INSUFFIQENT RADIATION. 



I have two parallel greenhouses, heated 

 with hot water. They have 4-foot walls 

 and measure ten feet to the ridge. They 

 are double boarded with matched lumber, 

 with two thicknesses of tar paper be- 

 tween. In House No. 1, which is 16x60 

 feet, the main leaves the boiler in a 

 3% -inch pipe and then divides into two 

 2% -inch flows, each of which feeds five 

 2-inch return pipes. House No. 2 is 

 16x53 feet, with an ell 15x30 at the far 

 end. In this house the 3^ -inch main, 

 after leaving the boiler, is divided into 

 two 3-inch flow pipes, each feeding five 

 2-inch returns. All pipes have an up and 

 down grade of one inch to ten feet, and 

 have a direct drop of twenty inches 

 where they enter the boiler. All flows 

 are overhead. I have in use a No. 624 

 Burnham hot-water boiler, with six sec- 

 tions and a grate surface 24x30 ' inches. 

 I burn soft coal. House No. 2 has glass 

 in the gables. I wish to maintain a tem- 

 perature of 55 to 60 degrees. Is the 

 boiler large enough to do this without 

 forcing it? 



The dimensions as you have recorded 

 them are not sufiicient to enable me to 

 give an accurate estimate of your plant. 

 It is evident, however, that the piping 

 is insufficient to maintain even a tem- 

 perature of 60 degrees. The radiation 

 should be 1,000 square feet for a tem- 

 perature of 60 degrees, and it is evident 

 that there is less than 900 square feet 

 of radiation in the houses. If your boiler 

 has a rated capacity of 1,500 square feet 

 it is large enough to handle the plant 

 without forcing. L. C. C. 



WRONG INSTALLATION. 



I have an east and west greenhouse, 

 14x40 feet, heated by a Wilks hot water 

 heater. There are three benches, with 

 three l^^-inch flow pipes under each side 

 bench and four under the middle bench. 

 There is one 1^-inch return pipe under 

 each bench. The boiler is about two 

 feet lower than the pipes, which grad- 

 ually rise about fifteen inches. The ex- 

 pansion tank is at the highest point. 

 This arrangement did not prove entirely 

 satisfactory. It was hard work to keep 

 the heat up on extremely cold or windy 

 days. "What change would you suggest, 

 using the l^^-inch pipe? I am planning 

 to build a 10-foot lean-to and wish to 

 use 4-inch pipe. How should it be ar- 

 ranged? E. W. G. 



If I read the description of your heat- 

 ing plant correctly, it is little wonder 

 you have difficulty in maintaining heat 

 in the house. It is installed wrong end 

 to ; that is, you have too many flow pipes 

 and too few and too small returns. If 

 you will rearrange the heating plant by 

 carrying one 2-inch pipe from the boiler 

 under the ridge to the far end of the 

 house, there divide it to supply three 

 coils of 1%-inch pipe of four pipes each 

 under each of the three benches, ana 

 then reunite these near the boiler into a 

 common 2-inch return, you will have the 

 plant right end to and sufficient for a 

 temperature of 60 degrees. Connect the 

 expansion tank by a %-inch pipe to the 

 main return within a foot of the boiler 

 and carry it six to ten feet above the

PIPING FOR CARNATIONS. 



I have a greenhouse 30x44 feet, ten 

 feet to the ridge, with 5-foot walls of 

 double, ship-lap siding; no glafis in sides. 

 I have one 2-inch flow pipe and ten 1- 

 inch returns to the furnace, with seven- 

 ty feet of coil in the furnace to heat the 

 water, and a 10-inch flue direct from 

 the furnace to the far end of the house 

 and out. Now, I would like to take out 

 the flue. How much more 1-inch pipe 

 will I need to heat the building for 

 carnations, geraniums, etc., and how 

 many flows of 2-inch pipe will I need? 

 I have heated the building for ten years 

 with the flue and ten 1-inch pipes, but 

 I want to grow carnations on a bench 

 over the flue and that would make the
