Wall-mounted natural gas or condensing gas boilers Performance **** according to the European Directive EEC 92/42, ensuring low operating costs.
- Low emissions.
- Condensation exchanger made of aluminum alloy, with premix burner.
- Combined operation. The Residence Externa Condens wall-mounted boiler is specially designed for outdoor installation. All boiler functions are controlled remotely using the REC 08 remote control panel. Its innovative primary exchanger is made entirely of aluminum alloy and front access to the combustion chamber ensures better performance and longer life. Residence Externa Condens is available in 20 and 30 kW.
- REC 08 remote control panel (available in the package).
- High configuration ratio of 1:8 which allows the boiler to respond to any heat demand.
- “Range Rated” certification: ensures maximum performance throughout its power range and can be easily adjusted to the actual needs of the system.
- High efficiency pump with low energy consumption (IEE ≤ 0.20) and self-adjusting analog operation.
- Antifreeze function which protects the heating and DHW circuits up to -5°C, with the possibility of extending the protection up to -15°C (optional).
- "Winter with preheating" function: maintains the temperature in the DHW exchanger, thus reducing the waiting time from the moment of demand.
- Possibility of installation in a non-roofed location with the use of a suitable kit (optional).
- Built-in compensation software using an external sensor environment (as accessories).
- The boiler is equipped with a mounting pattern, hydraulic adjustment, a gas and domestic water valve.
