THE USERS OF THE 



Hu^fhson Regulating Valve 



are all satisfied with the results it has given, 

 and many duplicate orders is the proof. 



This Valve Will Maintain a Steady Pressure

 had better get one— it is yours for the asking.

 By carrying 40 or 50 pounds pressure on the boiler and setting 

 the valve to cany 5 or 10 pounds on the line, you always 

 have a reserve to fall

way to put it in! The boiler is a tubu- 

 lar hot water boiler, nine feet long, 

 fifty-two inches high and forty-two 

 inches wide. 



I have let the heating job to a local 

 plumber and he will furnish everything, 

 leaving the job complete, but I think 

 he is using too many pipes. These are 

 his figures: One 6-inch tap from the 

 boiler, about ten or twelve feet long; 

 one 4-inch overhead flow in each house; 

 four 2-inch returns under three benches 

 and three 2-inch returns under one 

 bench in each house. J. L. M. 



For the carnation house one 4-inch 

 flow and twelve 2-inch returns should 

 be suflScient to maintain a temperature 

 of 50 to 55 degrees, but it would be 

 better to substitute two 2^-inch flow 

 pipes for the single 4-inch flow, though 

 the latter is, of course, large enough 

 to supply the returns. In the rose 

 house use three 2%,-inch flow pipes and 

 fourteen 2-inch returns. If the 4-inch 

 main is to be used, sixteen returns 

 would be needed. The above radiation 

 is considerably larger than would be 

 needed unless the thermometer is lower 

 than 15 degrees below zero, with high 

 winds. 



A HOUSE FOR QENEKAI. STOCK. 



1 am building a Lord & Burnham 

 house, 28x50 feet, for general stock. 

 Please tell me the amount- of piping 

 required and how to locate it to best 

 advantage. In this part of Maine the 

 outside temperature occasionally drops 

 to 20 degrees below zero for several 

 days at a time. I am planning to use 

 one bench for chrysanthemums, to be 

 followed by geraniums and bedding 



The 'ideaF' Hot Water Circulator 



THE ''IDEAL" is the Original Automatic circulator, and 

 is the simplest and most efficient circulator on the market.

Sectional Cut of Improved Circulator No. 0. . '^ 



~ Some Advantages of tiie ''ideal** Circulator 



(1) Improves to perfection the circulation In hot water plants that are de- 

 fective. 



(2) Enables present hot water systems to be extended to a very large extent 

 without increasing the size of the pipes or the height of the circulating head. 



(3) Owing to the reduced size of the main piping required, it considerably 

 reduces the flrst cost of installation. 



(4) Gives an even temperature in the pipes throughout the system. 

 Reduces the amount of radiating pipes required. 

 Enables smaller piping to be used. 



Piping may be placed below boiler level as well as above. «-4a 



Effects a large economy in cost of fuel. y - 'f >• 



Requires a very small amount of power to operate (1-10 of one horSe 



power being sufficient for 5,000 sq. ft. of heating surface). 



(10) Can be used as an auxiliary to gravity system, and does not Impede the 

 flow of water at times when forced circulation is not required, as its action is perfectly 

 automatic.
