Heating A Greenhouse

The challenge to keep a greenhouse frost-free:

Phoenix Greenhouse HeaterPhoenix Greenhouse Heater

The temperature must remain above 32°F even in the corners. If the current of air does not reach there, then the temperature on the heater has to be really high, however, then a large proportion of the warmth goes up into the gable of the greenhouse, where it is not needed, while the corners may still dip down to minus temperatures.

This is an unsatisfactory state of affairs because heating energy is being wasted. In addition, there may be a significant temperature difference between when the heater switches on and off, especially with cheaper thermostats. This means if the thermostat has a switching differential of, for example, 43°F, then the greenhouse has to be heated up to 47°F if it is not to fall below the frost-free limit of 36°F before the heating switches on again automatically (see diagram).

These heaters avoid this unnecessary heating up by keeping the switching differential to a minimum, as can be seen from Diagram. This results in significant energy savings. This is why we, as greenhouse specialists, have developed a range of heaters that offer important advantages: High ventilation rate up to 14832.16 ft (460 m3 /h), The fan setting. By using the fan setting, all the air in the greenhouse can be circulated even in the summer season. With the window open and the fan on, the greenhouse can be cooled down. Air circulation in the summer is also necessary for the pollination of many flowers.



This heat-loss Btu calculator will help you decide on the size of the heater needed for your greenhouse. First, you need to know the Surface Area of your greenhouse. Use our Greenhouse Surface Area Calculator to find the total square feet of the exposed surface area of your greenhouse. Then, use our Greenhouse Heater BTU Calculator to find out the minimum heater BTU rating to keep your greenhouse at an inside desired temperature during the winter.
