The Flwists* Review

Where Tkerels Condeflsation 



— there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly—return the pure, hot condensation to your boiler without 

 pump or injector or make no charge for the trial. Obey that 

 impulse — write now.

thing larger than a 3-inch flow pipe, 

 and by placing thirteen 2-inch returns 

 upon the walls it will be an easy mat- 

 ter to maintain a temperature of 55 

 degrees in a greenhouse 27x62 feet. 



On several accounts it would be bet- 

 ter to use three 2%-inch flow pipes, of 

 which two could be on the plates or 

 under the purlins, and the other under 

 the ridge. In addition, eleven 2-inch 

 returns will be required. Three can be 

 located on each wall and five under the 

 benches. 



A 1-inch pipe leading from the high- 

 est part of the system to the expansion 

 tank will do away with the necessity 

 for using air valves. A 3-inch or 314- 

 inch main flow can be used to supply 

 the 2M»-inch flows and the eleven 2-inch 

 returns can be connected with the 

 heater by means of the two 2%-inch 

 main returns. 



NOT AN ECONOMICAL PI.AN. 



I am enclosing a sketch of a house 

 which I have leased for the winter, 

 and which I wish to plant with general 

 bedding stockt The house contains 

 only about half as much piping, in pro- 

 portion to the amount of space, as my 

 own houses contain, but it can not be 

 denied that the owner has been suc- 

 cessful in growing lettuce there for 

 two winters, though the outside tem- 

 perature in this part of Pennsylvania 

 dropped to 32 degrees below zero last 

 winter. The house is a good one as 

 regards construction. The boiler has 

 nearlv double the needed capacity. 



E. B. F. 



The sketch shows a house 20x80 feet, 

 with wooden walls three and one-half 

 feet high. It is heated by means of 

 four 2-inch flow pipes under the ridge 

 and two 2-inch returns under each of 

 the side benches. This would be suf- 

 ficient to heat the house to 50 degrees, 

 but, with the present boiler, which is 

 said to be of double the required ca- 

 pacity, it would be more economical 

 of fuel if an additional return were put 

 in on each side of the house, making 

 six returns and four flow pipes. 



Really the plan of placing four 

 2-inch flows in the peak is not an 

 economical one. A better way would 

 be to run a 2%-inch flow pipe on each 

 plate and eight 2-inch returns under- 

 jieath. « ,' ,, « ,■, -»v
