but to heat the two houses and 1,000 

 square feet of hotbed sashes it should 

 have a rating of 2,400 square feet of 

 radiating surface. 



In piping the houses, run one flow 

 pipe on each wall and the other two 

 feet under the ridge, and at tho south 

 end of the houses connect with the 

 o.oils underneath, of which there should 

 be three, with four pipes in each, in 

 the rose house, and three in the carna- 

 tion house. 



INSTALLED BY LOCAL PLUMBER. 



We had a heating plant put in our 

 greenhouses here for hot water and it 

 was put in for a pressure system, with 

 a safety valve which has thirty pounds 

 set on it, with a large iron ball put 

 on the expansion tank. At the first 

 test the plumber burst out the back 

 section of the boiler. We got a new 

 section and the nipple on the bottom 

 part of it did not fit tightly. The 

 plumber used a block and pounded it 

 with a sledge, and used a wooden log 

 and rammed it together. After that 

 we found a crack on the inside of the 

 new section, where the plumber rammed 

 it. The section is cast-iron; will that 

 stand pounding? 



The highest point of the expansion 

 tank is twenty-five feet above the 

 boiler and one of the greenhouses goes 

 uphill. Will the boiler send water up 

 through six IJ^-i^ch pipes, put to- 

 gether with manifolds and fed by 1%- 

 inch pipe, with a li4-inch return? Will 

 the boiler send water up like that and 

 discharge the expanding water with 

 twenty or thirty pounds of weight on 

 top of the expansion tank and with' no 

 opening on the system? Will it raise 

 that safety valve? Is it right to place 

 the feed pipe for hot water at the bot- 

 tom of the radiator, and the return also 

 at the bottom? All the pipes are run 

 uphill to the end of the greenhouse and 

 then return. Can we get circulation 

 to the end of the greenhouse fast 

 enough? H. & P. 



Whether a cast-iron boiler will stand 

 a pressure of forty or fifty pounds to 

 the square inch will depend entirely on 

 the size and construction of the sec- 

 tions. Ordinarily it would be too much 

 for very large or thin sections. Of 

 course, cast-iron will not stand much 

 hammering and it is probable that the 

 section referred to was cracked in that 

 way, rather than by the high pressure 

 carried. 



It is a mistake to try to carry water 

 for a 250-foot coil with a 1^-inch 

 return, even though it is under pres- 

 sure. In a system such as is described, 

 it makes little difference whether the 



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 Standaitl" 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.
