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 help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



NEED HEAT ECONOMY. 



To Cut Coal Costs. 



Whether high-pressure steam, low- 

 pressure steam, vacuum, hot water, 

 gravity or forced circulation — no matter 

 what system is used — the heating me- 

 dium has a definite cost value and con- 

 sequently the question of heating your 

 greenhouses is one of the most important 

 factors in the greenhouse business. 



In the days gone by, many florists 

 were more or less indifferent about the 

 heat losses and boiler losses, but with 

 the increased cost of fuel, it becomes 

 a matter of the greatest importance, and 

 I shall endeavor to point out, briefly, 

 some of the commonplace conditions re- 

 sulting in fuel waste. 



Many have learned by experience that 

 any kind of boiler or trust-to-luck pip- 

 ing system will not make a practical 

 greenhouse heating system and conse- 

 quently there is a growing and active 

 desire among florists to adopt modern 

 equipment and methods. This is a pro- 

 gressive habit, commendable, business- 

 like and profitable, and it pays. 



Eliminate Leakage. 



Air leakage in boiler settings need no 

 longer be tolerated, because the heat 

 losses so incurred may be entirely elim- 

 inated by applying any of the numer- 

 ous compounded cements made for this 

 purpose. Make the boiler walls air-tight 

 and insulate exposed surfaces of your 

 boiler. 



Proper furnace design and accurate 

 boiler setting dimensions are vitally im- 

 portant, and it is a mistake to consider 

 Ihe masonry work of any boiler simply 

 as a matter of so many bricks and some 

 mortar. We find it pays to engage an 

 experienced boiler masonry contractor 

 for this class of work, and many of the 

 florists for whom we have supplied large 

 high-pressure steam units will verify 

 this statement. 



Should Bemove Soot. 



Soot-covered heating surfaces should 

 not be tolerated. When you stop to 

 think that one-sixty-fourth of an inch 

 of soot has the same heat resistance as 

 five-sixty-fourths of an inch of asbestos, 

 it is needless to say that soot should 

 1)0 removed at frequent intervals. 



For hot water and low-pressure heat- 

 ing boilers hand-cleaning must be ad- 

 hered to, and for it we recommend the 

 single blade adjustable type cleaner. 

 Make it a rule that the tubes be cleaned 

 down to the surface of the metal every 

 time. High-pressure steam units should

TO THE MAN WHO NEEDS A BOILER 



"The customer's interest first"— is the basis of the KROESCHELL standard. This 

 principle makes the KROESCHELL Poller the most liberal of all in the Oreen- 

 house Boiler buaineas. The great variety of boilers that we make places us in a 

 commanding position. It is the KROESCHELL principle to supply only the type 

 of boiler best suited for the conditions. For this reason we always furnish the 

 most efiScient boiler unit in every case.

The KROESCHELL has proven its worth in many of the large establishments in 

 this country. It has frequently been selected by the most careful buyers in 

 competition with all other types of boilers. Its eflSeiency and capacity are com- 

 pletely beyond any other boiler. 



KROESCHELL BOILERS have no bulky, soot accumu- 

 lating surfaces— you avoid the disagreeable work and 

 trouble indispensable to cleaning boilers with compli- 

 cated and tortuous back and forth passages. 



The superiority of our boilers has resulted in the removal and abolishment of 

 hundredsof cast iron sectional boilers— in every instance KROESCHELL BOILERS 

 give more heat with the same piping with less fuel.
