Another unsung feature of the mini split is setting them to "fan" mode for when the temps are hot but not so bad you want to run the AC or when the stove has the room over heating for your tastes and you just want to get some air moved around. The technology really is pretty impressive. Canadian border VT is the brand you're looking at "Mr. Cool"? I've heard really good things about those systems from the guy that installed the system at my house. I did not go the Mr. Cool route only b/c we got a discount going through his company.
RGrant not Mr cool; I think it’s diahatsu much more common in Europe Vermont state efficiency program just doubled rebates. Checking to see if on list Friends who are snow birds love their Mr cool but not for our negative temps but down to 10 above yes
I have a ductless mini split at the office that runs 5 separate heads. Does a fantastic job, works great even when it was -22. The new heat pump I bought works good but I’m not thrilled with it so far.
Once I started WFH, AC better than my 6k btu and portable 12k btu units became a necessity. Because of the sun exposure on the west side, even going full tilt there were many days that it was 80* or more. Then the house would not cool off overnight by but a couple degrees. That is the whole reason I got the MS - didn't even realize it could heat too until I started looking at what other people were discussing. I love having 3 heating options. My main floor has MS, pellet stove and FHW. I can pick and choose although I could do without the boiler - right up to the point that I get decrepit enough that moving pellets from the basement up stairs becomes untenable during the really cold spells. Basement only has the pellet stove, although it will get residual heat from the FHW pipes, which is enough to keep it above freezing.
You deserve it. Redundancy, if it's good enough for NASA, it's good enough for me. I can heat with wood, oil or electricity. Winter be dammed. Cooling, my choices are limited to one. But it's a great one! Getting some of your tax dollars back is always a bonus.
Just ask savemoney . His stove is down but his other options (link goes to the Pellet Heads thread) are keeping him warm during this cold snap.
My investment was really almost nothing. With rebates and other gov. giveaways, I started getting my return right from the beginning.
savemoney I had a bid done for 2 Mitsubishi mini splits at my house over summer; after all rebates etc was 10 thousand 12 k btu head level 4 18 k btu head level 3 That’s why I was waiting; then flood happened on investment property and 5 thousand was deductible So still saving & waiting…
Anyone have a recommendation for a thermostat? Needing one for my heat pump. Must have dual fuel, two stage heat and cool and be either WiFi or outdoor thermometer compatible. Additionally it needs to be adjustable for setting when different stages are activated.
Sorry this is so late- I didn't see an alert for this thread- but I can say maybe 3 things. 1st- my thermostat is programmable and I have a few settings I changed around, but for temp settings I manually change them. 2nd- when I was driving a truck for an HVAC company out here one summer they stocked Honeywell and said they were the best 3rd- I just looked this up and: Honeywell still ranks great. The brand we run is Daikin for disclosure's sake.
Got a few minutes to add this: the settings I changed were a) for cooling I have it set to have the fan run constantly even if it isn’t calling for cooling so the moving and circulating air feels cool on the skin, and b) for the exact same rationale, I have the fan only run when calling for heat so it doesn’t have that perception of cooling. Regarding temps we are all over the place even though most advice you’ll find says find a temp you like and just leave it.
The main issue I’m having is if the outdoor temp is near freezing after 90 minutes run time heat pump runs a defrost cycle. Defrost is basically running the AC. What I want/need is the ability to bypass stage 1 when temp is below 38 degrees. Stage 1 will maintain temp but what happens is it times out, runs a defrost cycle which drops temp enough that propane kicks on to bring house back up to temp. Running exclusively in stage 2 below 36-38* will decrease my run time and propane use. I really like my current thermostat except for this one issue.
When you get a chance can you post the units you're running and the thermostat make & model you have currently?
To configure your Pro1IAQ T855 thermostat to utilize the heat pump above 38°F and switch to propane heat below that temperature, follow these steps: Access Technician Setup Menu: Press the MENU button on the thermostat. Press and hold the TECH button for approximately 3 seconds to enter the technician setup menu. Enable Dual Fuel Mode: Navigate through the settings until you find the "DUAL FUEL" option. Use the arrow keys to set this option to ON. This setting allows the system to switch between the heat pump and auxiliary heat sources like propane. Set the Balance Point Temperature: Continue navigating until you reach the "BALANCE POINT" setting. Use the arrow keys to adjust the balance point to 38°F. This temperature determines the threshold below which the system will switch from the heat pump to propane heat. Finalize and Exit: Press the DONE button to save your settings and exit the technician setup menu. Please note that an outdoor temperature sensor must be installed and properly connected to the thermostat for the balance point feature to function correctly. This sensor monitors the external temperature, enabling the thermostat to switch between the heat pump and propane heat based on your specified threshold. For detailed information and additional settings, refer to the Pro1IAQ T855 Thermostat Installation Manual.
Don’t have a balance point option on my thermostat. Either the outside thermometer is not set up or not installed properly. HVAC tech was supposed to install it.
