Main selling points

1.Reliable and safe: operates in a vacuum negative pressure environment with extremely low risk of explosion

2.Dual environmental protection, low nitrogen combustion NOx emissions<30mg/m ³

3.Condensation technology, energy-saving and efficient, recovers latent heat of flue gas, with a thermal efficiency of up to 102% -107%. Phase change heat transfer, ordinary boilers save 15% -25% gas.

4.One machine can be used for multiple purposes, and one boiler can be equipped with multiple sets of heat exchangers

Main fuel

First choice: natural gas (pipeline gas).
Alternative: Liquefied petroleum gas. Very little use of fuel.
Core: Its efficient combustion and condensation technology is optimized for clean gaseous fuels.

Economic Summary

The purchase price of a single device is about 20% -40% higher than that of a regular gas-fired hot water boiler, but

Higher gas savings
Zeroing regulation and labor costs
Relatively low maintenance costs

Economic efficiency analysis

cost item	make a concrete analysis
Initial investment	The equipment price is relatively high. But the system investment may be lower
Operating cost	Thermal efficiency>100%, gas cost savings of 15% -25%
Maintenance cost	No scaling, low corrosion
Risk cost	The absolute pressure inside the vacuum hot water unit during operation is 0.02~0.065MPa, so there will be no explosion.
