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 special 

 field of its adaptation. 



HEAT FROM EXHAUST STEAM. 



We have a heating problem which 

 we wish to submit and we shall appre- 

 ciate an answer from your expert as 

 early as possible. Our greenhouses 

 adjoin an electric light plant. The 

 exhaust steam from this plant would 

 heat our entire range, which consists 

 of four houses, each 26x150 and seven 

 feet high to the eaves. The electric 

 light company wishes to meter this 

 steam to us. What rate would have to 

 be paid for the exhaust steam to make 

 it cost practically the same as with our 

 present steam heating system? 



D. B. G.— S. D. 



The comparative cost of heating 

 greenhouses with exhaust steam, as pro- 

 posed, will depend largely, of course, 

 upon the price of coal. In most cases 

 the rates have a sliding scale, per thou- 

 sand pounds of condensed water, of 

 from 50 to 60 cents when coal costs 

 $2.50 per ton to 90 cents when the 

 same coal is $6 per ton. Though this 

 is more than it would cost to supply 

 the coal, considerable allowance can 

 be made for the saving in firing, remov- 

 ing ashes, etc.

A SMALL CARNATION HOUSE. 



I have just completed a small green- 

 house and want some advice about the 

 piping and lieating of it. I intended 

 to use it for vegetables, but have de- 

 cided now to bench it for carnations 

 and other flowers and add a lettuce 

 liouse later. The house is 21x31, of 

 Moninger semi-iron construction, and 

 runs north and soutli, with the boiler 

 room at the nortli end. There is top 

 and side ventilation on the east side. 

 The liouso stands on a concrete founda- 

 tion and is twelve feet high to the 

 ridge and six feet to the eaves, with 

 five feet of glass in the west wall. My 

 plan was to use 2-inch pipe throughout, 

 installing two 2-inch overhead flows 

 and ten 2-ineh returns. 



K. G.— Kan. 



For a carnation house 21x31, with a 

 ventilator in the east wall and five feet 

 of glass in the west wall, and having 

 1,250 to 1,400 square feet of glass, we 

 would recommend between 300 and 350 

 square feet of radiation, depending 

 ui)on the ox])osure and the actual 

 amount of glass.

Kroesdieli Water Tube Steam Boiler 



Wouldn't you be surprised if some morning you picked up your 

 florists' trade paper, and while turning the front cover, you see a 

 double page advertisement announcing that Kroeschell Bros. Co. will from 

 this moment on build and erect greenhouses— big 30-60-80 footers in width, 

 even twice as long and again as wide as any of the greenhouse companies, 

 who have specialized in this class of work for more than a decade? 



Wouldn't you wonder and wonder if we claimed that our green- 

 houses were built stronger and better, because of some fandangled 

 feature of coDstruction, whereby we made an old-time, obsolete type of 

 house just a little different in order to be different for sake of a talking 

 point? WELL, YOU NEED NOT WORRY, we are not going to do any- 

 thing of the kind. 



Our business (established 1879) is to build boilers of all types, 

 from the smallest house heater to the largest 600 H. P. Water 

 Tube Steam Boilers. We do not claim that we are wizards at designing 

 freak boilers. Our practical experience— engineering knowledge and reputa- 

 tion would not permit this. 



For thirty-eight years, we have confined our entire efforts to the 



designing and construction of high grade boilers, and during this 

 time have served the florist trade of this country and foreign countries to 

 the full satisfaction of every one of our customers. 



The famous Kroeschell Greenhouse Boiler has made a wonderful 



record for greenhouse heating, because of its practicability — 

 high efiiciency and unequaled fuel economy. 



Men who know boilers ^authorities on boiler construction — 



admit that our Hot Water Boiler and the Kroeschell Water Tube 

 Steam Boiler are positively the best hot water and steam units ever 

 designed for greenhouse heating. 



The high efficiency of the Kroeschell is due to its immense direct 



self-cleaning heating surface (a very small proportion of flue sur- 

 face is used)— the thin vertical waterways — the large combustion space — 

 long fire travel (longer than any other boiler)— its perfection of construc- 

 tion—honest and "true blue" rating. 



These qualities combined with the workmanship and material 

 are an inspiration to every boiler maker — it sets the standard 

 for all other boilers. 



As stated before, do not worry about our going into the green- 

 house building business — we will continue as boiler makers, to 

 build only the highest grade of boilers. We will strive to make them 

 better all the time.
