WHAT THE USERS SAY 



Test at 8<-' below zero— No. 8 Kroeschell Boiler carries 80,500 



square feet glass. 



Our heating systom works t« perfection. To our surprise the new No. 8 Kroeschell 

 Boiler mastured the whole plant, consisting of 5 houses. 20x150. We only deemed it neces- 

 sary to start our second boiler when the temperature went down to 8" below zero. 



We hail expected to use both boilers in cold weather, but the one boiler did such 

 excellent work that we did not run the two boileri until the very cold weather set in. It 

 was a very easy matter to keop the temperature up in the very coldest weather and 

 stormiest nights. The 5 houses have 20,500 square feet of glass; the No. 8 boiler is rated at 

 16,500 square feet of glass.

WATER DOES NOT BOIL. 



I have a house 16x30 feet, four feet 

 to the plates and nine feet to the ridge, 

 with eighteen inches of glass in the 

 sides. I am heating it with a hot-water 

 tank heater. I have three 2-inch flows, 

 running overhead to the farther end of 

 the house. There they drop into mani- 

 fold and each flow returns through six 

 114-inch pipes under each of the three 

 benches. I have a generator. 



I can hardly get the returns hot 

 enough to burn the bare hand near the 

 boiler. The water never boils; in fact, 

 I cannot make it boil. I have no great 

 trouble in keeping the house warm, but 

 can get no bottom heat. Have I too 

 many pipes and too much water for 

 the boiler? If so, how should I change 

 it? The house is air-tight. I am lo- 

 cated in central Indiana. E. F. 



From the data given, it would seem 

 that the heater is too small to bring 

 the water to the boiling point, but, as 

 there is nothing which indicates the 

 size of the heater, this can not be 

 definitely stated. If this is the case 

 the generator will not be of any assist- 

 ance in heating the house, as it is only 

 eflfective when the boiler is large 

 enough to raise the temperature of the 

 water above 212 degrees. 



If the present system is not sufficient 

 to maintain the desired temperature, 

 the size of the boiler should be in- 

 creased, as, provided the circulation is 

 good and the water in the heater does 

 not boil, there is no other change that 

 would do any good. However, it should 

 be stated that the house contains 

 twenty-five per cent more radiating 

 surface than should be required to 

 maintain a temperature of 60 degrees, 

 with an open tank. With a closed sys- 

 tem and with a heater of ample size, it 

 should be possible to take out one-half 

 of the pipe in the coils, but, if the 

 circulation is good, anything of the 

 kind would only tend to increase the 

 fuel consumption without affording 

 more heat, unless the size of the boiler 

 is increased. 



The statement is made that no bot- 

 tom heat can be secured. Of course 

 the amount of heat given off by the 

 pipes would be materially increased if 

 the water could be carried at 200 de- 

 grees or more, but if to obtain this the 

 number of the pipes has to be lessened, 

 nothing would be gained. At best there 

 is little bottom heat unless the sides of 

 the benches are at least partly enclosed, 

 so as to confine the heat. If it is 

 merely desired to get more bottom heat, 

 this might have the desired effect.
