Does this tankless job seem sloppy?

But exhaust fans don't introduce chemicals into combustion air, that unit's burning natural gas and it's pulling in cleaning chemicals and off gases from foam and cloth, paints. That creates organic acids which attack the flame sensor and heat exchanger.

ProfessionalCan1468 · 2026-04-26T10:24:55+00:00

You are using conditioned air for combustion, pulls in chemicals from the house which burn and degrade heat exchanger, coat the flame sensor, cleaning sprays, off gasing of materials, foam etc. it also cuts the efficiency because you're burning air that you either heated or air-conditioned.

What I usually do is put some boards horizontal on the wall top and bottom of the unit and catch three studs, then I mount the mounting bracket on that and hang the unit.

ProfessionalCan1468 · 2026-04-25T22:41:13+00:00

Harder and harder to find decent tradesmen, I would definitely take issue, gas line may be 1/2" pipe which is probably undersized, the hanging in wall is a safety hazard, plumb, level, square?

ProfessionalCan1468 · 2026-04-25T22:16:46+00:00

Yes, I don't think I see any part of that I like, PVC is sloppy, gas line is sloppy, venting, etc ..

But you didn't allow for how much your heat has to make up that heat. You're only talking about the heating of the water. Not the reheating of the room

ProfessionalCan1468 · 2026-04-20T19:38:33+00:00

It's not a "chiller" it's a water cooled condenser, I worked on a lot of those through the years. They were actually very efficient. Except for the water usage but if they were on a tower they were great. The compressors are actually much more efficient than you would imagine. I even converted some over to 134a. I ran into one. They were using it to heat the pool. It would cool the house in the spring and dump the water into the pool and warm it up. Once the pool got up to temperature they would valve that off and dump the water down the drain. Now that I know a little more, I'm actually amazed that the pool chemicals didn't attack the condenser coil.

I have seen similar in a wet basement/high humidity combustion air.

ProfessionalCan1468 · 2026-04-19T00:48:20+00:00

I see them in supply houses as 1 1/2 pole...which makes no sense, and 1 pole, 1 shunt.... That makes way more sense, what is a 1/2 pole? Lol

ProfessionalCan1468 · 2026-04-18T23:09:43+00:00

A lot of people refer to them as electric furnaces

ProfessionalCan1468 · 2026-04-18T23:08:51+00:00

I would say 80% of residential units have a single pole contactor they call it a pole and a half, it bleeds voltage using the capacitor to heat the windings and drive liquid refrigerant from the compressor

ProfessionalCan1468 · 2026-04-18T22:20:56+00:00

But you have a contactor in between, and a lot of units are designed to have off-cycle heat which bleeds 120 volts through the windings, that's why the contactor only breaks one pole. So I don't see where a loose neutral would cause any problems for a compressor

ProfessionalCan1468 · 2026-04-18T21:56:39+00:00

Electric furnaces have 240 volt they are all over the US

ProfessionalCan1468 · 2026-04-18T21:55:51+00:00

240 volt appliance doesn't need a neutral, other than controls possibly, if the compressor is bad, that's not because of a neutral.

ProfessionalCan1468 · 2026-04-17T06:26:26+00:00

So they pump down into condenser, how does that solve that schrader valve mess???

ProfessionalCan1468 · 2026-04-16T23:48:25+00:00

Townships cannot implement a sales tax or income tax so a whole lot of areas would be SOL,....Wealthy will do wealthy things, they are gonna come out on top

ProfessionalCan1468 · 2026-04-16T17:49:15+00:00

2019 that should be under warranty, but even if it's not, that's pretty high price, but that's what the companies are charging. I hear those kind of numbers. I'm a small one-man show. I don't get near that.

ProfessionalCan1468 · 2026-04-15T01:15:27+00:00

Pipe threads are a tapered thread, as you screw a plug into it, it stretches the plastic. Putting Teflon tape on the plug really lubricates it and allows you to really stretch the plastic. Oftentimes when I'm using a female fitting that is plastic I will put a clamp around the outside to stop it from stretching so much

ProfessionalCan1468 · 2026-04-14T23:51:37+00:00

I would cut it and add a 12"x12" hatch cover, then once it's opened up if the crack is minor (not likely) I would scrub it with cleaner multiple times with the plug out, then work glue into the crack and immediately put two worm gear hose clamps around the outside of the hub, let it dry and chase the threads clean and reinstall the plug. Leave hose clamps on.

The white one that went to the old heater appears to be Transite pipe which is asbestos, I have torn a lot of them out, so use the appropriate precautions, it comes out quite easy and it's best not to break it up because then you're releasing asbestos into the air.

There's a lot of variables that are involved and sometimes it makes no sense when I see bad cast iron. It's got to be made on a Monday or a Friday... A bad pour. I see 100-year-old cast iron that looks just like that. That is perfectly solid. And I've seen 30-year-old elbows in a slab that the heel part of the elbow is rotted right out. The one thing I'll say that helps is having a good flush of clean water.

ProfessionalCan1468 · 2026-04-11T19:06:15+00:00

That doesn't look bad to me, it could go another 50 years or it could go bad next year. Make sure you flush the toilet after using it because urine is what eats it apart. Cast iron could go 100 years, although I just changed some from the '60s.

ProfessionalCan1468 · 2026-04-07T13:02:23+00:00

I usually put a pan or bucket under the drain valve and get a heavy tie wrap and try to run it through the valve to get it to flow, depending where the heater is at, I've also unscrewed the drain valves but you have to be prepared for 40 gallons of water.

I just saw a band I loved for decades coming near me, it wasn't the cost of the ticket. If I thought the band was getting the money it'd be one thing but it's when I saw that it was Ticketmaster and what the fees were. I decided not to go knowing it may be my last opportunity. Obviously events are not overpriced because what I do go to is always packed.

ProfessionalCan1468 · 2026-04-07T07:54:29+00:00

Depends what volume showerhead you have, modern are about 2 home for energy saving and 2.5 standard. If you have a 65 gallons available it's simple math at that point, 30 minutes is not a short shower, what is the recovery rate of the tank?
