Description
EKO MAX boilers are eco-pea boilers designed for heating large-area surfaces. The Eko Max boiler was built from high-quality certified steel sheets. It consists of two parts: the combustion chamber, where all fuel combustion processes take place supplied by the feeding system with air participation, and the convection part, which constitutes a two-pass horizontal flame tube heat exchanger, which transitions into a chimney connection at the rear of the boiler. The combustion chamber doors are equipped with a sight glass, allowing us to monitor the flame condition in the combustion chamber. To reduce heat loss, the external part of the boiler is insulated with steel sheet cladding, under which thermal insulation is placed. The furnace also has an electronic controller that monitors the temperature level in the boiler and adjusts it accordingly. It also controls the operation of the heating and domestic hot water pumps.
Standard equipment:
- heating, domestic hot water and 1 additional pump,
- GSM Module,
- weekly operation,
- PID program,
- Ethernet Module,
Optional equipment:
- additional solenoid valve module control,
- room controller with RS communication,
- room controller
Standard equipment:
4 years warranty on heat exchanger tightness, 2 years on other components and proper boiler operation;
heat exchanger made from certified boiler steel
Designed for heating large-area buildings
