Greenhouse Heating 



Subscribers are invited to write the 

 editor of this department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often 

 helpful, also, to have a sketch showing 

 the location of the houses. 



FROM STEAM TO HOT WATER. 



My greenhouse is 21 x 90 feet, and 

 has "three feet of glass and three feet 

 of wood in the sides. At this time 1 

 heat it with steam and have plenty of 

 boiler capacity. The boiler and potting 

 shed is at the west end of the house and 

 is well protected. I want to change 

 to hot water heat. 1 have 1,000 feet of 

 lV4-inch and 200 feet of 2-incli pipe. 

 How many 2-inch mains Avill be needed 

 and how liiany H/i-inch returns? I want 

 to heat the house to a temperature of 

 ")() (Icgrces wlieii it is 10 l)elow zero out- 

 side. I"'- K- — 1^0. 



To heat the house .Icscribed al)0ve, it 

 would l)e advisable to use three 2^2- 

 inch and two 2-inch flow pipes, placing 

 the 2-iiich flows on tlie side wall plates, 

 with a 2i/j-in('li flow pii)e on each purlin 

 and the other three feet lielow the ridge. 

 While it is preferable to use 2-inch pipe 

 for the returns, the li/i-inch pipe on 

 hand may Ite^used in connection with a 

 circulator. fJn addition to the eleven 

 lines of 1 '4 -inch return ])ipes in the 

 coils, it woifld be well to use four 2-inch 

 returns. In order that a free circula- 

 tion may be secured, it is important 

 tliat the returns he higher than the top 

 of the lioiler. although, with overhead 

 flow ])i])es and using a circulator, fairly 

 good results may be secured if the 

 lower end of the returns is two or three 

 feet ab()\ e the grate. 



FOR DWELLING AND BEDS. 



1 have no greenhouse, but I have one 

 and one-lialf acres of laud laid out in 

 beds six feet wide. T use 3x6-foot saslies 

 on some of the beds. I may build a 

 greenhouse later. Likewise, I have a 

 large l.'i-room residence on this land, 

 with a cellar under tlie entire building. 

 I want to get as serviceable and inex- 

 jiensive a heating system as possible to 

 install in the l)asement of the residence. 

 Then I plan to extend pipes to my 



Battery of Kroeschell Hisrh Pressure Return Tubular Steam Boilers 

 with Suspended Setting. 



KROESCHELL FUEL 

 ECONOMY 



Higher production efficiency with lower 

 costs is what every business is striving 

 for nowadays. To the greenhouse man 

 this means more and better stock with 

 less operating expenses. 



Coal is the big item for the grower. 

 Each ton of coal he can save adds great- 

 ly to his profits. 



For fuel economy there is no better 

 boiler than the Kroeschell High Pressure 

 Steam Boiler. It burns the lowest grades 

 of coal, requires less, and gives more 

 heat. 



Kroeschell Boilers can be depended on 

 at all times. They insure conditions 

 necessary for raising the highest grade 

 stock. The profits of hundreds of grow- 

 ers have been increased by raising bet- 

 ter stock with less fuel in houses heated 

 by Kroeschell Boilers.
