Basic Guidelines for Heating Vivaria Reptiles are Ectotherms, that is they heat themselves and regulate their body temperature by means of the environment. They move in and out of hot and cool areas to maintain their preferred temperature. It is therefore important that the vivarium has a suitable temperature gradient for the reptiles to behave naturally. The heater should be placed at one end of the vivarium in a condition that does not heat the whole of the enclosure. In this way the temperature will vary between the hot area near the heater and the cooler areas at ambient temperature. For sophisticated temperature management the thermostat and heater can be fed via a HabiStat Sun or Moon Switch. This will give day/night and seasonal synchronisation. Hot air escaping through the top of the cage HabiStat Size Matters Heaters must be large enough to heat the vivarium to the required temperature. An underrated heater will rarely supply enough heat to reach the temperature set on the HabiStat. Too large a heater will supply so much heat that the HabiStat is continually switching it off. This would lead to poor temperature management and may cause the heater to fail. Background Heater More than one heater may be controlled by either of the channels providing the total load of 300 watts on each one is not exceeded. The ideal heaters to use with this type of thermostat are HabiStat Heat Mats and Strips. Other heaters may also be controlled but light emmiting lamps should be avoided. The best thermostat for this type of device is the HabiStat Dimming Thermostat. Hot spot Heater Heaters will not be switched off until the temperature of the sensors reaches that set. Put all the heaters, background and hot spot, at one end of the cage. Leave one end of the cage unheated. Areas warmer than the set temperature. Mains Perches and hides that allow thermoregulation. Ventilation allowing cool air in. Areas cooler than the set temperature. Build up one end to allow burrowing. The structure must be a matrix of soft and ridged materials which allow the tunnels but not their subsequent collapse. Sensors Cool Temperature gradient Hot Positioning the HabiStat sensors to obtain a thermal gradient. …Using the HabiStat. The HabiStat will control the heater at the level set on the dial and detected at the sensor. The function of the remote sensor is to enable selection of the site at which the temperature can be sampled and controlled. The range of the temperature gradient will be proportional to the distance between the sensor and the heater and the ambient temperature. If the HabiStat is set at a temperature on the dial but the sensor is placed away from the heater there will be areas near the heater that are hotter than the set temperature. Similarly, if the sensor is placed near the heater, there will be areas away from the sensor that are cooler than the set temperature. It should also be noted that as hot air rises, setting the sensor at the top of a vivarium will only maintain the required temperature at that point. A vivarium that houses ground dwelling animals may be too cool if set up in such a way. Place the sensor where the animals are likely to be! Some criteria for controlling the temperature are: • • Ensure that the placement of the sensor is representative of the temperature required, use common sense in choosing the position. Remember that the HabiStat will be most accurate in the middle of its range. Try to use this, rather than the extremes, Text, Illustrations & Design © Euro Rep Ltd. December 1998 to maintain accurate control of temperature. • Although the dial is accurate the temperature should always be checked with a thermometer. It is important to remember that temperature control is critical to the successful keeping of reptiles. HabiStat thermostats use hi-tec sophistication to give precise control and peace of mind.
