Tankless water heaters heat water on demand instead of storing it, which means you never run out mid-shower and you're not paying to keep 50 gallons hot all day. For many Brentwood homes — especially larger newer builds with multiple bathrooms — a properly sized tankless unit is the upgrade that pays off in efficiency and lifespan. The catch is that tankless done wrong performs poorly: it needs adequate gas line capacity, correct venting, and sizing in gallons-per-minute (GPM) to your peak demand. We get those details right so your unit delivers on its promise.
Where we see installs go sideways is sizing and gas supply. A unit that's undersized for a four-bathroom home will struggle to keep two showers hot at once, and an existing ½" gas line often can't feed a high-demand tankless unit at all. We calculate your real peak GPM, verify or upsize the gas line, route condensate properly on condensing models, and — because Brentwood's water is hard — set the unit up with isolation valves so annual descaling is quick. The result is a tankless system that actually performs the way the brochure promised, for 20 years or more.
What’s included
- GPM sizing to your home's peak hot-water demand
- Gas line capacity check and upgrade if needed (¾" minimum)
- Correct venting and condensate handling for condensing units
- Wall-mounting, connections, and code-compliant install
- Isolation valves fitted for easy future descaling
- Permit, inspection, and a homeowner walkthrough
Signs you need tankless water heater installation
- You keep running out of hot water with a tank unit
- You want lower energy bills and a 20+ year lifespan

- You're converting from an aging tank system
Brentwood code note: Tankless installs are permitted and inspected like any water heater. Gas line sizing and venting are the most common code issues we correct on conversions.
What affects your price
We never quote blind. After a free on-site assessment you get one clear, upfront price — no surprises. The main factors:
- Condensing vs. non-condensing and required GPM
- Gas line upsizing and venting work
- New install vs. tank-to-tankless conversion
- Brentwood's hard water (descaling provisions and bypass valves)
