Hopefully someone can shed some light on this issue because it's driving me nuts.
So I used to have a low-flow showerhead and noticed that the hot water in my condo never lasted all that long. It wasn't awful, but probably in the 20 minutes range. I have a 40gal electric water heater and I'm currently the only person living in this condo, so the hot water use when I take showers is 100% from that and not any other appliances or people taking showers.
I recently bought a new showerhead (Flipside by Kohler) and removed the plastic restrictor because the flow was pretty weak and I was hoping to get a bit better performance out of it.
I definitely do get much better water pressure out of it now, but as a result, I can only seem to get about 12 minutes out of it before the water is too cold to be comfortable and I have to get out.
So far I've checked to make sure the thermostats in the water heater are operating correctly and they seem to be. I checked the incoming voltage (208v. Not sure why it's not 240 but the water heater is rated for both) , Both thermostats are currently maxed out at their highest temp settings (is there any strange possibility that I could get more hot water out of turning them down? I turned them up months ago while I was using my low-flow shower head because I was hoping to get longer showers out of it). The heating elements both show continuity (like 13 ohms I want to say?) and when I run the water at full hot , it definitely starts out very hot so it's not an issue with the water not being hot enough to start.
The one common item I haven't checked is the dip tube, only because I believe the only way to access that would be to cut my plumbing apart to remove the cold-water input . The water heater isn't more than about 10 years old (I believe this building was constructed in 2005 or 2006) so I wouldn't really expect parts on it to start failing already. I'm just not sure what else to try, or if a 40g water heater just isn't enough volume to keep the amount of hot water I'm hoping for ?
any and all ideas are appreciated, these short showers are getting a bit frustrating!

The best way to find out about pricing is to call plumbers in your area and request quotes. Anonymous internet plumbers who have no stake in your job (i.e. accountability) are not the right folks to ask regarding the cost of your job, what you already paid, a bid or quote, etc.
When asking questions please post pictures of the problem fixtures and piping, this can help enormously when it comes to diagnostics.
We do not find chemical drain cleaners conducive to good upkeep on most plumbing systems, we do not encourage their use at all; in fact, we may make fun of you for wasting your money buying them and possibly risking your well being for using them.
