Yes, and it is one of the easiest ways to cut your heating bill. Zoning means heating only the part of the building that is in use: the nave for Sunday services, the chancel for a midweek prayer group, the vestry for a PCC meeting. You heat the zone, not the whole church.
With gas convection heating you can only zone effectively by physically separating spaces, because warm air drifts wherever it likes. Radiant infrared systems zone without walls. Each heater or group of heaters serves a defined area, and you switch on only the zones you need. A sports hall does this for weekend squash courts; a church does it for the chancel on a Wednesday evening.
Modern control systems make this straightforward. Set a target temperature per zone, and the heaters run at full power to reach it, then dim to maintain it. Some systems offer remote control, so the churchwarden can set the heating from a laptop before leaving home. Zoning is not a luxury add-on. It should be the starting point of any church heating scheme.
