Item 4.01  Changes in Registrant’s Certifying Accountant; Dismissal of Independent Auditors

As previously reported on September 10, 2015, Heatwurx, Inc., a Delaware corporation (the “Company”), was informed by Hein & Associates LLP notifying the Board of Directors that the Company’s auditor/client relationship with Hein & Associates LLP had ceased. Prior to the receipt of the Hein & Associates LLP letter on September 3, 2015, the Company had not been informed by Hein & Associates LLP that Hein & Associates LLP desired to terminate its independent auditor/client relationship with the Company.

From inception through September 3, 2015, there have been no disagreements with Hein on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Hein & Associates LLP, would have caused it to make reference thereto.

This 8-K filed on September 10, 2015 is being amended to clarify that during the audit of our 2014 financial statements, Hein & Associates LLP advised the Company of a material weakness related to the Company’s internal control over financial reporting. This communication advised the Company that the internal controls necessary to develop reliable financial statements does not exist.
