A: For 80-150m², 24KW is ideal for one kitchen and twin bathrooms. For 150m²+ or villas, choose 28KW or above. In colder regions or homes with multiple bathrooms, consider increasing power by 20-30%.
A: No, it prioritizes hot water. When a faucet is opened, it automatically switches to hot water mode and resumes heating once the faucet is closed.
A: These are typically condensing units with >107% thermal efficiency, saving 15-20% on gas compared to standard boilers, which quickly covers the initial cost difference.
A: Domestic hot water will stop, but the heating system (a closed loop) will continue to operate normally as it does not require real-time water refills.
A: For short trips, use the anti-freezing mode (keep power/gas on). For long absences, turn off utilities and drain all water from the machine and pipes.
A: No. Components like fans and pumps use only 100-200W/h and run intermittently. Total monthly consumption is comparable to a standard refrigerator.
