Marc Caluwe has been designing and making wood stove boilers on a craft basis, working purely in heavy gauge steel, since 1993. Over that time we have evolved radically different designs from the norm, that have stood the test of time as well as performance. We hope that this site gives an idea of the variety and invention that we feel we bring to a rather conservative industry sector. Much of this time also has been spent working closely with builders and architects to help customers find the right hearth appliance for their home.

Because we don't have capital tied up in expensive machinery, we can afford to be more adventurous than the big manufacturers. We can go from an idea to a preliminary test model within 15 days of the first sketch! We build by hand, taking ideas that first formed on the shop floor, that over the years have evolved into the basic models that we now offer; each radically different from anything else on the market, but each with a proven track record of performance, reliability and longevity.

For more information about our models, please brows our website to get a better understanding of our indoor wood stove boilers with visible fire or contact us by e-mail or by phone.

We are looking to expand the business, to take advantage of some of the new designs we have developed, and are inviting approaches for either equity or business involvement from suitable other parties. Please call Marc Caluwe @ 781-308-8583 or send an e-mail in confidence to
