Greeahoose Heating. 



CAPACITY OF BOILER. 



How much greenhouse glass can be 

 carried on a boiler of eighty horse- 

 power, steam being used and 60 de- 

 grees to 70 degrees required in the 

 climate of western New York? How 

 small a range of glass could be operated 

 economically on this boiler ? J. C. T. 



The eighty horse-power boiler should 

 be adequate to carry about 35,000 square 

 feet of glass at a temperature of from 

 60 degrees to 70 degrees. I do not 

 think it would be economical to use a 

 boiler of this size on a steam basis with 

 less than 15,000 to 20,000 square feet of 

 exposure. This would make about one- 

 half a load. L- C. C. 



FIRES HARD. 



There seems to be something wrong 

 with our heating apparatus, as it fires 

 too hard in severe weather. We use a 

 Boyuton No. 7 sectional water beater 

 placed below the pipes. The flow is 

 through five feet of 3-inch pipe to a 

 2-inch tee, from which three 2-inch pipes 

 rise one inch in ten feet to the far end 

 of the houses and fall back on the oppo- 

 site side to the return tee. Our two 

 houses are 12x35 and 14x40, side walls 

 five feet, nine feet to the ridge. Each 

 house is piped separately from the boiler. 

 The expansion tank is over the boiler. 

 In weather as cold as zero it is nearly 

 im]K>ssible to keep the houses above 45 

 degrees, firing with Kanawa coal and 

 wood. Have we enough pipe and boiler 

 capacity? W. B. 



The small house, 12x35 feet, in order 

 to maintain a satisfactory temperature 

 during the severe weather should be pro- 

 vido<l with ten lengths of 2-ineh pipe. If 

 the piping is all under the benches a 

 2-inch flow and four 2-inch returns on 

 each side will be satisfactory. 



The house 14x40 feet should have 

 eleven lengths of pipe. If the piping is 

 arranged under the benches a 2-inch flow 

 and five 2-inch returns on the most ex- 

 posed side, with a 2-inch flow and four 

 2-inch returns on the other side, will do 

 the work. I do not have the rated capa- 

 city of the boiler you are using, but the 

 boiler to do the work should not be rated 

 at less than 1,000 square feet of radia- 

 tion. It. C. C. 



VIOLETS ON TABLES. 



I have built a violet house 14x50 with 

 4-foot walls and with three benches three 

 feet high. The house extends east and 

 west. There is a 7-inch cement wall on 

 the north side and it is double-boarded 

 with building paper on the south side. 

 I have a Wilks hot water heater and am 

 ready to put in the pipes. I will be 

 gratified for your advice regarding the 

 forrect position, etc. The Wilks Co. sent 

 me a dravring showing the pipes under 

 the benches. Is this right for a violet 

 house or should they be on the side walls 

 above the benches? How much lower 

 should the boiler be than the flow pipes? 

 Should the flow ascend? If so, how 

 much? I am picking up a great deal of 

 information from the Review, and con- 

 sider it my beet investment.

tain the required temperature for violets. 

 But under the circumstances I will not 

 guarantee satisfaction, because the type 

 of bench construction used is not well 

 adapted to the work in hand. The most 

 successful violet growers use solid 

 benches and overhead heat. My ex- 

 perience with violets on elevated benches, 

 even .with overhead heat, has not been 

 altogether satisfactory. 



I shall advise the use of coils on the 

 side walls but do not think they will give
