Cold Shower! Replacing a Water Heater (includes expected $ saved)

There is almost no worse feeling than taking a shower with no hot water!  I recently had this happen to me on a Saturday.  I went to check on the water heater and noticed water coming out of the top access panel (not good!).   That is not supposed to happen!   I had previously changed out the bottom heating element for the unit, but this was obviously a bigger issue.  After 16 years of use, it was due to be replaced.

I did some research to on the size of the unit and possible costs.  Here are some of the findings:

  • Cost range for a 50 gallon electric water heater:  $400 – $600
  • Average install cost (from  $475 national; approx $300 local
  • Total expected cost (with 10% cushion for parts/overages) :  $770 – $900

After doing this initial research, I explored the options available:

Option 1:  Hire a plumbing company to perform the work.

I received a quote from a local plumbing company that had done work fore me before, and they came back with a quote of $1200.  That was above what I was expecting, but it would also be the “easiest” as they recommended a specific unit so I wouldn’t have to think/worry about the unit to choose.

Option 2:  Buy the unit and installation from a big box store.

When I had the issue with the heating element before, I considered replacing the unit.  The initial install price seemed reasonable, but it quickly increased when “options” were included such as installing on a stand (which my current unit is on.  I attempted to call the toll-free number to get a new quote, but as I called on a Saturday, I was routed to a call center and they told me that installation was not available in my area.  I know this was wrong as I had a previous call and quote and there were signs in the local store saying installation was available.

Option 3:  Buy the unit and install it myself.

I don’t mind performing work myself to get experience and also saving money.  When I work on something I haven’t done before, I worry that I might get in over my head.  To better understand what it takes to perform an install, I watched some youtube videos and studied my existing unit.

Decision:  Buy unit and do it myself.

I ultimately decided to do it myself as I didn’t want to wait until a weekday to  have my hot shower and also didn’t want to pay the extra for a plumbing company or a contractor from the big box store to do the work.  I decided to get a unit with a 12 year warranty and picked it up at the store.

First Step:  Disconnect water, drain tank, and remove the old unit

Here is a picture of the old unit, being drained with a hose connected to the unit.  I drained the unit outside in the grass.

Next:  Unhook the plumbing and electrical from the old unit.

Next, remove old unit and put new unit in place:

Finally, Hook-up the plumbing and electrical, and power-up!

Yes, I was able to have a hot shower again!  Monday morning was a good start to the week as I realized while taking a hot shower that if I wouldn’t have done the install, I would have started my week with a cold shower!

Cost Savings: 

Let’s take a look at the Energy Guide annual electricity amounts for both the old and new unit:

Old water heater
New water heater

From the sticker, you see the new unit should cost $420/yr @ 12 cents/kWh vs. $419 @ 8 cents/kwh for the old unit.

Looking at the yearly energy usage on the energy guide sticker:

  • New unit:  3493 kWh per year
  • Old unit:  4992 kWh per year

This is a delta of 1,499 kWh/yr of electricity usage.  On average, the current electrical rate here is 10 cents/kWh.  The result is a savings of around $150/yr in electricity costs with the new unit vs. the old! 

Based on the cost savings, I should have replaced the water heater several years ago!

Do you have an old water heater?  Have experiences similar?

    1. The toughest part is getting started, trying to figure out how to do it and the tools needed. Once I started, it was intuitive. Thanks for the comment!
