heat besides the small one, and what sys- 

 tem of piping would you advise? There 

 will be a half bench on each outside and 

 two full benches in the center. The 

 grate surface of the heater is about 19x 

 29 inches. E. & B. 



No! The boiler is not large enough 

 to carry one-half the proposed new house 

 in addition to the one you already have. 

 The new house can be piped in the same 

 fashion as the one you already have, 

 which you say gives good service. The 

 new house should have a 3-inch flow 

 pipe and eleven lines of 2-inch pipe, or 

 fourteen lines of l^^-inch pipe installed 

 as returns. 



The boiler has a rated capacity for 700 

 feet of radiation, while the two houses 

 should have 1,050 feet, and the heater 

 should have a rated capacity for at least 

 1,200 feet to be on the safe side.

FACTORS IN HEATING PROBLEM. 



I note in his answer to A. E., your 

 heating engineer, L. C. C, says glass 

 surface is only one of the factors in a 

 heating problem. He was given the tem- 

 perature desired, and the outdoor tem- 

 perature. Probably he allowed for only 

 moderately well built houses, but I would 

 like to know what are the other factors 

 in a heating problem. Perhaps all of us 

 are overlooking essential details for lack 

 of expert knowledge. H. O. 



For the satisfaction of my friend H. 

 O., I wish to say that glass area is, as 

 a rule, only a part of the exposure of 

 the ordinary greenhouse. In calculating 

 heating requirements we consider the 

 total surface exposed, sides and ends as 

 well as roof. The question of type of 

 construction also enters; i. e., whether 

 the houses are connected, ridge and fur- 

 row, or isolated; the character of heat 

 to be used, and also the climate in which 

 the houses are located. This will ex- 

 plain why it has been our custom to re- 

 quest data in regard to the length, 

 height of side walls, height to ridge, tem- 

 perature desired, minimum outdoor tem- 

 perature, the type of construction and 

 the exposure. L. C. C

TWO HOUSES AND DWELLING. 



I wish to heat two even-span houses, 

 one 20x50, with brick walls four feet 

 high and rafters twelve feet long, the 

 other 20x30, with walls four and one- 

 half feet high and rafters twelve feet 

 long. In connection with these two 

 houses I wish to heat a dwelling, one 

 story, 25x50, containing three rooms and 

 a hall only that will need to be heated. 



I have a twenty horse-power tubular 

 steam boiler, thirty-three inches in diam- 

 eter, containing twenty-eight 3-ineh flues 

 eight feet long. The boiler has a dome 

 and the flow has 4-inch taps at the dome. 

 How deep should I dig the boiler-pit for 

 a hot water system? I have about 500 

 feet of 21/^ -inch pipe, 800 feet of 2-inch, 

 three 2-inch valves, three 2%-inch valves 

 and one 3% or 4^ -inch valve. How 

 many radiators and what number of sec- 

 tions will the house require and the num- 

 ber of flows and returns for the green- 

 houses? The boiler is just back of the 

 20x30 greenhouse. Would you advise
