This article will discuss how a new breed of condensing boiler is challenging conventional practices and supporting new approaches to improve the cost and energy efficiency. Now, horizontal condensing boiler manufacturer, ZG will analysis condensing boiler advantages for you as below:
 

Increased efficiency
Today's high-efficiency condensing boilers are engineered to condense. Their heat ex-changers are made of high-quality materials and designed to drain freely, which allows them to withstand years of condensing operation with no significant corrosion. Some equipment even can withstand thermal shock caused by rapid temperature changes. Consequently, condensing boiler equipment can be incorporated into a main loop directly. Without piping, pumps, mixing valves, and other components historically used to protect boilers from cool return water, condensing boilers simplify hydronic loops and reduce project and maintenance costs.

Improved comfort and control
The highest-efficiency boilers combine accurate temperature control with high burner turn-down to precisely and cost-effectively match plant output to heating demand. These boilers may use a PID controller to maintain supply-water temperature to within ±2°F. After load and temperature requirements are determined, these PID controllers modulate high-turn-down burners in 1-percent increments. This allows boilers to change input/output to match load exactly. There is no temperature overshoot, and these boilers can operate over their entire range in a matter of seconds. Such high turn-down, coupled with latent energy recaptured during condensing, can generate as much as a 30-to-40-percent increase in efficiency, compared with conventional hydronic systems. The high efficient boiler is developed by horizontal boiler manufacturer, ZG boiler, on the base of 70 years' experience on boiler designing.
Such part-load efficiency can be leveraged even further with a boiler-management system. In some cases, both a boiler management system individual unit controllers provide access to comprehensive operating information to support advanced energy-management programs, allowing system designers to leverage indoor/outdoor-reset schedules, remote set points, and even full integration into building-automation software to maximize fuel savings.

Saving space
Setting aside adequate building and mechanical-room space to support conventional boilers has been a long-standing challenge of building design. While the emergence of modular equipment has helped, there still are significant material and construction expenses associated with the atmospheric intake ducting, natural-draft exhaust venting, and fixed-flow pumping requirements of conventionally designed boilers.
