Ottawa water leaves sediment in the bottom of a tank and scale inside a tankless unit. An annual service clears both, and it is the difference between a tank lasting eight years and twelve.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Tank Flushed<\/h3>

    Sediment settles on the bottom, directly above the burner. It steals capacity, makes the burner work harder and is the most common reason a tank fails early.<\/p><\/article>

    <\/path><\/svg><\/span>

    Anode Rod Inspected<\/h3>

    The sacrificial rod that corrodes so the tank does not. Replacing a spent rod is inexpensive; replacing a rusted-through tank is not.<\/p><\/article>

    <\/path><\/svg><\/span>

    Relief Valve Tested<\/h3>

    The safety device that stops a tank becoming a pressure vessel. Rarely thought about, occasionally seized, and worth two minutes a year.<\/p><\/article>

    <\/path><\/svg><\/span>

    Burner and Venting Checked<\/h3>

    On gas units we confirm clean combustion and that the flue is drawing properly. This is a safety check, not an efficiency one.<\/p><\/article>

    <\/path><\/svg><\/span>

    Tankless Descaling<\/h3>

    Hard water leaves scale inside the heat exchanger, which shows up as reduced flow and fluctuating temperature long before it shows as a fault.<\/p><\/article>

    <\/path><\/svg><\/span>

    Temperature Verified<\/h3>

    Set high enough to be safe from bacteria, not so high it scalds. Most tanks we see are set higher than they need to be, which costs money every day.<\/p><\/article><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Why Ottawa Water Makes This Matter<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Sediment accumulates in every tank, but the rate depends on water hardness. In this region it builds fast enough that a tank left unflushed for a decade can lose a noticeable share of its usable capacity \u2014 you run out of hot water sooner and never quite work out why.<\/p>

    The same minerals form scale inside a tankless heat exchanger. There the symptom is different: flow drops and the temperature starts to swing during a shower. Descaling restores it. Left long enough, it does not.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • A tank that reaches twelve years instead of eight<\/li>
    • Full hot water capacity rather than a slowly shrinking supply<\/li>
    • Lower running cost, because the burner is not heating through a layer of sediment<\/li>

      Once a year for both tank and tankless. Tankless units in hard water sometimes benefit from more frequent descaling.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      You can, and it helps. A service also covers the anode rod, the relief valve and the combustion check, which are the parts that matter for safety.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
