Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Beview is a good boiler, and 

 the advertisers sell them on their merits. 



TWO CONNECTED HOUSES. 



We are building two houses, each 

 30x150 feet. The houses will be con- 

 nected. They will be built on ground 

 that slopes to the east. There is about 

 four feet of a drop in the 150 feet. The 

 boiler will be at the east end of the 

 houses. The walls of the houses are 

 six feet high and the ridge is thirteen 

 feet from the ground. We want a tem- 

 perature of 65 degrees at night and 70 

 to 80 degrees in the daytime, at 5 de- 

 grees below zero. There are four beds 

 on the floor, the full length , of the 

 house. How many 2-inch flows and re- 

 turns will be needed and where would 

 you place them to get the best results f 

 Where would you place the expansion 

 tank? We want to use the gravity sys- 

 tem, to help the flow of water. The 

 supply tank will be above the houses, 

 on the higher ground. What size of 

 feed pipe will be needed? What size 

 of boiler? H. B. 



Each of your houses 30x150 requires 

 sixteen lines of 2-inch pipe to supply 

 sufficient radiation to maintain the tem- 

 perature desired. It will be advisable 

 to use three lines in each house as 

 risers, and the thirteen returns in as 

 many coils as there are risers for each 

 house; that is, two coils of four pipes 



Awarded the Certificate of Merit 



at the National Flower Show. Boston. Mass.; and also received the universal approval of all 

 the visitors who examined it:; merits, the expression of the majority beintr 



"THAT IS THE BOILER I HAVE BEEN LOOKING FOR" 



The points of merit that appealed to the judges and the critical visitors were that the fire- 

 box is entirely surrounded by water, there being no brick work to require constant repair; 

 every part of the boiler is easily accessible for cleaning and oiling, which Is the most impor- 

 tant feature to b-> considered in purchasing a boiler that is idle during the summer months ; 

 all the castings, doors, grates, etc., are made double extra heavy.
