(Ireenhouse Heating. 



HEATED WITH 4-INCH PIPES. 



Enclosed you will find two diagrams 

 of my greenhouses. You will notice 

 that in the two connected houses the 

 two pipes running from the boiler are 

 fed by one main. Both pipes ascend to 

 the farther end of the house and the 

 one marked E. P. descends to the boiler. 

 All are 4-inch water pipes. Is the pip- 

 ing properly installed? In the other 

 house there are also two 4-inch pipes, 

 both fed by a single main, but in this 

 ■case both pipes descend to the boiler, 

 after rising to the highest point at the 

 farther end. I am located in north- 

 western Missouri. L. M. S. 



One of the sketches shows two houses, 

 each 20x40 feet, with one 4-foot wall 

 exposed in each house. The heating is 

 done by two 4-inch flow pipes, which 

 run along the exposed walls in each 

 house, with a 4-inch return alongside. 

 The temperature desired is not stated, 

 but it would not ^ib possible to main- 

 tain a higher tempwature than 40 de- 

 grees when it is zero outside, and to 

 obtain that temperature along the inner 

 wall of the houses the return pipes 

 should be carried across the ends of 

 the houses and back to the boiler along 

 the side opposite the flow pipes. For 

 €0 degrees run three flows and three 

 returns in each house. 



The other sketch shows a house 20x50 

 feet, which has two flows and two re- 

 turns put in as recommended above. 

 This would give perhaps 45 to 50 de- 

 grees. The piping would be improved 

 if the highest point in the system were 

 near the heater, with a fall throughout 

 the length of the pipes. 



EXPANSION TANK BOILS OVEB. 



I have recently installed a small cot- 

 tage hot water heater in a small house 

 built for special use, and piped as fol- 

 lows: The house is 14x18x24 feet. It 

 has a shingle roof, board sides and ends. 

 In each of the two sides there are four 

 sashes, each 3x6 feet, and there are 

 two windows in each end. We need a 

 temperature of 85 degrees in the day- 

 time and 80 degrees at night. In this 

 part of Washington state the outside 

 temperature never falls below 20 de- 

 grees above zero. The trouble with the 

 system is that we have to watch the 

 boiler carefully or the water will boil 

 out through the expansion tank. 



The boiler is of the saddle type, with 

 a firebox 20x22 inches. The bottom of 

 the boiler is two feet lower than the

return coils. We started with a 2-inch 

 flow, raising it to the highest point, 

 right over the boiler, and then con- 

 tinued with one 2-inch line placed under 

 the eaves on each side and dropping 

 eight inchea in the length of the house. 

 At a point near the end we took a side 

 leader, l^^-inch, which we connected 

 with two 1%-inch returns under the 

 benches. The other coils are placed on 

 each side wall, three 1%-inch pipes 

 forming the coils and dropping toward 

 the boiler with a fall of two inches in 

 ten feet. All the coils — that is, three 

 1^-inch on each side and two 1^-inch 

 under each bench — connect with a 

 2-inch return to the boiler. 



We first connected the expansion 

 pipe at a point on the return near the 

 boiler, but it boiled over and would 

 raise the water out of it until we had
