Best Tankless Water Heater

Tankless water heaters are becoming increasingly popular as homeowners look for ways to save energy and money. Here are some of the benefits of a tankless water heater compared to a traditional tank water heater:


  • Endless hot water: Tankless water heaters provide hot water on demand, so you’ll never run out of hot water in the middle of a shower or when you’re washing dishes.
  • Energy efficiency: Tankless water heaters are much more energy-efficient than traditional tank water heaters. They only heat water when you need it, so you’re not wasting energy heating water that’s just sitting in a tank.
  • Space saving: Tankless water heaters are much smaller than traditional tank water heaters, so they can be installed in tight spaces or where there’s limited floor space.
  • Longer lifespan: Tankless water heaters have a longer lifespan than traditional tank water heaters. They can last for up to 20 years, while traditional tank water heaters typically last for around 10 years.
  • Reduced maintenance: Tankless water heaters require less maintenance than traditional tank water heaters. They don’t need to be drained or flushed regularly, and they don’t have a sacrificial anode that needs to be replaced.

If you’re looking for a new water heater, a tankless water heater is a great option. They offer a number of benefits over traditional tank water heaters, including endless hot water, energy efficiency, space saving, longer lifespan, and reduced maintenance.


Additional factors to consider:

  • Fuel type: Electric or gas (propane)? Consider availability, cost, and efficiency.
  • Flow rate: How much hot water do you need simultaneously?
  • Temperature rise: Desired maximum hot water temperature.
  • Installation: Professional installation is recommended for most models.
  • Warranty: Look for a good warranty for peace of mind.


Remember, this is just a starting point. Research each option thoroughly and consider consulting a qualified plumber to determine the best fit for your needs.

Frequently Asked Questions

The most common issue with tankless water heaters is often related to inadequate maintenance, leading to mineral buildup and scaling within the unit. This buildup can restrict water flow, decrease efficiency, and eventually cause the heater to malfunction. Additionally, improper installation or sizing can lead to performance issues such as inconsistent water temperature or frequent shutdowns. Regular maintenance, proper installation, and occasional descaling can help mitigate these problems and ensure optimal performance of tankless water heaters.

For a family of four, a tankless water heater with a flow rate of at least 8 gallons per minute (GPM) is recommended to ensure an adequate supply of hot water for simultaneous usage. This size can accommodate multiple showers, appliances, and faucets running at the same time without a significant drop in water temperature. However, factors such as the climate, desired water temperature, and usage patterns should also be considered when determining the appropriate size for your household. Consulting with a professional plumber or installer can help ensure you select the right size tankless water heater for your specific needs.

With tankless water heaters, the likelihood of running out of hot water is significantly reduced compared to traditional tank-based systems. Tankless heaters provide hot water on demand, heating water as it flows through the unit, eliminating the need to wait for a tank to refill and reheat. However, the capacity of a tankless water heater depends on factors like the unit’s size and the water flow rate, so it’s essential to choose an appropriately sized unit for your household’s needs to avoid potential issues of insufficient hot water during peak usage times.

The life expectancy of a tankless water heater typically ranges from 15 to 20 years with proper maintenance and usage. Factors such as water quality, installation quality, and frequency of use can influence its lifespan. Regular maintenance, including descaling and flushing, can prolong its efficiency and durability. Additionally, choosing a reputable brand and ensuring professional installation can contribute to its longevity. While initial investment may be higher than traditional water heaters, the longer lifespan often offsets the cost over time.

The cost of converting a water heater to tankless depends on various factors such as the type of tankless unit chosen, installation complexity, and any additional modifications required to existing plumbing and gas lines. Typically, the cost includes the price of the tankless water heater itself, installation labor charges, any necessary permits, and potential additional expenses for adjustments to accommodate the new system. Additionally, factors like the location and accessibility of the installation site may influence the overall cost. It’s advisable to obtain quotes from reputable professionals to get a precise estimate tailored to individual circumstances.
