Tankless Water Heater Installation

A tankless water heater heats water only when you need it — no tank to keep hot, and no running out halfway through a shower. Zenith installs and services tankless units, sized for your home and set up for Colorado's elevation.

Benefits of Going Tankless

  • Continuous hot water within the unit's flow capacity
  • Saves floor space with a wall-mounted unit
  • No standby energy spent keeping a tank hot
  • Longer expected lifespan with regular maintenance

Our Tankless Water Heaters Process

  1. Calculate the flow rate your household needs
  2. Check gas line size, venting and electrical requirements
  3. Select a unit rated for your elevation
  4. Install, vent and connect the unit
  5. Test and explain recommended maintenance

Things to Consider

Tankless is a great fit for many homes, but it's not automatic. A few things to weigh:

Upfront cost
Units and installation usually cost more than a tank replacement.
Gas supply
Many units need a larger gas line than a standard tank.
Simultaneous use
Size the unit for how many fixtures run at once.
Maintenance
Periodic descaling keeps it efficient, especially with harder water.

Frequently Asked Questions

Do tankless water heaters work at Colorado's altitude?

Yes, when they're selected and set up for it. Gas appliances need to be rated or configured for high altitude, which we account for during installation.

How often should a tankless unit be flushed?

Typically about once a year, or more often with harder water. Flushing removes scale that reduces efficiency.
