Tankless water heater installation
Gas line sized properly, new venting, condensate handled, isolation valves fitted so the next descale is twenty minutes.
Tankless installation across Orange County, from Orange
A tankless conversion is a bigger job than swapping a tank, and anyone who tells you otherwise is about to do it wrong. A tankless unit fires at a far higher input than a tank, so the gas line usually has to be upsized. A half-inch run that fed a 40-gallon tank will starve a tankless unit and you will get error codes instead of showers. Venting changes too: condensing units need their own sealed stainless or PVC vent and a condensate drain with neutralisation, not the old B-vent up the chimney.
We do the gas load calculation before we quote, not after. If the meter or the line makes the conversion uneconomic, we tell you on the first visit.
What we always fit
Isolation and service valves on the inlet and outlet. They add a small amount to the install and they turn every future descale into a twenty-minute job instead of a two-hour one. Plus a sediment filter on the cold inlet, because Orange County water is hard and the heat exchanger is the expensive part.
Time on site
A straightforward conversion is a full day. Gas-line re-runs or a relocation can make it two.

-
The permit, pulled by us
California requires a plumbing permit to replace a water heater, and the inspection is where the strapping, venting and relief valve all get checked. We pull it and we meet the inspector.
-
Two seismic straps
Upper third and lower third of the tank, lower strap at least four inches clear of the controls. Required in California, and the first thing an inspector checks.
-
Expansion tank on a closed system
Any house with a pressure regulator, check valve or backflow preventer at the meter is a closed system. Heated water expands, the expansion has nowhere to go, and it pushes the T&P valve open until something gives. The expansion tank absorbs it.
-
T&P discharge line done properly
Full-size pipe, run downhill, no valve on it, no threads on the end, terminating outside where a drip is visible.
-
Drain pan and drain line
Wherever a leak would reach drywall, ceiling or floor. Attics and upstairs closets always.
-
New water flex connectors, gas flex, shut-off valve and sediment trap
We do not reuse twelve-year-old brass.
24 Hour Emergency Service
We are available 24 hours a day, 7 days a week.

Questions about tankless installation
How long does a tankless conversion take?
A full day for a straightforward one. Two if the gas line has to be re-run or the unit is moving to a new wall.
Why does a tankless unit need a bigger gas line?
A tankless unit fires at a much higher input than a tank because it heats water on demand instead of over an hour. A half-inch line that happily fed a 40-gallon tank will starve it, and you get error codes instead of showers. We run the gas load calculation before quoting, not after.
What is descaling and how often does a tankless need it?
Hard water leaves calcium inside the heat exchanger. Descaling circulates solution through it for about forty-five minutes and brings the flow rate back. Roughly once a year on Orange County water, every two years if you have a softener.
What are service valves and do I need them?
Isolation valves on the inlet and outlet of a tankless unit. They add a little to the install and turn every future descale from a two-hour job into a twenty-minute one. We fit them as standard.
Why do I need an expansion tank?
If your house has a pressure regulator, check valve or backflow preventer at the meter, it is a closed system. Water expands when it is heated and on a closed system that expansion has nowhere to go, so it pushes the T&P valve open or stresses the tank. An expansion tank absorbs it. It is a code requirement on closed systems, not an upsell.
