Greenhouse Heating. 



LEAKY UNDEEGEOUND EETUEN. 



We have a range of six greenhouses, 

 with the boilers at one corner of the 

 range. Our present steam heating sys- 

 tem has been in use for fifteen years. 

 The main return pipe runs crosswise 

 of the six houses and is laid under 

 the surface of the ground, in sewer 

 tile. The farther end of the return 

 pipe is below the water level in the 

 boiler and about two feet below the 

 ground; it runs on a gradual slant to 

 the bottom of the boiler. This pipe 

 is wearing out and is leaking, but we 

 do not know where the leaks are. As 

 we do not wish to tear up the whole 

 return to find the leaks, would it be 

 just as well to place a new return pipe 

 above ground, on the floor level of the 

 greenhouses? The ground has a drop 

 of about eighteen inches in 100 feet 

 toward the boiler. At the boiler house 

 the return would drop to the floor un- 

 der the boiler and then rise into the 

 boiler, in the form of a U. C. B. 



If the plan for replacing the return 

 is correctly understood, the new re- 

 turn pipe would run across the ends 

 of the houses just below the level of 

 the coils, and two to three feet above 

 the level of the water in the boiler, 

 while as now arranged it is slightly 

 below the water level. There is no rea- 

 son whatever why the proposed change 

 would interfere with the return of 

 the water to the boiler. On the con- 

 trary, it should be found helpful, as 

 there will be no backing up of the 

 water in the returns. The return can 

 be dropped to the floor of the boiler 

 room and enter the boiler from below, 

 as proposed. 



AN ADDITION FOE EOSES. 



We have two even-span houses, 18 x 

 75 feet, connected, with a shed along 

 the west end their entire width. Each 

 house has two 2 1/2 -inch flows, feeding 

 nine 2-incli returns. The boiler is 

 tapped for two 3-inch flows and two 

 3-inch returns. We propose to add one 

 house for roses, south of the other 

 houses, and wish to maintain a tempera- 

 ture of 60 degrees in this Ohio climate. 

 How would you make connection at 

 the boiler to feed the houses properly? 

 We thought of running both flows to a 

 header and then connecting the three 

 3-inch flows to this, one supplying each 

 house. Will one 3-inch return take 

 care of the two south houses! How 

 would you pipe the new house, and also 

 a 10-foot section at the west end, to be 

 used as an entrance or temporary plant 

 room, where retailing will be done? 



We want this new part to be heated 

 in good shape, as the system works 

 finely in the two present houses and we 

 do not want to take any chances next 

 winter, when the house is full of roses. 

 We should rather have a little more 

 piping than is absolutely necessary.

WHAT THE USERS SAY 



Better than All Others 



I have fired boilers for the last forty years. Th* Kroaschall Is th« best I hav* avar 



usad. I have two (»gt iron boilers, also a locomotive boiler coupled with yours, but did not 

 need to use the cast iron boilers this winter. Your No. 7 boiler is ratad at 18,000 sq. ft. ef 

 Klaaa and carrias 2S,000 aq. ft. of glass until the outside temperature goes down to lO'' of 

 frost. We have no trouble to keep temperatures in our houses with easy tiring since we in- 

 stalled your boiler. From the boiler to the farthest end of our violet houses and return is 800 

 feet, and circulates very quiclcly. The 8altfoki> Flower Shop.

More Heating Surface

and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



^'Superior Standard" Greenhouse Boflers 



find them perfectly satisfactory. We frequently receive re-orders 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
