Greenhouse Heating. 



SuBSCRiBEES are invited to write the 

 Editor of this Department with regard 

 to any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Eeview to make a choice of 

 apparatus for you. The greenhouse 

 heating equipment advertised in this 

 paper is, we believe, the best for the 

 trade to buy, and each article the best 

 in the special field of its adaptation. 



CAPACITY OF BOIIJU&. 



When asking for information in a 

 former letter to you, I said my boiler 

 was 3x14 feet. I should have said 

 4x14 feet. Would such a boiler heat 

 an additional twenty-five feet of my 

 carnation house, making the house 22x 

 115 instead of 22x90? E. W. O. 



The number and size of the tubes in 

 the boiler are not stated, but it will 

 be underrated if its capacity is esti- 

 mated at the rate of one horse-power 

 for each tube, provided the tubes are 

 3-inch, and proportionately for larger 

 or smaller tubes, and at a iow estimate 

 each horse-power will furnish heat far 

 300 square feet of glass in small houses 

 and twice that amount in large ones. 

 From this it is evident that the 

 boiler would heat several houses of the 

 size described. 



TWO WYOMING HOUSES. 



I have a lettuce house 20x115, three- 

 quarter-span, with the long sashbars on 

 the south side. The house is nine feet 

 high to the ridge, eight feet high at the 

 back and four and one-half feet high 

 at the south side. There is glass in 

 the ends, but none in the sides. There 

 are two 8-foot beds against thft walla. 

 I am now using coils for heating, but 

 they are not satisfactory. In repiping 

 the house I wish to use the pipes I 

 have, which include two runs of 2%- 

 inch and eight runs of 2-inch pipes. 



I am also building another house, east 

 of and in line with my lettuce house. 

 The new house is 22x90, fourteen and 

 one-half feet high to the ridge, five feet 

 high at the low side and eight feet 

 high at the back. The sashbars on the 

 south side are eighteen feet long; on 

 the north side, nine feet long. There 

 is glass in the ends and twenty-eight 

 inches of glass in the south wall. In 

 this house there is a 3-foot bench at 

 each side, with two 5-foot benches be- 

 tween. These benches are all raised. 



The outside temperature dropped to 

 28 degrees below zero here one night 

 this winter. My houses have some 

 natural protection, being located on a 

 south hillside. The boiler will be two 

 feet below the level of the ground and 

 will be placed between the two houses, 

 which are twenty-two feet apart. It 

 is a return tubular boiler, 3x14 feet, 

 and contains thirty-two 3-inch flues. 

 The fire-box is four feet by four feet 

 two inches. There are two openings at 

 the top of the boiler, one of them 5-inch, 

 the other 2J^-inch. The return opening 

 is 3-inch. We do not have city water 

 pressure. 



Please tell me how to use headers. 

 Should I butt the glass in my new 

 house? Should I run the main flow 

 directly up from the boiler and into the 

 houses, or could I run the flow under- 

 ground until it is inside the hbuses and

 the 3-inch return opening in the boiler 

 be large enough? Will the connecting 

 of the two houses to one return retard 

 the water from one or the other on its 

 way to the boiler? Would my boiler 

 heat any more glass than that in the
