water heater costs 40 vs. 50 gal archived

Oct 17, 2007 at 11:21am
We are replacing a 15 yr old 40 gal water heater and are considering a larger 50 gal. unit because it's only $50 more. Besides the benefits of having more hot water available, is there a significant difference in energy costs? The plumbing company said it wasn't much of a difference, but I want to make sure before making the switch. Thanks!
Go tankless!!

The newer water heaters are much better insulated so I imagine the extra energy costs (of maintaining another 10 gals of hot water) are relatively small.

There are some real drawbacks to tankless units from the brief research I did when we had to replace our water heater a couple of months ago (went for the 50, no regrets thus far.) Can't remember the details but it's worth reading the pros AND cons.

Is there a significant advantage to you of heating that extra 10 gallons of water every time? If you're really using close to 40 gallons of hot water in a short period of time, then you probably might as well go to 50.

Otherwise, any incremental cost is just throwing money away.

Oy people!!!!! the energy cost for a 50 gallon water heater is less than 300.00 a year! How much are you going to save by going with a 40? or a tankless for that matter? Fifty bucks?

Be comfortable and stop obsessing!

Thanks all. Plungy - that is exactly the info that I needed. 50 gal it is.

plungy,

Why get more than you need? No matter what it costs, it's wasted energy.

Unless you noticed a problem with your existing 40-gal running out of hot water regularly, there's no need to go for a 50-gal model.

Just wasteful.

We have a son who is spending the semester abroad, studying in Ghana. Much of the time he is there, housing is provided as a "home stay" with families who take the students in for a few weeks. About three weeks ago, one of his e-mails described how he had learned to bathe each morning using the equivalent of four or five cups of water.

I'm agnostic on larger water heaters (if you have a large family and a lot of laundry, it can be a big help), but the kinds of severe restrictions on water consumption already evident in several southern states, coupled with our son's observations from a country where water is personally acquired each morning, make it a bit harder than before to just super-size our lives. No one decision is so big, but taken together, maybe they are.

Yes of course JDM, and always shower with a friend!:bigsmile:
