FAQ

The shipping time depends on the boiler model, because some of our boiler has stock, some boiler will be customized according to customer's requirement, so the final shipping time is different. While generally, shipping time is 15-30days if need to be customized.

For users who require gas boilers to be in operation for a long time every day, it is more sensible to choose a condensing gas boiler. The condenser is used to recover the waste heat in the flue gas discharged from the tail of the boiler to increase the boiler inlet water temperature and make the boiler thermal efficiency as high as 98 %above. In the case of the same amount of gas, the more heat recovered by the condenser means that the utilization rate of fuel will be further improved, which will save users a large amount of fuel costs each year, and the effect of energy saving and environmental protection is very significant. At present, condensing gas boilers have been widely used in industrial production by virtue of their own performance advantages, and occupy a place in the market.

The common steam pressure is 0.4Mpa, 0.7Mpa, 1.25Mpa, 1.6Mpa. Excepting above common pressure, customized steam pressure is available. During our projects, we have done steam boiler for 2.0Mpa, 2.5Mpa, etc.

Heating area is one parameter of boiler, which refers to the inner furnace heating area and it is related to boiler volume. The bigger of the heating area of boiler, the boiler volume is bigger.

All our boiler departures from factory, we will do series safety test for the boiler, for example, water pressure test, weld tightness test, etc., in order to keep boiler reliable and safety.

As we add coil tube on top of thermal oil boiler, the thermal efficiency can up to 92.26%, higher more than two points than common oil/gas fired thermal oil boiler, which is our patent technology.

 Boiler delivery depends on the term we confirmed in the contract, for FOB term, we will be in charge of delivering our boiler to ship, while for CIF term, we will in charge of delivering our boiler to discharge port.

When boiler departures our factory, all set of boiler operating manual is attached, and if the operating manual can not help you, our email, telephone, whatsapp and skype are available for you at any time, and our engineer is available to go your country for the technical support.
