The Rorists^ Review 



OCTOBEB 25, 1917. 



Provided the flows run downhill, as 

 ■we infer to be the case, with the 

 changes suggested there should be no 

 difficulty in obtaining the desired tem- 

 perature. However, unless the returns 

 are well above the boiler or the system 

 is run under pressure, we would prefer 

 to use eight l^/^-inch return pipes rather 

 than ten 1^/4 -inch. 



USE A HOT WATEE SYSTEM. 



I expect to build two greenhouses, 

 each 12x50. There will be one foot of 

 glass in the side walls of one of the 

 houses; the other house will have glass 

 only in the roof. What will be the best 

 way to heat the houses? The coldest 

 weather we have here is about 16 de- 

 grees below zero. The house with glass 

 in the walls will have raised benches 

 and will be used for genpral purposes. 

 The other house will have solid beds. 

 What will be the best size of pipe to 

 use and what will be the best way to 

 arrange it? Will an upright boiler of 

 ten horsepower be suitable for the 

 houses? Will it be better to install a 

 hot water or steam system? 



T. L.— Utah. 



For houses of the size mentioned, it 

 will be advisable to install a hot water 

 plant. An upright boiler can be used, 

 provided it can be so located that the 

 top of the boiler will be lower than the 

 returns. However, a boiler rated for 

 750 to 800 square feet would suffice. 



To maintain a temperature of 60 de- 

 grees in the house containing solid beds, 

 we would run a 2-inch flow pipe upon 

 each plate, giving a fall of one inch in 

 fifteen feet, and connect each flow at 

 the farther end of the house with three 

 2-inch or four li^-inch return pipes. 

 Each c_oil should then be connected with 

 the boiler by a 2-inch return main. 



For the house with raised benches, 

 which has one foot of glass in each side 

 wall, we would use one 2%-inch flow 

 pipe, carrying it a foot or so below the 

 ridge, and connect with eight 2-ineh re- 

 turns, located under the benches.

The Maxket. 



Despite scarcities in a number of 

 items, conditions last week showed a 

 marked improvement. Eoses are of poor 

 quality, and carnations are not to be 

 had. Mums are arriving, liowever, and 

 the quality is good. Business last week 

 was an improvement over that of the 

 previous week. Funeral work was plen- 

 tiful. ^ 



Bulbs at last have come and the deal- 

 ers handling them have been exceed- 

 ingly busy. 



Various Notes.
