🔥 Gas Tankless Installation
Whole-home gas tankless units from Navien, Rinnai, and Rheem. We assess your gas line capacity and venting options before recommending a unit sized for your household's actual demand.
⚡ Electric Tankless
Point-of-use electric tankless units for single fixtures — ideal for a bathroom addition, garage, or workshop where running a full gas line doesn't make sense.

Error codes, ignition failures, cold water sandwiches, and mineral scale buildup in the heat exchanger — we diagnose and repair all major tankless brands.
🧹 Annual Descaling
Mineral buildup in the heat exchanger is the #1 cause of tankless unit failure. Annual descaling keeps the unit running at full efficiency and extends its 15–20 year lifespan.
🔩 Gas Line Upgrades
Most whole-home tankless units need a larger gas supply line than a standard tank heater. We handle the gas line upgrade as part of the installation — no separate contractor needed.
🏠 Tank-to-Tankless Conversion
Replacing a failed or aging tank water heater is the most common moment to go tankless. Same labor, better result. We handle the full conversion including venting changes.
Tankless vs. Tank: What Actually Matters for Beaverton Homeowners
- Endless hot water — a tankless unit never runs out, no matter how many showers you take back to back
- 20–30% lower energy costs — you only heat water when you use it, not 24/7
- 15–20 year lifespan vs. 8–12 years for a standard tank
- Wall-mounted — frees up floor space in utility rooms, garages, and closets
- No standby heat loss — tank heaters constantly reheat water that sits and cools
- Higher upfront cost — typically $2,300–$4,300 more than a tank replacement installed
Signs It's Time to Consider Tankless in Beaverton
- Your household regularly runs out of hot water — especially with multiple bathrooms
- Your current tank water heater is 10+ years old and needs replacement anyway
- You want to reduce your energy bill and your current heater is a major consumer
- You're finishing a basement or adding a bathroom and need more hot water capacity
- Your utility room is cramped and a wall-mounted unit would free up valuable space

Tankless Repair, Service & Descaling
Most tankless calls we take in Beaverton aren’t installations — they’re units already on the wall that have stopped behaving. A tankless heater is a good system that is genuinely unforgiving about maintenance, and almost everything below traces back to that.
Descaling
The single most important service a tankless unit gets. Mineral scale builds inside the heat exchanger, restricts flow, and forces the unit to work harder for less hot water. Most manufacturers call for it annually — and skipping it is the most common reason a tankless underperforms years before it should.
Hot water that comes and goes
Warm, then cold, then warm again mid-shower. Usually scale restricting flow, a fouled inlet filter, or a unit undersized for how many fixtures are running at once.
Unit shuts down under load
Fine for one shower, quits when the dishwasher starts. Often a gas supply that can’t deliver the BTU the unit demands — a supply-line sizing problem rather than a fault in the heater.
Error codes
Tankless units self-diagnose and display a code. That code narrows the cause considerably before anyone opens the cover — have it ready when you call and the visit gets shorter.
Venting and combustion
Improper venting shows up as nuisance shutdowns and is a safety matter, not a comfort one. Worth checking on any unit that keeps faulting for no obvious reason.
Inlet filter and flow sensors
Cheap parts that cause expensive-feeling symptoms. Often the actual fix on a unit an owner had assumed was failing.
What Tankless Repair & Service Costs in Beaverton
Repair and annual descaling are billed as labor plus parts, separately from installation. Estimates are free.
- Mon–Fri, 8am–4pm — $185/hour + parts & materials
- Mon–Fri, before 8am or after 4pm — $462.50 minimum (call-out + first hour), then $185/hour
- Saturday & Sunday, all day — $462.50 minimum (call-out + first hour), then $185/hour
If your gas supply can’t carry the unit’s BTU demand, no repair to the heater fixes it — that’s a supply-line job. See gas line repair in Beaverton →.
Frequently Asked Questions
How much does tankless installation cost in Beaverton?
A whole-home gas tankless installation in Beaverton typically runs $4,000–$6,000 depending on the unit, existing gas line size, and venting requirements. This is more upfront than a standard tank replacement, but most homeowners recover the difference in energy savings within 3–5 years. We provide a written estimate before anything starts.
Will a tankless unit work in my Beaverton home?
Most Beaverton homes with natural gas can support a whole-home tankless unit. The key question is whether your existing gas line has enough capacity for the BTU demand. We assess your current setup before recommending a unit — we won't sell you a system that can't keep up with your household.
What brands do you install in Beaverton?
We primarily install Navien, Rinnai, and Rheem — all three have strong warranties and reliable parts availability in the Portland metro. We'll explain the trade-offs between brands honestly based on your home's setup and your budget.
How long do tankless water heaters last in Beaverton?
Gas tankless units typically last 15–20 years with annual maintenance — roughly double the lifespan of a standard tank. Annual descaling of the heat exchanger is the most important maintenance step and keeps the unit running at full efficiency.
How much does tankless water heater repair cost in Beaverton?
Repairs and descaling are billed at our published labor rate rather than a flat fee: $185/hour plus parts and materials Monday to Friday 8am-4pm, or a $462.50 minimum covering call-out and the first hour then $185/hour outside those times. That's separate from installation pricing. Estimates are free, and if we find the unit isn't worth repairing we'll say so rather than working through parts.
How often does a tankless water heater need descaling?
Most manufacturers specify annually, and that guidance is worth following rather than treating as optional. Scale accumulates inside the heat exchanger whether or not the unit is showing symptoms; by the time you notice reduced flow or temperature swings, it has usually been building for a while. Annual descaling is also commonly required for warranty coverage to remain valid.
My tankless unit runs out of hot water when two things run at once. Is it broken?
Usually not. That's the classic signature of either a unit sized for fewer simultaneous fixtures than the household actually uses, or a gas supply line that can't deliver the BTU the heater demands under full load. Both are solvable, but neither is a repair to the heater itself — which is why a diagnosis matters before anyone replaces parts.
What does an error code on my tankless heater mean?
It depends on the manufacturer, but the code is genuinely useful — tankless units self-diagnose, and the code narrows the cause substantially before anyone opens the unit. Write it down before you power-cycle the heater, because clearing the fault also clears the code. Tell us the code when you call and the visit tends to be shorter and cheaper.
Is tankless actually worth it in a Beaverton home?
It depends on the household more than the house. Endless hot water and the recovered floor space are real, and so is the longer service life. But tankless demands annual descaling, often needs a gas supply upgrade, and costs more up front. For a household that runs several fixtures simultaneously and will keep up the maintenance, it's a good system. For one that won't service it, a well-maintained tank is the more honest recommendation.
