The ARDENT commercial electric boiler range, encompassing wall-hung and floor-standing variants with heat outputs from 9 to 100 kW, provides an easy-to-integrate, high capacity, reliable, and compact response for electric hot water and central heating demands in commercial buildings.
ARDENT is designed to serve as an indirect water heater or heating system. Multiple electric heating elements immersed into ARDENT’s integrated water storage tank provide a rapid and reliable source of thermal energy for those seeking to avoid a reliance on gas energy supplies.

For larger-scale applications, ARDENT is also available as a floor-standing appliance with 60 kW, 80 kW and 100 kW heat outputs.
Stepped element control is included, as well as an automatic air relief valve, safety valve, and temperature and pressure sensors. The integral controller boasts an LCD display and fault output.
Foor-standing ARDENT appliances offer rear flanged pipework connections and boast a protective IP20-rated outer shell.
Additional Information
ARDENT perfectly integrates with a heat pump to provide an additional high-temperature energy source for water heating during the coldest months.
Or, as part of an indirect hot water system, can help eliminate scale build-up common on direct electrical immersion heaters
The Adveco ARDENT brochure provides you with a quick and easy reference guide to this range of compact and highly efficient, wall-mounted and floor-standing electric boilers.
