NECESSARY BOILER CAPAQTY. 



Please give me information as to the 

 size of boiler required to heat the fol- 

 lowing greenhouses, in the climate of 

 southern Ontario: One house 21x100, 

 one house 18x100, and one house 20x60. 

 The houses measure six feet to the plate 

 and twelve feet six inches to the ridge. 



Our present boiler is thirty-six inches 

 by nine feet eight inches and contains 

 thirty-four 3-inch tubes. It did the work 

 for the two 100-foot houses. We have 

 added the 60-foot house and would like 

 your opinion. The 60-foot house will be 

 used for cucumbers and will require a 

 temperature of 65 degrees. If the pres- 

 ent boiler is not large enough, how large 

 a boiler would you advise putting in! 

 Kindly state the size of grate surface re- 

 quired in either case, for steam heat. 



H. E. B. 



Your present boiler should, when 

 working under full capacity with water 

 at 180 degrees, heat all three of the 

 houses to 70 degrees during zero weather. 

 If the 100-foot houses are safe at 60 

 degrees, as the cucumber house will be, 

 the boirer should have capacity enough, 

 but there is no factor of safety allowed. 

 Everyti^ng is figured at full capacity. 

 In adding to the plant, the future glass 

 area will in large measure determine the 

 plans for increased boiler capacity.

DEPENDS ON THfe PIPES. 



I shall appreciate a little information 

 through your valuable paper, about my 

 heating plant. I have a large, nine-sec- 

 tion Ideal steam boiler which I have 

 been using two seasons to good advan- 

 tage with hot water, as I cannot stand 

 the pressure of staying up nights, firing 

 up, and as yet cannot aflford a fireman. 

 I have one house 40x60 feet, one 16x40 

 feet, one 10x45 feet, and I want to 

 change from hot water to steam, using 

 natural gas for fuel. I do not want to 

 disturb my heating pipes. Can I use the 

 same system! I have been told here in 

 Pittsburg, if water works, so will steam. 

 Any information you can give, as to 

 what I must do in making the change, 

 will be fully appreciated. G. J. L. 



It is impossible to answer your ques- 

 tion in a satisfactory way because you 

 fail to state the size of the pipes you are 

 at present using in your greenhouses. If 

 the houses are piped for hot water, and 

 you have suflBcicnt radiation to hold the 

 temperature desired during cold weather, 

 the chances are that you have too many

Gentlemen:— You can atroD^ly and untaeaitatlDrly recommend the 

 "Eclipse" piston type reductnr valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as s<>nBitlve as a watch. We will be in Chicago soon to take up 

 the vacuum system with you. Vours truly,

pipes for steam, and probably also too 

 large ones. If the houses work well on a 

 hot water basis with coal, they will work 

 as well or better with gas. If you lack 

 radiation during cold spells the chances 

 are that you can best run on hot water 

 during mild weather and convert to steam 

 for cold spells, thus increasing the capac- 

 ity of your plant without materially mod- 

 ifying it. If you hav6 cast-iron pipes, 

 however, the steam plant is out of the 

 question. L. C. C. 



PIPING A LEAN-TO. 



How would you pipe a lean-to house,

 we have them on handf Our heating

I would not sidvise any one to attempt 

 to heat a 100-foot house with 1-inch pipe 

 using hot water; 2-inch is about right,
