Dear Sirs: I wish to write you a few lines concerninfr your No. 2 boiler which we received last 

 fall. Your boiler proved to be excellent in material and workmanship. It did the work very 

 nicely last winter with a small amount of coal. Others used up more than a carload while we 

 used only 15 tons all winter, inciuding what we used in the dwelling. Every one In our neiehbor- 

 hood has got a Kroeschell boiler. As soon as the other greenhouse men saw it they took a liking to 

 it and now they've all got one. We speak well of your boiler to all who see it. The Kroeschell is 

 our favorite if we ever get another. Yours Respectfully.

NOT CAST IRON-Has thin waterways. Heats quickly. It Is the most efUcient, 

 safest and most economical boiler built. Very powerful. 16 sizes, heating irom the 

 smallest greenhouse up to 50,000 square feet of glass to 60 degrees, at 15 degrees below 

 zero. Prices and catalogue on application.

DO NOT PAINT THE PIPES. 



We are thinking of painting the heat- 

 ing pipes in our new range with linseed 

 oil or lampblack, but we have been told 

 that it decreases their heating eflSciency. 

 Will you please advise us? J. F. C. 



. Do not paint your heating pipes. You 

 will regret it. The main flow through a 

 potting shed or under, the ridge, of a 

 house may be given a coat of asphaltum 

 varnish during the summer, but do not 

 paint the pipes under the benches or 

 along walls; rusty pipes are the best 

 radiators. L. C. C. 



, A WRONG USE OF THE TANK. 



I wish to know if my house will be 

 properly heated as I have it piped. It 

 is 20x36 and is located in eastern Massa- 

 chusetts. It has a 1%-inch feed pipe 

 from the boiler and three lines of 1^- 

 inch pipe on both sides and end. The 

 flow is direct from the boiler to the tank, 

 up in the gable. All three lines of 1^4 - 

 inch pipe are fed from the one 1%-inch 

 flow that leads from the boiler to the 

 tank, then down to the throe lines, around 

 to the boiler, and through one 1%-ineh 

 pipe into the- boiler. 



Now, this tank is c^st-iron, tight and 

 shaped like a watermelon, with a water 

 gauge on the we^ end and a regular boil- 

 er safety valve on the east end. I have a 

 Walker & Pratt boiler, with a 12-inch 

 grate and a fire-box twenty-four inches 

 deep. The question is, will this boiler 

 work all right with this piping? Every 

 particle of water goes through this tank. 

 The tank is half full, allowing for ex- 

 pansion. Would it be better to pipe 

 direct from the boiler to the three lines 

 of pipe, with a small pipe at the high- 

 est point into a tank, then from the 

 tank to the lowest return point? I can 

 heat the water in the tank so that it 

 will boil and blow off. W. D. B. 



What you wish to accomplish is, in 

 part at least, defeated by the plan used 



In a 



Position to Know 



Gentlemen: 



In 1896 I built my first greenhouse, and 

 every year have made some addition to the 

 business, until now we have over fifty 

 thousand feet of glass. 



Those who have built their business in 

 this way, from the cold frame up, usually are 

 best to judge the merits of a boiler. I can, 

 therefore, say the two Burnham boilers you 

 installed for us in 1904 have been most 

 satisfactory. We gladly recommend your 

 work. Yours very truly,

in piping. The aim should be to get 

 the water into the heating pipes as 

 quickly as possible after it leaves the 

 boiler. This is best done by carrying 

 the main flow pipes from the boiler di- 

 rectly into the radiating pipes. Usually 

 the hot water is carried from the boiler 

 in a single pipe to the far end of the 

 house and then distributed into the re- 

 quired number of pipes to heat the 

 house, the number varying according to 

 the size of the house, its exposure, the 

 climate in which it is located, and the 

 crops to be grown. Your house has just 



one-half the amount of pipe necessary to 

 maintain a temperature of 60 degrees in 

 your climate, in severe weather. Then, 

 too, with your present plan one side of 

 the house will receive much more heat 

 than the other, as all the hot pipes are 

 on one side and all the cool ones on the 

 other. 



The plan suggested, of carrying the 

 main flow from the boiler to the oppo- 

 site end of the house and there distrib- 

 uting to all the returns, which can then 

 be arranged parallel to one another, and 

 at the end nearest the boiler collecting
