Controlling HWP Patio Heaters

As HWP patio heaters are 100% effective the instant they are switched on, we recommend a control system that will de-energise a heater when heating is not required. This can be achieved by means of a Push Button Timer or a Movement Detector.

Push Button Timer

The BN Thermic TS-3 is a compact, surface mount, weatherproof device conforming to IP66. A simple push button will energise a heater or heaters for a pre-programmed period between 2 minutes and 2 hours. Once this period has elapsed the heating will be automatically switched off until the button is pushed again. The device is vandal resistant and tamperproof meaning only authorised personnel can adjust the time settings. For full details of the TS-3 click here.

The TS-3 has a switching capacity of 16A. It can therefore directly switch a combined load of up to 3kW. Larger loads or 3-phase loads can be switched via a suitably rated contactor.

Movement Sensor

The BN Thermic WH-402 is a compact, surface mount, weatherproof device conforming to IP55. The WH-402 will detect movement in an area up to 12m from its mounting position in a 180° arc. Both distance and angle of detection can be reduced if required. Once movement has been detected, the heating will be switched on. If no further movement is detected within a preprogrammed time period (5 seconds to 18 minutes) the heating will be automatically switched off.

The device is vandal resistant and tamperproof meaning only authorised personnel can adjust the time settings. For full details of the WH-402 clcik here.

The WH-402 has a switching capacity of 16A. It can therefore directly switch a combined load of up to 3kW. Larger loads or 3-phase loads can be switched via a suitably rated contactor.

Dimmer

In specific applications there may be a need to adjust the intensity of the heat output from a HWP patio heater. The BN Thermic VR-1 provides adjustment between 0% and 100% of heater output. It also has a definite ‘click’ to off allowing it to be used as an on/off switch. The VR-1 is a surface mount device but is not suitable for outdoors installation.

The VR-1 has a switching capacity of 13A. It can therefore directly switch a combined load of up to 3kW. For larger loads more than one VR-1 dimmer will be required.

Patio Heater Selection

Use the following diagram and table to select the optimum mounting position. In an exposed location and where mounting height is relatively high, we recommend installing a 2kW or 3kW heater.
