Hot water from the boiler is circulated through a heat exchanger to heat the water in the buffer tank. At night when heat is needed, the hot water from the tank is circulated through the heat pipes or unit heaters in the greenhouse. This system will allow a smaller boiler to be installed as it can be operated continuously day and night.

Some people prefer boilers because they can set their thermostat at a lower temperature and the radiant heat makes the room feel warmer than the actual air temperature. Others say boilers provide more balanced heat throughout the home during the winter months. 3. What are the most important things to know about your boiler heating system? Here

Steam Heating System. A steam heating system needs a boiler, valves, traps and other controls depending upon the size and type of boiler used. Steam provides rapid heating and cooling of the steam lines and usually less pipe is needed. Lines may be smooth or finned, and about l/3 of the heat should be overhead and about 2/3 along the side walls.

Effective and economical greenhouse heating is the union of an appropriate heat source and an efficient heat distribution system. The best greenhouse heat source in the world is useless if the heat cannot be transferred to the plant environment. Likewise, an efficient heat distribution system is useless if an adequate heat source is not used.

Greenhouse Size – If you have a small operation, an outdoor furnace that burns cord wood will easily heat one or two small buildings. If filling a stove on a daily basis is not for you or if you have multiple buildings to heat, you may want to consider a biomass wood chip boiler as your heat source.
