Where There Is Coodeosatioo 



— there is need for a Morehead Steam Trap. Condensation in 

 Bteam lines is akin to matter out of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your boiler without 

 pump or injector or make no charge for the trial. Obey that 

 impulse — write now.

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 Review is a good boiler, and 

 the advertisers sell them on their merits. 



CONSTRUCTION AND HEATING. 



I am thinking of building in the 

 spring a rose house 23x70 feet, to abut 

 against the west side of the engine 

 house and run west. The wall will be 

 of concrete, with about three feet of 

 glass above the wall. I expect to build 

 other houses on the north side later. 

 What I should like to know is: Would 

 it be best to have a long span on the 

 south side? Would it be necessary to 

 have ventilators on both sides in this 

 width of house t What would be the 

 best kind of benches to make? What 

 would be the best plan of piping for 

 hot water heatt What is the best size 

 of pipe? I can not get a good fall, so 

 as to put the return pipes under the 

 bench. State the number of pipes to 

 use to get a temperature of 65 to 70 

 degrees in zero weather, without crowd- 

 ing the boiler too hard. I shall put in 

 a new sectional boiler. Which is the 

 better to use, a wooden cap on top of 

 the glass, or putty f I shall also be 

 glad to receive any other information 

 you can give me. I am located in 

 eastern Michigan. F. V. B. 



While a long span on the south of 

 the rose house would give good results, 

 the general tendency is toward even- 

 span houses, for widths of thirty feet 

 and less. One row of ridge ventilators 

 will answer. Cement benches will be 

 the most durable and, if built at odd 

 times, will not cost much more than 

 wooden benches. If the benches are 

 not entirely constructed of cement, it 

 will be well to have the legs, at least, 

 either of cement or gas pipe. Some- 

 times light iron rails or iron pipe can 

 be obtained cheaply and they make 

 excellent stringers. Slightly ujod or 

 damaged lumber can often be picked

By simply turning the rod or handle, 

 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.

up at a bargain and might be used for 

 the bottom and sides of the benches, 

 but wooden benches, at best, will not 

 be really durable. 



To heat a house 23x70 feet to 70 

 degrees in zero weather will require 

 about 1,000 square feet of radiation.
