there divide it into two 2'/^ -inch pipes, 

 one going to the north and one to the 

 south end of this house, and there divide 

 to enter each of the coils under the 

 benches, as returns. This arrangement 

 will give you a somewhat quicker flow 

 than you now get. The next thing is to 

 connect the expansion tank to the main 

 return within twelve inches of where it 

 enters the boiler, and by the use of a 

 %-inch pipe carry it eighteen or twenty 

 feet above the highest point in the sys- 

 tem ; or, if you have an elevated tank for 

 supply, make direct connections with it, 

 provided it is not over twenty or thirty 

 feet above the ground. Tlit'se modifica- 

 tions, if your boiler has a rated capacity 

 of 1,500 feet, should give satisfaction.

I have a three-qnarter-spau house, 20x 

 50 feet, running east and west, with a 

 boiler-room at the 'east end of the house. 

 [ have a Mercer boiler, No. 1, with nine 

 sections. Our winter temperature here 

 ranges from above zero to 15 degrees 

 below and occasionally 20 degrees below. 

 [ have been heating with hot water and 

 wish to continue to do so. I now have 

 four 2-inch flows and ten 2-inch returns. 

 My north flow has three 2-inch returns, 

 suspesded on the north wall. My south 

 flow has three 2-inch returns, suspended 

 on the south wall. The other two flows 

 have each two 2-inch returns un<lor the 

 eenter benches. 



Now, this arrangement does tlu' heat- 

 ing very well, but the four flows run 

 overhead and I desire to get them out of 

 the way and T wish to know if ono .S-inch

flow, up under the ridge, will do the 

 work as well or better. Each set of re- 

 turns enters the boiler-room in one 2-inch 

 pipe, making four 2-inch returns as they 

 enter the boiler, 'fhese I cannot change, 

 as the boiler is tapped for 2-inch pipe 

 only on the returns, while it is tapp6d 

 for four 2-inch flows and one 3-inch flow, 

 if I can use one 3-inch flow for all and 

 run it under the ridge, will it be all right 

 for me to put in a tee about three feet;
