So I ended up doing the work myself I do construction for a living so I preety much know my way around tools and ducts etc... the hardest part was the ductwork to get it back in but that’s because it’s in an attic and weird spot, unit was super easy to install did it in 1 full day. I have a carrier infinity heat pump system about 4 months old witch cost me $14k it’s in my first fl and the mr cool unit blows hotter air on 2nd fl without the electric heat coils than the carrier without the electric heat coils I couldn’t believe it. So far so good I can’t say anything bad about it. I would definitely recommend it. Just sucks that a lot of hvac companies won’t install this because it’s not being purchased through them.

They dont like it cause they cant rip you off anymore! I just paid 900 bucks for a guy to come out and braze a tiny leak THAT I FOUND in my 14 year old Goodman heat pump and I even took the unit apart! took him 10 min tops and it was 600 bucks for the repair 300 for 11 pounds of refrigerant, the next day my reversing valve won't move and it's stuck in cool mode, i find that very suspicious1

[@Taedrin]

@@prowler1992 5kw of resistive heating would only put out 17k BTUs/hour which is not enough to heat an entire home. The heat pump is still much more efficient than resistance heating. That being said, natural gas is probably even more efficient at those low temperatures.

[@-JonnyBoy-]

about half the power resistive heat would need

[@jrherita]

@@prowler1992 fwiw the math works out to like 60 cents per hour when the unit kicked into running 24/7 mode to heat the house. If it ran for 18 out of 24 hours that’s like $12 per day of heat (looking at his charts) for only 1550 square feet of house. Dropping the house temp to like 65 and/or outside temps above 0F would certainly help a lot.

Congratulations Mr. Cool for this great success!! I installed a Mr. Cool 12,000 BTU DIY system in coastal Virginia with concerns about our 'moderately' cold nights. So far we've hit the teens once, I think, and it's kept the FROG at a nice 72 degrees without effort. It's been running flawlessly for almost a full year and has done a great job so far!!

I never anticipated using the unit to heat my theater/studio, but thats what I've been doing since spring has been cancelled apparently. My unit will bring the room from 62f to 68f in about 6 or 7 minutes. I formerly used a 1500w electric space heater that would take a good hour to begin to heat this space.

I'm very excited to see this type of system have this much success! Very happy for you guys at Mr. Cool. To me, this is like breakthrough tech given the overall cost of the unit

[@MrBdliving]

Do you guys have coefficient of performance numbers (COP) for your heat pump at different temperatures? I believe this could help many of us including myself evaluate the performance of your heat pump compared to our current heat pumps. For example on your website you list this heat pump being able to provide 100% heating capacity at -5 degrees. That is impressive because typically my heat pump provides very little output below 32 degrees and my auxiliary heat strips kick on a lot to help the heat pump out and that eats up electricity quickly and shoots up the bill. Your heat pump's electrical demand is lower than my auxiliary strips so the cost could be significantly lower to operate throughout the winter. Is your claim that at -5 degrees your heat pump is 100% efficient or that at -5 degrees your heat pump still can put out 100% of it's heating capacity?

[@sequoyah59]

I'd like to see the COP vs. outside temp. Better yet, amperage draw. I have an LG that is similar. In Feb we went through one of the coldest periods in the last 50 years. Our LG units are ductless mini-splits of the 20 SEER range, LG Red rated for -5 and 100%. As the temperatures dropped the old ancient Lennox heat pump started blowing cold air when the thermometer hit about 24 degrees. The ducts are in the attic and the unit just could not produce enough heat to even overcome the slinky heat loss. At that point I shut the unit down and closed the vents in the ceiling. I took out the heat strips in our central air heat pump. Mini-splits: There is one 9kbtu unit at one end of the L shaped house and one 18kbtu at the other in the den that has LOTS of windows. Construction of about 850 sq-ft is new with foamed 6" walls and R-22 or so in the ceiling. The core 1600 sq-ft is older construction with 6" or about R-19 bats n the walls and the same blown R-22 in the ceiling. The two little mini-splits kept 2650 sq-ft of house warm all the way down to our low of -12. The coldest temp at the most distant location of the house was 68 degrees. Our utility has smart meters and we can get reports of consumption down to the hour. Our worst day averaged a temp of 4 degrees and our power consumption was 128.28 kwh. The worst hour was the -12 and 4.55 kwh. It takes more power to run the hot water heater. I need to replace the old Lennox. It is 24 years old. The question now is with what? A) Inverter type ducted air handler. B) Zoned ceiling cassette mini-split unit C) go for broke with geothermal to heat the central part of the house? We had propane for an emergency and we never used it. We now have a good soapstone wood stove for passive backup if we ever need it.

[@sammarmon3965]

I imagine what is meant by ‘100% efficient @ -5F’ is that the heat pump will deliver the same heat at -5F as heat strips would. So I’m thinking below -5F resistive heat strips are more efficient at heating, even if the heat pump still delivers effective heat. Mind you that I’d expect 300-400% efficiency in more moderate conditions. Here in MidTN we rarely have a winter night approaching 0, so even though I’ve got the wire and breaker for it, I’m not installing heat strips. I’ll take the minor efficiency hit if we have some crazy low temps in the future.

[@Snowcube]

I'd like to see this compared with a natural gas or propane furnace in 2 identical spaces. This seems promising, I'm in MN and up until now having a heat pump wasn't really an option.

[@robertl.fallin7062]

Compared to propane you will save a ton of money at any tempture. Go to: Maine Energy.org to see cost for all fuels.

[@jpaull]

I love it! One note, i see the Sense app wattage is reading about 4600 watts, and for that 3 ton inverter drive system that is about double what is should be pulling. I think your Sense energy monitor is reading Double the actual power. This can happen for a few reasons, but its the Sense monitors issue. I have the same Sense app and mine had this happen as well, so i have to reduce what im reading on the app by 50% to make proper "Sense" of it lol.

[@ori4640]

It's not reading Double the actual power, 3 tons is 36000 BTU's and 10,550 watts hours so in those temperatures the COP dropping due to the fact that the heat pump is near to balance point, so the COP is about 2, and probably the heat pump will not deliver 36,000 BTU's in those temperatures so it's even less than 2 COP.

[@sprockkets]

COP calculation. System was a 3 ton unit per MRCOOL comment below. Assuming 1100CFM air flow (typically lower than 400CFM per ton for heating modes if ECM). Assuming power calculation is only for outdoor unit. Assuming this unit has an ECM motor fan for constant CFM at various duct static pressures. Assuming average 4700 watts, but not taking into account heat lost due to defrost sessions. CFM=(VxAx3.414)/1.08xdeltaT Normally the vxax3.414 is calculated via the amount of power the heat strips took. 1100=(heat added to air)/1.08x17.6 1100=x/19.008 x=20908.8 BTUs added That's 6124 watts. 6124/4700=1.3 COP. For fun, let's use my costs for electricity of 11.4 cents for kwh in winter, and 80 cents a therm. According to the Mitsubishi heat cost calculator, for 1 million btus, a 96% furnace would be $8.33. This ssytem would be $25.62 when -24F outside.To break even, would require a COP of 4. But best I can tell a therm in Grand Forks can be about 58 cents. That still doesn't mean you shouldn't consider this system. Burning natural gas puts tons of CO2 in the air, and thus you are essentially externalizing the costs to someone else in the future. That could be you. And you could install solar or wind energy and not pay anything at all for electricity or heating, or cooling! I'd need around 12 300w panels to do it, and my energy company will pay for energy I send back onto the grid, so no batteries needed at this time. I still suggest if you can, using a heat pump that can heat to -22 but doing it zoned so you don't heat what you don't need.

[@darrowprairie]

@MRCOOL, do you have a list of installers in the Midwest? I'm in Iowa, and none of my local HVAC businesses are willing to install this unit even if I purchase it myself. I'd install myself, but I'd prefer someone more experienced.

So how does capacity scaling work?

Long term thinking. Natural gas is bad for the environment, along with the massive amounts of C02 it produces. Right now if you can simply put in solar that takes care of all the electricity you need, and then some, you'd be more than carbon neutral and could heat your house for "free".

[@quintonlamport3035]

I watched the video but can't believe it. I do hvac work, a 3 ton heat pump puts out 36,000 btu's of heat at 40 degrees, but as the air gets colder there is less heat in the air and at around 18 degrees you usually have half the heat which would drop the heat output to 18,000 btu's. That house looks at a minimum to need a furnace of around 80,000 btu's. I have a Goodman 5 ton heatpump 16 SEER 2 stage which will keep my house at 70 degrees down to 20 degrees but colder than that the temperature in the house drops. Since propane is currently cheap (99 cents a gallon) I have my system set up to heat with the heat pump down to 30 degrees, colder than than that I switch over to a 120,000 btu furnace.

[@scottc8152]

I have a 24K BTU Senville unit that is rated to heat down to -22F. In use it still provided heat at -35F, but as you say less. I have the same size 1 1/2 story and the 24K unit heats it great, I'll have the house at 78-80F in the winter if I leave it run. Uses 2500 watts full on in winter, so I cycle it on and off depending on if I'm home, and leave the furnace at 67F for base heat when I'm not there.

My big problem with this system, is what do you do for warranties? I'm not sure how you're able to get such great performance at such low temperatures, but if something goes wrong electrically I won't be fixing it for free that's on the customer. Mrcool will have to explain their warranty situation. Are they going to trust the contractors? I would have to see this to believe it with its performance at mine is 24 and still putting out over 90 degree Outlet temperature. My big concern is warranties. Like to know how they are able to make this perform so well at such low temperatures. Before I could ever suggest this to anyone I have to know a lot more about the warranty situation.

Can you calculate the size unit needed for a new build very well insulated ICF house? Also what is the amperage draw when heating and when AC is running. Since we are out in the country there is a potential for extended power loss and want to ensure that the generator can carry the load. I know it can with a propane unit.

Great video thanks for posting. Question: how do these variable speed split systems determine the speed they run at without a “communicating” thermostat that can tell the system what the requested versus actual temperature is? I’d hate to purchase and then realize I don’t get the benefits of dehumidification at slower speeds and the system short cycles instead of ramps down...

[@MrcoolComfort]

The Universal does not need a communicating thermostat to benefit from its variable-speed compressor.

[@davidcameron2366]

So the system isn't able to cycle down automatically with a multi-stage thermostat? It seems like it would be able to anticipate the ability to operate at a more efficient displacement if it, say, had a three stage cool and 3 stage heat thermostat with the ability to have a really tight gap in the stages? (Like heat set to 70, stage one cuts on at 69.7, stage 2 is 69.3, and stage 3 is 68.9?) Or am I completely overthinking it?

[@sprockkets]

It knows the demand via the temperature of the refrigerant returning. As another note, the hydronic cooling and heating system at hotspotenergy also works this way. It senses the return water temp and if demand is non existent, it will turn off. It basically makes sure the water temp is within a certain range.

[@sanity2679]

@@davidcameron2366 youre overthinking it more than likely. the unit if it works anything like a dc inverter split takes the temps of the lines going in and out, uses superheat and varies the compressor if i had to take a shot at it. mini splits it uses temp sensors to throttle the electronic expansion valve and vary speed on compressor. should be same technology.
