A CLOSED SYSTEM. 



We are lu'atiiig with hot water in a 

 dosed system whieh is operated under 

 fifty pounds pressure. Tlie pipes are on 

 the down-hill plan from the boiler. Will 

 it increase the efficiency to have the 

 flows rise to the farthest point from the 

 boiler? M. A. B. 



Under as high a pressure as you main- 

 tain I doubt if it would prove a very 

 decided advantage to change the slope 

 of the flow pipes in your system. Were 

 you working under a low pressure, six 

 to ten pounds, the change would un- 

 doubtedly result in greater benefit than 

 it would under present conditions. Some 

 slight advantage would result from the 

 change, even with the high pressure you 

 use, but whether or not it would justify 

 the expense of the necessary alterations 

 is difficult to predict. L. C. C. 



HEATING IN OREGON. 



We have a shop 18x18 under which is 

 a basement. Running south from the 

 shop is an even-span house 18x.52 and 

 ten and one-half feet to the ridge. Run- 

 ning west from the shop is a three- 

 quarter-span house 18x7;"5 and eight feet 

 to the ridge. We want to heat these 

 two houses witli one furnace, using a 

 pipe boiler and hot water under ten to 

 fifteen pounds of pressure. Will you 

 jdease advise us as to size of boiler, 

 amount of piping, etc. We already have 

 a brick chimney 12x16 inches inside 

 measure and eighteen feet high. The 

 tenii)erature at night must be 55 degrees 

 in the longer house and 50 in the shorter 

 liouse. The thermonieter rarely falls be- 

 low zero here. H. & F. 



The two houses which you wish to 

 heat will require pij)e as follows, if the 

 sizes I have selected are satisfactory: 

 The house fifty-two feet long can be 

 successfully heated with a 2-inch flow 

 and nine I'-inch returns arranged under 

 the benches or along the side walls. The 

 house seventy-five feet long, if supplied 

 with a 2i/^.-inch riser and thirteen 2-incli 

 returns, arranged aa above suggested for 

 the smaller house, will give the tempera- 

 ture desired. 



If you use a pipe boiler as you sug- 

 gest it should have a heating capacity 

 to carry about 1,20() feet of radiation. 

 To accomplish this the l>oiler should 

 have at least 150 feet of heating sur- 

 face. If li/L'-incli pipe i^ used for the

construction of the boiler the coils 

 should be made to contain between .300 

 and H25 lineal feet of pipe of that size. 

 The number of pipes in the manifolds 

 used will depend upon the length. A 

 boiler containing less than 300 feet of 

 li/j-iiifh pipe, exposed to the fire will not 

 have sufficient capacity to do your work.

 tion of such a boiler see Florists ' Re-

LEAKY GUTTERS. 



1 have in Knoxville a number of con- 

 necting iiouses which were built a year 

 ajiart which caused us to use single gut- 

 ters, which, of course, made it <lifficult 

 to prevent them from leaking. I wish to 

 fill the openings through which the water 

 pours in the smallest rains and I do not 

 know what is best to use for that i)ur- 

 pose. (an you give me information 

 which will be the safest? H. L. L. 



We are not certain that we fully un- 

 derstand the trouble. We take it that

where one house has been attached to 

 another, there is an imperfect gutter 

 and there arc some open joints that 

 leak. If this is the case, then thoroughly 

 clean the gutters and wherever there is 

 an opening, say of a .sixteenth of an inch, 

 plug it full of a mixture of white and 

 red lead, which should be about the con- 

 sistency of putty. The red lead you buy 

 as a dry powder and that will stiffen up 

 the white lead. Then give the whole 

 surface of the gutter two coats of thick 

 white lead paint. That should prevent 

 any leaking. Our 2-in<*h cypress gutters 

 we ])aint annually and'liave no trouble 

 with them. " W. S. 



INSUFnaENT DETAIL. 



We have a greenliouse heatetl by a 

 Wilks boiler. The house rises about 

 eight feet in its length of 100 feet. The 

 main flow runs on a gradual rise to the 

 highest point of the house. Another 

 flow rises four feet at the boiler, then 

 has a gradual rise of ten feet, drops six 

 feet and returns to the boiler gradually. 

 The boiler has about as much 2-inch
