Water Heater Installation
We replace failed or aging tank water heaters and install new ones, gas or electric. Each new tank is sized for the home and strapped the way California law requires.

A tankless water heater has no tank of hot water waiting. It heats water only while a hot tap runs. A sensor picks up the flow and turns the heat on, and the heat shuts off when the tap closes. That skips the heat a tank loses while it sits.
As a plumber in Salinas, ASC Plumbing installs tankless water heaters for homes and businesses around the Monterey Bay Area. We handle conversions from a tank, and we repair and flush units already on the wall. Would you rather keep a tank? We do water heater installation as well.
Tell us about the leak, clog, water heater or repipe and where the property is. We look at the job and put the quote in writing.
Sizing comes first. The Department of Energy says to size a unit by the most hot water used at one time. It also depends on the heat rise, from cold winter water up to your set temperature.
The gas line has to keep up, and one maker's installation manual sets the rule. The line must feed the heater at full fire and every other gas appliance at once. The line that fed an old tank may be too small for that.
An indoor unit gets a new vent. That manual says it must not tie into an existing vent or chimney. Condensing units usually vent through plastic pipe and need a drain for the water they make. On the water side, isolation valves go in so the unit can be flushed later.
Tankless water heater maintenance clears out the scale that builds up inside the unit. Hard water leaves minerals in the heat exchanger, and a high temperature setting speeds that up. One maker's manual calls for a yearly inspection by a trained professional. It warns that skipping the flush will damage the heat exchanger.
How often depends on your water, and that manual says hard water may call for more frequent flushing. Marina Coast Water District says its well water carries increased hardness from natural minerals. The district recommends regular flushing for a tankless or tank water heater, as the maker advises. Your own water provider's yearly report lists your hardness.
A flush shuts the water off at the isolation valves and hooks a small pump to the service valves. The pump moves a descaling solution, such as food-grade white vinegar, through the unit for at least an hour. Fresh water then rinses it out, and the inlet water filter gets cleaned. Some units can show a service reminder on the display when a flush is due.
A tankless unit often flags a problem with an error code on its display. We read the code and trace it to the cause. Causes can include a clogged inlet filter, scale in the heat exchanger, a blocked vent and a full condensate trap.
Ignition faults can trace to parts such as the igniter, the flame rod, the gas valve or the circuit board. Some repairs are a cleaning, and some need a new part. A heater with a tank falls under water heater repair instead.
Salt air adds wear near the coast. One maker's manual says coastal installs may need extra upkeep because of airborne ocean salt. If the cabinet shows corrosion, it calls for an inspection and a repair or replacement as needed. Homes on the Monterey Peninsula and along the bay get that salt air.
