BOILER FLUES 



#1 



SELECTED 



We make a specialty of handling carefully selected Boiler Flues, 4-inch 

 diameter and other sizes for greenhouse piping, Gutter Posts, etc. Also 

 we make a specialty of flues for retubing boilers. All flues are thor- 

 oughly cleaned and trimmed, ready for use. General sales agents for 

 Stuttle's Patent Clamp for joining flues— no packing, no leaks. 

 New Standard Pipe and all kinds of Greenhouse Fittings. Right prices 

 and prompt shipment.

to raise the temperature of the water in 

 the flow pipe, thus lessening its weight. 



It makes no difference where the ex- 

 pansion tank is connected, except that 

 if attached at the highest point it will 

 do away with the necessity for air 

 valves. The expansion tank should be 

 large enough to supply the water likely 

 to evaporate from the system, as well as 

 for the expansion of the water. The 

 latter is usually alJout two and one-half 

 per cent in an open system, and from 

 three and one-half to four per cent in 

 one that is closed. In a general way it 

 will answer to use a tank with a capac- 

 ity of one gallon for each 100 square 

 feet of radiating surface, plus five gal- 

 lons for an open tank system, and fifty 

 per cent more than this when the sys- 

 tem is closed. 



The smaller greenhouse boilers are de- 

 signed for use with hard coal and they 

 are rated accordingly. For use with 

 soft coal the grate surface of such boil- 

 ers should be increased twenty-five per 

 cent and they should be so arranged 

 that they can be readily cleaned. 



Unless the boiler is several feet below 

 the level of the returns, it Js not ad- 

 visable to use pipe as small as 1 14 -inch 

 for runs of more than fifty feet, owing 

 to the increased amount of friction in 

 small pipes, except in connection with 

 a closed system. 



STEAM OB HOT WATER? 



Will you please tell me the number 

 and size of pipes, with the best ar- 

 rangement of them, for a house 28x120, 

 with roof bars sixteen feet long? There 

 are sixty-four inches of glass in the 

 walls and one end is glass. I want a 

 temperature of 60 degrees when the out- 

 side temperature is 10 degrees below 

 zero. What size of boiler would be re- 

 quired for three such houses and which 

 would be the more economical, hot 

 water or steam? In piping for hot 

 water, which way should the feeds 

 slope, up or down, toward the far end 

 of the house? There are no benches in 

 the house, but there are two rows of 

 purlin posts. My location is southwest- 

 ern Ontario. R. H. E. 



Hot water would be preferable for 

 one house, but there would be little 

 choice between steam and hot water if 

 three houses are to be heated. Steam 

 will be considerably less expensive to 

 install, but the cost for fuel will be 

 slightly greater and it will be more 

 trouble to keep up the fire at night. 

 The boiler for the three houses should 

 be of at least thirty horse-power, with a 



Some Summer Time Things 

 It's Time to Do 



wow THAT you (rrowers ate Retting your business methods down to a point where 

 ^^ you closely cut the corners on all unnecessary expense, you are appreciating the 

 saving there is In early overhauling your entire heating plant. 



This waiting until you want heat before doing anything doesn't agree with tlie 

 careful way you do other things. 



Some Inconveniences— like painting— can't be helped. But this getting your 

 heating In 8bap« can be. 



If your boiler needs new grates- get them now and put them in. 



If some of your pipe hooks have slipped and aSectod the circulation — give them 

 attention now. 



If the circulation In your pipes .was sluggish last 8<>a8on, send for one of car 

 expert heating men to go carefully over it and ferret out the trouble. 



If you need a new boiler, don't wait until Jack Frost forcibly calls your attention 

 to the necessity. Order it now and make sure of its early delivery and ample time 

 for its erection and connecting up. 



Very seldom you are able to accomplish things sooner than you expected. The 

 safe way is to allow more lime than you think you need. 



The fact that we have bj'cn healing greenhouses for going on 64 years, is pretty 

 strong evidence of our ability to heat them the economical way ihey should be heated. 



We shall be looking to hear from yon.
