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 Eeview is a good boiler, and 

 the advertisers sell them on their merits. 



A MASSACHUSETTS HOUSE. 



We have a house 35x140, sides four 

 feet high and sixteen and one-half feet 

 to ridge. Please inform us how many 

 square feet of glass there are in this 

 house and what would be the best way 

 to pipe it for steam and hot water 

 combined. If heated by hot water, 

 what is the best method of forced cir- 

 culation T Massachusetts climate. 



F. B. P. 



There would be not far from 5,880 

 square feet of glass in the roof of the 

 house described, besides some 220 feet 

 in each exposed end. "When a house is 

 to be heated with a combined steam 

 and hot water system, it is generally 

 advisable to put in only so much pipe 

 as will be required to heat the house 

 with steam in the coldest weather and 

 then use it as a hot water system only 

 in mild weather, when the radiation is 

 sufficient to secure the desired temper- 

 ature. While it is always advisable to 

 use 1^-inch pipe for a steam system, 

 for a combined steam and hot water 

 system it is generally better to use 

 1%-inch pipe for the returns in a house 

 more than 100 feet long. 



The letter does not state what tem- 

 perature is desired, but, for 60 degrees, 

 three 2% -inch flow pipes and twelve 

 1%-inch returns would answer for 

 steam and could be used for heating 

 the house with hot water when the 

 temperature outside is 20 degrees above 

 zero. By connecting a mercury seal 

 to the expansion pipe the temperature 

 of the water could be raised to nearly 

 that of steam and the system could

RETURN TRAPS 



SAVK THE MOST VALUABLE PART OF CONDKNSATION-ltS HEAT. 



They automatically 



return all the condensa- 

 tion from the steam lines 

 directly to the boiler at 

 almost evaporation 

 temperature — less coal 

 is required to convert it 

 into steam again — hence 

 a great saving is effected.

 the ends contract until it will readily pass 

 into the flue. Then by turning the handle 

 in an opposite direction the cleaner is 

 gradually expanded until it fits the tube 

 perfectly; the brush following leaves the 

 tube absolutely clean.
