The Florists^ Review 



March 23. 1922 



houses, it is seldom considered advis- 

 able to install a steam heating system 

 unless as much as 5,000 square feet of 

 glass is to be heated, and under most 

 conditions 10,000 square feet would be 

 a minimum. 



To heat the two houses to 60 degrees 

 when it is 10 degrees below zero, al- 

 though the actual radiation needed will 

 be slightly less than 2,000 square feet, 

 it is best to use a boiler rated at 4,000 

 square feet, or at least the grate should 

 be largo enough for that amount of ra- 

 diation, since lignite is low in heat 

 units. Hence, in order to burn lignite 

 successfully, a boiler should have a 

 grate nearly twice as largo as would 

 be necessary for hard coal. 



To heat the house 24x80, now under 

 construction, run a 2i^-inch flow pipe 

 on each side wall plate and twg others 

 under the puflin posts. Use two 2-inch 

 coils containing four pipes each on the 

 side walls and two coils of two 2-inch 

 pipes each in the walks between the 

 benches. For heating the two houses a 

 grate 36x42 inches will be needed, but 

 if a surplus is needed it may be 36x48 

 inches. 



USING PIPE ON HAND. 



I have mailed you a plan of a small 

 greenhouse, which I wish to heat to 50 

 degrees when the outside temperature is 

 10 degrees below zero. There is enough 

 1%-inch pipe on hand at my place with 

 which to make the returns and I should 

 like to use this pipe if possible. I have 

 a hot water boiler of ample size, but the 

 ports are made for li^-inch pipe. I can 

 have these ports enlarged if necessary, 

 as the boiler is of steel construction. 



J. L. W.— Mo. 



The sketch shows the house to be 

 21x57 feet, with the side walls six feet 

 high, three feet being of concrete 

 and the other three feet being glass. 

 There are four raised benches, two of 

 which are built on the side walls. 



To heat the house to 50 degrees, use 

 three 2-inch flow pipes, placing one on 

 each side wall plate and the other three 

 feet below the ridge. Four 2-inch re- 

 turns will be required in addition to tlic 

 eight 1 '4 -inch returns which will be 

 provided by the pipe now on hand. The 

 1%-inch pipes may bo used for two coils 

 of four pipes each, to be placed either 

 on the side walls or under the side 

 benches. Use the four 2-inch returns in 

 two coils under the middle benches, to 

 be supplied by the middle overhead flow. 

 Provide three 2-incli ports for the flows 

 and the same number for tiie returns.
