From the comparisons of central heating of power plant and dispersed heating of domestic natural gas boiler in the field of investment and heating cost, the author gives the judgment for heating methods.

Analysis of common issues in the gas boiler heating system;

The task of gas boiler combustion control system is energy-saving, atmosphere improvement in boiler chamber and reducing pollution.

Discussion on engineering application schemes of heat recovery technology of natural gas boilers

This paper analyzes the market situation and application of the domestic gas boiler, probes into the definition, regulation, management and design of this kind of heating mode, and puts forward the applicability of the domestic gas boiler and some problems needing attention in its design.

Applying pulse combustion technology, developed a kind of low NOx exhaust residential boiler which is suitable for outdoor setting.

Unit heating is a preferable way and the market accepts residential boiler gradually, which lead to the development of the concept of "family hot water center".
