When to Replace Your Water Heater Versus Repair It

Water heaters are appliances that you use every day for many different purposes, from washing your dishes to showering. Your unit goes through an incredible amount of wear and tear over the years, and, over time, will inevitably need to be replaced. Our experienced plumbers can help you determine if your water heater is ready to be replaced and, if so, which type of unit is right for your home. Additionally, they can help to fix your water heater if that is all that is needed.

If your water heater is not working efficiently, you can have it repaired and extend its service life with regular maintenance depending on your make and the quality of the installation.

If a tripped circuit breaker or a blown fuse is not the cause of your water heater's failure, you can have it checked for the following:
  • Is the power connected?
  • Are sediments present?
  • Is the heating element functional?
  • Is the pilot light lit properly?
  • Is the gas burner clean?
  • Is your unit making hissing noises?
  • Are all of the fittings tight?
  • Is the pressure relief valve leaking?
If your water heater has surpassed the life expectancy suggested by the manufacturer, it is time to replace your unit.

Know What Resides in Your Water Heater

A water heater that is over 10 years old can have a buildup of sediment that is caused by city water quality and/or a deteriorating anode rod inside the water heater. When this happens, the water coming into your home can be contaminated, discolored, and will affect the overall cleanliness and taste of your home's water.

The Average Lifespan of Residential Water Heaters

The service life of any well-maintained residential water heater ranges from 8 to 10 years depending on the quality of water and the design of the unit. If your water heater is older than a decade, has a leaky base, and does not heat water as efficiently as before, it is probably time to install a new one.

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.

Points to Consider When Replacing Your Water Heater

When replacing your existing unit, you should consider upgrading to an energy-efficient unit.

Check the following factors to ensure that you make the right choice:
  • A heating capacity of at least 40 gallons
  • The number of gallons your heater can heat in one hour
  • The height and width of the heater to ensure that it fits the space you have
  • Check the energy-efficiency ratings of the unit you plan to purchase
  • The label on either side of your existing unit will reveal important information like the tank capacity, model, installation guidelines, serial number, wattage capacity, working pressure, and voltage. This information will serve as a guideline when searching for a similar unit or an upgraded version as well.

When you purchase a water heater from Guaranteed Service, you can be sure of:
  • Strict adherence to all safety regulations
  • Timely replacement of gas safety valves
  • Safe installation of both cold and hot water supply lines
  • Testing of water pressure, shut off valve, and water delivery rate
  • Installation of safety ground for protection against fire hazards
  • Disposal of the existing water heater

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.

Tankless Hot Water Heaters Versus Tank Storage Water Heaters

We've put together this comparison of storage water heaters vs. tankless water heaters to help homeowners and contractors decide what type of water heater is the best fit for you. We'll examine the pros and cons of tankless and traditional units so you can make an informed decision.

What Is a Tankless Water Heater?

Tankless water heaters, also known as on-demand water heaters, use high-powered burners to rapidly heat water as it runs through a heat exchanger and deliver it directly to your faucets or shower without storing it in a tank. Tankless water heaters are usually powered with electricity or gas. These types of water heaters were found to be 22% more energy-efficient on average than the gas-fired storage-tank models in tests conducted by Consumer Reports.

How Are "Traditional" Tank Storage Water Heaters Different?

Storage tank water heaters are commonly found in most homes. Their components are an insulated tank, typically holding 30-50 gallons of water, to heat and store the water until it's needed. A pipe emerges from the top to deliver hot water to its destination, kitchen, bathroom, or other sinks.

Typically, there are storage tank water heaters that use either natural gas or electricity for their fuel. Natural gas storage tank units use almost 50% less energy, costing less to operate, than the electric variety. However, they cost a bit more to install than electric models. They also feature a temperature and pressure-release valve that opens when either temperature or pressure exceeds preset levels. We provide gas, electric, and tankless water heater service, throughout New Jersey.

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.
