Tankless Water Heater FAQ

How does a tankless water heater work?

Tankless water heaters heat your hot water as you need it. They heat it very quickly, so there’s usually not much of a wait for the water to get to you. This separates them from conventional heaters, which heat the water and then store it until you need it.

Are tankless water heaters worth it?

The right water heater for you will depend on the specifics of your situation. This includes things like how much hot water you need, how much hot water you use at once, and what your plumbing setup looks like. Many homeowners find that tankless water heaters are well worth any investment involved in installing them.

What are the most common problems with tankless water heaters?

Tankless water heaters can experience a wide variety of problems. These range from not producing enough hot water to leaking to experiencing water temperature fluctuation. Our team can address any of these issues and help you get your water heater working well again.

Can you run out of hot water with a tankless water heater?

If your tankless water heater cannot heat water as fast as you need it, then you may run out of hot water. In these situations, we usually recommend installing more than one water heater so you always have the functionality you need.

How long do tankless water heaters last compared to traditional models?

Tankless water heaters typically last 15-20 years or more with proper maintenance, substantially longer than the 8-12 year average lifespan of traditional tank models in Houston’s water conditions. This extended lifespan helps offset the higher initial installation cost. Luke’s Plumbing & Air Conditioning recommends annual maintenance to descale the heat exchanger and check system operations, which can further extend your tankless unit’s life by preventing mineral buildup that’s common with Houston’s moderately hard water.

What size tankless water heater do I need for my Houston home?

Sizing depends on your household’s peak hot water demand rather than home size. For most Houston families, you’ll need a unit that can handle multiple simultaneous uses—like running a shower while the dishwasher operates. We calculate this based on: 1) the temperature rise needed (difference between groundwater temperature and desired output), 2) maximum flow rate requirements (measured in gallons per minute), and 3) fuel type availability. Luke’s Plumbing & Air Conditioning can perform this calculation to ensure you get a properly sized system that provides adequate hot water without unnecessary expense.
