Tankless Water Heater Stopped Working in Apex Home
The Problem
An Apex homeowner was without hot water because the controller for their tankless water heater was not registering.
What We Found
Nick found that the tankless water heater was nearly 20 years old and needed replacement rather than repair.
The Fix
Nick provided estimates and proceeded to replace the old unit with a Rinnai RXP199IN tankless water heater, which includes recirculation capabilities and a pre-scale filter. Chris installed the new unit, set the temperature to 120°F, and verified proper circulation. They checked all gas and water connections for leaks.
The Result
The new tankless water heater functioned properly, providing the homeowner with reliable hot water.
Pro Tip
A tankless water heater controller that doesn’t register often indicates a unit nearing the end of its life. Consider replacing it before it fails completely to avoid unexpected cold showers.

Efficient Water Heater Maintenance in Apex
The Problem
The homeowner needed a routine maintenance service for their tankless water heater and a replacement for a bathroom sink pop-up assembly.
What We Found
Upon arrival, it was confirmed that the left side master bathroom sink pop-up assembly needed replacement and the tankless water heater required flushing.
The Fix
Nick and Bernard replaced the left side master bathroom sink pop-up assembly with a new flat black model. They also performed a thorough flush of the tankless water heater to ensure optimal performance. Both tasks were completed efficiently, and the systems were tested to confirm proper functionality.
The Result
The homeowner's bathroom sink and tankless water heater were both functioning perfectly after the service.
Pro Tip
This is exactly the kind of issue a seasonal tune-up catches before it becomes an emergency. Our Comfort Club members get two precision tune-ups per year, priority scheduling, and no diagnostic fees — most members save more than the cost of membership in their first year.

Why Quality Water Heater Installation Matters in Apex
Summer Heat Stress
Apex's hot, humid summers with temperatures regularly exceeding 90°F put extra strain on AC systems, requiring more frequent maintenance to handle constant use and moisture.
Seasonal Demands
The Triangle's seasonal temperature swings mean HVAC systems must efficiently handle both heating in winter and cooling in summer, with proper tune-ups before each season.
Humidity Management
High humidity levels in Apex cause condensation issues and can lead to mold growth in ductwork if systems aren't properly maintained and sized.
Local Compliance
Local building codes and HOA requirements in Apex neighborhoods require specific permits for HVAC installations and replacements to ensure compliance.

Frequently Asked Questions About Water Heater Installation in Apex
Answered by our licensed technicians serving Apex
How long does a water heater installation take?
A standard tank-to-tank replacement typically takes 2 to 3 hours. If we need to upgrade the gas line, modify venting, or switch from electric to gas (or vice versa), the project may take 4 to 6 hours. We provide a time estimate before starting.
Should I get a gas or electric water heater?
It depends on your home's utility infrastructure and your priorities. Gas heaters have faster recovery rates and lower operating costs in most Triangle-area rate structures. Electric models are simpler to install and maintain. Hybrid heat pump electrics offer the lowest operating costs overall but need space and ambient warmth to perform optimally.
What size water heater does my family need?
For a household of 2 to 3 people, a 40-gallon tank is typically sufficient. Families of 4 to 5 should consider 50 gallons, and larger households may need 65 to 80 gallons or a tankless system. We base our recommendation on fixture count and peak usage patterns, not just family size.
Do I need an expansion tank with my new water heater?
Yes. North Carolina plumbing code requires a thermal expansion tank on any closed plumbing system — which includes most homes with a backflow preventer or pressure-reducing valve on the main water line. We include expansion tank installation as a standard part of every water heater replacement.
