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 infor- 

 mation is desired regarding the capacity 

 of boilers, 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 arrangement of the green- 

 houses. It is often helpful, also, to 

 have a sketch showing the location of 

 the houses. 



RUNNING PIPE TO DWELLING. 



I have been heating my dwelling with 

 a small hot water boiler located in the 

 greenhouse boiler pit, but it is not large 

 enough, and I would like to get a new 

 one, so that I can heat one of the green- 

 houses also. The boiler is not high, and 

 the line runs gradually from the top of 

 the boiler to the top of the cellar of the 

 dwelling. 



If I get a larger boiler, I shall have 

 to carry the line overhead a distance 

 of 130 feet. To get into the cellar of 

 the dwelling at the end of the 130 feet, I 

 shall have to drop down about 5 feet. 

 Because of the sewer I can not make 

 the boiler pit any deeper. Will the hot 

 water rise and heat the dwellingt The 

 present line is 3-inch, and the expan- 

 sion tank is on the second floor. 



J. E. S.— Pa. 



While the drop in the flow pipe re- 

 quired to get it into the cellar is not 

 desirable, it will not greatly hinder the 

 -circulation, especially if the flow can 

 be run with a slight rise from the boiler. 

 This need not be more than one-half 

 inch in ten feet, or just enough to allow 

 the air to escape from the pipe. 



It will of course be necessary to pro- 

 vide some kind of vent to free the pipe 

 from air. An ordinary air cock will re- 

 quire frequent attention. The air will 

 take care of itself if a small vent pipe 

 is run from the highest part of the flow, 

 just before it drops, to the level of the 

 expansion tank, but care should be tak- 

 en to allow for "boiling over." 



Another plan would be to run a vent 

 pipe, with a pet cock at the end, to the 

 kitchen, where it could be occasionally 

 tested for air. 



HEATING SMALL HOUSE. 



I should like your advice on heating a 

 house 28x80 feet, which is six feet to 

 the gutter and has eighteen inches of 

 glass in the north wall and twenty- 

 seven inches in the south wall. The 

 east end and gable are glass; the west 

 end is covered by the service shed. The 

 house is about thirteen feet to the ridge. 

 I shall use hot water heat and wish to 

 maintain a temperature of 50 degrees 

 when it is zero outside. 



I have enough 2-inch pipe to run the 

 length of the house six times, one house 

 length of 4-inch and the rest 1%-inch. 

 The 4-inch was formerly used for the 

 flow. Would you buy 2^-inch pipe for 

 flows or use the 2-inch and the 1%-inch 

 for the returns! I have also one house 

 length of 21^-inch. L. E. S.— Mich. 



Under ordinary conditions, we pre- 

 fer to use overhead flows for hot water 

 systems in greenhouses, and do not con-

Neither in the East or West nor the North or South has any other 

 malce off Boiler ever equaled the performance off the Kroeschell. 

 Installed for 3,974,605 square ffeet of glass in 1916-1917.

The Kroaschell has proven its worth 

 in many of the largest establish- 

 ments in this country. It has fre- 

 quently been installed by the most 

 careful buyers in competition with 

 all other makes of boilers. 



Greenhouse owners like the Kroe- 

 schell because of its extreme sim- 

 plicity and freedom from trouble. 

 As a fuel saver it pays its own way 

 — it can be operated with the cheap- 

 est grade of fuel. 



Every customer immensely satisfied. The high 

 efficiency and low cost of operation make the 

 Kroeschell the best of all boilers for florists' use.

EXPRESSIONS FROM MEN WHO KNOW BOILERS 



Ni Niri Cast Inn Bcilers 



I have used several different 

 makes of boilers but none I like as 

 well as yours. 



The Kroeschell is easier to Are, 

 takes less coal and water circulates 

 quicker than any other boiler. 



I have used two different makes 

 of sectional boilers — ^ne mora cast 

 Iron boilers for ns. 



[Signed] Mr. . Mich. 



Kneschell Replaces Cast Iron 



The Kroeschell has replaced three 

 cast iron sectional boilers, and It 

 certainly has (iven entire satisfac- 

 tion. 



It only takes a few words to ex- 

 press the good Quality of your boil- 

 ers and they are as follews: "Of 

 all firms handling bolters and ad- 

 vertising them truthfully, the party 

 buying a boiler would have to get 

 the Kroeschell, as you are certainly 

 advertising nothing but facts." 



[Signed] Mr. , N. T. 



KROESCHELL BOILERS will put high 

 temperatures Into yeur heating lines.
