Water heater recs please

[4570Man]

If you have a water recirculating pump like I do, tankless don’t work without some juryrigging a small standby tank or some such nonesence. I have twin 40 gal direct vents that are 10 years old, have replaced anode 2 times. Have another set sitting in WH room. I’m thinking about getting another pair of them and storing them because I don’t know what nanny state will do in near future with propane water heaters.i don’t want heat pump or elect units. Ive been called out to too many heat pump water heater failures over the years. And while elect units are ok, my standby isn’t large enough to add two elect water heaters to it.

I’ve installed tankless gas water heaters on new construction jobs that have factory supplied recirculating pumps. I like electric water heaters for the main reason they don’t require ugly vent pipes. They’re cheaper as well. The downside is they’re not easy to operate in a power outage.

A tanked gas heater will continue working without electricity.

We have one and I love it. It's an AO Smith that I bought at Lowe's and installed with my brother's help.

I’m not that sold on tankless water heaters. Electric ones are garbage. They strain a regular 200 amp service for the first problem. Putting that aside they struggle to produce hot water. Gas ones do produce plenty of hot water but the upfront cost is high. The heater itself cost nearly 3x what a regular 40 gallon water heater cost. The plumber also charges a good bit extra. If you have a lot of people in the house maybe it would be worth it but a 40 gallon heater should provide plenty of water for at least 4 people. If that’s not working you could piggyback 2 of them and still be cheaper than a tankless. My last complaint with the tankless is they require electricity to work. A tanked gas heater will continue working without electricity. I’m really not sold on the energy saving aspect.

All new tanked water heaters also require electricity to operate, just like gas furnaces. There are no pilot light heaters or furnaces sold today. They are all electric ignition.

FWIW, our tankless propane water heater doesn't require any grid power. It uses C batteries to make the spark. It's not rated for indoor use, but for folks who aren't constrained by the need/desire to do things conventionally, it works great. All the hot water we could ever want for $160.

I’m not convinced that’s true. I admit it’s been a long time since I’ve dealt with a tanked gas unit. I’ve not used them on any of my construction jobs. The ugly vent stack being the leading reason. But this is the cheapest gas water heater on the lowes website. This sheet doesn’t show any electric supply. I looked through the install manual and I didn’t see any mention of adding a power supply either.

Same. I've installed maybe half a dozen or so tanked gas water heaters. None had electrical connections. There may be some that do, but it's definitely not all of them.

When we did our installation recently, our plumber told us that the new units were all electric start. Maybe there are still a few pilot models, but they aren’t common.

My Bosch Tankless is 3 phase 380v at the cabin… very compact and no water heater tax on the property tax bill… yes a tax is collected on the size of the tank.

It’s not perfect but I have it dialed in and it’s got 33 years of vacation use on it.

Propane or natural gas gas is a problem whereas most everyone in the area has heating oil fired hot water…

Was not going to do all that is required to put in heating oil storage and boiler, etc.

All I’m finding is the $88 dollar natural gas 30 gallon water heaters of 30 years ago are now in the $750-$800 range to meet California low nox and sealed combustion and circuit board controlled.

My gas water heater of choice is Bradford White… before is was always Hoyt and loved the ones with lifetime copper tank but Hoyt is no more.

I am going to reconsider the tankless.

I did not mention this as we had the advantage of doing new construction. But I will chime in if this is of any additional help.

We built a residence with garage on one side and two master suites and bedrooms on the other. I wanted one tankless at the bedrooms, one tankless near the garage.

Plumber said: don't do that. Put them both together in the same location. Have them fire "in series" (if needed) to meet demand, and build a recirculation loop under the house. Whaaattt? This seemed to defeat the economy of tankless.

After a spirited discussion, I finally relented and said: "you are the expert, do it your recommended way."

My system works really well and I am happy with it. Only a very short lag to get hot water because it only comes from the recirc loop. Due to our limited demand, most of the time, I don't think I have ever seen both units fire at the same time to keep up with demand. But it could be possible with a houseful of guests. Maybe overkill but our master suites are over 100 ft from the tankless units.

As I said, maybe not applicable to an existing setup but thought I would contribute what I know ....
