HEATER SIZING GUIDELINES 7.0)
Radiant heaters work like the sun to emit radiant heat directly to the space to increase the comfort of the patio
guests. Suitable applications include patios, porches, outdoor shopping areas and pathways.
The amount of temperature increase in outdoor patio spaces will be dependent on the following factors:
1.
The number of heaters in the space is important to provide good coverage of the area to be heated.
2. Take care not to mount the heaters too low or too close together this can make people directly below the
heaters uncomfortable.
3. It is recommended to use a suitable windbreak to reduce the effects of direct wind on the patio. If an area is
going to be unprotected and is a breezy location then heaters may need to be located closer together. Wind
breaks must be designed to allow fresh air for ventilation.
4. Angling the heaters greater than 30 degrees should be avoided unless the mounting height is low, when the
heaters are angled more than 30 degrees the radiant intensity is lower and will reduce the amount of heat felt
by the guests.
When angle mounting the heater the radiant output will decrease approximately by
following:
Mounting Angle 15 degree 30 degree 45 degree 60 degree
Radiant output reduction 3% 13% 29% 50%
5. It is recommended to place the heaters in the area of greatest heat loss facing into the patio area.
The table below shows minimum area coverage per heater for outdoor patio heating based on a 5 to 10°F (2.8 to
5.6°C) temperature rise.

Note: When sizing the number of heaters to warm the patio, the area coverage given above may not provide the
stated temperature rise under all weather conditions and will be dependent on heater placement. Minimums are
shown as a guideline for human comfort. For more assistance with patio heater sizing and layout please contact
your local Mestek, Inc. representative.
