CFV Heat Retention Rings

CFV Heat Retention Rings

Replacement Heat Retention Rings.  Compatible only with the Boundless CFV.




*Only for the Pre-August 2018 CFV that does not feature the new stainless-steel chamber.

The Quartz heat retention ring introduces an element of thermal radiation to the full convection experience. Quartz reflects heat into the chamber causing thermal radiation to heat the chamber and stay there while our wood heat retention rings absorbs heat in the chamber to only allow convection aromatherapy. Using the quartz ring will allow your chamber to heat up faster and retain heat better than the wood heat retention rings but sacrifices flavor that only a full convection experience gives the user.

All Boundless Technology, LLC products are backed by a 3-year manufacturer warranty.


There is a separate 90-day warranty on the battery.

To claim a warranty please have the proof of purchase and original box the unit came in as it contains a security code needed for the warranty process. If you would like to get the warranty process visit our Warranty Page.
