The AquaHeater Smart is a product that is designed to fullfill the client needs on the area of energy consumption reduction. Not only is it an highly efficient module for energy savings, also savings in the area of shortening processes can be realized with the AquaHeater Smart. If the temperature in the warm water tank is lower than the set point on the Aquaheater display, the heater unit is engaged. The boiler is directly fired offering maximum efficiency. This particular performance is achieved partly through the use of a special stainless steel heat exchanger. The heat exchanger enables the cooling of exhaust gases below the condensation point, which releases additional heat. This has an immediate positive effect on efficiency, which exceeds 100% This concept permits installation at point of use, avoiding costs in - boiler investment & usage, - steam and condensate piping, - condensate traps and regular inspections - energy loss during transport - as well as a higher energy to water temp. conversion
