Greenhouse Heating. 



A SMALI. OHIO HOUSE. 



1 am building a small greenhouse, 

 22x60 feet, four and one-half feet to the 

 eaves and eleven feet to the ridge. It 

 runs east and west. The north wall, ten 

 feet of the west end and five feet of the 

 east end will be built of 8-inch tile 

 blocks, laid in cement; the south wall and 

 the rest of the ends and gables will be 

 of ship-lap construction. I may, however, 

 use glass in the east end. We sometimes 

 have a few days of zero weather here. 

 The maximum temperature required will 

 probably be about 60 to 65 degrees. 

 Would a hot water boiler that is rated at 

 650 square feet of radiation be sufficient 

 to heat the house? What size and what 

 ttumber of flows arid returns should be 

 used and how should they be placed f 

 J. C. M. 



For a temperature of 65 degrees in 

 zero weather, a greenhouse 22x60 feet 

 will need about 540 square feet of radiat- 

 ing surface, so that there should be no 

 difficulty in heating it with a boiler hav- 

 ing a rating for 650 square feet. Two 

 2»4-inch flow pipes could be used, but it 

 Would be better to have three if heat is 

 needed under the middle benches, as is 

 usually advisable. With three flows use 

 twelve 2-inch returns, locating four on 

 each wall and four under the benches. 

 One flow could be upon each plate and 

 the other under the ridge.

OVEBHAULTNG THE SYSTEM. 



Having recently purchased a green- 

 house, I now find I must overhaul or 

 reinstall the heating plant. I have a 

 hot water system, but there are several 

 complete traps in the piping, so that 

 there are but three l^/^-ineh pipes that 

 could carry any water; the rest would 

 either be dead or extremely sluggish on 

 account of faulty piping. I understand 

 that last winter the plants as well as 

 the city water froze in the greenhouse. 

 We have an upright boiler of about five 

 horse-power, and 1%-inch pipes, both 

 flows and returns. The greenhouse is 

 2.'5x4Q. with 7-foot walls and stands 

 «a8t^md west. The south wall and 

 htfth «ads are about half boards and 

 half glass, while the north wall is all 

 boards. The winds come from the west, 

 as a rule, but sometimes there are cold 

 east winds. The boiler room is con- 

 nected at the northeast corner, between 

 the greenhouse and my dwelling;. There 

 ia one bench around the north side, east 

 end and south side; also two benches 

 running lengthwise, through the center, 

 and three aisles. 



I am thinking some of installing a

are all satisfied with the results it has viven. and many 

 duplicate orders is the proof. This Valye will main- 

 tain a steady pressure on tbe low side, no matter 

 how the initial pressure fluctuates. By carrying 40 or 60 

 pounds pressure on the boiler and setting the valve to 

 carry 5 or 10 pounds on the line, you always have a 

 reserve to fall back crii in ra.°e of a sudden drop in tem- 

 perature. Our new catalocue Is Just out and if
