SunSwitch - installation and design guide The key to successful heating for your terrace area is to install enough heaters of the right power output and type. We include guidelines for mounting heights and the size of area you can expect to be heated on our products pages. > GO TO PRODUCTS PAGES NOW In theory, in perfectly still open air, SunSwitch infra-red heaters should be comfortable to sit under in temperatures as low as 7-8° C. However, air is rarely still and we find that the heaters work very effectively from about 12-13°C. This means your outdoor covers should be productive from early March to late October. In fact, we have seen customers outdoors in the UK under SunSwitches in early January. Mounting your SunSwitch infra-red heaters under an awning or parasol will tend to trap some of the warmth, making them feel warmer (so heat regulation may be required). Similarly, providing protection from the wind, for example with Terrazzo terrace screening will greatly increase comfort levels. Example of an installation Our most popular heater is SunSwitch Weathersafe ™1.3kW . One of these, mounted at a height of 2.2-2.5m will generally serve an area with a table and seating for six to eight people. Typically these heaters are installed along a restaurant front about every 1.5 - 3.0 metres:   Typical installation (SunSwitch 1.3kW Weathersafe): SunSwitch Weathersafe™ is supplied with a mounting bracket and installation instructions. SunSwitch Weathersafe™ can be installed in minutes. Using the bracket provided, it should be positioned out of reach and directed onto the area where warmth is required, with the element horizontal. Sunswitch Weathersafe™ can be installed on walls, rigid fence posts and pergolas, or under parasols and awnings using special brackets. If SunSwitch Weathersafe™ is to be installed outside, as a minimum, a Residual Current Detector and a weatherproof socket should be used. Please note that all electrical installation works outdoors should be in accordance with electrical regulations. Download installation and warranty information provided with this product.
