The primary advantage of Gas Continuous Flow Hot Water technology is its space-saving design and high energy ratings. In fact, most modern units achieve a 6-star energy rating or higher, significantly reducing your household’s gas consumption. In addition, because the units are compact and wall-mounted, they are ideal for homes with limited outdoor space or narrow side-passages. Moreover, you only pay to heat the water you actually use, rather than heating a massive tank all day while you are at work. As a result, many homeowners see a noticeable decrease in their energy bills after switching from an old electric storage tank. Additionally, the absence of a large water storage tank eliminates the risk of a major flood if the cylinder were to ever fail.
