My awesome neighbor / electrician hooked me up with an hvac tech who's gonna do the do for $50 an hour and said 1-2 hours tops, so I'm not salty.
What size is that unit? My 24k Aura pulls a good amount of power every once in a while heating. Listed some power details here: https://diysolarforum.com/threads/senville-aura-24k-heating-results.72030/It's nice.
I don't care for it not wanting to turn off when it hits the set temp under the "follow me" setting and Senville agrees that that's not how it should work, so they sent a new mother board for me to install (yay).
It appears to use something like 1200-1300w early in the morning as I program it to shut off at night and turn back on an hour before the alarm clock goes off, so it's a bit of a pig for a little bit.
The pig tail was a wee wee wee bit too f''n short and I didn't feel like adding wire to it, so I used some left over conduit. Yeah, it's weird like that.
I didn't use the putty but instead sealed it off with caulk, roughly 1/5th of a tube. I just remembered to put down on my to do list to run a bead of caulk along the top of the casing. I installed it on a slope and this side of the house doesn't really get hit by wind driven rain, but just to be sure to prevent water intrusion.
I used a foil backed insulation and made a boot around the valves. The lines are encased in the original insulation all the way down to the valves.
This little unit and my high efficiency wood fireplace handle the heating for this 2,600 sq ft house easily, but II do notice quite the draw down oon the batteries, esp. on days like today with little solar production.
This is why I went bigger with my Aura to 24k for the 1k sqft. Temps going down to -15 tomorrow and will see how it does. So far holding set temp at 0° outside. Too cold to be at the cabin so will be monitoring remotely.It's much colder than normal right now. Roughly 0*. I'm looking at the 18kpv and the house is using 2600 watts? Fridge might be using a couple hundred, fireplace fan uses 60 watts, got a couple lights on and charging the battery for the ego blower.
I shut the mini off and checked the use on the inverter and it's approx a 2,000 watt difference!
This senville aura unit cannot heat the master area over 70*. Right now it's struggling at 68*. This area is a bit over 500 sq ft and the aura 12k is supposed to be good to 700 sq ft. It's supposed to heat down to -22*. Arctic? Maybe so, but it won't heat well.
From my 3 week experience, I do NOT recommend the Aura 12k for even 500 sq ft of space where you might actually get temps close to 0*.
The efficiency drops to below 100% at some point. What that means is once 1Kw of power is used to discharge less than 1Kw (3,412 but's) of heat, then it would be more efficient to use a radiant electric heater which is 100% efficient. While a heat pump might be able to heat to -22F, that doesn't mean it is the most efficient use of each Kw.It's much colder than normal right now. Roughly 0*.

I don't think it's leaking. HVAC guys don't sit around for hours doing a leak test. My guy did something with the refrigerant to really clear the lines which took a little bit and did the pressure test for maybe 30 min.This is why I went bigger with my Aura to 24k for the 1k sqft. Temps going down to -15 tomorrow and will see how it does. So far holding set temp at 0° outside. Too cold to be at the cabin so will be monitoring remotely.
Any chance you have a leak? Before releasing refrigerant, my nitrogen pressure test held at 400psi for 12 hours and my vacuum test held at 120 microns for 6 hours.

I'm not a pro but I recently installed the Fujitsu 09LZAS1 (the RHEEM/RUUD version). When you put it in economy mode it forces the compressor to limit itself to 60% max and that way you get the maximum efficiency possible, as long as you're willing to wait if it needs time to reach temp.I just want to get some opinions on a couple different Mini Split Systems we carry and what you all think of them. We primarily push customers looking into ductless systems towards the Mitsubishi Mini Splits. They're easy to get ahold of (ductless systems are becoming more popular around here in Wisconsin, especially the heat pump & superheat options) and they're very easy to install.
One of our other main distributors carries Fujitsu. Now I've never had to service or install one of those systems, so I'm curious to hear from some of you guys that actually have had experience with them. Is there a specific ductless system you would recommend to customers? If so, what are the biggest differences you see between the two systems? (Besides the price)
I've tried to get some answers out of people at our distributors, but I can't have a conversation with them without receiving an extremely biased answer...lol. So I wanted to bring it here because I know I'm going to get more honest answers from people that don't strictly have a salesman's mindset. Let me know what you all think!
Midea ducted. I suspect low refrigerant level(otherwise what else could it be?) . I also suspect they shipped low from factory. I did a vacuum test on two units for 1 hour each with no leaks and one overnight with no leaks so if it's low refrigerant then it was like that from the factory.@1201
What do you have? Any ideas why?
Set the thermostat for 74 before I left work. The water distiller shut off around 10AM.The jump to 1.4Kw just after flipping to battery is the water distiller, it uses roughly ~800W. The other continuous load would be the coal stove ~350W, I really need to upgrade that inefficient 800CFM blower I added....
Looks like the pioneer is using around 600W when it cycles.
I'm guessing the 3KW peak is a compressor on the fridge or freezer.
Looking forward to seeing how it handles single digits tomorrow.

Did you do a nitrogen pressure test? That's the important test as when refrigerant is released and unit is running these things can get to 300-400 PSI.M

I could be completely wrong but I am researching as much as I can
Only a few floor mount models out there for Pioneer. https://www.pioneerminisplit.com/co...lit-air-conditioner-heat-pump-system-full-setSet the thermostat for 74 before I left work. The water distiller shut off around 10AM.
Looks like my Pioneer 12k is averaging ~1KWh in single digits.
@Zwy which model Pioneer do you have?
