Water Heater Installation in Knoxville, TN — Tank & Tankless
Installing a new water heater is one of the highest-impact plumbing upgrades a Knoxville homeowner can make — and one where the quality of the installation matters as much as the unit itself. A properly installed water heater runs efficiently, lasts longer, and doesn't void the manufacturer warranty. Honey Bear Plumbing provides professional water heater installation throughout Knoxville and Knox County, with upfront pricing and same-day service on most installations.
We install all major brands of tank and tankless water heaters, handle all required permits, and clean up completely when the job is done.
Tank Water Heater Installation in Knoxville
Standard tank water heaters remain the most common choice for Knoxville homes. They're cost-effective upfront, reliable, and straightforward to service. We install 30, 40, 50, and 80-gallon units from all major manufacturers.
What's included in our installation:
- Removal and disposal of old unit
- Installation of new unit to code
- Connection of supply lines and discharge
- Pressure relief valve installation and test

Tankless Water Heater Installation in Knoxville
Tankless (on-demand) water heaters heat water only when you need it — no standby heat loss, no running out of hot water, and lifespans of 15–20+ years with proper maintenance. They cost more upfront but pay back over time in energy savings.
Tankless installation considerations:
- Gas units require proper venting (direct-vent or power-vent)
- May require gas line upgrade for high-BTU units
- Electric tankless may require electrical panel upgrade
- Water softener recommended in areas with hard water
We assess your home before recommending a unit so there are no surprises.
