^eenhoase Heating. 



BOILER HAS AMPLE CAPACITY. 



I have a small steam boiler, contain- 

 ing twenty-five 3-inch tubes, six feet 

 long. The shell is three feet in diam- 

 eter and the grate surface is two feet 

 ten inches by three feet four inches. 

 Is this boiler large enough . to heat a 

 greenhouse 20x75? Will you also give 

 instructions for the piping of the house? 

 I wish ,to maintain a temperature of 

 60 degrees in zero weather. The loca- 

 tion is a somewhat exposed one. 



D. A. M.— Pa. 



A steam boiler of the size described 

 would be rated at twelve horsepower 

 and would readily handle 800 to 900 

 square feet of radiation, while less than 

 400 square feet will be required to heat 

 a house 20x75 to 60 degrees. The prin- 

 cipal diflBculty is likely to come from 

 the night firing required to keep up 

 steam in zero weather. However, the 

 fact that there is reserve power in the 

 boiler will aid in maintaining steam. 



If there is no glass in the sides of the 

 house, and if it is of fairly warm con- 

 struction and the roof glass is tight, we 

 would expect to keep up the tempera- 

 ture desired by using one 2%-inch over- 

 head main, carried to the farther end of 

 the house about three fee* below the 

 ridge, and eight 114-inch returns, either 

 in coils on the walls or partly under the 

 benches. The boiler should be set so 

 that the water level will be at least two 

 feet below the lowest part of the re- 

 turns, and three or four feet would be 

 better. If this can not be done, a steam 

 trap should be used. There should be 

 an automatic air vent at the lower end 

 of each coil. All pipes should have 

 a fall of about one inch to ten or fifteen 

 feet. The main return should be 1%- 

 inch, and 114-inch pipes should be used 

 to connect the coils with it. 



INSTALLING A OENEBATOR. 



In The Eeview of January 20 we 

 read an article entitled "Too Much 

 Night Firing, ' ' in which there was a 

 discussion of mercury generators. We 

 have a hot water system that will main- 

 tain a temperature of 55 degrees when 

 the outside temperature is 20 degrees 

 below zero, without being forced, but 

 the outdoor temperature here often 

 drops to 40 degrees below zero for a 

 night or two, and we find it difficult 

 to heat one of our greenhouses during 

 these cold spells. We have a Honey- 

 well generator, but the plumbers do not

Because of their proyen sclentlflcally perfect con- 

 ■tmctlon. Metropolitan Patented Boiler* will heat a 

 Kiyen amount of water quicker, with lets fuel and 

 leaa attention than any other boiler on the market. 



The remarkable heatingr efficiency and qaick 

 ■teaming qnalitles of these boilers are due to their 

 large and eflectiye heatiDfr surface. 



Just a few points of Metropolitan Patented Boiler 

 merit:— Smooth, perfect finished castings. Push nip- 

 ple connections. Large fire box, proyidlng ample 

 combustion chamber, and permitting a sufficient 

 charge of fuel to require attention only at long inter. 

 yals. Deep ash pit, making the removal of asbea a 

 Blight task. Large flues, making the boiler eaay to 

 clean. Orates that are made for hard usage and long 

 service. And above all, they are Fuel Saving, not 

 Fuel Wasting. 



We also make soft coal boilers which are smoke, 

 less, and save SO per cent in coal.
