Casey finds that the hot water runs out when he tries to take a shower. Not a long shower, every shower. It's just a 12-gallon tank, so that's a 6-minute shower with a low-flow head, less at full strength. We discussed this last April and yada-yada-yada, now it's September.
Builder Matt Risinger just put out a video on tankless water heaters and he points out three drawbacks: 1) they don't work if the power goes out; 2) they encourage wastefulness; and 3) they need more maintenance than tanks. He left me with the impression that a tanked water heater is an anachronism for poor people.
In our case, if we install a unit on the outside (on the south or even the east side of BA3), we can run a gas line from the basement under the new upper deck and straight up to the tankless. This gets us six square feet free in the bathroom and allows us to replace the 36x36 shower with a 54x36 shower as phase 2.
Something like a 155,000-BTU model with 6.5 GPM rating.
Rinnai V65eN ($680 at Home Depot) for example. (They also sell a "value series" for $550 that's 122,000-BTU, 5.6 GPM.)
We need a plumber to extend the gas line and route the hot and cold water from the water heater closet outside. That's maybe 2 men, 2 days = 32 hours. (I've learned to be cautious with estimates.) So, maybe $3,500?
I can move the existing water heater power to an exterior receptacle.
Among the positives that Matt Risinger lists is that if one goes away for a while (Casey sleeps at his Dad's, I don't rent the AirBnB), it costs nothing, unlike a tank.
Local plumbers include:
- Gene Johnson, who I don't trust
- Beacon Plumbing, who spend too much on advertising
- Washington Energy Services - their bid was too high for the furnace, but maybe. They sell Navien equipment, apparently
- 2 Sons
- Raymark Plumbing
HomeAdvisor is a waste of time.
