Due to its financial strength and backing by its strong major shareholders, Gasmaster adopted a very conservative approach to marketing its product. Although the manufacturing facility was equipped with state-of-the-art computer controlled production equipment, all required certifications were obtained, and the field units installed in 1994 were working perfectly, the company limited its activities to the local market only. During the first four years of its operation, Gasmaster produced less than 40 units for a handful of carefully selected projects. These projects allowed the company's engineers to closely monitor the performance of the boilers in a range of applications and try to "perfect" any and all possible features of the product, before embarking on a national and eventually North American marketing campaign. In 1999 the company filed and was granted new patents on its products. The new international patents cover a wide range of features, which include: combustion process, product configuration and the unique automatic throttle mechanism.

As a result of over 15 years of concentrated R&D work, more than $15 million investment in product development and production equipment, the company is now capable of offering a complete line of 26 models of boilers and water heaters with unparalleled performance and quality, bar none.
