Considering Replacing A Hot Water Heater
A little while ago I talked about how my hot water heater was old and I didn’t know when the bad boy was going to go out. Perhaps it would go this year, perhaps next year, or perhaps after I’ve sold the home. That’s when someone suggested that I preempt the water heater and replace it early so I wouldn’t have to deal with the headaches. While I’m not ready to replace it just yet, I did begin researching my options so in case it does go, say tomorrow, I’m prepared for it.
Cost?
I called up BGE and they gave me a quote of $755 for installation of a Rheem 50-gallon electric water heater with a 12 year warranty. It’s only $655 for the same heater and a 8 year warranty, $605 for a 6 year warranty. Comparatively, the water heater itself sells retail for $249.99 for the 6 year warranty version ($349.99 for the 9 year warranty). $355 for installation on the six year warranty version? Seems a little pricey.
Why Should I Replace Early?
To answer those who would say replacing a hot water heater early would be somewhat of a waste, I think that in this case it’s not that bad of a decision because of the possible consequences. At best, we are without hot water for a couple days until someone can come out to repair or replace it. At worst, one of the metal fittings (or something else) bursts, flooding my basement with water. The worst is pretty bad because we just installed carpeting outside the undeveloped room that houses the heater, preempting a burst like that would be good if I could see the future.
Another case for replacing is that newer water heater models are more energy efficient than older models. I read off the Energy Star label that the unit takes about 6450 kWh of power a year, which costs $129 at 2 cents a kWh (I had to throw that in there because that’s what the label said!). We pay approximately 10 cents per kWh so our annual cost to keep that baby running is $645. The estimated annual operating cost of the 50 gallon Rheem electric water heater, according to the Rheem brochure, is a little lower at $402. I could drill down and get an estimated kWh figure (maybe I was too lazy) but based on the brochure and the EnergyStar label on my water heater, it appears the difference is approximately $243. That means that the replacement would pay for itself in under three years of use.
Tankless Water Heaters
A tankless water heater would’ve been a great option if it were available for us via BG&E (they only do gas tankless). Tankless water heaters are generally more expensive fixed/up-front but have lower operating costs since they have to keep a huge container of water hot for instant use. I didn’t do much research into this area, and I may in the future, because BG&E didn’t offer it. Electric tankless water heaters do exist though, so if you have experience with them or have done the analysis yourself, please do share because I’d be very interested to see it.
