Greenhouse heating system is consist of 3 parts, including water boiler machine, heating fans, heating water/air pipes.

Operating Principle

Water in the boiler is heated by electricity. Then, boiled water is pumped out to the heating water pipes by water pump. Passing through the pipeline, then the heating fans blow the hot air into heating air pipe. There are special small holes on the heating air pipe, so the hot air is scattered from the small holes to heat up the whole greenhouse.

The benefit of using this method is that it can efficiently increase indoor temperature while using minimal energy.
