If you’re in the market for a new water heater, you’ve probably stumbled upon tankless water heaters in your research. But what is a tankless water heater and how does it work? Gotelli Plumbing is here with all the details you need!
To put it simply, tankless water heaters heat up water instantly as it flows through the device, without storing water in a tank. You can use multiple units throughout the house, one large unit or one in conjunction with a traditional water heater. This design is growing in popularity and provides extensive benefits, and it could be perfect for your home.
If you think your home is a good fit for a tankless water heater, reach out to our team today!

The biggest benefit of a tankless water heater is the continuous and instantaneous flow of hot water. Instead of holding a set amount of hot water that runs out once used, tankless water heaters instantaneously heat the water as you need it, providing virtually unlimited hot water.
That means you can take all the long, hot showers you want without depriving other members of the household of hot water usage. But there are a number of additional benefits to going tankless. Tankless water heaters also:
When you install a tankless water heater, you’ll begin seeing the benefits immediately. You may be surprised when you see your first utility bill! Not to mention, lowering your gas, electric and water bills means you will also be doing your part for the environment.
We’re living in an age where even the most basic home devices, like refrigerators and lighting systems, are connected to your smart device. With so much of our homes being automated, it’s not too much of a surprise that some tankless water heater systems can connect to your smartphone. Units with Wi-Fi capabilities allow you to control the water temperature and monitor gas usage from your phone.
Some of these smart units can even tell you when something is wrong, so you can get repairs quickly. Now that’s a smart home!
Like all appliances, tankless water heaters are an investment. They do tend to cost more upfront than traditional water heaters but with good reason. Not only do they immediately start paying for themselves by lowering your energy and water bills, but they also last twice as long as traditional water heaters, paying for themselves and then some over time.
At Gotelli Plumbing, we believe in being honest and upfront with the costs of our various services, even if each quote is going to be different. Service costs vary by what needs to be done.
Installing a tankless water heater is definitely not for the inexperienced. Luckily, our technicians are highly trained and have experience working with water heaters of both tankless and traditional varieties. We’ll help you find the best model for your needs, and if anything ever goes wrong, we’ll help you with repairs.

Keep your new system running at its best with Grampa Gotelli’s Comfort Club, a yearly maintenance membership for Marin County homeowners.
Yes. Mineral scale builds up inside the heat exchanger and has to be flushed out, which most manufacturers call for annually. Skipping it hurts performance and can affect your warranty coverage. Our Comfort Club membership keeps this on schedule so you don’t have to track it.
Not on its own. Even gas-fired tankless units need electricity for the ignition, control board and venting fan, so they stop producing hot water when the power goes out.
More than swapping one unit for another. Tankless systems usually need a larger gas line, their own dedicated venting and an electrical connection, and the water lines often have to be rerouted to the new location. That’s why conversion quotes look different from a straight tank replacement — we walk the space before pricing it.
A properly sized unit handles normal household use without trouble. An undersized one shows it when a shower, dishwasher and laundry all run at the same time. Larger homes sometimes do better with two units, which is why sizing is the part worth getting right upfront.
