Looks like one, of our two, hot water systems may have finally died.

Both, I believe, are original for when the house was built 22 years ago and are electric units in my crawl space.

So, I think I will take this opportunity to go with whole house instant hot water system.

I now have natural gas, so I think that's the direction I'd like to go.

Also, I think an external unit would be preferable for the annual servicing.

So I'm looking for pro's and con's and recommendations from those of you who may have been down this path.

Thanks.
