- Water shortage alarm reminds users to refill the heating system water.
- Over-pressure protection releases extra pressure automatically.
- Built-in safety relief valve releases pressure when overloaded.
The boiler is fully compatible with two mainstream heating terminals: underfloor heating and radiators. It can supply low-temperature water for gentle floor heating and high-temperature water for fast-heating radiators. Users can choose the terminal type freely according to house structure and preference. One machine flexibly meets different household heating demands.
Anti-scale protection extends the service life of the heat exchanger in hard water zones. Hard tap water contains calcium and magnesium ions, which precipitate and form scale when heated. Thick scale reduces heat transfer efficiency, increases gas consumption, and can even cause local overheating damage.
This boiler reserves installation space for magnetic or electrolytic anti-scale devices at the cold water inlet. Users can add anti-scale accessories onsite conveniently without modifying the boiler's internal structure. The plate heat exchanger for domestic hot water adopts a special smooth surface coating to reduce scale adhesion. Combined with regular water filter cleaning, this anti-scale system significantly slows scale accumulation. We also recommend local installers add a water softener for extremely hard water areas.
The boiler's control program monitors heat exchanger temperature rise. If abnormal temperature rise caused by heavy scaling is detected, the system will display a warning reminder to inform users to clean the heat exchanger before serious scaling damage occurs.
