Rinnai tankless water heater — West Palm Beach, FL
Last updated: September 24, 2026
What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
A Rinnai tankless unit heats water only when you turn on the tap, rather than keeping a large tank hot all day. This is a great choice if your household uses a lot of hot water simultaneously or if you want to save space in your utility closet. Because they provide an endless supply of hot water, you won't run out during long showers. We can help you determine if your current gas lines and venting meet the requirements for a Rinnai installation.
Frequently asked in West Palm Beach
What is the installation cost for a tankless hot water heater?
How do you repair a Rinnai tankless water heater?
Repairing a Rinnai tankless water heater often involves diagnosing issues like error codes displayed on the unit or inconsistent hot water. Common repairs might include cleaning or replacing the heat exchanger, servicing the igniter, or fixing water flow sensors. It’s crucial to have a qualified technician handle these repairs to ensure safety and proper function.
What are the benefits of a Navien tankless water heater?
Navien tankless water heaters offer significant energy efficiency, heating water on demand and reducing standby heat loss. They provide a continuous supply of hot water, preventing the 'cold shower' surprise. Many models offer smart features for remote monitoring and control. They are also compact, saving valuable space compared to traditional tank units.
What is a water heater anode rod and what does it do?
A water heater anode rod is a metal rod, typically made of magnesium, aluminum, or zinc, installed inside your water heater tank. Its purpose is to corrode instead of your tank. It acts as a sacrificial component, attracting corrosive elements in the water and preventing them from attacking the tank lining. Replacing it regularly extends the tank's life.
What are the pros and cons of an electric hot water heater?
Electric hot water heaters are generally simpler in design and often less expensive to purchase than gas models. They don't require ventilation, offering more installation flexibility. However, they can be more expensive to operate due to electricity costs. They also may not heat water as quickly as gas units, which can be a consideration for large households.
What makes tankless water heaters energy efficient?
Tankless water heaters are energy efficient because they heat water only when you need it. Unlike traditional tank heaters that constantly keep a large volume of water hot, tankless units activate only when a hot water tap is turned on. This 'on-demand' heating significantly reduces standby energy losses, leading to lower utility bills and a smaller environmental footprint.
How often should I replace my water heater anode rod?
You should inspect your water heater anode rod every 1-3 years. Replacement is typically needed every 3-5 years, depending on water quality and usage. If the rod is significantly depleted (less than half its original thickness) or heavily corroded, it's time for a replacement. This simple maintenance is crucial for preventing tank failure.
