The Complete Guide to Efficient Church Heating: What Every Church Should Know
Heating churches and heritage buildings presents challenges that few modern buildings face. Large internal volumes, high ceilings, intermittent use, and restrictions on structural alterations make traditional heating systems inefficient, costly, and sometimes damaging. This guide explains why infrared heating has become the preferred solution for churches across the UK and how it delivers comfort, efficiency, and long-term preservation.
At Infrared Heating Supplies, we work with churches of all sizes, from small rural chapels to large listed buildings, helping them modernise heating systems without compromising heritage or budget. This guide brings together practical insights, cost considerations, and real-world lessons to help churches make informed decisions.

Why Heating Churches Is So Difficult
Churches are unlike modern residential or commercial buildings. Most were designed centuries before modern heating existed, with architecture focused on openness, height, and acoustics rather than heat retention.
- Large internal air volumes that are expensive to heat
- High ceilings where warm air rises and is lost
- Intermittent use rather than continuous occupation
- Restrictions on altering walls, floors, and ceilings
- Sensitive materials such as timber, plaster, stone, and organs
Traditional air-based heating systems struggle in these conditions. They rely on warming large volumes of air, require long warm-up times, and often create uneven temperatures. This leads to high energy bills and poor comfort for congregations.
Why Churches Are Moving Away from Traditional Heating
Gas boilers, convection radiators, and warm air systems were never designed for buildings used once or twice a week. In churches, they often need to be switched on hours before a service to achieve acceptable temperatures.
Even then, much of the heat rises into the roof space, leaving seating areas cold. Rapid heating and cooling cycles can also cause condensation, which damages historic fabric over time.
We explore these issues in detail in our guide: The Difference Between Infrared and Traditional Heating in Churches
How Infrared Heating Works in Churches
Infrared heating operates on a fundamentally different principle. Instead of heating air, infrared heaters emit radiant heat that warms people and solid surfaces directly.
This approach mirrors how the sun provides warmth. Even on a cold day, you feel warm when standing in sunlight because the heat is absorbed directly by your body and surroundings.
In churches, this delivers several key benefits:
- Comfort is felt quickly without long pre-heating times
- Heat remains at seating level rather than rising
- Air movement is minimised, reducing draughts
- Humidity levels remain more stable
Because infrared does not rely on circulating air, it avoids many of the inefficiencies that plague traditional systems in large, open spaces.
Heating a Church Without Causing Damage
One of the biggest concerns for church authorities is protecting the building itself. Many historic churches contain materials that are sensitive to rapid temperature and humidity changes.
Traditional convection heating can cause:
- Condensation on cold stone surfaces
- Drying and cracking of timber
- Damage to pipe organs and furnishings
- Mould growth in under-heated areas
Infrared heating gently warms surfaces, reducing condensation risk and helping stabilise moisture levels. This makes it particularly suitable for listed and heritage buildings.

Infrared Heating for High Ceilings
High ceilings are one of the biggest sources of heat loss in churches. Warm air naturally rises, which means traditional systems spend much of their energy heating unused roof space.
Infrared heating avoids this problem entirely by delivering warmth directly to occupants and surfaces. The height of the building becomes far less relevant.
Correct positioning is essential, however. Heaters must be sized and placed to ensure even coverage across seating areas.

Choosing the Right Infrared Heater for Churches and Public Buildings
Not all infrared heaters are suitable for churches. Public buildings require systems that are safe, discreet, and powerful enough to handle large spaces.
Key considerations include:
- Correct wattage sizing for seating zones
- Ceiling or high-wall mounting for safety
- Compliance with public building regulations
- Zoning and control flexibility

How Much Does It Cost to Heat a Church with Infrared?
Cost is often the deciding factor. Many churches assume modern heating systems are unaffordable, but infrared heating often delivers one of the best returns on investment.
Infrared systems:
- Require no pipework or boilers
- Can be installed incrementally
- Use less energy for intermittent heating
- Have minimal maintenance costs
Running costs are reduced because heating is only used when required and only where people are present.

Avoiding Common Church Heating Mistakes
Many churches experience problems after installing new heating systems due to poor design decisions.
Common mistakes include:
- Oversizing systems based on volume rather than occupancy
- Heating unused areas
- Choosing air-based systems for high ceilings
- Ignoring zoning and control

The Environmental Case for Infrared Heating
Many churches are now committed to sustainability through initiatives such as Eco Church and diocesan net-zero targets.
Infrared heating supports these goals by:
- Eliminating fossil fuel dependency
- Reducing overall energy consumption
- Working well with renewable electricity
- Lowering long-term carbon emissions
