Points to Consider When Replacing Your Water Heater:
- Energy Efficiency: Modern energy efficient water heaters use advanced technology to reduce energy costs.
- Tank vs. Tankless: Choose based on space, water demand, and long-term savings.
- Installation Cost: Transparent estimates for water heater installation cost or tankless water heater cost.
- Maintenance Requirements: Regular hot water heater maintenance keeps your system running smoothly.
When to Replace Your Water Heater Versus Repair It
Knowing whether to repair or replace your water heater can save you money and prevent unexpected breakdowns. Consider replacement if:
- Your unit is over 10-12 years old
- Repairs are frequent or costly
- Energy efficiency is low
- Leaks or corrosion are present
For less serious issues, a professional water heater tune-up, hot water heater maintenance, or tankless water heater maintenance can restore functionality and extend the system’s life.
Tankless Water Heater Repair & Installation
Tankless systems are increasingly popular for their energy efficiency and on-demand hot water. We provide:
- Tankless Water Heater Installation: Professionally installed to maximize performance.
- Tankless Water Heater Repair & Maintenance: Preventive and corrective services to avoid costly breakdowns.
- Tankless Water Heater Tune-Up: Annual inspections to ensure optimal operation.
Investing in a tankless system can save you money in the long run. It also gives you a more reliable hot water supply for your home. Regular tankless water heater maintenance ensures these systems perform efficiently for years to come.
Don't Wait for a Complete Failure
Most people wait for their existing water heater to fail completely before they replace it with a new one simply because they are unaware of the signs of a gradually failing unit. It is crucial that you know when your water heater is on its last leg to avoid damage and disruption.
Signs Your Water Heater Is Failing
Be alert for these indicators that clearly show your existing unit is about to fail:
- Rusty water
- Rumbling sounds
- The heater has sprung a leak
- Hot showers are not as hot anymore
- Having to wait for hot water when taking a shower or using any fixtures in your home
- Temperature problems
- Not enough hot water
- Noises in the tank
- Sediment buildup
- Slow recovery time
If you discover any of these signs, you should start exploring your options to identify a new water heater that best suits your needs.
Local Code Requirements
You'll find many accessories available for your new water heater. Some are required by local codes; others are just good ideas. Plumbing codes vary, so check with your local inspector.
- Gas Shutoff Valve - All codes require a gas valve near the water heater.
- Drip Leg - Any dust or grit in the gas line falls into this short section of pipe before it can reach the water heater's control valve. The required length of the drip leg varies.
- Isolation Valve - All codes require a valve on the cold-water line. Though not required by codes, a second valve on the hotline makes future water heater replacement easier.
- Overflow Pan - Most plumbing codes require a pan and drainpipe in locations where a leak can cause damage. But installing a drain pan is a good idea for any location.
- Expansion Tank - Some codes require an expansion tank to absorb the pressure created when heated water expands.
- Blow Tube - The T&P valve releases pressure, and a "blow tube" directs the scalding hot water toward the floor. The required distance between the blow tube and floor is usually 18 inches or less.
- Water Heater Bonding - New Jersey building codes require a bonding wire be installed between the cold/hot pipes and the gas line. The majority of local codes don't require the bonding wires, but they do serve a purpose. According to experts, bonding wires may actually extend the life of the water heater by diverting electrolysis from the anode rod and tank-even on electric models. So, whether or not your local code calls for the bonding wire, you may want to install one to get the most useful life out of your unit.

Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too.

Professional & Friendly
Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.
