thermal battery
The heat chamber is the heart part of the condensing boiler, which determines the service life of the condensing boiler.The 1200℃ vermiculite board can withstand the environment of extremely rapid drying and water immersion; it has better performance than traditional ceramic fiber board.
condensing boiler
The ideal service life of a condensing boiler is about 12-15 years, and the heat battery at the heart determines whether it can achieve the ideal life. The use of high-quality vermiculite board can reduce the number of hot core replacements and reduce the worries of users.
For use under harsh conditions, vermiculite boards have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by volatile alkalis and some slags.
