Ir subscribers will state clearly the de- 

 tails of their heating problems, the Re- 

 view will give in this column the opinion 

 of a man thoroughly familiar with the 

 practical side of greenhouse heating. 



HOW ABOUT COAL? 



Is your coal bin full? 



If it isn 't, it ought to be filled without 

 delay. The coal market has been in favor 

 of the buyer all summer and as the trade 

 becomes more and more forehanded each 

 year, the sheds are being filled earlier 

 and earlier, in order to take advantage of 

 the low prices that usually are to be had 

 during the dull season in the coal busi- 

 ness. Fuel never is cheaper in autumn 

 than it is in early summer. This year 

 there has been little, if any, advance in 

 prices as the summer has progressed, but 

 there is already a better feeling in the 

 coal trade as a result of some improve- 

 ment in the demand. Those who haven't 

 bought ought to do so at once, and fill 

 the sheds. 



Unfortunately, there still are some cut 

 flower growers who pay too much at- 

 tention to the fuel bill — who, by their 

 efforts to keep down the consumption of 

 coal, knock themselves out of a dollar 

 for every dime they save on fuel. Rose 

 growers especially suffer as a result of 

 this false economy, losing far more 

 through mildew than it would cost to 

 keep the fires going all summer, so that 

 steam could be turned into the pipes a 

 little while every cool night. 



HEAT FOR SMALL HOUSE. 



I have a greenhouse 18x26 feet, four 

 feet high to the plates and nine feet to 

 the ridge. I am going to heat with hot 

 water. I want to heat to 45 degrees now 

 and later use it for a carnation house. 

 How many feet of 2-inch pipe will I need 

 to heat to 45 degrees, and how many for 

 50 degrees? It gets as cold as 20 de- 

 grees below zero here. I want to pipe 

 under the benches, the water going down 

 one side and back on the other.

 pipe, letting them be divided four on

.each side of the house, feeding the right- 

 hand set and gathering the left-hand 

 pipes into a return. This will take about 

 225 feet of pipe. G. T. E. 



OLD BOILER TUBES. 



On page 69 of the issue dated August 

 26, 1909, under the head "Old Boiler 

 Tubes," a party asks for information 

 "as to how many 4-inch pipes we need 

 to heat a house 26x118 in northern Illinois 

 climate. We want to heat to 60 degrees 

 at 10 degrees below zero. ' ' 



The one answering this inquiry makes 

 a statement which is very misleading 

 when he says : * ' Heating experts do not 

 recommend the use of 4-inch pipe in 

 houses over 100 feet in length unless the 

 boiler shed is at the middle of the house, 

 so the runs of the pipe will be less than 

 100 feet long." In this connection I 

 would say that the Lord & Burnham Co. 

 often pipes greenhouses 200 feet long 

 with 4-inch external diameter cast-iron 

 pipe, and 2-inch wrought-iron pipe where 

 the boiler is placed at the end of the 

 house, and we find same to be satisfac- 

 tory in every way. 



It also is stated that "eight 4-inch 

 pipes the length of the house should sup- 

 ply the desired temperature with a boiler 

 temperature of 180 degrees and normal 

 circulation." We find, on figuring this 

 out, that it will require 1,490 lineal feet 

 of 4-inch tubes to give the desired tem- 

 perature, viz., 60 degrees at 10 degrees 

 below zero. Since the house is running 

 north and south, we would advise placing

four lines under each of the two outside 

 benches, two flows and two returns, and 

 two lines under each center bench, to- 

 gether with about seventy feet at the 

 south gable. If this amount of radiation 

 is properly placed and the heating ap- 

 paratus installed with suitable mains, 

 with a boiler of ample capacity, the re- 

 quired temperature would be maintained 

 without any trouble. Geo. W. Sykes. 



A SICK SYSTEM. 



My heating system has grown as I 

 have added to my glass and is not uni- 

 form; I have to confess it does not work 

 as well as I could wish, but it is not 

 possible to change this season. Some 

 of the feed pipes are downhill and 

 some arc uphill; they work, all right, 

 but might do better if they were all on 

 the same grade. I have raised the ex-
