Tankless Water Heater Installation & Replacement
A successful tankless installation starts with the home—not just the equipment. Water Fixers evaluates hot-water demand, utility capacity, venting, water connections, location and serviceability before recommending a system.
Installing Tankless Is More Than Hanging a Box on the Wall
Tankless systems can require different planning than storage water heaters. The correct installation depends on the specific equipment and property, including available gas or electrical capacity, venting, water piping, condensate handling where applicable, service valves, recirculation needs, installation location and household flow demand.
Tank-to-Tankless Conversion
Many homes can be converted from a traditional storage water heater to tankless, but it should be treated as a system redesign rather than a simple equipment swap. Existing utility connections and venting should be evaluated before the new unit is selected.
We can also help homeowners compare whether staying with a storage heater or moving to tankless makes more sense for the property.
What We Evaluate Before Installation
- Expected simultaneous hot-water demand
- Required temperature rise
- Gas supply or electrical capacity
- Venting and combustion requirements for applicable equipment
- Condensate management for condensing models
- Water piping and service-valve layout
- Recirculation design where desired
- Installation location and future service access
Sizing Matters
Tankless systems are selected around flow and temperature rise, not just household square footage. A home that may run a shower, kitchen faucet and laundry at the same time can have very different peak demand from a home with similar size but different usage patterns.
Proper sizing helps prevent disappointment with hot-water delivery after installation.
Replacing an Existing Tankless Unit
We evaluate the existing setup and determine whether replacement can use the current location and infrastructure or whether changes are needed.
Converting From a Storage Tank
A conversion may involve utility, venting, piping or location changes. Those conditions should be evaluated before equipment is ordered.
Recirculation Options
Where appropriate, recirculation can improve hot-water delivery, but the design should match the home and selected equipment.
Already Own Tankless?
For no hot water, inconsistent temperature, error conditions or leaks, use the repair page.
Protect the New System
Routine maintenance and descaling should be planned from the beginning.

Tankless Water Heater FAQs
Can I replace my tank water heater with tankless?
Often yes, but the home should first be evaluated for hot-water demand, utility capacity, venting, water connections, installation location and any condensate or recirculation requirements.
Does a tankless water heater need a larger gas line?
Some installations may require changes to the gas supply, while others may not. Correct sizing depends on the equipment input requirements, developed pipe length, available pressure and other connected appliances.
Does a tankless water heater need electricity?
Many gas-fired tankless systems still require electrical power for controls, ignition and other components. Electric tankless systems have their own substantial electrical requirements.
Does tankless require special venting?
Gas-fired tankless equipment has manufacturer-specific venting requirements. The correct material, routing and termination depend on the unit and installation.
How do you size a tankless water heater?
Sizing considers expected simultaneous hot-water flow and the temperature rise needed between incoming water and the desired outlet temperature.
