Greenhouse Heating. 



A MICHIGAN ADDITION. 



I wish to build an addition, 22 z 65 

 feet. The side walls will consist of 

 thirty inches of concrete and forty- 

 eight inches of glass. The height to 

 the ridge will be about twelve feet. 

 The house will be slightly protected. 

 I wish to maintain a temperature of 60 

 degrees in zero weather. How many 

 2-inch pipes will be necessary to heat 

 this house with hot water f What size 

 and number of flow pipes will be neces- 

 sary? Will a fire-box boiler, seven 

 and one-half feet long and twenty-eight 

 inches in diameter, set one foot lower 

 than the lowest pipe, heat this house 

 and another, 12 x 50 feet, without 

 crowding it? E. F. C. 



To heat a house such as described 

 to a temperature of 60 degrees in zero 

 weather will require three 2V^-inch 

 flow pipes and fifteen 1%-inch returns. 

 Two of the flows can be on the side 

 walls and the other under the ridge. 

 To get the best circulation, run the 

 flow pipes at a slight fall to the farther 

 end of the house and there connect 

 with the returns, which can be arranged 

 in three or more coils. To readily heat 

 the two houses, the boiler shoiild have 

 about five feet of grate surface. 



OBEENHOUSES AND BESIDENCE. 



Please give me information as to the 

 piping of my houses and the size of 

 boiler that I shall need. I wish to 

 use a sectional boiler, so that I can 

 add to it when necessary. 



I have four houses, each fifty feet 

 long. House No. 1 is ten feet wide. 

 The south wall is four feet high, double 

 sheeted and weather boarded. The 

 north wall is five feet high, double 

 sheeted and protected by other houses. 

 The height to the ridge is eight feet 

 and the roof is one-third span. I 

 want this house heated to 60 degrees. 

 House No. 2, north of No. 1, is four- 

 teen feet wide, with side walls five 

 and five and one-half feet high, double 

 sheeted and protected by other houses. 

 It has an even-span roof and is ten 

 feet high to the ridge. It must have a 

 temperature of 60 degrees. House No. 

 3 is twenty feet wide, with S^^-foot 

 and 6-foot double sheeted walls. Its 

 height to the ridge is eleven feet. I 

 want this house heated to 55 degrees. 

 No. 4 is a propagating house, six feet 

 wide; it is a lean-to, built against the 

 north side of house No. 3. The north 

 wall is four feet high and double sheet- 

 ed; it is entirely unprotected. All 

 the houses have glass in the ends, down 

 to four feet from the ground. There 

 are doors in each end of all the houses. 



All the houses run east and west 

 and the boiler pit is at the southeast 

 comer of house No. 1. I wish to run an 

 underground pipe to my residence, 

 which is only twenty feet from the 

 boiler, and heat a long hall in the

are all satisfied with the results it has fiven. nnd many 

 duplicate orders is the proof. ThlB Valve will main- 

 tain a steady pressure on ttie low side, no matter 

 how the initial pressure fluctuates. By carrying 40 or 50 

 pounds pressure on the boiler and setting the valve to 

 carry 6 or 10 pounds on the line, you always have a 

 reserve to fall back on in case of a sudden drop in tt^m- 

 perature. Our new catalosrue is ]ust out and if 

 you contemplate mailing any cuanges you had better 

 get one — it is yours for the asking.
