INSTALLINQ PIPE. 



• What size of main feed pipe will be re- 

 quired to supply four 4-iiich flows with 

 hot water? Will it be more convenient 

 and economical to run the feed pipes 

 directly from the boiler, eliminating the 

 one large main between the boiler and 

 the greenhouses, a distance of about 

 twelve feet? C. R. K.— O. 



A good deal depends upon the char- 

 acter of the boiler, as well as on the 

 location of the houses. It often simpli- 

 fies matters if the flow and return pipes 

 for each house are connected directly 

 with the boiler, but in the present case 

 the best thing will be to start from the 

 boiler with two 5-inch flow pipes and, 

 when the first house is reached, take off 

 a 4-inch feed pipe and continue with a 

 4-inch flow to the second house. 



If only one supply pipe is used, it 

 should be not less than a 6-inch pipe, 

 and a still larger pipe might be desirable, 

 depending on the amount of radiation 

 to be supplied. The suggestion that two 

 5-inch flows be used is conditioned upon 

 a 4-inch pipe being suflaciently large for 

 each house. 



PEOVIDINQ FOR ADDITIONS. 



I have two greenhouses, one 9x40 feet 

 and the other 12x45 feet. These houses 

 are four feet high at the eaves and eight 

 feet high at the ridge, making 480 

 square feet of glass in the roof of the 

 first house, and 630 square feet of glass 

 in the second house. These measure- 

 ments also include the glass in one gable 

 in each house. The boiler room is lo- 

 cated at the other end of the houses. 

 What size of boiler and chimney will be 

 required and how mneh pipe will it take 

 to heat these houses with hot water to 

 60 degrees? 



It is my intention later, perhaps, to 

 build an additional house, 24x60 feet. 

 Would it be advisable to install a boiler 

 which is large enough to heat this addi- 

 tional house immediately, or would you 

 put in an extra one later? 



I wish to place all of the pipes under 

 the benches, as these houses are low. 



A. B. M.— Pa. 



To heat the two houses now in use 

 and an additional house, 24x60 feet, to 

 60 degrees in zero weather, a boiler 

 rated at about 1,800 square feet of 

 radiation should be installed, for use 

 with soft coal. 



While it is well to have two boilers, 

 so that one can be held in reserve except 

 in extremely cold weather, the amount 

 of radiation will hardly warrant it at 

 this time. If a fourth house, with 2,000 

 square feet of glass, is likely to be con- 

 structed later, it would be advisable 

 to install at this time a boiler rated 

 at 1,000 square feet, and when the third 

 house is erected a second boiler rated 

 at 1,600 square feet would be suffi- 

 ciently large for four houses. If only 

 these houses are to be built, put in at 

 this time a heater rated at 1,800 square 

 feet. 



The chimney for such a boiler should 

 be twelve inches square inside and thirty 

 to thirty-six feet high. 



To heat the small house to 60 degrees, 

 use two 2%-inch flow pipes and four 

 2-inch returns. In the house twelve feet 

 wide use two 2%-inch flow pipes and six 



The Quickest Water Heater 

 in the World 



The Kroeschell Boiler heats quicker, gives more 

 heat and uses less fuel than any other boiler. 



The efficiency and economy of Kroeschell Boil- 

 ers can in no way be better proved than in the 

 following statements of three big men of the 

 greenhouse trade: 



Charles Totty 



"The Kroeschell Boiler I installed last year usually 

 runs from 10 p. m. to 6 a. m. without attention. I 

 do not have the least trouble to keep temperatures 

 in the coldest weather. The boiler has given entire 

 satisfaction. The Kroeschell is the best boiler we 

 have ever handled." 



Frank Oechslin 



"I have used Kroeschell Boilers ever since I built 

 my first greenhouse. They have always given me 

 the very best satisfaction and I believe them as 

 good boilers as money can buy." 



Chas. McCauley 



"In speaking of the Kroeschell Boiler as an econ- 

 omical greenhouse boiler I cannot say too much. 

 Personally I have had the pleasure or misfortune 

 to fire nearly every make of greenhouse boiler on 

 the market and I can safely say the Kroeschell is 

 the best of them all."
