My Man Cave Remodel (8 Viewers)

Nice. But do you have any concerns about how long it could take to get hot water to the outlets farthest away from the heater?

Not really. My house is a ranch style. It will be installed in the laundry room just under both upstairs bathrooms and kitchen. Longest hot water run is probably 15-20ft.
 
Installed the stem glass holder. The glasses in the box don't fit. Too thick. Some paint touch ups, caulk the backslash, install receptacle cover and the wet bar is finally done.

You built the wet bar around the Terribles floor mat didn't you? Admit it. Looks awesome btw
 
I was actually disappointed when I saw a pic of Tommy because in my head he should look like Terrible Herbst.
 
Decided not to move the old water heater back to the original spot. I purchase one of these today. :eek:

A little update. I canceled my order for the 8.4 GPM/157,000 BTU model and picked up the 9.5 GPM/199,000 BTU model brand new in box off eBay for $650. :eek: It sells for $1299 at Home Depot.

Had 5 of them, 2 left. Included a tankless valve set for free.

And I don't see that the run would be any shorter if he kept the tank - he put the on-demand box in the same spot the tank was, right?

Tempting price... but I don't want to have to deal with the vent. Direct vent, right? The tank here is vented into the chimney.

My understanding is that hot water tanks also heat the lines via conduction when the taps are closed, so the water in the lines never really cool down. With tankless, they do, so it may take longer for hot water to reach the tap if you replace a tank with a tankless system.

The hot line out of the heater never gets cold, no, but it certainly cools down. I just checked here... hot water was run half an hour ago. Six inches off the top of the water heater, the "hot" pipe is warm in my hand, but not hot. Just 24" out from the heater, it feels a little warmer than the cold supply, but I certainly wouldn't call it warm water.

Tank or tankless, the water standing the the pipe won't qualify as "hot", save the first couple inches. On a cold day, the whole tankless might be cold, which would probably make for more of a delay than the couple of inches of pipe outside the tank.

Also, Tommy isn't using copper... it's the copper than conducts more of the heat out of a tank, not so much the water.

Hmmmm... then again, the cold feed was probably also getting some heat out of the tank... but the difference between 6" and 24" out was still huge on the "hot" side...

Correct. At 94% efficiency the exhaust gases don't get hot enough for a chimney. This unit is direct vent with schedule 40 PVC. Up to 5' in 2" PVC or up to 38' in 3" PVC. Mine will vent right out the rim joist so I will use 2" PVC. It uses two pipes, one for intake and one for exhaust. Other style tankless water heaters are in the 80% efficiency range and use a concentric stainless steel vent because the gases are much hotter. That venting system is much more costly especially if you have a longer run. (I'm no guru on these, I just did a lot of research) :)

I will no longer need the original metal chimney pipe after I go tankless. My furnace is also direct vent. I got rid of the wood stove when I re-did the basement so the other chimney is not needed either. When I get a new roof, I will have both chimneys removed.

Correct, a tank style does but only so far. They do recommend insulating the hot water pipe for long runs. I'll see how it works and will insulate if needed. All of my water pipes are open and accessible in the laundry room.

Also, Tommy isn't using copper

So far I only used the PEX on the new plumbing to the basement bathroom and wet bar. Everything else is copper. Not sure if I will use PEX or copper on the tankless yet. 3/4" Type L copper is like $25 per 10ft. Pex is $3. LOL Should be an easy decision right!?

This is an overview video that I found of the exact model that I have. Good video on how the condensing works to make it more efficient.

 
All 5 have sold. Did you end up getting one?

Nope. Technically, it would have been for my mother's house, not mine... Even if I paid for it and did the work, it's hard to convince her to replace something that hasn't already failed... She's 7 years into a water heater with a 6-year warranty. It doesn't need replacing, yet.

When I last looked into these - five years ago? They were less efficient and cost more; when her tank goes (probably in the middle of the night), I'll probably get a phone call and come running. With any luck, the new ones will be as cheap, then, as this deal was, now.

And thanks for the vid - I didn't know about condensing secondary heat exchangers. Explains the reduced venting needs and the improved efficiency; very cool.
 
All water lines hooked up and tested. No issues or leaks with the PEX.

I used small pieces of pipe insulation where the hot and cold PEX crossed paths and were touching.

Bushings to protect the PEX from the metal studs.

PEX tied into the existing copper.

We got water! ;)
 
Some pics of the finished bathroom, which by the way has been fully tested today. ;)

(still have to install the shower head escutcheon plate. It needs to be trimmed on the band saw to fit properly. Clearance issues with the ceiling and top of the shower stall due to raising the floor for the 2" trap. It will sit flush on the wall above the fiberglass surround)
 
All 3 have sold.
 
The last piece to the puzzle. :D

Finally!!! There is no more work to be done in the finished area.
I just remembered that we still have to re-install the railing on the stairs. I was going to re-paint it but I think I'm going to send it out to get powder coated. I also want to get the 2nd refrigerator down into the laundry room and the old hot water heater out before it goes back up.

I'll post updates when we install the tankless water heater.

Planning a meetup when all done?

Definitely. Sometime next year though. I have to schedule some vacation days (I work weekends) and coordinate with the wife so she can take the kid and dog to the family shore house.
 
Power tools are fun. :D

REMEMBER: Always wear your safety glasses! :)

This monstrosity has served me well. It was here when I bought the house. It had 3/4" plywood shelves and and mix of 2x3 and 2x4 shelf supports. (I salvaged the wood) I need to make room for the other refrigerator so it has to go.

I don't want to risk damaging the walls getting it out of the basement so it is getting cut in half. :eek: I may put it back together and use it in the garage.

That side door is very strange. I put the wheels on it.
 
The carnage...
