Where There Is Condensatioo 



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

 steam 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.

more than 250 feet of radiation will be

IN BBITISH COLUMBIA. 



We are building a greenhouse for gen- 

 eral purposes, one in which we may 

 grow lettuce, force bulbs, grow bedding 

 stock, propagate nursery stock, etc. 

 The house is 19x100 and has 6-foot 

 walls. In the center is a glass partition, 

 so as to provide for different tempera- 

 tures. On one side there is a lean-to, 

 extending the whole length, to be used 

 as a propagating house; this also has 

 the division in the center. The main 

 house has three benches. ^ What advice 

 would you give us on the heating sys- 

 tem? It will have to be a hot water 

 system. What size of boiler do we need 

 and how is the pipe to be placed? What 

 will be the best size of pipe? Any in- 

 formation will be thankfully accepted. 



C. V. A. 



The width of the lean-to is not stated, 

 but we shall consider that it is six feet, 

 and while the minimum winter tempera- 

 ture in j'our part of British Columbia 

 is not stated, we shall suppose that the 

 winter temperature does not drop lower 

 than 15 degrees below zero. For heat- 

 ing such a plant with hot water a boiler 

 rated for about 1,000 square feet of 

 radiation will be needed. 



In the way of piping, run one 2*4 - 

 inch flow on each of the wall plates and 

 another under the ridge. Connect each 

 of the flows on the walls with three 2- 

 inch returns, to be carried underneath, 

 and use the flow under the ridge to feed 

 two S-inch returns in the lean-to. This 

 should give 50 degrees. For 60-degrees 

 in the end nearer the boiler, take off 

 two additional returns on each wall, 

 from the wall flows.

I have a small greenhouse that is sit- 

 uated sixty feet away from my dwelling 

 house. Can I heat the greenhouse by 

 any method known to you, with the 

 heater in the cellar of my dwelling and 

 the flow pipes going underground to 

 the greenhouse and then rising into the 

 greenhouse? The flow pipe could not 

 be over two and one-half feet below the 

 surface and have any rise, owing to the 

 slope of the land, which has a gradual
