Molded parts
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 extremely rapid drying and water immersion environments; it has better performance than traditional ceramic fiber boards.
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.

The vermiculite board uses expanded silver vermiculite of 0.3-1mm as the raw material, is bonded with an inorganic mixture, pressed under high pressure, and dried for several hours to make a fireproof insulation board with good strength.
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.
