Oil-fired hot water boiler is a type of boiler that can output high-temperature hot water. In terms of pressure division, there are normal pressure, negative pressure and pressure. Generally speaking, if it is heating and heating, it is enough to use atmospheric pressure oil-fired hot water boiler, which can not only reach the required temperature, but also ensure safety.
Atmospheric pressure oil-fired hot water boiler adopts atmospheric design in the structural design, and the top of the boiler is provided with an atmospheric hole. The internal pressure is always balanced with the external pressure, so that the danger of explosion can be avoided.
In addition, the furnace body of the boiler adopts computer optimization simulation design in order to optimize its size, get a good appearance and shape, and also save a lot of floor space.
The use of glass wool in the oil-fired hot water boiler is used for the whole-body insulation, which has better insulation effect. The advantages of glass wool are light weight and small heat loss, so its thermal insulation effect is very good.
The main components of the atmospheric fuel oil hot water boiler are the fuel oil burner, the boiler controller and the hot water circulation pump, which are very important and indispensable.
The scope of application of the fuel gas vacuum hot water boiler in the fuel oil hot water boiler is generally on the heat source of heating load, ventilation and air conditioning heat load. Especially, when it needs to be installed in a building, it is very suitable to use this kind of boiler, and it also has good use effect.






We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
