Hi Guys
this is a borderline finance question since the goal is to save money in the long run by being efficient.

We are looking to replace the electric water heater for our new condo.

we were looking into Tankless but we dont have enough circuits (100 Amp only) to support it. Also the hybrid ones seemed like a good option but we dont have enough space to install it.

So the only option is to use a electric water heater. we dont have gas in the condo , its all electric

i was wondering if you guys had any options what i could look at ? some specifications i was looking at is

- 40 gallon capacity since its just the 2 of us

- something that is very efficient, maybe even has a setting to turn the temp down when we are not at home almost 12 hrs a day

- i was told there are water heaters that sense a leak and turn the valve off automatically to avoid a huge mess

can you guys please help me out with a few recommendations i could look at ?

I plan on getting quotes from local plumbers and also from amazon local services. Has anyone had any experience using amazon services to find a plumber ?

thanks
S

If it's just two of you, a 40 gallon tank is probably too big. You could look at a 30 or even 25 gallon tank, which should be even more efficient. However, keep in mind the size of the condo, as it pertains to resale, because if you've got a 3 BR 2 BA condo, a 25 gallon tank probably won't cut it for different owners.

Most tank water heaters nowadays are pretty well insulated, so don't lose a whole lot of heat throughout the day. All heaters do have a temperature control switch, so you could turn it down each morning and back up when you get back home. You'll have to wait for the water to heat back up before using it though (e.g., to cook). If you plan on doing this, look at the recovery rate and / or the first hour rating. I think this is probably overkill, though.

Not sure they may actual heaters with leak sensors in them, but there are a bunch of home automation sensors that do that. Code also requires the water heater to be installed in a drain pan, so that should take care of small to moderate leaks anyway.

I installed a Whirlpool a couple years ago, and it was pretty straightforward. Basic tank water heater, and so far so good. The warranty length will also affect the price of the heater. With proper upkeep, any decent tank should last 10+ years, so I'd stick with the shorter warranties to save money (I went with the 6 year warranty)

Thanks mmathis, i appreciate your reply. I looked at 30 gal tank but the cost difference between the 30 and 40 is not too much and i usually have family visiting during the summer and fall season. The condo is 2 Bed 1 Bath, so not too big.

I looked at the rheem performance and performance plus. i wonder if i should go for the plus series which has an extra 1 year labor and an extra 3 year warranty over the performance series. It costs $50 more.
i do plan on staying in the condo for atleast the next 6 years.

Thanks

@narnaie .. thank you for pointing me to the forum. I atleast have it boiled down to either the AO Smith ones or the Rheem performance ones. next step would be to get the quotes and get the installation done.

@Komondow - thanks for the product, it definitely seems like it could save some money over the long run and i will definitely look into this. its just the DIY things make me nervous since i havent done much earlier.. but have to start sometime right !

Thanks

who you get to install the heater can add the timer.
You cant just turn the water heater t-stat up and down as you want.. they aren't made for that

for those that hate spelling mistakes www.walmarts.comCool

bulb save money by checking your insurance every 2 years (and not every 20)

You could buy a heat pump water heater, uses about about half the electricity of a conventional electric water heater. (no rewiring involved), also dehumidifies your house a bit in the summer

40 gallon electric is the bare minimum size to consider. Get something simple but with a 9-12 year warranty because those tend to have better insulation and corrosion protection than the 6-year units. DIY installation isn't that hard if you use CPVC plastic pipe and CPVC pipe glue. Notice I said CPVC, not PVC, which is illegal for hot water. I wouldn't use PVC even for the cold water feed, even if that's allowed, because there are circumstances where the cold inlet pipe can get very hot. Do NOT use PVC glue on CPVC; it won't dissolve it nearly enough to give watertight joints. All fittings must be CPVC, too, especially because they're sized differently so they can't be mixed up with CPVC pipe. PEX pipe is also good but requires a special crimping tool. Remember to install heat traps and insulation from the heater and past the heat traps. Heat traps (either 1-way valves or loops that go up and down at least 8") will stop the heat leaks almost completely; with out them the pipes will feel warm even 5-10 feet from the heater. A timer will make a lot of sense if your electricity is billed by time of day or by peak demand.

Heat pump water heaters will consume 1/2 to 1/3 as much power but are much more expensive and not nearly as reliable. I don't know which brands are the most trustworthy.

I have serious doubts as to whether timers really get you much whatsoever. IF you only wanted to heat your water say during off peak times than I could see it making sense however the tanks they have these days are highly efficient. I've gone away for 3 weeks and turned my hot water heater off and come home to piping hot water.

As others have said those heatpumps that come up on here seem like a good alternative but I don't think they're as reliable. Still over 5 years you'll probably come out ahead but who knows.
