Greenhouse Heating. 



GAS AS FUEL. 



Ffeeling that the cost of heating our 

 plant is too high, we should like to 

 know whether there is a boiler in the 

 market especially constructed for gas 

 as fuel? We shall be much obliged for 

 any information along this line, as well 

 as for other people's opinions about 

 the most economical gas burners. 



C. F. C. 



I do not know of any boiler that is 

 especially constructed for burning gas 

 as a fuel, but almost any of them can 

 be used with gas, it being only neces- 

 sary to fit a gas burner to the boiler 

 and connect it up. 



HEATING WITH EXHAUST STEAM. 



Has any one of the commercial grow- 

 ers tried to heat greenhouses with ex- 

 haust steam from factories? There is 

 an electric light plant about 300 feet 

 distant from our greenhouses and the 

 only obstruction is a street. We could 

 get a contract for the exhaust steam at 

 small cost, if we were sure that the 

 plan would be practical. C. F. O. 



It is entirely practical to heat a 

 greenhouse with exhaust steam, if it 

 does not have to be carried more than 

 300 feet. Care should be taken to 

 have the pipes thoroughly insulated. 

 They can be run underground, through 

 sewer pipes or in grout conduits. 



TO IMPROVE THE CIECULATION. 



I would appreciate any information 

 on hot water circulation. The circula- 

 tion in my piping is too slow. I have 

 an open system. Would a change to a 

 closed system be the best remedy? 

 The boiler is not quite low enough. 

 The expansion tank is about five feet 

 above the boiler. When I run a good 

 fire it makes steam, stops the circula- 

 tion and forces the water through the 

 expansion tank. How would I have to 

 arrange the piping for a closed system? 

 There is a vent pipe »n the farther end 

 of each pipe. F- ■^• 



Before putting in a closed system, it 

 will be well to make several changes in 

 the present piping and give it another 

 trial as an open system, especially as 

 the changes suggested will be necessary 

 even if it is to be changed to a closed 

 system. I would suggest running the 

 flow pipes so that they will have a 

 slight slope from the boiler. Keep

these pipes, as well as the returns, as 

 high as possible. Connect the expan- 

 sion tank with the highest point of the 

 flow pipes and place the tank as high 

 as possible. 



If this does not do away with the 

 difficulty, close the system by putting 

 on safety and vacuum valves, or by 

 using a mercury pressure valve.

BOILER ON THE GROUND LEVEL. ' 



I should like to get a little informa- 

 tion in regard to our heating system. 

 We have five houses, running north and 

 south, each 14x120 feet, six feet to the 

 gutters and ten feet to the ridge. Our 

 hot water boiler is at the north end 

 and stands on the ground level, not in 

 a pit. We have one 4-inch flow and

four 4-inch returns in each house. The 

 flow runs uphill from the boiler, and 

 thus the highest point is farthest from 

 the boiler. We do not get a good cir- 

 culation. What can we do to improve 

 it? Any information that you can 

 give us will be gratefully received.
