The RH in the basement is staying down around 50% on average..
The KillaWatt meter is set for 22 cents per KWH and it's showing $11.20 per month.
Power should cost 50 to 60 bucks per summer to keep the whole basement dry.

Plus, I'll be needing some more filters.. https://www.amazon.com/dp/B009AW31SC

The smell of the basement is very fresh-air-like now. So far, we are really liking this machine.

During the winter, and when it's over-cast, the A7 ASHP Hotwater heater takes the RH down too..


Today the local station says it.. Feels like: 100°F

The factory muffler kit definitely makes it quieter. We folded an old rug and put it under our unit and made it even quieter. It's a little louder than I would like, but is still tolerable in our living room.

I looked at the design of the muffler, and I think that I could duplicate it in my shop.
However, since it's in the basement, the noise isn't much of a problem.

The comfort down there is fantastic, I used my heat monitor pistol,
and found out the basement slab is still very cool, in August?
Today it was 60F in the SW corner and 50F in the NW corner..
Seems like it should be 8 or 10 degrees warmer..
Maybe the last few winters were colder than most.?.

It's just a piece of sheet metal lined with foam. Plywood would work just as well as the sheet metal.

Filter day!
 

Got the correct filters today, and the heat pistol is telling me the air exhaust vent is 90F, with the basement at 71.4 F right now.
It 'feels' like it's got more air-flow now. Which I like!
The quality of the filters and the pre-filter is excellent. The USMail didn't crush the shipping box too badly..

Current RH in the basement is 50% :D And, there is no 'basement odor'.. :p

WOW! Outdoor RH just dropped down to 45%. Makes me wish the basement ventilation blowers could dry the basement better. Changing all the air 3 times an hour, should work okay.. But nope.. It's fine keeping the radon levels down..



I'll have to remember to shut it down, when I do any dust-making work in my shop..
The standard heating system filter I've been using doesn't seem to be dirty,
so maybe these new filters will last a long time..

Now that fall is in the air, there is less dampness in the basement..
And it's getting cooler around here too. (at least this week).
70 hours ago, I reset the KilaVolt meter and tonight it's log shows a lot less run time/less KWHs..
The cost is down to just under $5 a month as of now..
So, I'm going to guess the average for a summer, is going to be about $7 per month.
At 5 months per summer is going to cost us around 30 bucks.
I believe it's money well spent. The Santa De Classic rocks!
The air downstairs has been great since buying this unit..

When it starting getting cool,
 

480 hours (20 days) ago, I reset the KilaWatt meter and now it's showing $2.20 per month. (20 cents per KWh).

Right now, Humidity: 96 % Outdoors. In the Basement, it's 50% RH.
It's not running very much, but the min & max is staying within the 48 to 52% RH range.. (64 to 66°F range).

When the basement temp drops a little more, I'm assuming the Santa Fe can be turned off for the winter.
But for now, it's not costing much to run, so it's staying turned on.. (7 cents per day).

We noticed the Santa Fe wasn't running last week, so it's been shut down for a while.
The humistat displaying min 42% & max 45% RH.. That's a pretty dry basement so far..
I think it's time to put a dust cover over the unit..

Wow, the basement was at 75% RH today! (Outdoor RH is 40%)
I had been using the ventilation blower to bring cool dry air into the basement, but it hasn't been working very well..
Have done this a few times this spring and it's done poorly...

So, I'm going back to the Santa Fe and see if any R410a has leaked out over the winter..

So far, it's running okay.. Even if it's still cool(67F) in the basement.

What temperature was it outside when the RH was 40%?
