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 Review 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 buy, 

 and each article the best in the speeial 

 fi«ld of ita adaptation. 



WILL ADD ONE HOUSE. 



I now have an opportunity to buy 

 2-inch and 2% -inch pipe for less money 

 than if I wait till laten I should 

 like to know, therefore, how many 

 2%-inch flows and 2-inch returns will 

 be needed to heat a greenhouse 20x50. 

 It will run east and west and will be 

 connected to the south side of the pres- 

 ent house, which is of the same dimen- 

 sions. The boiler room is at the west 

 end; the east end will be exposed. The 

 south wall will consist of three feet of 

 tile and three feet of glass. I want 

 a temperature of 60 degrees in zero 

 weather. I should like to put the re- 

 turns on the side walls, connecting the 

 returns to manifolds, if this arrange- 

 ment is advisable. The boiler is an 

 upright tubular, with a grate thirty- 

 six inches in diameter. The boiler 

 now has one 4-inch flow and two 2-inch 

 flows, and the same returns. Will these 

 be sufficient for both houses, or would 

 you advise having another 4-inch flow 

 and 4-inch return put in the boiler? 



O. B. - 



To heat a house 20x50, with one ex- 

 posed side wall containing three feet 

 of glass, we would use two 2*4 -inch 

 flow pipes and twelve 2-inch returns. 

 If the top of the boiler is below the 

 level of the returns, we would carry 

 one flow pipe upon each side plate; 

 otherwise they should be placed about 

 two feet below the ridge or under the 

 purlins. If the flow pipes are given a 

 slight fall, the expansion tank may be 

 connected with the highest part of the 

 system and there will be no occasion 

 for using air valves. The return pipes 

 may be placed in coils on the side 

 walls. Especially if the outer wall is 

 much exposed to cold winds, we would 

 place seven returns on this wall and 

 five on the inner wall, connecting them 

 by means of manifolds. 



While it is not possible to judge the 

 capacity of a boiler accurately by 

 means of its grate area, we would ex- 

 pect to heat four houses 20x50 to 60

Now last winter the temperature dropped for two days to 32' 

 below zero here — everybody thought we would freeze In — now listen ! 

 We fired on half draft and kept the houses steadfast 52° with ease. 

 I use Mine Run Smokeless Coal at $2.75 per ton, F. O. B. here. Noth- 

 ing else than Kroeschell boilers for me ; my experience with others 

 tell me so. Let anyone ask me in regard to your boilers, the answer 

 will be — "Buy Kroeschell Boilers."

Replying to your letter of the 16th, wish to state that we have 

 completed the installing of our Heating System, and have given same 

 a thorough trial and we are very well pleased with the results. Quite 

 a number of Florists of our city have visited our Greenhouses, and are 

 very much impressed with our Heating Plant. 



Thanking you very much for the promptness that you have given 

 our order, and rest assured should we need anything in the heating line 

 in the future, that we certainly shall not forget "Kroeschell Bros.," 

 we are,
