Tankless Water Heater Installation in Tustin Meadows

Three, mainly. The up-front cost, estimated at $4,500 to $7,500 locally for a conversion, because the gas line and venting often have to change. Periodic flushing to keep scale off the heat exchanger. And a short burst of cooler water between back-to-back uses. Against those: no tank to fail, no floor space taken, and hot water that does not run out.

An estimated $4,500 to $7,500 for a tank-to-tankless conversion in this part of Orange County. National figures start nearer $2,400, but those rarely include a larger gas line or new venting, which are the two items that most often decide the real price.

Not usually, but it is telling you something. Rumbling or popping as the burner fires is sediment on the bottom of the tank, where water trapped under it boils in small bursts; it costs efficiency and strains the tank over time, and a flush often helps on a younger tank. A tea-kettle whistle can be a restricted valve or scale. Hissing or sizzling can be water dripping onto a burner or an element, which is worth a look soon. What deserves an immediate call is noise together with a relief valve that is discharging — leave the valve alone and turn the heater off.

About ten to twelve years for a tank, and the label on the side gives its manufacture date. Tankless units generally last longer. In Tustin that number is easy to set against the house: Tustin Meadows was built from 1967, Peppertree from 1973, Tustin Ranch from the mid-1980s and Tustin Legacy from 2006 — which means the first heaters in Tustin Legacy are reaching that age now. The warning signs usually come before failure: hot water running out sooner, rumbling, rust on the hot side, a weep at the base.
