TheWcekly Florists' Review. 



February 23, 1911. 



and the side walls, which are glass, are 

 two feet high above ground. Please 

 tell me what size of boiler and what 

 amount of piping would be required to 

 heat these houses to 50 degrees. Give 

 me directions for the piping, as the 

 present piping is not satisfactory and 

 the boiler is too small. E. L. H. 



The method of heating is net stated, 

 but for such small houses it is generally 

 better to heat with hot water. The 

 boiler should have a rating for about 

 600 square feet of radiating surface, 

 and a 3-inch main floor, with a return 

 of the same size, will answer. 



To heat the larger house, take off 

 two 2%-inch flow pipes, to be carried 

 on the plates, and connect each with a 

 coil containing five 2-inch returns. In 

 the other house use one 2^ -inch flow 

 and six 2-inch returns. Eun the flow 

 pipes with just enough fall to keep the 

 air from pocketing, and also give the 

 returns a slight fall. Unless the re- 

 turns are well above the top of the 

 boiler, keep them as high on the walls 

 as possible. 



A RANGE OF FOUR HOUSES. 



Please give me information as to the 

 proper amount of 2-inch pipes and the 

 .best way of arranging them, to heat 

 the following houses to a temperature 

 of 57 to 65 degrees. In this section of 

 IsTew York state we occasionally get 

 an outside temperature of 10 degrees 

 below zero. There are four houses, of 

 the following dimensions: Three of 

 them are each 18x100, eight and one- 

 half feet to the ridge and four feet to 

 the eaves, with fourteen inches lof 

 glass in the sides, and the ends partly 

 glass; the walls and the divisions be- 

 tween the houses are of 4-inch con- 

 crete. The other house is 10x100 and 

 eight feet four inches to the ridge, 

 with side walls of 4-inch concrete and 

 the ends partly glass. The houses run 

 north and south and the north ends 

 are protected by a workshop and shed. 

 There are three benches, two and one- 

 half feet high, in each of the 18-foot 

 houses, and two in the 10-foot house. 

 G. M. B. 



For the houses with a width of 

 eighteen feet it will be advisable to 

 use three 2% -inch flow pipes and nine 

 2-inch returns. Hun one of the flows 

 under the ridge and the others on the 

 plates. Place the returns in coils of 

 three pipes each, under the benches. 

 Run all of the pipes with a slight fall. 

 In the house ten feet wide, two 2%-inch 

 flow pipes and six 2-inch returns will be 

 required. In this house place the flows 

 on the plates and the returns in coils 

 of three pipes each, under the benches.
