Greenhouse Heating 



POINTS ON PIOKINa BOILERS. 



Tor Economical Operation. 



Every florist ia naturally vitally in- 

 terested in the economical operation of 

 his greenhouse. Among the many things 

 that engage his attention, the selection 

 of a suitable boiler is of paramount im- 

 portance. Unfortunately, in many 

 cases this question has not had the con- 

 sideration it should have had at the 

 proper time, and, as a result, the owner 

 is confronted by the tragic realization 

 that his boiler is not doing what he ex- 

 pected or what was claimed for it. 



Frequently purchasers are influenced 

 by the fact that a boiler is made in a 

 neighboring city and a saving in freight 

 and time of shipment can be effected by 

 buying locally. The purchaser will, no 

 doubt, realize, on further thought, that 

 this is one of the last things to be con- 

 sidered in selecting the boiler for the 



^'^BTcaTsr'of the fact that few florists 

 are engineers, I wish to suggest a few 

 points for your consideration regarding 

 boilers which I believe are important. 

 In the first place, it would be well to 

 give some thought to the manufacturer 

 and his organization. What service does 

 he give to customers and how far does 

 he go to back up his product? His 

 reputation is as important to you as 

 yours is to your bank. 



Difference in Ratings. 



Another important point to the flo- 

 rist is the question of the catalogue rat- 

 ing of the boiler. Let us take, for ex- 

 ample, two boilers of different makes, 

 each rated at 2,000 square feet. Upon 

 comparing the catalogues, we find that 

 one has a larger grate area than the 

 other and is, on the whole, of larger out- 

 aide dimensions. This brings us to the 

 matter of firing period, which may not 

 be mentioned in the catalogue, but 

 upon which the rating of the boilers is 

 based. It will, no doubt, be apparent 

 that if the two boilers mentioned above 

 are to produce the same amount of steam 

 or hot water per hour, the one with the 

 smaller grate area and generally smaller 

 size will have to be fired more often 

 than the larger one and will conse- 

 ([ueutlv burn more coal in doing the 

 same amount of work. Most low-pres- 

 sure boilers are claimed to be rated on 

 an 8-hour firing period; that is, atten- 

 tion once in eight hours, with about 

 twentv per cent reserve capacity for 

 kindling the next fuel charge. It is im- 

 portant, however, when comparing dif- 

 ferent manufacturers' boilers of the 

 same rating to ascertain that the ratings 

 of the boilers to be compared are based 

 on the same firing period, as this has 

 direct bearing on the fuel consumption. 



As you all know, a heating season is 

 composed of a large number of compara- 

 tively mild days and a relatively small 

 number of extremely cold days. Green- 

 house owners are compelled, however, 

 to design their heating plants of suf- 

 ficient size to maintain proper tempera- 

 tures under the most severe conditions, 

 and this means that for a considerable

TO THE MAN WHO NEEDS A BOILER 



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

 principle makes the KROESCHELL Policy the most liberal of all in the Green- 

 house Boiler business. 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 efficient 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 efficiency 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 

 hundreds of cast iron sectional boilers— in every instance KROESCHELL BOILERS 

 give more heat with the same piping with less fuel.
