Winter Warmth Assurance is an extended product warranty, not a service contract, and it does not cover the cost for annual maintenance or boiler cleaning. However, your installer may provide “service contracts” to cover these very important service functions, as a supplement to your Winter Warmth Assurance extended warranty.
Burnham recommends that you have your boiler inspected and serviced annually, or as necessary, to make certain your Burnham boiler runs smoothly, safely, and provides the comfort, efficiency and reliability you deserve.
