Tankless Water Heater Installation, Repair & Maintenance
Tankless Water Heater Service
At Venice Cooling and Plumbing, we know that choosing the right hot‑water system for your home involves smart decisions. If you’re looking into a tankless water heater, you’ve come to the right place.

How Does a Tankless Water Heater Work?
A tankless water heater warms water only when you open a tap or shower. Unlike traditional water heaters that keep a large volume of hot water stored continuously in a tank, a tankless system uses a heat exchanger to rapidly heat water as it flows through the unit. The result? Endless hot water on demand, no storage tank, and reduced standby energy loss.

Tankless Water Heater Maintenance
Even the best tankless water heater benefits from regular maintenance. To keep yours running at peak efficiency:
- Flush the unit several times a year to remove scale buildup from hard-water
- Inspect the water filter and clean if necessary
- Check gas or electrical connections and venting for safe operation
- Monitor the water flow rate and temperature variation (any drop may suggest buildup or sensor issues)
- Schedule a professional inspection so that any wear-and-tear is caught early, preventing costly damage
By staying on top of your tankless water heater maintenance, your system will stay efficient and significantly reduce the need for service calls.
How to Change from a Tank to Tankless Water Heater
Thinking of upgrading? Converting from a tank to a tankless water heater involves several steps: assessment of your current system, selection of proper unit size (based on number of fixtures, bathrooms, simultaneous uses), checking venting and gas or electrical supply, disconnecting the old tank, installing new connections, and verifying that the system meets local codes. At Venice Cooling & Plumbing, our licensed plumbing team takes care of it all, so you don’t need to worry about hidden complications or voided warranties.
Benefits of a Tankless Water Heater
- Energy bill reductions of 10-30%: tankless systems only heat water on demand
- Extended system lifespan: many units last 15-20 years rather than a typical decade for traditional tanks
- Fewer emergency breakdowns: preventative care such as flushing sediment and inspecting sensors keeps your tankless water heater from needing frequent service
Tankless Water Heater vs Tank
The decision between a tankless and tank water heater is important and can be contingent on your personal needs. Traditional tank water heaters are reliable and budget-friendly, while tankless water heaters supply endless hot water on demand and energy savings. Other factors to consider when deciding include:
- Traditional tanks store hot water and continuously keep it at temperature, meaning energy is wasted heating unused water
- Tankless systems heat water only when needed, making them more efficient and compact
- Tankless units often last longer with better maintenance, while tanks can corrode and eventually leak.
- Installation of a tankless system may cost more upfront, but the long‑term savings and performance benefits often outweigh the initial investment.
