What does it have or do that allows it to deliver useful heat down to minus 13F? What do they do to keep the evaporator from icing up more slowly than a conventional heat pump.

I found the following which does not seem to be the whole story:

Perfect comfort to Minus 13 degrees!

Enter Mitsubishi’s new Hyper Heat system. Hyper Heat uses something they call Inverter technology- by using a special phase-changing liquid, they can still withdraw heat from the surrounding environment until temperatures dip below -10.

The best way to think of this is to think of this is to compare it to an ice cream scoop with a heat exchange liquid built in.

The scoop can remain warm enough to easily go throug

In an ECM motor the stator poles are sequentially energized to pull/push the rotor around. Is there any attempt made to conserve the energy in the magnetic field of one pole by switching the current to the next pole?

Has anyone used a VFD to derate the output of a residential 240 volt 60 cycle compressor? Was the project successful?

Where does the "cold" go in a residential heat pump water heater? Is it ducted outside in the winter or does a fan simply blow over the evaporator and cool the space that the water heater is in?

I found this link, but the info may be obsolete.

If a condensing unit is rated 240-208 volts, does running it at 208 mean that the compressor runs slower (and at higher slip)?

And if a transformer is rated step-up from 208 to 240, can I use it to step down from 240 to 208

Is it possible that attics are not vented in New Zealand?

Look what came up in r/hvac:

My experience has been that they're a bit over-sold/marketed; it certainly won't fix any cold issues you have, and is no replacement for heating or insulation. Do those first. Most of the humidity in your house isn't from outside; it's from cooking, showers, people breathing etc. Make sure you're extracting (not one of those rangehoods that just recirculates) air from places with high humidity - particularly the kitchen and bathrooms. Bringing in actual outside air should help, but I'd be suspicious of the attic. NZ attics don't usually have deliberate ventilation like US ones often do, so I suspect you'

I make a gelatin dessert from Knox gelatin, cherry juice that I reconstitute from concentrate and banana or mango. I have also used lemonade as the liquid.

I use 2 envelopes of gelatin powder to 2 1/2 cups of juice which I sweeten with NOW liquid stevia extract. One batch is 2 portions.

The problem, such as it is, is that I get a rubbery skin on the bottom of the mold. My mold is a round tupperware which I cover and put in the fridge after the juice-gelatin solution has cooled to room temperature.

How can I not get that rubbery skin?

I am using the gelatin as a medicine to reduce muscle soreness from swimming. My wife likes the gelatin for its flavor and texture.

Do any residential compressors have a better method of bringing power to the compressor terminals than the little "flags" that are welded to the round terminals with a fast-on slipped onto the flag?

There is a reason that fast-on connectors are not used in airplanes.

My flag completely burned up. I cut the fast-on to leave just the barrel and tied the barrel onto the compressor post with tie wire. I have 4 tie wire jury rigged loops on one compressor post. I ordered a Term-Lok from ebay.

If you close the registers and block the return(s) by wrapping the filter in plastic, you can save yourself some corrosion in the air handler, especially on the motor. If air is free to migrate into the ducts, moisture condenses on the cold parts and causes corrosion.

Be sure to undo this in the spring. The blower motor really screams if it gets no air.

How long can I let them grow? What night time temperature will destroy or deteriorate them? What is the best way to prolong their usability after they are cut? I have 5 growing on two oak trees. They get almost no sun this time of year. I am in Smithtown NY.

I cut one this afternoon. I broke off a few "flowers", which reminded reminded of cauliflower. There were thin green fibers trapped in the white pieces of mushroom. They seemed to be too thin and too round to be grass. I pulled them out if possible or cut the flowers to relase them. I baked the flowers at 350F with some olive oil, garlic powder, onion powder, salt and pepper. When done, I added them to Delicata soup. The mushrooms were

I have a 2 ton air handler in a closet in FL. There are no return ducts but the closet has a louvered door to allow air to return to the air handler. The problem is the sound of the moving air and blower.

The proposed solution is to cut an opening in the back of the closet and build a return duct that leads to an adjacent room and build a solid door that seals against the closet frame with a gasket.

If someone has experience with quieting air handlers or other noise, please make recommendations about materials for the duct, door gasket and the door itself.

The duct will run through an adjacent closet, so I only need to make one side of the duct to form a square duct and then cut open the

We leave our Long Island NY house for 5 months to escape winter. I drain all the pipes, including the oil fired boiler, tankless coil and baseboards, put RV antifreeze in the traps and let the house freeze.

I would like to put an antifreeze in the boiler and not have to drain it and refill it.

What do the plumbers recommend? What percent antifreeze do I need? The lowest temperature I see was minus 7 in 1988. The antifreeze can turn to slush and that would do me no harm.

How can I test to know that I need to have the cesspool pumped?

The toilet flushes but waste backs up into the sink in the basement. I ran a 50 foot x 1/2 inch snake through the cleanout in the basement and that did not solve my problem. I poured 5 gallons of boiling hot water into the tub and it went down with no waste in the sink, but when I flushed the toilet I did have waste in the sink.

I had no problems in November and this developed when we got back home on Monday. The house is in Smithtown NY.

A month ago I asked about a riser for a kitchen faucet. I made one myself because apparently they are not available for sale. I made the block from wood and covered the wood with formica. I bonded the formica to the wood with with PL Premium construction adhesive. You do not see the edges because the formica is black and I blackened the edges of the formica with a magic marker. I sealed the faucet to the top formica with silicone and sealed the block to the sink with the same silicone. The riser is 3" high and 2 5/8" deep. The faucet is a Delta faucet. It has been in service for 2 weeks and there have been no complications.
