Dear Mr. Komornicki:

Ludell appreciates your continued interest in our Energy Conservation Equipment. This
correspondence is sent in response to your request for an equipment proposal regarding our Hi-

boiler for producing hot water when steam is not needed. Benefits of the water heater include:

 Highly Energy Efficient.
 Low Capital Investment.
 East of Installation.
 Simple to Operate.
 Non-Pressurized Vessel; no special operating permits or certified boiler inspections.
 No Boiler Tubes to Rod-Out, or Maintain.
 Hot Water is available instantaneously, no waiting for hot water.
 Stainless Steel Construction, for equipment long life.
 Return on Investment due to heater’s high efficiency.
 Save typically 30% on water heating fuel bill, over a conventional water heating system.

Ludell has provided energy conservation equipment to a variety of industries for over 60 years,
and we are pleased to propose an energy efficient hot water system for your client’s concrete
facility. This correspondence includes an equipment proposal that is capable of heating 5,760*
gallons per hour of water continuously from 55 F. to 170 F. * Note: 5,760 gallons per hour is
