Yea! It climbed up to 10F !! I've got the Sanyos turned on!
It's nice to save some oil.. We've burned more this winter,
then the total burned since we started using the Sanyos..

What's the low temp spec on those GREE 24k BTUh units?

5 deg that might not be good for you.

The mitsubishi hyper heat might be better for you.

Here is a quote from them
"Our H2i MSZ-FE systems performed at 100 percent rated capacity at 5 degrees Fahrenheit and even produced heat down to minus 18 degrees Fahrenheit."

5 is okay for normal Boston area weather. But won't be able to handle this global warming weather.
I think down to Zero would do it for now.

I was just out pulling a few tons of global warming off the roofs..
The backyard Sanyo is now completely buried under about 4 feet of GW snow.
And it's surrounded by deep snow, that you can't walk in, you have to make
a ditch to walk in.. It takes too much work..

But, we aren't going to need it, since it will be 8F in a few hours. And zero before morning.

It's hard to walk in waist deep snow that's mostly light powder. With hard layers.

If this had been heavy snow, half the houses in MA would have collapsed roofs by now..

I lost a snowshoe on the way out the fixed panel array.
I noticed the missing snowshoe, when my left foot suddenly broke a hard layer and I dropped 3 feet..
Up to my bellybutton.. Of course I fell backwards and sunk.
I was over my head, sitting in a little snow pit.. It's hard getting out of a hole,
when you get old and dumb.. Never gonna do that again..
If the snow covers up the PV, then so be it. It's God's Will..

We can't shovel off the deck, under the railing, because there is no room left.
The snow is piled up to the deck floor level. I was trying to stomp some down,
and fell backwards a few times.. What a PITB.

This reminds me of my of the Blizzard of 78.. That spring, we went house hunting in Austin Tx..
I had a dream.. Even put down a down payment..

Yeah the Gree like it's similar standard models of the past is best for South Carolina winters if you don't have heat backup.
Just because it runs at 5degrees doesn't mean you'll get a lot of heat out of it, or won't get quite a chill as it enters into defrost often. When it's blowing 80degree as it tapers into and out of heating mode, it's providing heat, but it doesn't feel that great if you are close to it.

My late model Fuji, similar to the Mits hyperheat, doesn't start to drop off til it gets close to zero, the spec says 100% at 5degrees. It has run in consistent in -20degree weather, although it goes into defrost almost as much as heating mode and you def notice it more when its -20 outside. It has run in under -20degree weather for periods without shutting down, the service manual details an error indicator that requires a hard power off reset, but I never saw it.

I have had the error indicator for ice buildup causing the blades to stop. Once from the pan build up, and once from a heavy blowing snow blowing into the face of the blades and face of the machine, causing icicles to form on the rounded face and head inward towards the blades. There were all sorts of broken icicles on the ground, so it mulched them up for a while.
The fan stops spinning in defrost which gave the icicles time to form, and then get chopped up when heat resumed, but eventually it was overcome.

I feel for ya xringer as you've taken the brunt of GW this year.
I wouldn't expect every year to be like that, but you'll have some of it.

We've been really lucky here as all those systems went around us for the most severe parts.
Last year we weren't as lucky, especially with those cold spells.
I feel your pain with that multilayer snow, don't miss that at all - but the year isn't over yet!

This new normal isn't great for operating efficiency, with heat waves and big blizzards

Now that it is warming up and I know we have made it through the winter without using any natural gas heat.

Using the mini splits in the summer allowed us to carryover a good bit of solar power to the winter to heat with.

We only used our mini splits to heat with this winter. If I compare this to a year we used only natural gas to heat with we saved $725.

The reason we were able to save so much is we completely covered our power last year with solar power.

The mini splits really shine in the summer. They are a lot cheaper to run than my 4ton AC unit.

This allows me to push the unused power to the winter. It is nice when a plan works out. We love the heat they put out.

We really did not conserve heat was set 72-74. Summer AC was set as cool as we wanted.

About a year ago I installed two Mini splits in two small bedrooms 137.5 Sq FT.

I put in 9,000 btu Gree inverter 27 seer units. These units will ramp up the compressor as needed.

They have worked perfect for heating and cooling. I also have this unit in my bedroom/office.
They let you change the temperature one degree at a time. This makes us to be at the right temp all the time.

I was concerned about the bedrooms being too small to have 9,000 BTU unit.

I have seen no issues at all and they keep the rooms comfortable all year around.

I have had my unit under two years and the boys units almost 1 year we would get them again if I have to do it all over.

I like to come back and do an update once in a while once the shiny has worn off.

It's good to see people are getting good results from their mini-splits.
After the last couple of winters, I'm thinking of upgrading to some high-performance units. Or, moving to Texas..

Most of the time, the Sanyos are great.. Like today, my wife just shut down the heat in the den..

We have been having a wetter than usual late spring / early summer . So it has been cooler than normal .

We are predicted to have a thunder storm latter today / tonight . Currently cloudy , 78F 65% RH wind 7 mph predicted high 79F .

Gradually warming to a predicted high of 93F , Saturday .

I am loving the new MS we installed in the bedroom . :-)

God bless

It is a very hot 95F here. My house is set @78F and the whole house is only using 2KW
power right now. That is for everything running. Pool pump, aquaponics pump, TV ...

We are running all four mini splits. That is one reason why I like the Mini splits.

We are making 7.5KW in solar power right now.
