How a Tankless Water Heater Works

When a hot-water fixture opens, water flows through the tankless unit. The equipment activates and heats the moving water according to its design and capacity.

Tankless performance depends on:

• The water-flow rate
• The incoming water temperature
• The selected outlet temperature
• The number of fixtures operating simultaneously
• The unit’s heating capacity
• The available gas or electrical supply
• Water quality and internal scale

A tankless unit does not provide unlimited flow. It must be capable of heating the amount of water being requested at a given time.

Is a Tankless Water Heater Appropriate for Your Property?

A tankless system may be suitable for some properties, but it is not automatically the best option for every home or business.

An evaluation should consider:

• Current and expected hot-water demand
• Number of bathrooms
• Simultaneous fixture use
• Existing gas or electrical capacity
• Available venting options
• Incoming water conditions
• Equipment location
• Available wall and service space
• Existing pipe layout
• Applicable permit and inspection requirements

Benefits of Tankless Water Heating

Potential benefits can include:

• No large storage tank
• Hot water produced during use
• A more compact equipment footprint
• Reduced standby heat associated with stored water
• Installation flexibility in some properties
• Capacity options for residential and commercial demand

Actual performance and energy use depend on the equipment, installation, water demand and property conditions.

Tankless Water Heater Limitations

Property owners should also understand the limitations and installation requirements of tankless equipment.

Possible considerations include:

• Maximum flow capacity
• Temperature changes during high simultaneous demand
• Gas-line or electrical upgrades
• Venting requirements for applicable gas systems
• Water-quality and scale considerations
• Minimum flow requirements
• Equipment-specific service needs
• Changes needed when replacing a tank system

A smaller physical size does not mean the equipment has simple energy or installation requirements.

Tankless Water Heater Sizing

Tankless sizing is based largely on required flow and temperature rise. The unit must heat incoming water to the desired outlet temperature while the expected fixtures are operating.

Potential Residential Hot-Water Demand

• Showers
• Bathtubs
• Bathroom sinks
• Kitchen sinks
• Dishwashers
• Washing machines
• Several fixtures operating simultaneously

Potential Commercial Hot-Water Demand

• Restrooms
• Commercial kitchens
• Cleaning operations
• Tenant use
• Business equipment
• Peak operating periods

A unit sized for one shower may not support several showers and appliances operating simultaneously. Actual fixture flow should be considered.

Temperature Rise and Incoming Water

Temperature rise is the difference between incoming cold-water temperature and the desired hot-water temperature. Greater temperature rise requires more heating capacity at the same flow rate.

Incoming water conditions can vary with season, water source and property. Equipment should be selected using realistic conditions rather than only a maximum advertised flow figure.

Gas Tankless Water Heater Installation

Gas tankless water heaters can require substantial fuel input while operating. The existing gas system must be evaluated for the selected equipment and other connected appliances.

Installation considerations may include:

• Gas-line size and capacity
• Existing appliance demand
• Equipment input requirements
• Venting type and route
• Combustion-air requirements
• Equipment clearances
• Condensate handling for applicable models
• Water connections
• Applicable permits and inspections

The presence of an existing gas water heater does not automatically mean the current gas line can support a tankless replacement.

Electric Tankless Water Heater Installation

Whole-house electric tankless water heaters can require significant electrical capacity. The property’s panel, service and circuits must be suitable for the selected equipment.

Installation considerations may include:

• Voltage
• Total electrical demand
• Panel capacity

• Disconnecting provisions
• Equipment location
• Water connections
• Applicable permits and inspections

Electrical work should be completed by an appropriately qualified provider when required.

Gas vs. Electric Tankless Water Heaters

Gas Tankless Systems

• Require a suitable gas supply
• May require specialized venting
• Can offer different capacity ranges
• May produce condensate depending on the equipment
• Require appropriate combustion and safety provisions

Electric Tankless Systems

• Do not require combustion venting
• Can require substantial electrical capacity
