Common Issues We Catch With Tankless Water Heaters

Tankless water heaters run more efficiently than traditional units, but they still develop issues over time that can go unnoticed until you're left without hot water. At Prospector Plumbing & Heating, our technicians know exactly what to check for on every tankless system. Here are some of the most common issues we find:

Mineral scale buildup

On heat exchangers, especially in areas with hard water, reducing efficiency and flow

Clogged inlet water filters

That restrict water flow and trigger error codes or reduced performance

Faulty flow sensors

Causing the unit to fail to ignite or deliver inconsistent water temperature

Venting issues

On gas units, including blockages or improper installation that affect safety and performance

Ignition or burner problems

Leading to delayed hot water or a complete loss of heating

Undersized units for household demand

(resulting from corrosion buildup in the hot water heater, improper insulation, or loose electrical connections

Our Tankless Water Heater Process

Tankless Water Heater FAQ

Is a tankless water heater worth it in Alaska?

For most Fairbanks homeowners, yes. Tankless units use less energy, last longer (20+ years vs. 15 for tanks), provide endless hot water, and take up much less space. The higher upfront cost is typically offset by long-term energy savings.

Do you install both gas and electric tankless water heaters?

Yes. We install all types of tankless water heaters, gas and electric, all makes and models. Gas units are more powerful and better for high-demand households. Electric units are simpler to install and ideal for smaller homes or supplemental systems. We'll help you choose the right fit.

Can you repair my existing tankless water heater?

Yes. Our plumbers are trained on all makes and models of tankless water heaters. We repair ignition issues, error codes, flow sensor failures, scale buildup, temperature fluctuations, and more, usually same day.

How often does a tankless water heater need maintenance?

We recommend annual maintenance for most tankless systems. Alaska’s water quality can cause mineral scale to build up in the heat exchanger over time, reducing efficiency. Annual service keeps the unit running clean and extends its 20+ year lifespan.

What areas do you serve for tankless water heater services?

We serve Fairbanks, North Pole, the Mat-Su Valley, and surrounding areas. We know Alaskan homes and dispatch experienced local plumbers quickly to handle any tankless installation, repair, or maintenance.

How do I schedule tankless water heater service with Prospector?
