enough for the six houses. The boiler 

 is set ten feet below the floor of the 

 greenhouses. S. H. B. — :Ky. 



For a temperature of 60 degrees, in 

 a house ten feet wide, three 3-inch 

 pipes will be required and an additional 

 pipe should be used in the outer house, 

 which has three and one-half feet ad- 

 ditional glass. It would be preferable, 

 however, to run a 2% -inch flow pipe 

 on each wall and connect each of them 

 with a coil of two 2-inch returns, using 

 three returns on the north wall. To 

 heat the 7-foot violet house, two S-inch 

 returns would suffice. These may be 

 connected with one of the flows in the 

 south house. 



While a 14-horsepower boiler might 

 answer for heating the houses, I would 

 prefer a boiler rated for at least 

 twenty horsepower. 



OONKECT DmECTLT TO BOILER. 



Please tell us how many runs of 2- 

 inch pipe will be needed to heat our 

 greenhouse, which is 20x50. Also state 

 where to locate the pipes to get the 

 best results. We want a temperature 

 of 55 to 60 degrees in zero weather. 

 The house runs east and west. One side 

 wall is fifty-four inches high; the other 

 is thirty-flve inches high. Both these 

 walls are concrete, except that there 

 are sixteen inches of glass on the 

 south side. One end of the house is 

 glass above the eaves; the other end 

 adjoins our residence. The height from 

 floor to gable is twelve feet. 



We have another greenhouse, and 

 both it and the residence are heated 

 with hot water. The hot water boiler 

 is in the basement, under the dwelling. 

 Can we connect the new piping to the 

 pipes that heat the other greenhouse, 

 or shall we connect at the boiler? The 

 boiler has only two more connections 

 for flows and two for returns. It is a 

 5-8ection hot water boiler. 



E. E. K. & S,— Kan. 



For heating a greenhouse 20x50 to 

 60 degrees, I would use three 2-inch 

 flow pipes and twelve 2-inch returns. 

 It does not seem to be clear whether 

 one or two boilers will be used, but if 

 both greenhouses and the dwelling are 

 to be heated from one boiler, I would 

 certainly connect the flow and return 

 pipes in the house 20x50 directly with 

 the boiler. The size of the boiler ports 

 is not given, but if they are smaller 

 than 2^-inch, I would still use that 

 size of pipe for the main flow and re- 

 turn pipes and reduce them at the boiler 

 to 2-inch. 



Place one of the flow pipes upon 

 each side wall plate and the other un- 

 der the ridge, with four of the returns 

 on the walls underneath, or under the 

 side benches, and the others under the 

 middle bench. 



PIPING ONE DETACHED HOUSE. 



I should like to have you figure the 

 heating on house No. 1, as shown on 

 the enclosed sketch. You will notice 

 that the house to be heated is separated 

 from the other house by an open space 

 of twelve feet. Please state the right 

 number and size of flows and returns 

 and describe the most efficient arrange- 

 ment. Should all the returns be placed 

 on the wall posts f Which system would

It has made thousands of dollars for many flo- 

 rists and may do as much for you. Your plants 

 must have certain, steady temperature to do their 

 best. Use this thermometer and you will know 

 whether they are getting what they need. It 

 leaves a written record under lock and key.
