twenty feet or a little more. To heat 

 such a house to 55 de^ees under the 

 severe conditions mentioned, I should 

 use seven 2-inch flow pipes and fourteen 

 2-inch returns. It would be far better 

 to put in five 2^-inch flows and fifteen 

 2-ineh returns. Bun one flow on each 

 plate, another two feet below the ridge 

 and distribute the others as well as pos- 

 sible. 



While a coil boiler may be constructed 

 in the manner described, I should pre- 

 fer to use a regular boiler rated for 

 about 2,000 square feet of radiation. 

 A coil boiler to heat the house should 

 contain about 100 square feet of fire 

 surface, which would require about 

 twenty-five flues of 2-inch pipe six feet 

 long and six square feet of grate. The 

 cost would be about one-half that of a 

 regular boiler. 



PIPING IS UNSATISFACTORY. 



I should like to ask you a question or 

 two about the heating of my two green- 

 houses, which are located, as you see, in 

 the southern part of New Brunswick, 

 Canada. My heating system did not 

 work well last winter and I want to see 

 whether I can improve the piping in 

 some way. The houses are 52x300 and 

 twenty-two feet high to the ridge. The 

 side walls are eight feet high; the lower 

 half is stone and the upper half is 

 glass. I have two boilers, each 150 

 horse-power. How many 1%-inch pipes 

 will be needed to heat one of the houses 

 for roses f What is the best arrange- 

 ment of the piping? W. P. 



A simple way to heat the houses 

 would be to taie off five 2-inch flow 

 pipes, carrying one on each plate, an- 

 other ten feet below the ridge and the 

 others on the purlins; or, if there are 

 purlin posts, they may be on these, 

 eight or ten feet from the floor. Con-' 

 nect each of these flow pipes at the 

 farther end of the house with a coil of 

 1%-inch pipes, using six pipes in each 

 of the wall coils and three in each of 

 the others. 



The letter states that one of the 

 houses is to be used for roses, but it 

 does not indicate what temperature is 

 desired in the other house. In case 50 

 to 55 degrees will suffice, it will only be 

 necessary to use fifteen 1^-inch re- 

 turns, placing four on each wall and 

 two under the purlins, with three in the 

 middle coil. It would also be possible 

 to dispense with the overhead feed 

 pipes, putting in seven additional 1%- 

 inch pipes and distributing them among 

 the coils. The drip water can be re- 

 turned in a single 2-inch return or in a 

 1*4 -inch return from each coil.

Every Florist will be interested in the labor, fuel 

 and heat savins qualities of the Moreliead Sys- 

 tem. It returns the condensation to the buiier 

 at its initial heat. Thus the boilers are fed with 

 pore HOT water. Also you can keep your boilers 

 on the sround level and have perfect circula- 

 tion and drainace. It means all this and more to 

 install the "Morehead." Write for the reason why.
