CHANGE TO HOT WATER. 



I am sending you a sketch of a small 

 greenhouse 10x15 feet, having eighteen 

 inches of glass in each wall and the 

 south gable being entirely of glass. 

 The north end is protected by the boiler 

 room. I want to maintain a heat of 55 

 degrees in zero weather. The house is 

 piped for steam, but I wish to use hot 

 water this winter, and then revert to 

 steam in the spring to heat the house 

 and coldframes. How could I pipe the 

 house so as to use the li4-inch pipe for 

 returns, with 2-inch mains? Can I 

 change the steam boiler to use hot water 

 heating? L. E. N. — Mich. 



The sketch shows the present piping 

 to consist of two 1%-inch overhead flow 

 pipes and four 1^4 -inch returns. This 

 radiation will be about right for heating 

 the house with steam, but will need to 

 be considerably increased if hot water 

 is to be used. 



For hot water radiation, use two 

 2-inch flow pipes, either on the wall 

 plates or along the middle of the sash- 

 bars, and, with each of these, supply a 

 coil of four 1*4 -inch return pipes under 

 the benches. Run all the pipes downhill 

 and connect the highest point in the flow 

 pipe with the expansion tank. Use two 

 2-inch pipes for the main returns. 



To use this radiation for steam, an 

 automatic air valve will be required 

 in the header at the lower end of each 

 coil, with valves at each end of three 

 of the returns in each coil, so that they 

 can be cut out as desired. 



The only change required in the boiler 

 will be the removal of the safety valve. 

 To change back to steam, disconnect 

 the expansion pipe and attach the 

 safety valve to the highest point in the 

 flow pipe. 



WATER BOILS OVER. 



I am having trouble heating my green- 

 house, which is 10x28 feet, with an 

 addition on the side 10x28 feet. I have 

 a hot water boiler rated at 450 feet, with 

 3-inch openings. I have under each 

 bench 120 feet of 1%-inch pipe, six 

 pipes to the coil. Each coil is twenty 

 feet long. They are fed by one 2-inch 

 main, which runs along near the roof, 

 and 1^-inch branches are taken off at 

 the far end. The coils are on a level 

 with the top of the boiler. They slope 

 toward the boiler and are connected with

it by 2-inch pipe. The expansion tanks 

 are in the top of the house, resting on 

 the flow, and are connected with the 

 return near the boiler. 



I cannot get the place warm enough 

 in cold weather. When I open the drafts 

 the water boils over. What is the 

 trouble? The circulation seems to be 

 good, but the water goes over the top all 

 the time. The addition on the side has 

 100 feet of 1^4 -inch pipe in the coil, 

 fed by a 1-inch branch taken from the 

 1^-inch pipe that supplies one of the 

 coils in the main house. Do you think 

 1-inch large enough for that coilf I 

 think that I should put 3-inch pipe in 

 the boiler and take another 2-inch flow 

 and run it on the side opposite the 

 present 2-inch flow, connecting with the
