Dear Sir:— We are glad to report that the " Compound Vacuum System of Heating" which you installed for 

 us last fall, has given good satisfaction. We find our range, which covers about 3 acres, is equally heated at all 

 points, the action of the Vacuum System being equally good close to and at the greatest distance from boilers — 

 and always positive and reliable. We can heartily recommend your system for the heating of large areas. 



Very truly yours, Dixbar & Hopkins. 



The Proof of the System is in the Heating

Gentlemen:— I will say that your heating system for my greenhouses, as installed by you in vacuum system, 

 has given perfect satisfaction in every way, and I will cheerfully recommend any prospective operator to use the 

 same. Yours very truly, John L. Parker.

 Mr. F. a. Simonds, Manager, Detroit, Mich. 



Dear Sir:— In answer to your inquiry of the 8th inst., will say that the Simonds Vacuum Heating System 

 installed in oiir greenhouses last season is giving perfect satisfaction. As you know, we are using the exhaust steam 

 from the Darling Milling Co., situated 310 feet from our greenhouses. We have no difficulty in heating the houses 

 at any time, in any kind of weather, at atmospheric pressure. Will also say that we saved the price of your system, 

 in being able to cat down our supply pipes alone over the other system. We remain yours, 



Cha.mberlain & Bi nker, per R. L. Chamberlain.
