Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to iDuy, 

 and each article the best in the special 

 field of its adaptation. 



FIVE POUNDS OF FEESSXTBE. 



We are building a new greenhouse 

 and should like to get your advice in 

 regard to heating it. The house will be 

 32x170, running north and south. It 

 will have thirty-six inches of glass in 

 the sides, with two and one-half feet of 

 concrete wall in the sides and ends. 

 The gables will be of glass and will 

 be exposed. The roof pitch will be 

 26*^ degrees. The house will contain 

 four benches. The temperature desired 

 is 50 degrees. The lowest outside tem- 

 perature is about 5 degrees below zero. 

 The steam pressure will be five pounds. 

 Please state how many 1^-inch pipes 

 will be required to heat this house. If 

 one flow pipe is used, what size should 

 it bef If two are used, what should 

 be their size? W. H. K. — Pa. 



With five pounds of pressure, the 

 house can be heated by using one 2%- 

 inch or two 2-inch overhead flows, and 

 ten 1%-inch returns. In case overhead 

 or wall flows are not desired, we would 

 start the coils at the boiler end of the 

 house and use six 1^-inch pipes upon 

 each wall, with the bottom pipe in each 

 arranged to answer as a return for the 

 drip water, if it is sufficiently above 

 the water level to drain quickly; other- 

 wise an additional pipe should be pro- 

 vided as a return pipe for each coil. 



In case bottom heat is desired for the 

 benches, we would advise the use of 

 an overhead flow pipe, which would fa- 

 cilitate the distribution of the returns. 



BETTEB USE OVEBHEAD FLOWS. 



Will you give me some advice about 

 the piping of my greenhouse, which is 

 30x100? The height to the gutters is 

 six feet; to the ridge, sixteen feet. To 

 heat this house I have a 25-horsepower 

 Kewanee horizontal tubular boiler, 

 which stands under the greenhouse. 

 The top of the boiler is level with the 

 greenhouse floor. The firebox is in the 

 shed; so the boiler extends fourteen 

 feet under the greenhouse. There are 



WHEN YOU BUY-QET A KROESCHELL 



'THE BOILER OF UNEQUALED FUEL ECONOMY' 



BUY DIRECT- FACTORY TO USER PRICES 



The Kroeschell 



is making the most 

 wonderful creenhouse 

 heating record in the 

 world. Florists who 

 have used other makes 

 are constantly giving 

 the Kroeschell the 

 highest praise. 



18,468,880 SQ. ft. 

 of glass was eauipped 

 with the Kroeschell 

 Boiler during the past 

 five years. 



The Kroeschell 



is used by hundreds 

 of Florists' Review 

 readers and mighty is 

 their praise. The year 

 of 1915 brought an 

 enormous number of 

 new customers who 

 saw our boilers in 

 operation at other 

 places. We attribute 

 the large sales of this 

 season to the good 

 work the Kroeschell 

 Boiler is doing every- 

 where. 



With our policy—" the customers' interest first"— perfection of construction 

 —factory to user prices— honest and "true blue" boiler ratings— you simply 

 cannot lose.

A Heating Record at 62^ Below Zero 



Has the Kroeschall given entire satisfaction? Yes! Perfect. Our winter 

 temperature ranges as low as 45° below zero. Last winter we had six weeks of 

 steady cold. The maximum temperature at noon 12° below, the minimum tem- 

 perature at 4 a. m. 52° below zero. This was a good test of the heating capacity 

 of a KroeaolieU. Public Park Board, Winnipeg. Man. 



READ WHAT THE USERS SAY: 



The Kroeschell Is Better than Cast Iron 



In 1911 1 purchased a No. 1 Kroeschell Boiler for my uptown greenhouses. At 

 my other range we had a cast iron sectional boiler. In two Tears we cracked two 

 sections. That experience was enough for me. This year I thought I would not 

 take any more chances, so we have just installed another No, 6 Kroeschell Boiler. 

 I believe if the Kroeschell Boilers were known to all, they would use no other.
