HEATING SASH HOUSES. 



We have three connected sash houses, 

 thirty-two feet high, with high side walls. 

 The houses run north and south. We 

 have been heating the west one from a 

 hot water boiler at the south end, by 

 four 2-inch pipes around the sides, un- 

 •lerneath the benches. Can you tell us 

 how to connect the boiler with the other 

 two houses t We would like the same 

 heat in the second house and only half 

 as much in the third; we should also 

 like to be able to shut oflP all the heat 

 from the third house in the coldest 

 weather. Is there any way we can ar- 

 range this, as there is no building in 

 front of the last two houses? Mass. 



By sacrificing a little heat and placing 

 that much extra work upon your boiler 

 you can heat all three of your houses 

 from the one boiler, even if you have 

 no shed over the end. An independent 

 riser can be carried from the boiler to 

 supply these two houses. A 2-inch or 

 2^-inch pipe wiU be suflScient. It can 

 be carried from the boUer to the high- 

 est point under the ridge of house No. 2 ; 

 there supply a 2-inch riser to heat house 

 No. 2, which can be piped with a 2-inch 

 flow under the ridge, returning by two 

 2-inch pipes under each side bench or 

 along side walls. House No. 3 can be 

 heated by carrying the riser on the out- 

 side from the ridge of house No. 2 to 

 the ridge of house No. 3 and there sup- 

 ply a 2-inch flow, which can be returned 

 by two 2-inch returns, one under each 

 side bench. 



In order that this house may be thrown 

 out of commission durinc Revere weather 

 it will be necessary to place a gate valve 

 on the main flow pipe in house No. 2, 

 so as to cut off the flow to house No. 3. 

 An air valve should be placed on this 

 flow pipe where it makes the angle under 

 the ridge in house No. 3, or just behind 

 the gate valve in house No. 2. The main 

 return, which can be carried through 

 the houses on the surface of the ground 

 back to boiler, should also be provided 

 with a gate valve to cut off the return 

 from house No. 3, but so as not to in- 

 terfere with the circulation in house No. 

 2. The main return in house No. 3 

 must also be provided with a i^-inch or 

 %-inch opening into which a hose bib 

 or nipple carrying a valve shall be 

 placed. This outlet should be at the 

 lowest place in the return in house No. 

 3 and as near as possible to the gate 

 valve. When house No. 3 is to be put 

 out of service close both gate valves, 

 open the air vent in the flow pipe and 



then open the drain valve in the return, 

 so as to drain all the water out of the 

 pipes in the house to be left cold. 



The riser between the ridges of houses 

 No. 2 and No. 3 should be covered with 

 asbestos pipe covering and over this 

 build a box so arranged as to protect 

 the covering from the weather. I have 

 used galvanized gutters of proper size as 

 a housing for exposed pipe covered with 

 asbestos wrapping. L. C. C. 



PRESSURE SYSTEM. 



Kindly give plan and particulars of 

 pressure system. How many square feet 

 of exposed sash can be heated by one foot 

 of hot water radiation, maintaining a 

 temperature of 45 degrees at night when 

 outside temperature is 15 degrees to 20 

 degrees below zero? How many more 

 square feet could be heated under same 

 conditions with pressure system, tank 

 raised to an altitude of 8 to 10 feetf 

 Would any precautions be necessary to 

 prevent the water in such a tank freez- 

 ing? 



In a house 20 feet wide, heating pipes 

 on side walls, would it be necessary to 

 have pipes arranged to heat the end of 

 the house exposed to west winds? 



Wm. K. 



I take it for granted that you refer to 

 hot water under pressure. This simply 

 means that the water in the pipes is 

 placed under pressure either by use of an 

 elevated expansion tank or by connecting 

 the system with a general supply having 

 considerable pressure. City water works 

 pressure is sometimes used when the pres- 

 sure does not exceed 30 or 40 pounds. It 

 is estinsated that hot water either under 

 pressure or in open circuit at 160 degrees 

 temperature will carry 4.5 square feet of 

 glass at 45 degrees for each square foot 

 of radiating surface. If the water is 

 heated to 180 degrees each foot of radia- 

 tion will carry 5.4 square feet of glass at 

 45 degrees under the conditions you re- 

 cite, the area heated varying in propor- 

 tion to the heat of the water. The advan- 

 tage of the pressure system lies in the use 

 of smaller threaded pipes instead of the 

 cumbersome expensive cast-iron pipes and 

 in the fact that the water in such pipes 

 can be carried at a higher temperature 

 than in those not under pressure. Water 

 in open circuit cannot be heated above 

 212 degrees F., while water under pres- 

 sure can be forced beyond this point. 

 The pressure system is an advantage in 

 cold snaps when it is necessary to force 

 the fircw. Then, too, this plan admits of 

 a combination plant which can be used

for hot water during mild weather, and 

 as a steam plant during severe weather. 

 It is well to have this expansion tank 

 well piotected in severe climates as hot 

 water pipes freeze more readily than cold 

 water pipes. 



Whether or not pipes should be car- 

 ried across exposed end of 20-foot house 

 all depends upon the amount of radiation 

 carried in the house and its distribution. 

 Under normal conditions it would be best 

 to turn the manifolds used on the side 

 walls across the exposed end as well.
