Tankless Water Heater Installation in Gresham, Oregon
A tankless water heater heats water on demand instead of keeping 40–50 gallons hot around the clock. The result: endless hot water, lower energy bills, and a unit that lasts twice as long as a standard tank. True Flow Plumbing installs and services tankless units throughout Gresham.
Tankless Water Heater Service in Gresham
Gresham homeowners replacing aging water heaters are increasingly considering tankless as the cost premium has come down. For households where the water heater is in a tight space — a closet or small utility room — a wall-mounted tankless unit frees up significant floor space while providing better performance. We carry and install Rheem and Rinnai tankless units and handle all associated gas line and venting work.
🔥 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.
🔧 Tankless Repair & Service
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 Gresham 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 $1,000–$2,000 more than a tank replacement installed
Signs It's Time to Consider Tankless in Gresham
- 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
