The calculator provides an indicative heating requirement based on room dimensions, ceiling height and building type. It is designed to provide a useful starting point for infrared heating system sizing. Actual heat loss can also be affected by insulation, glazing, ventilation, construction and local site conditions.

Yes. The calculator uses room volume rather than floor area alone, so ceiling height forms part of the heating calculation. This is particularly important for rooms with unusually high ceilings, commercial premises, churches and other large spaces.

Once the room heating requirement has been calculated and you select an infrared heater model, the tool automatically compares the product wattage with the required output and recommends a quantity. You can also manually adjust the quantity if your proposed design requires a different arrangement.

The calculator compares the installed heater output with the calculated room requirement. If the selected quantity is too low, a clear warning shows the wattage shortfall and asks you to increase the quantity or choose a higher-output heater. Underpowered projects cannot be added using the complete-project basket button.

A correctly sized wall-mounted infrared heating system can provide the required heating output for a whole room. However, the radiant distribution pattern differs from a centrally positioned ceiling panel because the heat originates from one side of the room. Heater positioning is therefore important for achieving balanced comfort.

Yes. Once every room has complete dimensions, a selected heater and sufficient installed output, the complete project can be added to the basket in one action. Duplicate products are combined, calculated quantities are retained and recommended thermostatic controls are included where required.

Positioning depends on the heater type, room layout and intended use. Ceiling panels can provide broad downward radiant coverage, while wall panels should normally be positioned where their front surface has a clear view of the occupied area. Directional bar heaters may require more specific aiming and mounting positions.

Infrared heating systems should be controlled thermostatically. Where the selected heater does not include a built-in thermostat, the calculator can recommend additional thermostatic controls. Individual room zoning can improve comfort and allow different spaces to operate at different temperatures and schedules.

Yes. You can add multiple rooms to the same project. Each room can have different dimensions, heater ranges, models and quantities. The project summary combines the required wattage, installed heating output and estimated cost.

The PDF proposal includes the project summary, room-by-room calculations, selected infrared heaters, quantities, installed output, estimated costs and any optional client or project details entered. The original product datasheets for the selected heaters are automatically appended to the proposal.
