Greenhouse Heating. 



Subscribers are invited to write the 

 editor of tiie Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of grc^en- 

 houses, the i)iping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each article adver- 

 tised in this department of The Review 

 is good, and the advertisers sell them on 

 their merits. 



RETURN PIPE UNDER WALK. 



Kindly enlighten us as to the follow- 

 ing: We have two houses, and, on ac- 

 count of soil conditions, are not able 

 to sink the boiler below the ground 

 level. We have a hot water heating 

 system, with a Kroeschell boiler. We 

 do not wish to run the return pipes 

 across the walks at the boiler end of 

 the houses at a height where they would 

 interfere with walking through the 

 houses, and we are in doubt whether it 

 would be satisfactory to drop the re- 

 turn pipe to the ground and raise it 

 again to get it into the boiler. W. R. 



While it would be better to avoid the 

 trap in the return pipe, yet if the sys- 

 tem is run downhill to the point where 

 the rise in the return is made, there 

 should be no difficulty in securing a 

 good circulation with the return drop- 

 ping under the walk as described. 



TWO IOWA HOUSES. 



I am building two connected green- 

 houses, each 21x75. The houses run 

 east and west, with the boiler house 

 at the east end. The exposed sides of 

 the houses are six feet high, with three 

 feet of glass and board siding below. 

 The west ends are exposed. I will 

 grow carnations in the north house, 

 and will use the south house for all 

 kinds of pot plants, with some roses 

 and palms. The boiler pit is" five feet 

 below the level of the ground and the 

 ground slopes one foot to seventy-five 

 feet toward the east. T will have two 

 .>foot benches in the middle and two 

 3-foot benches on the side in each 

 house. Will you please tell me how 

 much piping is needed and the proper

are devoid of all unnecessary 



mechanism. 



Every part designed, manuf actnrei 



and assembled with the idea of 



permanence foremost. 



Every tilt of the trap shows that 



it's working — draining every drop 



of condensation from the heating 



system and automatically returning 



it to the boiler— no pumps— no 



trouble. 



Condensation is the jmrest kind of boiler feed water. Don't waste it. Return k

Two Tanks vs. One 



Only the small tank moves and by this construc- 

 tion we have overcome the objections to the large ' 

 tilting traps with tlieir large trunnions, causing 

 excessive wear and friction. With the 



English Steam Traps 



all valves and worlcing parts are made of bard brass 

 and are on tbe outside — therefore, easily accessible. 

 They never stick. Always free acting.
