Tankless Water Heater Benefits
Tankless water heaters can be a good fit for many homes and businesses when they are properly sized and installed. Common benefits include:
- On-Demand Hot Water - Water is heated as it is needed rather than stored in a tank.
- Space Savings - Tankless units are compact and can free up floor space compared with many traditional water heaters.
- Potential Energy Savings - Because water is not continuously stored and reheated, a properly selected tankless system may reduce standby energy loss.
- Long Service Life - With proper maintenance, many tankless systems can provide a long service life.
- Flexible Fuel Options - Depending on the property and application, tankless systems may be available in natural gas, propane, or electric configurations.
Tankless Water Heater Efficiency and Operating Costs
Tankless water heaters can reduce standby energy loss because they heat water only when it is needed rather than keeping a full tank hot around the clock. Actual operating costs depend on the fuel source, household demand, unit efficiency, local utility rates, and how the system is sized and used.
The biggest advantage comes from choosing the right unit and installing it correctly. Marc Francis Plumbing evaluates factors such as hot water demand, fuel type, gas supply, electrical requirements, venting, and existing plumbing so the system is set up for efficient, reliable operation.

Choosing the Right Tankless Water Heater for Your Home
Choosing the right tankless water heater involves more than simply selecting a brand or model. The system must be properly sized for your household's hot water demand and matched to the home's available fuel source, plumbing, gas supply, electrical requirements, and installation conditions.
Important factors include:
- Household Hot Water Demand: The number of fixtures and appliances that may need hot water at the same time helps determine the required flow rate.
- Fuel Source: Tankless water heaters may operate on natural gas, propane, or electricity. The existing utilities and the requirements of the selected unit must be evaluated before installation.
- Proper Sizing: Flow rate and required temperature rise are important when determining which tankless water heater can reliably meet your home's needs.
- Installation Requirements: Gas line capacity, venting, electrical service, water connections, and installation location can all affect which system is appropriate for the home.
Marc Francis Plumbing evaluates these factors before recommending a tankless water heater. With more than 40 years of hands-on plumbing experience, Marc can help homeowners choose a system that provides dependable hot water without unnecessarily oversizing the equipment.
Properly Sizing a Tankless Water Heater
Proper sizing is one of the most important parts of choosing a tankless water heater. Unlike a traditional tank that stores a set amount of hot water, a tankless system must be able to heat water as it flows through the unit.
Two important factors are flow rate, measured in gallons per minute (GPM), and temperature rise. Flow rate is determined by how many hot-water fixtures may be used at the same time. Temperature rise is the difference between the incoming water temperature and the desired hot-water temperature.
For example, a household using a shower, sink, and another hot-water appliance at the same time may require considerably more capacity than a home where hot-water demand is typically limited to one fixture at a time.
Gas-fired tankless systems may also require evaluation of the home's existing gas piping. A new unit can have a significant BTU demand, and the gas supply must be properly sized to support the water heater along with other gas appliances in the home.
Marc Francis Plumbing evaluates the home's hot-water demand, incoming water conditions, fuel supply, and existing plumbing before recommending a tankless system. Proper sizing helps provide reliable hot water while avoiding an undersized or unnecessarily oversized unit.
