Repair or Replace? Knowing the Difference Saves You Money

Not every water heater problem means it needs to be replaced, sometimes it just needs a professional to check it out and solve the problem. Before starting any work, we always assess the issue and give you a clear diagnosis of what’s going on. 

Signs Your Water Heater May Need a Repair

  • Inconsistent water pressure during a shower or when using sinks
  • Rumbling or banging sounds coming from the system
  • The ignitor won't stay lit
  • Minor drips coming from parts of the water heater
  • Water taking longer than usual to heat up
  • Water is rust colored

Signs Replacement May Be the Better Call

  • The unit is 10–15 years old and is constantly having problems
  • Tank leaking water
  • A repair would cost more than half the price of a replacement
  • Increasing energy bills for no apparent reason 
  • The unit can no longer produce the amount of hot water you need

What Parts of a Water Heater Commonly Need to be Replaced

Thermostat Replacement

This controls the temperature of the water coming from the water heater. If it’s not working properly, your water may be too hot, too cold, or an inconsistent temperature. 

Pilot Light and Igniter

If the igniter won’t stay lit or even spark, the heater never fires which means no hot water coming from the system.

Sediment Flushing  

This requires draining any mineral buildup that is settled on the bottom of the tank. This usually causes some sort of rumbling coming from the system, and if left alone, it could decrease the amount of time you can use the water heater. 

Heating Element Replacement

Electric water heaters have two elements that heat up the water. If the lower element burns out, you will receive a little hot water before it runs cold. If the upper element burns out, you will get no hot water coming from the system. 

Gas Valve Replacement

Controls the amount of gas that gets to the burner. If this isn’t working, gas may not be able to flow to the burner properly, and water won’t be able to heat up. 

Tank vs. Tankless Water Heaters

  • Normally cheaper upfront cost 
  • Simple replacement in the future when necessary 
  • Lower effort in terms of maintenance 
  • Cheaper repairs 
  • It’s able to handle demand from multiple things at once well 

Pros of a Tank Water Heater

  • Usually lasts 8-12 years which is shorter than tankless water heaters 
  • You will run out when there’s no more water in the tank 
  • Takes up more space 
  • If the tank ever breaks, 40-80 gallons of water can go everywhere

Cons of a Tank Water Heater

  • Typically lasts at least 15-20 years with annual descaling 
  • Doesn’t run out of water 
  • Frees up space 
  • No tank that could potentially flood your home

Pros of a Tankless Water Heater

  • Typically is 2-3x more expensive upfront due to more expensive system and potential gas line and venting upgrades 
  • If water is being used at multiple points in the house, depending on the flow ability of your tankless system, the water temperature might not be very hot 
  • Annual maintenance, at the very least, is mandatory to remove mineral buildup and keep the unit working

Cons of a Tankless Water Heater

How H2O Handles Water Heater Installations

Step 1 — Assessment and Getting Necessary Permits

We start by going through your current system setup and figuring out what will work best for you in the future. An undersized unit will not meet your needs, and an oversized unit is just a waste of money, so we’ll do our best to find out what’s right for you. Then, if necessary, we will pull the proper permits and ensure we’re meeting all state and local codes. 

Step 2 — Removal and Installation

The existing water heater is shut down, disconnected, and disposed of by us so you don’t have to worry about it. Then, we will handle the entire installation process and test it to make sure it’s working properly. 

Step 3 — Test, Confirm, and Walk-Through

Once we get the unit up and running, we will test the hot water at multiple points in your home to ensure you’re getting hot water everywhere you should be. Then, we will walk you through your new water heater, give you recommendations for the future, and answer any questions you may have! 

We make this process as simple and easy as possible for you. If there are any accommodations you’d like to request before the installation, feel free to let us know and we’ll do our best to make it work.
