Best Water Heater for Very Hard Well Water?

[inspectordan]

We are replacing our electric resistance water heaters on average every 3 or 4 years. Rheem Marathon? Heat Pump Water Heater? ....gas isn't an option since we're talking 55 units and venting and makeup air in these 3 story buildings would be a nightmare. TIA.

Google stainless steel water heater

Are they being replaced cause they start leaking, or due to excessive scale buildup. If water is that hard you should have a water softener and treatment system. Do the water heaters get flushed regularly to help remove scale buildup.

I inspected the property for the buyer who has it under contract. It looks like they're corroding and since Google tells me that the well water for this municipality is 22-23 grains then I have to assume it's also gobbing up the heating elements. There is a softening system in place but it doesn't look big enough for the number of units and the system does not appear to be properly maintained.

Unlikely to leak, but will the heating elements last any longer?

"Titanium elements with low watt density, longer element life' according to the product literature. At least this type of water heater (with it's 'lifetime' stainless steel tank) will be worth the time and effort it takes to drain the unit, replace the elements, and check/replace the anode rod. Right?

Thanks. Do you think the Ariston with SS tank would be preferable to the Rheem with it's non-metallic tank?

It doesn’t have an anode rod.

The elements will last just as long as any other element IMO.

I’d buy the stainless heater before I bought the Rheem. The parts on the Rheem are special.

The reviews on the stainless one arnt to good, especially if something goes wrong.

Water test? Do you have detailed info on what is in the 'hardness' of the water? I would solve the long-term problem first. I live on well water that is in that range with super high calcium.... just six weeks after moving in my house (before we had the softener installed) resulted in massive accumulation in fixtures and pipes. Proper water softener solved it.

That makes sense because most people don’t leave a review if they’re happy. I never leave good review…..only bad. Every brand has trouble just like every car dealership has a service department.
