fireenhoose Heating. 



Greenhouse heating experts agree 

 there is no better investment, in the av- 

 erage ease, than a good, big, deep boiler 

 pit; especially deep. 



If your heating apparatus does not 

 work as it should, describe it as mi- 

 nutely as possible and the Eeview will 

 give you, in this column, the benefit of 

 the advice of a practical heating engineer. 



Those growers who did not stock up 

 with fuel— and not all are forehanded — 

 are finding some irregularity in the ship- 

 ment of their fuel supply, for the coal 

 business has enjoyed a boom in the last 

 few weeks that has disturbed arrange- 

 ments. Car shortage is one of the diffi- 

 culties tlie shippers have to contend with 

 and in the opinion of well informed job- 

 bers the trouble will last another thirty 

 days at least. Don't let your coal bins 

 get too low before you -order. 



HOUSE FOR MUiHROOMS. 



Will one run of ll-^-'uu-h pipe, placed 

 at both sides and at the ends, be enough 

 for a mushroom house 12x40, and six 

 feet four inches high, in northwestern 

 Pennsylvania? Will the expansion tank 

 work satisfactorily if placed right above 

 the boiler, and will an 8-gallon tank be 

 large enough? Our heater has a l^^l.-inch 

 opening for the flow. T. J. 



Such a building will require at least a 

 2-inch flow, but this can be fed from the 

 l^,o-inch opening in the boiler by using 

 a filling to reduce the 2-inch pipe to l\<i 

 inch, using only a close nipple in the 

 l)oiler. You should have a 50-gallon ex- 

 pansion tank, connected with the main 

 return close to the boiler by a small 

 pipe, say ''}i-'md\, and the tank should be 

 elevated eight or ten feet above the 

 highest point in the system. C. 



HEATING PROPAGATING HOUSE. 



What is the best and cheapest way to 

 heat a greenhouse about 15x20, which I 

 have put up beside my dwelling? It is 

 intended principally for geranium cut- 

 tings. I have no other greenhouses near 

 it. I have a potting shed attached to 

 (1)10 end, and, though I never heard of its

being done, I thought of trying to heat 

 it with a stove in the shed, or in the 

 dwelling house itself. Would this work? 

 What Avould you suggest? I am located 

 in a pretty cold climate. B. A. K. 



I doubt if you will be able to maintain 

 a satisfactory temperature in your propa- 

 gating house by using a stove. A small 

 hot Avater heating plant would, it seems 

 to me, be preferable to anything else 

 for such a place. If the greenhouse is a 

 lean-to attached to the dwelling, the 

 heater might be located in the cellar of 

 the house. It is often a greater problem 

 to heat economically a small plant of 

 this character than a large one. C. 



A KENTUCKY HOUSE. 



I have my house ready for the pipes 

 and should like your opinion. The house 

 runs east and west and is 17^/^x100 feet, 

 eleven feet four inches to the ridge and 

 four and a half feet high at the sides, 

 with eighteen inches of glass in the soutli 

 side. I am thinking of putting in one 

 2-inch flow and five 2-inch returns on 

 each side, as I have solid beds. Or 

 would it be better to put in one 3-ineh 

 flow under tire ridge and five 2-inch re- 

 turns on each side? With the expansion 

 tank on the roof of the shed, over the 

 boiler, I believe I would get more pres- 

 sure by the first method. I intend to 

 have a closed expansion tank. Can I 

 connect it with the return near the 

 boiler, or what is the best way? I want 

 to get all tne pressure I can. Please ex-

plain how to put up a closed tank anil 

 how to use it without any danger. I can gi'i 

 1^4 -inch pipes much, cheaper. Would yo.i

If you cannot put the top of the boiler 

 below the level of the returns on the 

 sides, then you will get best results by 

 using the single overhead flow — the 3-incli 

 flow. The only way to increase the pre? 

 sure in your system is by elevating fn' 

 expansion tank. Connect the tank ■with 

 the main return close to the boiler anil 

 place the tank twelve or fifteen feet abovr 

 the highest pipe in the house. This
