Tankless water heater maintenance — Boulder, CO
Last updated: September 24, 2026
What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
Even though tankless units don't have tanks, they still need regular care, specifically a descaling process to remove scale buildup in the heat exchanger. If you have hard water, this is essential to keep the unit running correctly and prevent error codes. Skipping this can lead to restricted flow or heating issues.

What is involved in installing an expansion tank on a water heater?
Installing an expansion tank on a water heater is a safety measure. It connects to the cold water line and provides space for water to expand when heated. This prevents excessive pressure buildup in your plumbing system, protecting pipes and the tank itself. Proper installation ensures your system operates safely and efficiently. A qualified technician can ensure it's installed correctly.
What are the most energy efficient water heater options for Boulder?
The most energy-efficient water heater options for Boulder include tankless models and heat pump (hybrid) water heaters. These systems minimize energy loss by heating water on demand or by using ambient air heat. They are ideal for residents looking to reduce their environmental footprint and utility costs. A professional can assess your home's needs and recommend the best efficient unit.
What should I do if my water heater is leaking?
If your water heater is leaking, the first step is to shut off the power or gas supply to the unit. Then, turn off the cold water inlet valve. If the leak is coming from the tank itself, it usually means the unit needs replacement. Leaks from pipe connections or the pressure relief valve might be repairable. It's crucial to call a professional immediately to assess the situation and prevent further damage.
