Properly sizing a greenhouse heating system is crucial for increasing heating capacity and maintaining the perfect temperatures year-round. Sizing a greenhouse heating system only requires growers to make several measurements and a few calculations. Once the numbers are crunched, growers will be well on their way to sufficiently heating their operation.
Efficiency ratings are of utmost importance in greenhouse temperature control, whether it’s for an indoor heater, a heat pump or an air conditioner. An efficient, properly sized greenhouse heater delivers uniform heating to the plant canopy. This consistency in temperature promotes strong, rapid plant growth.
SIZING A GREENHOUSE HEATING SYSTEM
Heaters are measured by their output in BTUH (British Thermal Units per Hour) as opposed to their physical size. A heater that is larger in size does not automatically mean more heat output. BTUH reflects the size of an area that a heater can keep warm each hour, and growers have to find a heater that can provide the right BTU per square foot ratio.
This ratio will help growers keep their greenhouse within an optimal temperature range for the specific crops they are producing. For example, an operation that’s primarily growing tomatoes will want to choose a heater that easily maintains temperatures between 60 and 80 degrees Fahrenheit.
To determine the appropriate heater size, growers can follow this step by step guide to calculate the amount of BTUH a heater needs to generate for their greenhouse.
