Why Choosing the Right Tankless Water Heater Matters #
A tankless water heater is an energy-efficient solution that provides on-demand hot water, eliminating the need for a storage tank. Unlike traditional water heaters, tankless models heat water only when needed, reducing energy consumption and ensuring you never run out of hot water. But how do you choose the best tankless water heater for your home?
At VMP HOME, we are a Rinnai Pro Dealer, offering top-rated Rinnai tankless water heaters designed for maximum efficiency and long-term savings. This guide will help you understand key factors in selecting the right tankless water heater, including sizing, fuel type, efficiency ratings, and installation considerations.
How Do Tankless Water Heaters Work? #
Unlike traditional water heaters that continuously heat and store water, tankless water heaters use high-powered burners to instantly heat water as it flows through the unit. This means:
- Unlimited Hot Water – Never run out of hot water again.
- Energy Savings – No standby heat loss, reducing utility bills.
- Compact Design – Saves space compared to bulky tank water heaters.

Key Factors to Consider When Choosing a Tankless Water Heater #
1. Choosing the Right Size (GPM – Gallons Per Minute) #
A tankless water heater’s capacity is measured in GPM (gallons per minute), indicating how much hot water it can deliver at a time. To choose the right size, calculate your household’s peak hot water demand.
| Fixture | Average GPM |
|---|---|
| Shower | 2.0 – 2.5 GPM |
| Kitchen Faucet | 1.5 GPM |
| Bathroom Faucet | 1.0 GPM |
| Dishwasher | 1.5 GPM |
| Washing Machine | 2.0 GPM |
Example: If you use a shower (2.5 GPM), a kitchen faucet (1.5 GPM), and a washing machine (2.0 GPM) simultaneously, you’ll need a tankless water heater with at least 6.0 GPM capacity.

2. Gas vs. Electric Tankless Water Heaters #
| Feature | Gas Tankless | Electric Tankless |
| Efficiency | Higher for large homes | Best for small homes |
| Operating Cost | Lower if gas prices are low | Higher due to electricity rates |
| Flow Rate (GPM) | Higher capacity | Lower capacity |
| Installation Cost | Higher upfront | Lower upfront |
- Gas tankless water heaters are ideal for larger households and provide a higher flow rate.
- Electric tankless water heaters are great for smaller homes or point-of-use applications.

3. Condensing vs. Non-Condensing Tankless Water Heaters #
- Condensing Models: Capture and reuse exhaust heat, making them more energy-efficient.
- Non-Condensing Models: Vent hot gases outside, requiring additional venting but often at a lower upfront cost.

4. Indoor vs. Outdoor Tankless Water Heaters #
- Indoor Units: Installed inside, requiring proper venting.
- Outdoor Units: Mounted outside, eliminating the need for venting but requiring protection in cold climates.
5. Energy Efficiency: Understanding UEF Ratings #
Tankless water heaters are rated using UEF (Uniform Energy Factor), which measures overall energy efficiency.
| UEF Rating | Efficiency Level |
| 0.65 – 0.80 | Standard Efficiency |
| 0.81 – 0.90 | High Efficiency |
| 0.91+ | Ultra-High Efficiency |
A higher UEF rating means better efficiency and lower energy costs.
