Ten days ago I was called to t'leve-

 tiire was 4f) dcgnM's at 2:40 ji. m., when 

 I left tiie boiler, with a gradually sink- 

 ing mercury. There being no men about, 

 1 left instructions that the boiler should 

 not be touchcil until next im)rning. My 

 wife, on my return next evening, re- 

 ported that at 7 p. ni. it liccame (juite 

 windy and by ^J:'M) was freezing, with 

 stormy outlook. When she awoke at G 

 a. m. the outside teni]ierature \\;\s 2G 

 degrees and tlie greenhouses were 47 de- 

 grees. I think this is a record for tif- 

 tecn hours and twenty minutes without 

 attcmtion. I would like to hear from 

 anyone who ran beat it.

VENT PIPE FREEZING. 



1 have been having trouble with my 

 vent ])ilie freezing up a time or two, and 

 wish to know how to overcome it. I have 

 a Jio-iiich flow jiijio with the vent on the 

 liighest ]>oint. The vent is 1-inch pipe 

 and extends thrcnigh the roof, but I have 

 it boxed aroutni so it looks as if it should 

 not fret>ze. S. E. L. 



I know of no better way of insuring 

 tlie vent pijte in fjuestion against freezing 

 than to cover it with an asbestos jacket. 

 Such jiijie covering can be purchased 

 ready prepared for any size of pipe. This 

 would only require adjusting to the 

 jiipe. My j)lan of meeting this dilhculty 

 would be to dispense with the vetit ]"ipe 

 altogether, place an airvalve in the sys- 

 tem at this point ami connect an expan- 

 sion tank to the main return near the 

 boiler and elevate this several feet, ten 

 or more, above the highest point in the 

 system. This will give you a pressure 

 system which will provide a quicker cir- 

 culation and a greater heat, thus mak- 

 ing the svstem more efficient.

ELEVATE EXPANSION TANK. 



I have a No. 3 Kro<'schell hot water 

 boiler with overhead Hows and under 

 bench returns, the highest ])oint being 

 farthest from the boiler, and an open 

 tank. How high can 1 place tiie expan- 

 sion tank above the highest point? The 

 boiler is just the ordinary kind, m)t 

 built for high jiressure. The pipe from 

 the ex](a]ision tank to the main return

The boiler you have will easily .stand 

 fifteen or twenty j)Oiinds ])rcssure. In 

 order to make lifteen pounds ])ressnro on 

 the boiler it wonld be necessary to have 

 the exjiansion tank raised thirty-three 

 feet. This is probably not practicable, 

 bnt you can undoubtedly elevate it ten 

 or twelve feet hifjher without ^reat in- 

 convenience or expense. This will help 

 to maintain a considerably higher heat 

 on the system. While I do not think 

 the point at which the expansion tank 

 pipe is taken oil' the ideal one, yet I

do not know that it would be enough 

 better in the ideal place to ju.stify the 

 change. The ideal jilace is on the main 

 return within eight or ten inches of the 

 boiler. The size of the pipe is greater 

 than is necessary. A ','4 -inch pipe would 

 be large enough, although the greater 

 size is no disadvantage. The incline in 

 the pipe m.'ikes no difference. The per- 

 pendicular height is the all-important 

 point and it makes no diff'erence whether 

 the tank is directly over the boiler or at 

 one side as vou have it. Ij. C. C.
