residence. The hall is 10 x 45 feet and 

 eleven feet to the ceiling. It has two 

 exposed doors and two oval windows. 

 How many radiators will be needed 

 to heat this hallf - 



I wish to use 2-inch flows and IV^- 

 inch returns in each house. House No. 

 1 has now one 2-inch flow and ten 

 1%-inch returns; No. 2 has one 2-inch 

 flow and eight 1%-inch returns. Nos. 3 

 and 4 were built this season and are 

 not yet piped. I expect to build an- 

 other house in the fall, the same length 

 as the present ones. In this part of 

 Tennessee the outside temperature 

 seldom falls below zero. J. F. C. 



It is difficult to estimate the radia- 

 tion required to heat the hallway, from 

 the data given. Two or three radiators 

 should be used and these should have 

 a combined radiating surface composed 

 of as many square feet as there are 

 feet of exposed glasa*, plus the number 

 of feet of wooden wall space exposed 

 to outside air, or one-half the wall 

 space if the rooms are not directly ex- 

 posed to cold air, and plus the cubic 

 contents of the room. 



While it would be better to use 2%- 

 inch pipe for the flows and 2-inch for 

 the returns, good results can be se- 

 cured with the sizes mentioned. By 

 using two 2-inch flow pipes, not more 

 than six 1%-inch returns will be needed 

 in house No. 1. In house No. 2 use 

 two flows and eight 1%-inch returns; 

 house No. 3 should have three 2-inch 

 flows and ten 1%-inch returns and 

 house No. 4 should have one 2-inch 

 flow and four l^^-inch returns. To

MOREHEAD STEAM TRAPS 



fl The installation of a Morehead Betum Steam Trap in a 

 •^ Greenhouse is absolute evidence of progressiveness on the 

 part of the florist.. 



fl It is further evidence of good management, for the " More- 

 ^ head" is an investment m both satisfaction and economy. 



fl The majority of florists are using Morehead Traps.
