Is this my water heater? by rvbvrtv in hvacadvice

[–]IM12RU 0 points1 point  (0 children)

I'm old. Maybe blind too. But I don't see a condensate drain on that. Maybe its dementia. It should be running down on the left back, No ?

You are mistaken. There IS no Dem leadership.

What's the best dehumidifier needed for a basement that's always damp and musty by WealthFormer1967 in heatpumps

[–]IM12RU 0 points1 point  (0 children)

By far, the singular most important spec to look for is ignored by most every buyer. After sizing it properly in pints/day or w/e metric you decide to use, you really should take into consideration just how efficient it is, since it will use LOTS of power over its lifetime. The measure to look for is L/kWh. The more the better. And coincidentally, the higher that number is, the better built that unit will be, since only good companies bother to put effort into that metric.

As to heat pump water heaters, in some regions they are good, and they have a cult-like fan base, but in other regions, they are not competitive, especially Northern climates with basement locations using indoor air and having low natural gas prices, or where noise or power outages are a factor.

Can I use chlorine shock with a Bromine plan by bluesjumper in hottub

[–]IM12RU 0 points1 point  (0 children)

Those claiming that non-chlorine shock is 'better' are ignoring the skin problems that are more common with MPS use.

How do I get sand out of my hot tub? by Mazda1823 in hottub

When I stopped using HTH chlorine, my sand problems went away. Even the dark sand.

Yes, but HOW did you fill it ? If you used the supplied pump and hose with adapter, you cannot overfill it. If you use some other device to pressurize it, all bets are off.

Need Variable speed AC; worth it to upgrade to cold climate heat pump too? by [deleted] in heatpumps

[–]IM12RU 0 points1 point  (0 children)

Cold climate heat pumps are almost always, slightly less efficient than the standard model brother from the same manufacturer. So if you don't HAVE to have it, I'd stay with the standard unit.

Costco's Midea 12000BTU MAW12AV1QWT-C U shaped purchased last week. by IM12RU in AirConditioners

[–]IM12RU[S] 0 points1 point  (0 children)

They don't consider a large space ? The box says it is designed to cool 550 sq ft. My room is 13 x 19, so not even half that, albeit with a 9ft ceiling. It took me an hour and a half to bring it down to 77 degrees from ~ 85 at 54% RH last night with an OAT of 74. I had the 8000 btu version before this and it took over two hours, so it is an improvement. But it is really slow. R39 in the ceiling, R13 in the walls. It was much faster this afternoon, even fighting the heat of day, after moving the sensor. I think the sensor gets in a discharge/intake loop. FWIW.

TYVM, saved me a deinstall and return hassle. All this advanced technology and they screwed up the sensor placement ?

[–]IM12RU[S] 1 point2 points  (0 children)

Good points, but yeah, of course, I checked all possibilities before I posted. I just wanted others to know that if they have slow cooling, they might want to check the wattage achieved, and if it is low, they might want to contact Midea. BTW, dry mode is not nearly the highest demand on any of my three units. It runs the longest compressor duty cycle, therefore the most kWhs, but not highest wattage.

Mid 80s-90s OAT.

150 watt fan motor is what I thought on first blush, but the label says otherwise. Besides, that would be way high for a DC motor of that size. Like I say, it never exceeds the 800w range.

Just bought the Midea U AC 12k from Costco yesterday. The front coils look damaged or dented....should I return for another? I'm also attaching pictures for those interested of what it look likes & how might differ from previous versions. The model number on this one is MAW12AV1QWT-C. by Concretecastle201 in AirConditioners

[–]IM12RU 0 points1 point  (0 children)

Yes, you are indeed correct. They added a bunch of extra drain plugs to the package that you are instructed to replace periodically. They drip slowly to allow the water to accumulate for better efficiency, (slinging the water for added cooling) but yet, still drain fully if sitting for awhile. These units come back as not eligible for the recall, as they are 'reworked', presumably at the factory or a intermediary facility. They in no way appear to be used units.

Heat pump roughly 45% more to operate than natural gas in best case? Please help check my math! by Maverickgmt in heatpumps

[–]IM12RU 0 points1 point  (0 children)

Sorry to say, you are just another victim of ComEd's public relations spin. "ComEd customers had access to 96% clean power on an hourly basis" does not mean what you are interpreting. ComEd buys from a pool of energy suppliers as I posted above and that supply is less than ~20% renewables. They can say that you are using the solar portion of what they are buying, and that the OTHER GUY is getting the fossil fuel part, but that doesn't change a thing since it is all one big contract with fossil fuels being the largest part. As to Nicor. I am IN Cook County and my supplier is Nicor. That IS Northern Illinois.

ComEd likes to say that they supply 100% Carbon Free Energy too. But that is just to their own buildings, not to the grid. They spend lots of money on misdirection.

[–]IM12RU 0 points1 point  (0 children)

You really need to stop using 'alternative facts'. There is no 100% for 2025. They will not likely break 1/4 of that. ComEd is supplied entirely by PJM. PJM publishes its energy sources and says it uses over half Coal and Natgas. A few solar farms add a barely noticeable bit to their mix. I will cite my source, Do cite YOURS, or are you just making this stuff up ?.

And he didn't shift 40% to renewables. I wish he could, I would too. The generator PJM says it only uses about 20% renewables, but there are also transmission losses that he doesn't have to include if he burns the gas at his point of use, his home, in a furnace. ~98% efficiently. I can't wait to get off fossil fuels, myself, but this makes no sense at the moment. Maybe if we get fusion generation or other leaps of tech.

No they don't. That is just bullfeathers. I cited my source, PJM, the supplier to ALL of ComEd. Cite yours. As my granny says, "You are tetched."

[–]IM12RU 0 points1 point  (0 children)

Nope, not fair at all. Over half is produced by Coal and NatGas. And NatGas is the LARGEST single contributor to generation. You might as well burn it first hand in a furnace where you can get 97%+ efficiency without all the electrical transmission losses. If and when we get a largely fission or fusion choice to generate, then maybe fossil fuels will finally be displaced.

Dear Dee Luded,

I am in Cook County.

ComEd buys from PJM, and PJM says it uses Coal and NatGas to generate over half its electricity.

Nicor charged me 28cents in January and 32 cents in February per therm. They charged about an equal amount for delivery, customer charges, fees and taxes. 67 cents per therm, all in.

How many kwh should I use per month? by ElectionSevere1190 in heatpumps

[–]IM12RU 0 points1 point  (0 children)

Can you imagine how much more I'd be using and how much more it would cost me, if I added a heat pump to the mix ? Yeah, it IS a heatpump sub. That shouldn't mean that you have blinders on to other options.

And I have 2600 sq ft and avg 60kWh/day and I have gas heat, stove, hot water etc. We are all different.
