Condar Combustors are slightly higher priced than our other combustors for one very good reason. The Warranty. All Condar Combustors are covered 100% for the first year and at a prorated amount until the 5th year of use when correctly installed and maintained.

Year 2 - 35% rate

Year 3 - 50% rate

Year 4 - 75% rate

Year 5 - 90% rate

What that means to you is if you purchased a $100 combustor and it failed in year 3 you would pay $50 for a replacement while the other half would be covered by the warranty.
