The

Is the most efficient boiler built. 



Has the longest fire travel. 



Has thin waterways. 



Has water front, back, sides 

 and top. 



Made of boiler plate, not cast 

 iron.

either under the ridge or the south 

 purlin. Then place coils of four 2-inch 

 ^W pipes on the side walls, or under the 

 side benches, and distribute the other 

 four returns under the middle bench. 



We do not recommend the use of 1%- 

 inch returns for hot water in houses 

 as long as seventy feet, and would only 

 use them with a generator. For an 

 open-tank system, if we were to use 2- 

 inch flows in a greenhouse having the 

 glass area of the one under considera- 

 tion, we would suggest the use of at 

 least four 2-inch flows and would prefer 

 five. However, with a generator it 

 will be possible to use three 2-inch flows 

 and fifteen 1%-inch returns. By car- 

 rying the water under pressure, by use 

 of a generator, it will be possible to 

 make a considerable reduction in the 

 amount of radiation needed, but it will 

 not be so economical of fuel. 



For heating to 60 degrees, with hot 

 water, a greenhouse 16x70, with twelve 

 feet of glaflS in the side walls, we would 

 select a boiler rated at 750 square feet 

 of radiation.

 runs east and west, with the office, 12x

 at the west end. I shall heat all except 

 the storeroom, which has a cellar seven 

 feet deep for the boiler. The outside 

 temperature . has been known to drop 

 as low as 35 degrees below zero here. 

 How large a boiler will be needed T 

 What sizes of pipe should be used for 

 the flows and coilsf How many leet 

 of radiation will be required? Do you 

 think it would pay to install a closed

 doing sof What should be the height 

 of the chimney and the size of the flue?

 nothing to show the amount of glass,
