Greenhouse Heating. 



As the days begin to lengthen the cold 

 begins to strengthen. How about the coal 

 bins? Are they full? 



A QUEEY FROM NEW ZEALAND. 



I am in business in Christehurch, 

 New Zealand, where the climate and 

 other conditions are unlike those in the 

 United States, and where some of the 

 terms used in the trade are different 

 from the American forms of expression. 



I have read in The Review that the 

 flow pipe, in hot water heating, should 

 rise at once to the highest point of 

 the system and then gradually fall to 

 the return pipes. Does this apply to 

 warmer climates than yours generally 

 is! Is what you call zero 32 degrees 

 Fahrenheit, the same as we use, or is 

 it simply another term for freezing? 

 The degrees below zero mentioned in 

 your paper seem extremely low to me, 

 where about 15 degrees of frost are 

 the record cold weather. I have all 

 my pipes under side benches, rising 

 to the far end, the boiler pit being six 

 feet deep and at one end of the range. 

 As we have practically no snow to 

 melt, would there be any advantage 

 in raising the flow pipes to the eaves, 

 as you sometimes recommend? I grow 

 a general run of stock for retail and 

 wholesale trade — not one particular 

 line. J- H. R. 



The temperature referred to as 

 "zero" is in the Fahrenheit scale 32 

 degrees below the freezing point. It 

 is not uncommon to have the mercury 

 drop to that point during the winter 

 in the northern half of the United 

 States. In some sections, indeed, it 

 occasionally goes down to 10 to 15 

 degrees and even 30 to 40 degrees be- 

 low zero. 



The effect of running the flow pipes 

 overhead is to hasten the circulation, 

 and if they run "downhill" it is still 

 more improved. These points are of 

 less importance when the boiler is be- 

 low the level of the returns and when 

 large pipes are used. 



FIFINQ FOB A SIDE BENCH. 



I should like to get a little informa- 

 tion in regard to my benches. How 

 high should the raised benches be when 

 next to the wall? In my greenhouse, 

 one of the benches is level with the 

 cast-iron plate and only three inches 

 from the wall, and in cold weather it 

 is too cold for the plants next to the

glass. The bench is made of cement. 

 The house is steam heated, with two 

 mains overhead and returns under the 

 benches. Do you think it will be safe 

 to add one return along the glass, and 

 resting on the cast-iron plate? The 

 house will be for roses and carnations 

 and is divided in two. C L. 



It is desirable to have the beds two 

 feet lower than the plate for carnations 

 and even lower than this for roses. 

 There should be a space between the 

 wall and the bench. The placing of 

 an extra return will aid materially in 

 keeping out frost, and if the bench is 

 dropped one and one-half feet or more 

 it will do no harm. 



TWO KANSAS HOUSES. 



Will you please tell me how to pipe 

 my new house with 2-inch pipe for hot 

 water! The house is 11x75 feet, eight 

 feet to the ridge and five feet to the 

 plates, with two feet of glass in the

south side and the ends boarded up 

 tnree feet. I want it piped for 50 

 degrees in zero weather. 



This new house is on the south side 

 of my other house, which is piped with 

 sixteen l^^-inch returns, eight on each 

 side. There are two cast-iron mani- 

 folds on each side, and each coil of 

 eight pipes is fed by one 2-inch flow 

 pipe. Could I replace them with one 

 4-inch flow pipe under the north ben<^, 

 letting the water flow through the mani- 

 fold under the south bench, through 

 the partition into the small house, and 

 return through the partition at the 

 east end of the house in a 2%-inch 

 manifold under the south bench of the 

 large house, and then into the boiler?
