Rinnai tankless water heater — High Point, NC
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 High Point
What are the pros and cons of an electric water heater?
Electric 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 happens when a water heater is leaking?
When a water heater is leaking, it means water is escaping from the tank or its connections. This can be due to a corroded tank, a faulty valve, or loose fittings. A leaking tank often indicates significant internal damage and typically requires replacement. Small leaks from pipes can sometimes be repaired, but it's essential to address any leak promptly to prevent further damage.
What is involved in hot water heater replacement?
Hot water heater replacement involves removing your old unit and installing a new one. This includes disconnecting the old heater, safely disposing of it, and installing the new unit according to code. It may involve plumbing adjustments, gas line connections, or electrical work, depending on the type of heater. A professional ensures the new heater is properly sized and installed.
What is involved in tankless water heater maintenance?
Regular maintenance for tankless water heaters is crucial for optimal performance and longevity. This typically includes descaling the unit to remove mineral buildup, especially in areas with hard water. Flushing the system annually helps prevent clogs and ensures efficient operation. Inspecting the vent and gas lines is also part of routine care.
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.
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.
