Tankless Water Heater Worth It Florida

If you’re in the market for a new water heater, you’re probably wondering whether a tankless water heater is worth the cost to install in your Florida home. We hate to give you a vague answer, but it depends!

Tankless water heaters ($2,800–$4,800) are more expensive than tank water heaters ($900–$1,500), but they can be worth it depending on the following factors:

  • Your household’s hot water demand
  • How much you value long-term savings
  • The amount of space you have

Below, we’ll dive into each of these in more detail, so you can determine if a tankless water heater is worth it for your Florida home.

Factor #1: Hot water demand

Homeowners tend to prefer tankless water heaters because they provide instant and “never-ending” hot water.

What exactly does that mean?

It means you don’t have to worry about having hot water after someone has taken a 30-minute shower or the dishwasher just ran. If you wanted to run a hot water faucet or showerhead for 3 hours, you’d have hot water the entire time. With a tank water heater, you’d run out of hot water and have to wait for another tank of water to be heated.

However, even though tankless water heaters provide “never-ending” hot water, it’s not unlimited.

What do we mean by that?

Tankless water heaters are limited by their flow rate. Flow rate measures how many gallons of hot water a tankless unit can provide in one minute.

Every hot-water appliance in your home also has a flow rate, measuring how much hot water the appliance consumes in one minute. If you run too many hot-water appliances at once, the total flow rate of these appliances may be greater than the tankless unit's flow rate, meaning there wouldn't be enough hot water to go around.

Because of this limitation, tankless water heaters are best for smaller homes and households that don’t use a ton of water at one time. However, there is a way around this. If you have hot water appliances that consume a lot of hot water (like a dishwasher or washing machine), you can install multiple point-of-use tankless water heaters in your home as well as one main tankless water heater.

These point-of-use water heaters will be dedicated to supplying hot water to one appliance, so you can run multiple hot water appliances at once.

Factor #2: Value of long-term savings

Even though tankless water heaters cost more upfront, they usually result in long-term savings compared to tank water heaters. Why? Tankless water heaters...

  1. Are more efficient than tank water heaters- As we mentioned above, tankless water heaters heat water on demand rather than keeping a tank of water continuously warm, as tank water heaters do. The result is that tankless water heaters are much more efficient than tank water heaters. According to Energy.gov, tank water heaters can be 24%–34% more energy-efficient than tank water heaters for homes that use 41 gallons or less of hot water daily. Even if your home uses more water (up to 86 gallons per day), a tankless water heater can still be more efficient, by about 8%–14%.
  2. Have a longer lifespan- On average, tank water heaters last up to 20 years, while tank water heaters usually only last 10–15 years. This means that you’ll usually get 5–10 more years out of tankless water heater, which makes the upfront investment worth it.

Factor #3: Space

Unlike tank water heaters which physically store 20–100 gallons of water, tankless water heaters don’t hold any water, so they’re very small.

For you, this means that instead of filling an entire closet with a water heater, you can fit a tankless heater in a cabinet or may even be able to mount it on an outside wall in some cases.
