Introduction

Atmospheric pressure hot water boilers are also called pressureless hot water boilers, which belong to the category of domestic boilers. It is a non-pressure hot water boiler with an air vent on the top and the boiler body is always operating at normal pressure. The main feature of the normal pressure hot water boiler is that the boiler is not pressure-bearing and has no safety hazards. It is mainly used for heating and producing hot water. It is one of our more common types of boilers.

Advantages

Multi-return heat exchange, multi-fin design, ultra-large heat exchange area, and thermal efficiency of over 92%.
The combustion chamber design can easily match different types of burners, including low NOx emission burners.
The burner door with insulating ceramic material is equipped with a reversible hinge, and the smoke pipe can be easily accessed after opening for easy maintenance.
The furnace, furnace door, insulation, packaging, control and other parts of the boiler follow overall subassembly, module combination, and no blind spot maintenance.
