A NEW HAMPSHIBE EANOE. 



Will you please advise me as to the 

 b«Bt way of heating the houses that 

 Are outlined on the enclosed diagram 1 

 You will notice that houses No. 1 and 

 t, according to the diagram, meet at 

 tie boiler room, while houses No. 3 

 AKd 4 abut on No. 1 and run parallel 

 witk No. 2. In other words, houses 

 No. 2, 3 and 4 are crossed at the ends 

 by the boiler room and house No. 1. 

 Houses No. 1 and 2 are already built, 

 and piped as I have marked, but I 

 ^re got to put in a new boiler, and I 

 waat to build two more houses, Nos. 

 S and 4, as I have sketched them. la 

 the plan feasible? The 3-inch flow pipe 

 in No. 1 pitches down from the boiler 

 room as it now is. I thought I would 

 «k«jige it and make the highest point 

 at the farther end, putting in a ^-inch 

 ga« pipe to go up through the roof to 

 take care of the air. I should like to 

 be able to heat two of the houses, Nos. 

 t and 4, to 60 degrees in zero weather, 

 aad the others to 50 degrees. How 

 layge a hot water heater will be re-

quired, and how much and what size of 

 pipe! S. M. P. & S. 



From the sketch it would appear 

 that houses 3 and 4 are 11x50 feet, but 

 the size of the other houses is not so 

 clear. House No. 1 is fifty feet long 

 and is evidently not far from ten feet 

 wide. It is heated by means of one 3- 

 inch overhead flow and six l^-inch re- 

 turns. House No. 2 is thirty feet long 

 and is marked "20-foot rafters." It 

 appears to be a leftn-to house, and will 

 be so considered. It'iB iieated by one 

 3-inch flow and eight 2-inch returns, 

 which should furnish 50 degrees. 



The flow pipe in house No. 1 is 

 larger than is needed for that house. 

 While it would hardly be able to han- 

 dle houses 3 and 4 in addition, it would 

 supply those houses if a 2 1^ -inch flow 

 were put in for house No. 1. If this

is not done, a 3-inch flow should be put 

 through house No. 1 to supply houses 

 3 and 4. This could be reduced to 2V^- 

 inch after taking off a 2%-inck 

 pipe to supply house No. 3. For heat- 

 ing houses No. 3 and 4 to 60 degrees, 

 use one 214-inch overhead flow and 

 seven 2-inch returns in each house. 



A boiler for the four houses will re- 

 quire a rating of about 1,000 to 1,200 

 square feet of radiating surface.
