placing the larger number on the side 

 most exposed. All of the returns may 

 be on the side walls, but if bottom heat 

 is desired a third 2-inch pipe may be 

 dropped down and connected with three 

 of the returns. For the other house the 

 same method may be used, but the num- 

 ber of returns should be reduced one- 

 third. 



DEPTH OF BOILER PIT. 



We are building a greenhouse, 24x100, 

 for carnations and pot plants. The 

 bouse runs east and west. The boiler 

 shed is the full width of the house and 

 is at the west end. The sides are five 

 feet high, with sixteen inches of glass, 

 and will be finished with cement stucco 

 on board siding. The ridge will be 

 eleven feet eight inches high. We wish 

 to heat with hot water and have pur- 

 chased a second-hand, seven-section 

 Ideal boiler, with a fire-box 32x48 

 inches. We can conveniently set the 

 boiler two feet below the level of the 

 walks. Will it be necessary to set it 

 deeper than that? Would you advise 

 us to use a generator? Please inform 

 us as to the best arrangement of the 

 piping for this house, to heat it to 55 

 degrees. In this part of Michigan the 

 outside temperature sometimes drops to 

 20 degrees below zero. D. & H. 



Unless the boiler can be set low 

 enough to bring the top of the fire-pot 

 as low as the coils, a generator should 

 be used. If the top of the boiler is as 

 low as the floor of the greenhouse there 

 will be less occasion, for using a genera- 

 tor, although a considerable reduction 

 in the amount of radiation can be made 

 if a generator is used.

To furnish the needed radiation with- 

 out a generator, use three 2 1^ -inch 

 flows, one of which may be under the 

 ridge and the others on the plates, and 

 nine 2-inch return pipes, connecting 

 three of these with each flow pipe. If 

 a generator is used, only six returns 



will be required in addition to the throe 

 21^-inch flow pipes, but the economy 

 of the heating will not be so graat w^'" 

 the water is under pressure as iin ^d 

 open tank system. The boiler described 

 should heat two houses like the on*' 

 under construction. ' '
