Greenhouse Heating. 



There are those who afl&rm that, after 

 all is said and done, the second-hand 

 boiler flue still is the ideal for greenhouse 

 heating. 



You know there will be a fuel famine 

 ia the^ winter. Well, don't be one of 

 those who are caught. Now is the time 

 to protect yourself. 



WATES BOILS OVEB. 



We are heating two houses, contain- 

 ing 5,000 square feet of glass, with 

 2,SK) feet of 2-inch pipe for radiation. 

 There are two 3-inch flows and two 3- 

 inch returns to the boiler. It is an 

 upright boiler, with plenty of capacity. 

 As an expansion tank we use a large 

 storage tank, which is fifteen feet 

 above the bottom of the boiler. A 1- 

 inch pipe, running from the bottom of 

 the boiler to the tank, is used for fill- 

 ing the boiler and as an expansion pipe. 

 In starting a quick fire and raising the 

 water to 100 degrees, the boiler is 

 nearly emptied and nearly all the water 

 is forced into the tank above. Is there 

 any danger of explosion and is there 

 any way of overcoming this trouble! 



W, S. 



For 5,000 square feet of glass it will 

 be well to use 1,700 feet of radiating 

 surface for 60 degrees, or 1,250 feet for 

 50 degrees. The question does not state 

 what temperature is desired, or whether 

 the flow pipes are carried through the 

 house so as to afford radiation. When 

 the water in the boiler behaves as de- 

 scribed, there is certainly something 

 wrong with the arrangement of the 

 piping. It is probable that much of 

 the trouble would be avoided if the 

 piping could be arranged so that the 

 flows would run downhill, after rising 

 from the boiler as nearly vertically as 

 possible to what would be the highest

point in the system, and from this 

 point a 1%-inch pipe should be run to 

 the expansion tank. This would do 

 away with the necessity for air valves 

 and there would be no trouble from 

 the water boiling over as described. 



BOILEB SCALE. 



Is there anything we can put in our 

 boiler to destroy the coating of lime on 

 the interior, caused by the hot water? 

 It is a tubular steam boiler. M. & J. 



There is a considerable number of 

 concerns through the United States 

 manufacturing what the trade knows as 

 boiler compounds. One of these com- 

 pounds that is used satisfactorily by a 

 number of florists is called Solventene 

 and is manufactured by the Northern 

 Chemical Co., Cleveland, O. If you 

 write to them, tell them where you ob- 

 tained the address, as they should be

OBEENHOUSE AND DWELLING. 



I am building a small propagating 

 house, 12x60 feet, nine feet to the ridge 

 and five feet to the eaves. The side 

 walls contain three feet of glass and 

 two feet of concrete. One end is glass. 

 The roof is even-span, with 8-foot sash-

bars. The house runs north and south, 

 with the boiler pit at the south end and 

 two feet lower than the floor of the 

 greenhouse. 



I have planned to run a 2%-inch flow 

 up to within twenty inches of the gable 

 and then divide into two 2-inch flows, 

 passing along under the ridge to the 

 north end, where one flow will branch 

 down to either side, into three 2-inch 

 returns under the bench on the east side 

 and three returns on the west side wall, 

 as the west half of the house has a 

 solid bed, one foot high. The other 

 2 -inch ridge flow will drop to the gp'ound 

 level and pass under the floor of the 

 dwelling, to heat three rooms there. The 

 rooms are all on the first floor and are 

 8x8, 8x12 and 14x20. They will be heat- 

 ed with two radiators. The expansion 

 tank is to be placed at the highest 

 point, at the south end, where the 2%-
