Thermal efficiency reaches up to 109%, delivering up to 30% energy savings compared with conventional wall‑hung boilers. It greatly cuts gas expenditure over long‑term use. For buildings with large heating areas, users can even save enough gas cost to cover the price of the unit within 2‑3 years. NOₓ emission is far lower than that of ordinary boilers.
2.Stable Domestic Hot Water
Adopting staged combustion technology and three‑point temperature control, the fully premixed boiler supplies hot water in 17 seconds. It achieves precise temperature control without water‑temperature fluctuation. Combined with variable‑frequency staged combustion and proportional premix adjustment, it supports extremely low minimum output power.
3.Patented Air Filtration System
Our exclusive patented air filtration system reduces expensive maintenance costs for users. Unique on the market, it allows self‑disassembly without on‑site cleaning service from agents. It effectively prevents heat‑exchanger blockage caused by poor‑quality ambient air.
4.Imported Core Components with Proven Reliability
Heat exchangers and burners are imported from Italy, equipped with SIT proportional valves. Since we began manufacturing fully premixed wall‑hung boilers in 2016, these key components have achieved a zero‑failure record.
5.User‑Friendly Operation for All Ages
Full‑glass touch panel, large digital display and intuitive icons make it easy for the elderly and children to operate.
6.Time‑Scheduled Zonal Heating
Users can set custom temperatures for different time periods according to daily routines. Low‑temperature standby mode can be activated when no‑one is at home to avoid unnecessary energy waste.
7.Mobile Remote Control
Adjust temperature, monitor operating status and switch the boiler on/off anytime and anywhere via smartphone.
8.Ultra‑Low‑Noise Operation
Variable‑frequency combustion technology plus 360‑degree sound‑insulated cabinet ensures quiet operation; running noise is barely perceptible.
9.Optimized for Low‑Temperature Underfloor Heating for Maximum Energy‑Saving
The optimal supply‑water temperature for underfloor heating is 40‑55 °C. Low return‑water temperature facilitates waste‑heat recovery via condensation. It also works for high‑temperature radiator systems, though energy‑saving performance is less prominent. Condensing boilers are the top choice for underfloor heating projects.
