Hard to heat buildings Quartz Halogen infra red heaters are ideal for buildings where it would not be practical or cost-effective to provide comfortable conditions by raising the air temperature. This includes poorly insulated buildings such as conservatories, older workshops, industrial units, halls, churches and marquees. In many such buildings, if you warm the air, for example with convector heaters, the warm air will rise to the ceiling where it is of little use to occupants. In this diagram of a tall building, warm air has risen to the ceiling, leaving occupants literally in the cold. This unpleasant effect can occur in buildings just a few metres high. Moreover, if a building is too 'leaky', any warmed air will simply escape. And, if the building is used only intermittently, it can take hours or even days to take the chill off. The solution is to install SunSwitch quartz halogen infra red. Our heaters work instantly. They provide outstanding comfort and they combine warmth with low, calculable running costs. Quartz Halogen heaters produce short wavelength infra red heat which travels through the air easily and warms you rather like the warmth of the sun (but without any harmful uv rays). This allows you to zone the heat just where you want it. SunSwitch heaters don't warm the air directly, so the air temperature is lower than it would be with other heating methods. This not only saves energy, but it makes for far more comfortable working conditions. In general, we recommend placement of quartz halogen heaters above head height, angled downwards at about 45 degrees. This ensures the infra red rays warm the side of the body. Ideally, heaters should be positioned so that more than one side of the body is warmed at once. We are pleased to offer guidance on the specification and appplication of our products.
