Frequently Asked Questions
How do I choose the right power for my home?
For 80-150m², 24KW is ideal for heating and hot water. For villas over 150m², choose 28KW or above. In colder regions or homes with multiple bathrooms, consider increasing power by 20-30%.
Can it provide heating and hot water at the same time?
The system prioritizes hot water. Heating will temporarily pause when the hot water faucet is opened and resume automatically once the faucet is closed.
Is the energy efficiency rating significant?
Yes, first-class efficiency units (condensing boilers) can reach over 107% thermal efficiency, saving 15-20% on gas costs compared to ordinary boilers.
Can I install this in an old house without pre-installed pipes?
Yes. You can use an open-air radiator system which doesn't require damaging walls or existing decoration, making it perfect for renovations.
How do I prevent the unit from freezing in winter?
Keep the power and gas on to use the built-in anti-freezing mode. If away for long periods, drain the water from the machine and pipes to prevent damage.
Does the boiler consume a lot of electricity?
No. The main components (fan and pump) only use 100-200W and only run when needed. The monthly consumption is comparable to a standard refrigerator.
