TO MAINTAIN AN EVEN TEMPERATURE 

 in your greenhouses, use a 



Foster Pr^sure Regulator 



With this simple device attached to your steam 

 main just inside the greenhouse the pressure on 

 the heating coils will be absolutely constant, any- 

 where from 1 to 15 pounds (whatever the grower 



sets the Regulator at), no m^ter how the pressure on the boilers 



runs up and down. s ^^^^' 



If the weather changes, or the sun heat varies, instead of turning on more pipes, just 



turn a nut on the Regulator, and get nxo^e steam, or less steam, at once. Made in sizes 



from ^-inch to 10-inch just for this work. 



"The Foster Pressure Regnlators which have been installed in our greenhouses are giving 

 perfect satisfaction." — Peter Reinberq, Chicago. 



As an expert in your line, let us talk it over, as experts in ours. We

The 'ideaF' Hot Water Circulator 



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

 is the simplest and most eflfident circulator on the market. 



Sectional Cut of improved Circulator No. 6 



Some Advantages of tlie ''IdeaP* Circulator 



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



(2) Ehiables 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 first 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. 

 Effects a large economy in cost of fuel. 



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

 power being sufficient for 5,000 so. 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. _. , ^,.
