Church heating in the Diocese of Portsmouth

The Diocese of Portsmouth covers South-east Hampshire, the Isle of Wight and part of south-east Surrey and has around 170 Church of England churches. The cathedral is in Portsmouth.

Heating decisions in the diocese go through the Diocesan Advisory Committee (DAC), which advises on changes to church buildings including heating installations. Any significant heating work in a church typically needs a faculty, the Church of England's equivalent of planning permission for church buildings.

Churches across the diocese range from small rural parishes to large town churches, each with different heating needs. The right system depends on building size, construction, usage patterns and budget. We can help you work through the options and identify what suits your church.

Heating options

Which system suits a church depends on the building, the budget and how the space is used.

Heating type

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.

Read the guide →Heating type

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.

Read the guide →Heating type

Electric panel heaters

Wall-mounted convection heaters that warm the air around them using electric elements. Simple to install and familiar to most people.

Read the guide →Heating type

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.

Read the guide →Heating type

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.

Read the guide →Heating type

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.

Read the guide →Heating type

Pew heaters

Electric heaters mounted beneath or behind pews, warming the congregation directly through convection or infrared radiation. Discreet and silent.

Read the guide →Heating type

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.

Read the guide →Heating type

Underfloor heating

Heats the floor slab using either electric elements or hot-water pipes buried beneath the surface, providing gentle warmth from below.
