⚡ 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 Hillsboro 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

Energy savings in Hillsboro: Hillsboro homeowners with larger homes and higher hot water demand see the biggest savings with tankless — often 25–35% on water heating costs. Over the 15–20 year lifespan of a tankless unit, that adds up to real money — and the unit typically lasts long enough to make the higher upfront cost worth it for most households.

Signs It's Time to Consider Tankless in Hillsboro

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
