuel store with delivery access | No | Moderate; 1 to 3 hours depending on system size | Regular ash removal, annual service, and flue sweeping | Rural churches with space for fuel storage and no mains gas supply |
| Electric panel heaters | £2,000 to £8,000 for a set of panels in a small to medium church | £3,000 to £7,000 per year in a medium church with regular use | Simple retrofit; wall mounted with standard wiring, no pipework or groundwork | Yes | Moderate; 1 to 2 hours for a small to medium space | Very low; occasional wipe-down and thermostat check | Small churches, vestries, or meeting rooms where budgets are tight and use is regular |
| Gas radiant tube heaters | £15,000 to £35,000 for a typical nave installation | £1,500 to £4,000 per year depending on hours of use | Moderate; overhead mounting, gas supply and flue runs through the roof | No | Fast; noticeable warmth within 10 to 20 minutes | Annual gas safety check, burner servicing, and reflector cleaning | Large open naves where gas is already available and radiant warmth is preferred over blown air |
| Gas warm-air heating | £20,000 to £45,000 for a medium nave, more if ductwork is new | £2,000 to £5,000 per year depending on usage and insulation | Major works; ductwork through the building, plant room and gas supply needed | No | Fast; 30 minutes to 1 hour for a medium nave | Annual gas safety inspection plus filter and fan servicing | Churches that already have ductwork in place and need a like-for-like replacement |
| Storage heaters | £3,000 to £10,000 for a set of modern storage heaters | £2,000 to £5,000 per year depending on tariff and usage pattern | Simple retrofit; floor standing or wall mounted, standard wiring only | Yes | Overnight charge; heat available next day, not on demand | Very low; occasional thermostat and element check | Churches or halls with regular daytime weekday use, such as community spaces open most days |
| Underfloor heating | £30,000 to £80,000 depending on floor area and whether archaeological work is needed | £2,500 to £6,000 per year for electric; £1,500 to £4,000 for wet systems | Major works; floor must be lifted or replaced, possible archaeological survey | Yes | Very slow; 4 to 8 hours or more from cold | Minimal once installed; wet systems need occasional boiler servicing | Churches undergoing a major reordering or floor replacement where the slab is already being lifted |
Costs are indicative for a typical parish church. Your building, usage pattern and existing infrastructure will shift these figures. Get a tailored estimate.
Explore each system
Infrared radiant heating
Warms people and surfaces directly rather than heating the whole air volume, which suits tall, draughty church buildings that were never designed to be heated.
Pew heaters
Electric heaters mounted beneath or behind pews, warming the congregation directly through convection or infrared radiation. Discreet and silent.
Air source heat pumps
Extracts heat from outdoor air and uses it to warm the building through radiators, underfloor pipes, or fan convectors. Runs on electricity.
Biomass boilers
Burns wood pellets, chips, or logs to heat water, which is then circulated through radiators or underfloor pipes. Classed as renewable but not zero-carbon.
Electric panel heaters
Wall-mounted convection heaters that warm the air around them using electric elements. Simple to install and familiar to most people.
Gas radiant tube heaters
Overhead tube heaters that burn gas to heat a metal tube, which then radiates warmth downward to people and pews below.
Gas warm-air heating
Blows heated air through ductwork into the building. Common in larger churches from the 1960s onwards, often mounted in a plant room or basement.
Storage heaters
Charge up with heat overnight using cheaper off-peak electricity, then release it gradually during the day. A familiar technology in domestic settings.
Underfloor heating
Heats the floor slab using either electric elements or hot-water pipes buried beneath the surface, providing gentle warmth from below.
