Twice a year, like clockwork some of us here in the US and around the world have to reset our time keeping mechanisms to keep up with the insanity that is Daylight Savings Time. Similarly, twice a year some of us have to jack up or jack down the temperature of our hot water heaters to keep our shower water control valves in their "sweet spot". Additionally and probably not germane to my question, when I lower the setting on the hot water heater in the summer months, this also causes the dishwasher to have to electrically heat the water it receives which I would think is a net energy use increase over simply getting hot enough water from the water heater itself.

Yes, I know this is probably a first-world problem, but has anybody designed a hot water dispensing system that automatically senses the temperature of the incoming cold water supply and "automagically" does something to compensate for this phenomenon?
A thermostatic valve can compensate but not a tank water heater if I’m still understanding you correctly.

A thermostatic valve automatically adjusts hot and cold to a specific temp you set.
I leave my tank at about 135 yr round.

We were thinking about a tankless at one point, but the single smallish exhaust vent current installed for our gas water heater that's also shared by the NG furnace, the location of the water heater in the four story townhouse and the configuration of the three floors and wall spaces leading to the attic and roof would have made the installation of a correctly sized vent cost prohibitive and we have gas inspectors to contend with.
 
I want to build a homemade solar set up with a pex or copper coil.

I even thought about doing indirect by dropping a septic tank in the ground and having coils heat water in the tank that’s not under pressure. Then have coils of pex inside that tank absorbing the heat and circulating it to my water heater.
 
My Dad used to live in Kansas City and they had a big lake behind their house. They installed a heat pump that used some sort of a heat exchanger setup deep in the lake near the bottom that was used to suck heat out of the water to heat their house during the winter time.
 
We've had our water heater for probably over 10 years now. It's due for draining bc the water inside is not very clean. Not sure if any of the valves even work though and there's no good place to drain it unless I bring in some buckets.

Still feeling like absolute garbage. I'm going to have to change thyroid meds. The stuff they switched me to (without consulting me or my doctor) is giving me arrhythmia and shortness of breath. I got a 3 month supply but I'm about a month or so in and this is no bueno. I need to change it asap. I can barely focus on anything and feel like I haven't gotten any sleep. Didn't help I had to keep getting up to break up cat fights last night. I watched an angry cat pick another fully grown cat up by the scruff of the neck, flip him over and literally throw him off the cat tree last night. He was already in a bad mood and jealous cat comes up wanting attention and bunts the angry cat in the head trying to get in on snuggles. Usually other cats just but back or move away in annoyance. Angry cat wasn't having it. Desperately need to get them neutered.
 
heating that small amount of dishwasher water, 1 or 2 times a week, as compared to keeping 40 or 50 gals hotter 24x7, seems like it would not be comparable, at all.....??
 
for draining water heater, most have a drain that fits a water hose, right ??? you just connect a 50' hose and run it out nearest door or window ??

You are probably correct (that is if you were responding to my post above). By the way, this family does almost two loads of dishes a day. I have no idea why we dirty so many dishes!

I know there's something wrong with that, if WH in basement.... As in water (willingly) flowing uphill. Still, gave me a thought.

If I hook a long hose to WH, and push far end into main drain-line cleanout, and then down the pipe for 8-10 feet... Should drain the WH without a pump, or worrying about getting a siphon going, and, maintaining it.
 
As Frodo once said, basements in my areas would be called swimming pools. Water table is too high/elevation too low to have basements. My water heater is in a hallway with carpet. I believe it used to be the exterior of the house before they added on to it. The original house was the kitchen, a small bedroom, a tiny bathroom, laundry room, and porch. They added a hallway and two more bedrooms and bathrooms to one side. Turned the porch into a living room, and years later added a greatroom off to the opposite side. That's how it was when we moved in. Carpet in two of the bathrooms. Parquet floor in the original bathroom.

The water heater is on a platform in a closet above the cavity for the air circulation compartment of the HVAC. I'd have to either run a hose around the corner and to the kitchen sink (which is higher than the drain) or around the corner through a bedroom door, around another corner into the bathroom, and drain into the tub. Worst case I could line up some 5 gallon buckets (I have several) and drain into them, and then have my brother help me dump them into the tub. I don't want to drain directly under the house in case it contributes to further erosion under there. This is roughly the layout. The water heater is in the same closet as the internal HVAC next to the pantry (its not to proportionately to scale). Mom likes to keep her bedroom door closed as cats are not allowed in. We'd have to keep her door and the bathroom door open and deter cats from going in if we drained into her bathroom.

Did I mention I discovered that my water heater *does* have a shutoff valve? It was hidden behind it. I found out when I was reaching for a cat toy next to the water heater (when the HVAC people installed their stuff, they broke off one of the closet doors and never replaced it). It was basically 1/8" wall paneling on crappy hinges anyway. One of these days I need to replace it.

I forgot to mention that I didn't take my thyroid meds last night because the generic my pharmacist switched me to (without warning) was making me very ill. We're talking cardiac issues, lack of coordination (stumbling/nearly falling), lightheadedness, shortness of breath, and complete exhaustion. I looked up the meds after having those symptoms and it listed them as possible side effects. No wonder my brother has felt so awful-- he's been taking those for months. We both stopped and I feel better today. Still a bit tired but not completely exhausted and I'm not having the other symptoms. I just called my doctor's office and asked for him to approve the pharmacy giving me the medicine that was working instead. Next step is to talk to the pharmacist about switching it back and refilling the one that doesn't make me sick. I'm about to make that call and hope I can get through to a live person.

Just bought and had a professional install a mini split a/c in my bedroom. Used it 3 times and it flooded my floor. Had the installer come out today and saw the condensate line had a break in it. He repaired it but it leaked again. I had 5' of 5/8ths heater hose, so he installed than. Boy, it worked so well he is going to use heater hose on all his installs from

Nice!

I talked to the pharmacy & my doctor's office. I'll be getting a new thyroid med tomorrow. Well, its what I was on before that worked and didn't make me sick.

I'm currently researching a contact cement that won't grab immediately and has a little room for error so things can be moved before it seals. I saw 3M Fastbond but a small container is over $50 and I can only find it at Amazon but some buyers said it arrived dried up.
 
3M 72 is a sprayable adhesive and it is repositionable within reason. It's available on Amazon and is less than what you quoted and won't be dried out unless the spray can explodes enroute to you. I've used it with success.

Five (5) tons is a big one!
 
Since we are headed out to Catalina Island for the next 4 days, and have to leave at the butt crack of dawn this morning, I wanted to flip on the mini-split to chill the room last night, but the better half didn't want to take a chance of another flooding, so I was prohibited from using it. Darn A/C guy was here for 3 hours working on it yesterday, and she is now afraid to use it? SMH
