Greenhouse Heating. 



As f orecast-4iL this column a fortnight 

 ago, buckwheat, the grade of anthracite 

 coal burned by many florists in the east- 

 ern section, has turned weak in the tide- 

 water markets. No. 1 has sold at $2.15 

 or lower and both No. 2 and No. 3 liave 

 been bought below the circular, or at 

 $1.85 to $1.90 for the former and $1.60 

 for the latter. 



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. 



It is interesting to note that of the 

 anthracite coal mined in 1911 twenty- 

 five per cent was of the steam grade used 

 by florists, among others. The figures 

 as prepared by the U. S. Geological 

 Survey are: Total production, 80,732,013 

 long tons; sizes below pea, 20,405,396 

 long tons. Of the latter 9,832,519 long 

 tons was No. 1 buckwheat. A long ton 

 is 2,240 pounds, but it isn't what the 

 florist buys; he buys by the short ton, 

 2,000 pounds, frequently getting a still 

 shorter ton, though shrinkage is not now 

 so great as it once was.

90 and fourteen feet to the ridge, with 

 a southern exposure. .1 want a temper- 

 ature of 60 degrees when the outside 

 temperature is 5 degrees below zero. 

 My location is southern New Jersey. 

 Can you tell me the correct size of fur- 

 nace to fit fifteen grate bars, four and 

 one-half feet long? What size of water 

 pipes would be needed above the fire, 

 and how should they be laid to have 

 one row on the north side and one row 

 on the south side? What size of pipe 

 would be best for the outflow? Should 

 it run to the eaves and return under 

 the benches, or should all the pipes be 

 under the benches? I have seen some 

 houses fitted up with 4-inch pipes and 

 all of them seemed to be under the 

 benches. 



Should the coil in the furnace be con- 

 nected with manifolds or return bends! 

 Would a distance of fifteen inches above 

 the fire be too close to the fire or too 



far away from it? I want the fur- 

 nace to have twenty-five to thirty 

 inches of space above the fire pipes, so 

 as to use the space occasionally for 

 burning odd pieces of clay. I am try- 

 ing to plan this so as to burn fancy 

 fern dishes, palm pots, etc., over the 

 pipes in the furnace, .ind to use coke 

 for fuel. Where and how should the 

 feed system be connected? W. J. S. 



Having had no experience in the mak- 

 ing of a kiln for firing pottery,' I can- 

 not tell exactly what the requirements 

 are. Ordinarily it will be found better 

 to buy one of the greenhouse boilers 

 on the market than to attempt to make 

 a pipe coil boiler. However, either 

 manifolds or return bends can be used. 

 If either of them are built up, there 

 will be less danger of their cracking, 

 owing to expansion, than when either 

 manifolds or bends in one piece are

Where There Is CondeHsation 



— 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.
