2. Endless hot water

There is no tank to run out of hot water, so two people can take showers at the same time. Or be washing clothes while someone is showering, without having to hurry to get out before it gets cold.

3. Lifespan

– the life span of standard tank water heaters is about 8-10 years. Whereas tankless water heaters can last twice as long, depending on water quality and maintenance.

– another pro of tankless water heaters is the savings of both energy and money you’ll save month-to-month. Tankless water heaters are so much more energy efficient and only heat water when necessary. No more spending money constantly heating 40+ gallons of water all day, everyday for no reason.

– when a traditional tank water heater leaks or bursts you can come home to find a flood floor. That can ruin floors, cause mold issues and cost thousands of dollars in damages. Tankless water heaters can leak but they won’t flood your home like a tank water heater can.

2. Hot Water Supply

This can be an issue, especially in terms of costs to upgrade gas lines. This is why tankless water heaters can become limited to the amount of hot water they can provide with high demand.

3. Maintenance

– another drawback of tankless water heaters is the maintenance. They can require much more than typical water heaters. Depending on your water quality the system may need to be flushed or descaled of minerals, etc. This can also increase the costs of owning one of these.
