Greenhouse Heating. 



Don't let the boiler stand empty all 

 summer. "When you are through firing 

 draw off the water and fill the system 

 full of fresh water. 



Makeshift heating apparatus is about 

 the most expensive thing a greenhouse 

 owner can invest in. A well planned, 

 well installed system may cost something, 

 but it is an investment that pays large 

 dividends through fuel saved and also 

 through the improved quality of the out- 

 put of the houses. 



SUBSCEIBERS 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. 



ACCELERATING CIRCULATION. 



We would appreciate information on 

 hot water circulation. The circulation 

 in our heating coils is too slow. We 

 have a^ open system. Would a change 

 to a closed system be the best remedy? 

 The expansion tank is about six feet 

 above the boiler. When we run a good 

 fire it makes steam, stops the circula- 

 tion and forces the water through the 

 expansion tank. How would we have 

 to arrange the piping for a closed sys- 

 tem? There is a vent pipe on the far- 

 ther end of each pipe. F. & K. 



In such a case, before putting in a 

 closed system, it is well to make needed 

 changes in the present piping and give 

 it another trial as an open system. I

would sugest running the tlow pipes so 

 that they will have a slight slope from 

 the boiler. Keep these pipes, as well as 

 the returns, as high as possible. Con- 

 nect the expansion tank with the high- 

 est 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. F. E. 



THE FUEL MARKET. 



The coal trade, though still dull, is 

 beginning to sit up and take notice 

 again. Following the flurry that came 

 at the time of the suspension of min- 

 ing, April 1, the market relapsed into 

 an interval of suspended animation, 

 from which it is only now emerging. 

 The large consumers, and the number 

 included all the larger greenhouse es- 

 tablishments, laid in a reserve stock 

 when it was seen that a shutdown of 

 the mines was about to occur, and 

 when the labor difficulties proved to be 

 of short duration they stopped buying 



while they used up the reserve supply. 

 Now that more than sixty days have 

 passed, the reserve supplies are about 

 down to normal and most of the larger 

 buyers are feeling the market again. 

 They find it pretty well settled down to 

 normal conditions, demand perhaps not 

 yet quite up to the usual firat-part-of- 

 June level in spite of the late spring, 

 but prices a few cents a ton above 

 what they usually are at this date, be- 

 cause of the recent advance in miners' 

 wages. 



The coal trade has noticed that the 

 greenhouse trade, as it is known to the 

 fuel people, is year by year becoming 

 less inclined to enter into contracts for 

 the season's supply. Time was when 

 practically all the important greenhouse 

 concerns placed orders for the year's 

 supply, that part which represented the 

 capacity of the sheds to be delivered 

 during the summer and the balance at 

 the rate of a stated number of cars per 

 week during the winter. In certain 

 cases this has worked so satisfactorily 

 that in many years the florists have 

 seen no reason to change the method,

 the air spaces open as long as possible under all conditions.
