Professional Heater - MHA is a professional association of masonry heater builders

The MHA is a professional association of masonry heater builders that was formed to advance the technology of masonry heating in North America and to increase the knowledge and skills of professional heater masons. The MHA fulfills its mandate by sponsoring laboratory research into masonry heating technology and by publishing information of interest to practitioners. The MHA also maintains a professional training and certification program to recognize the competency of qualified heater builders.

This manual has been prepared to assist candidates in achieving and maintaining MHA certification, and to guide the administration of the program. The requirements presented in this manual have been established by the MHA Board of Directors and it is its sole responsibility to apply and interpret them, primarily through its administrative designate. The manual may be amended from time to time to account for changing conditions.

To maintain MHA certification in good standing, a certificate holder must be a MHA full voting member and pay an annual renewal fee of $50. The fee covers administrative costs, validation of renewal and information updates. Failure to pay the annual renewal fee will result in the withdrawal of certification after two payment notices have been sent and no response is received by the administrator within 90 days.
