Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Review is a good boiler, and 

 the advertisers sell them on their merits. 



BOILEK AND STACK. 



I wish to build two greenhouses 21 x 

 160 feet, five feet to the gutter and 

 twelve feet to the ridge, which should 

 average about 60 degrees in the climate 

 of Ohio. Will some one kindly tell me 

 what size boiler will be necessary, using 

 steam heat, and how high the stack 

 should be? J. & R- 



Any boiler rated at 5,000 feet would 

 be all right. It will take about 4,000 

 running feet of 1^4 -inch pipe, but I 

 would get a boiler rated at 5,000 feet. 

 A stack two feet in diameter and forty 

 feet high will serve. F. R. 



YOKma BOILEES. 



Wc have two fire-box boilers, which 

 will be bricked in, and we wish to con- 

 nect them and run them together as a 

 battery. We want to arrange them so 

 we can run either one independently. 

 How can we make proper connections? 

 In connecting two boilers to one smoke- 

 stack, which is the better way — to run 

 two separate smoke pipes to the stack 

 or connect the two pipes with a Y and 

 enter the stack with one pipe? 



W. & K. 



It is not always an easy matter to 

 connect boilers so they will work well. 

 The common way of arranging the 

 smokestack when one is used for two 

 boilers is to set the chimney or stack 

 to one side of the boilers and connect 

 the two by a breeching, i. e., a pipe 

 placed horizontally, into which the 

 gases from both boilers enter, and this 

 is then connected with the chimney. Be- 

 sides this, each boiler should be pro- 

 vided with both steam and water 

 gauges. Yoke the two together at the 



10 Hours Without Firing 



even in severely cold weather, is a common 

 experience with those growers who use the

to keep the temperature even and con- 

 tinuous, making night firing unnecessary.

top, with j)roi)prl_v valvcd (•oiiiiections 

 with the main, to allow either to be used 

 independently, and connect them with 

 the common return, using a swing check 

 between the boiler and the main return 

 in each case, besides a gate valve. 

 Lower the boilers just as far as possi- 

 ble below the pipes in the houses. The 

 greater this distance, the less trouble 

 will be experienced by water baci<ing 

 up in the heating pipes. F. R. 



THE FUEL MARKET. 



A somewhat new face was put on the 

 coal situation last week by the action

A Steady 

 Pressure 



will always 

 be main- 

 tained in 

 Your steam pipes, no matter 

 how the pressure at the boiler 

 fluctuates, if you equip your 

 main lines with these valves. 

 Garry 40 or 50 pounds pressure 

 on the boiler, set the 



Hughson 

 Regulating Valve 



to carry 5 or 10 pounds on the 

 line and you will always have a 

 reserve in case of a sudden drop 

 in temperature. This valve 

 saves both fuel and worry. Ask 

 for catalogue and particulars.

of the general committee of hard coal 

 miners, who turned down the arrange- 

 ment their subcommittee had made with 

 the mine operators. At present the hard 

 coal industry is up in the air — there 

 is no immediate prospect for the re- 

 sumption of production. Of course an 

 agreement may be reached at any mo- 

 ment, but for the present the negotia- 

 tions, or the negotiators, appear to be 

 at a deadlock.
