The condensing boiler includes a heat pipe-type air heater and an economizer to retrieve the hidden heat from discharged gas and vapor and to improve the energy efficiency by more than 100%.  
This all-in-one type equipment includes a fan, a water pump, a control panel and a continuous blow device. Simple on-site works.  
A simple structure and easy cleaning, inspection and maintenance. In particular, it is simple work to replace the smoke tube.  
The air preheater and the economizer attached to the main body saves installation space and costs and guarantees high performance. Depending on the condition of the site, you may select just one of the air preheater or the economizer.
