Start with how your building is used. A church open for one service a week needs a system that responds quickly and does not waste energy heating an empty building. A community hub open five days a week needs steady background warmth. The two call for very different systems.
Next, consider the building itself. Ceiling height matters: convection heating is inefficient in a tall nave because warm air rises away from the congregation. A listed interior limits where equipment can go. Whether you have a gas supply, the condition of your electrics, and whether the floor is likely to be lifted all narrow the options.
Then look at cost across the whole life of the system, not just the installation price. A cheap system with high running costs may cost more over ten years than a more expensive one that is cheaper to run. Factor in maintenance, fuel price trends, and whether the system qualifies for grants.
