2012-10-14 · Greenhouse Heating Central Heating Systems •System –one or more boilers in a central location –distribution pipes piping steam or hot water into the greenhouse--almost all are hot water today –boiler components + heat distribution system = $2.50 to $3.25/ft2 of greenhouse floor area –more expensive to install than unit heaters, but can burn cheaper fuels and require less maintenance ($)

Floor heating is another method to heat the greenhouse with hot water. With this method, pipes are placed in the ground under a layer of concrete, gravel, sand or soil. Heating pipes form loops around the entire surface of the greenhouse. The water temperature can be up to 104˚F (40˚C).

When a central heating system is used to produce hot water or steam, grooved steel, copper, or PVC pipes can be used to distribute the heat energy throughout the greenhouse. Hot water systems typically require more piping and circulating pumps; steam systems require fewer pipes because steam provides more BTUs per linear foot of pipe than hot

Especially in vegetable crops, the tube rail heating system has been widely applied as it has a significant logistical advantage. Another common hot-water circuit in the vegetable production is the grow tube.

Hydronic heating is the use of water as a heat transfer medium in heating systems, using a boiler to heat water and a pump to circulate the hot water in rubber tubes that are either buried underground for field growing, embedded in concrete for radiant floor heating, or installed in greenhouse bench systems.

GREENHOUSE HEATING SYSTEM BASICSThe most economical option for heating greenhouses, forced air unit heaters are easy to install and provide low initial cost and high efficiency. Among the most fuel efficient heating options, hot water is available as in-floor, under bench, and perimeter configurations.
