we would like to purchase a dual zone ductless mini split to service our bedroom (300sf) and sun room (300sf) . Wiil a 9000 btu unit be sufficient?

Yes. Select one 9000 BTU Indoor unit for the bedroom and a 12000 BTU Indoor unit for the sun room. On a dual system for best matching.

Two units parallell should. I run a 13,500 BTU which is 115VAC and run my microwave and all the lights at the same time with two unit parallel. A 15,000 BTU runs a 115VAC. The 15K needs to handle a power surge of up to 3600 watts. Which is within range of the Champion pararrel ported. Family Motor Home (FMCA) magazine states the following: 2.5 kw generator can power a single 13,500 BTU a/c 3.5 kw generator can power a single 15,000 BTU a/c 4 kw generator can power two 11,000 BTU a/c's 5 kw generator can power two 15,000 BTU a/c's

Yes the indoor unit needs to be centrally located to reach all areas with similar effect. You also need a 24000 BTU unit.

I have this unit for a few years, and I am very happy with it. It is not a dual zone system. Only one indoor unit.

I have a 2000 sq. ft. house. It does all but the back two bedrooms (about 1700 sq. feet effectively), but that is more of a wall / air flow limitation. I would say about 1500 sq. feet is the ideal for the unit, but you can effectively get up to 2000+ sq. feet depending upon layout / air flow limitations. That is with ozone. I have tried similiar units, and for what it does, this is a great value for the money, regardless of size space.

I purchased this AC for our 20 x 25 bedroom. I keep the temperature on 74 to 76 degrees and it keeps the room cool. I'm very happy with the quality and it's ability to keep our bedroom cool. I've never heard the rule of buying an AC 4000 BTUs larger than you think you need. I hope this was of help to you.

All heters are the same really. 1500 watts is 5000 BTUs and it doesn't matter much after that. 13x14 worked fine for me but it depends on house insulation, and outside temperature. It was also supplemental, as the centeral heater was holding the rest of the house at 63.

In considering the size AC unit you need, the first thing to look at is the climatic region of the country in which you will use the system. If you are on the same latitude as Burlington NC our summer design is approx. 92 Deg. F. So it is considered middle of the road for the design of most units. We actually have a high humidity issue occasionally. The next thing to consider is the amount of radiant energy the room is exposed to, which you could call the solar(sun) exposure, first the total of perimeter walls in square footage and then the amount of glazing(window) square feet, as well as the R value rating of the windows. Next is the ceiling height, because with the mini-split units they are installed within 12 inches of the ceiling. To help you get a more practical overview. All these things will help you determine if you can stay with the basic manufacturers room size rating or have to get a little larger unit. Watch this video to help you get a better understanding of unit selection: http://www.youtube.com/watch?v=fYHCc0DeDwA. Good luck. DCW

Its fine for DIY. Cut 2 sheet metal holes for the ducts and run wire for the low voltage line plus a water line. It was about 4 hours for me, probably 2 hours for a pro. Capacity is hard to judge, I have a 2500 sq ft house in a very dry area (desert) and in mid winter I need to leave the furnace fan "on" to keep the humidity up. If it only runs when the furnace is on, then it can't keep up.

Not sure but I installed it on my motorhome that has a 42000 BTU furnace, a fridge, stove, and hot water heater and it will service all them at the same time. Not had a problem since I installed it for lack of fuel..

It's rated at 18000 btu, does a great job. I installed this unit in an uninsulated race trailer on a 20 amp circuit with no issue. It is easily ran by a 3000 watt generator. Great air flow

Dear Valued Customer, The cooling Btu of this system is roughly 60,000 Btu's. The Btu's coincide with the size of the system. Residential systems do not exceed this size. Please keep in mind this system does not offer heating, this is an air conditioning system. Heating elements can be added as an accessory. Please contact our Sales Office for further assistance with your inquiry at 888.474.9966 during normal business hours EST. Sincerely, The AC Outlet Amazon Team

I think this fixture is more appropriate for providing light, specifically full spectrum, as opposed to heat. I believe it has a rather low total wattage that can be used, 25 watts on each side. So I don't think you would need two, unless of course you want a lot of light. The CF are nice as they provide full spectrum (UVB) in a compact bulb, eliminating the need for larger fluorescent bulbs. There are not any incandescent bulbs that put out UVB to my knowledge, but they put out a good amount of heat. The CF bulbs are nice as they are lower wattage so less energy. I believe lower heat but they're not really used for heat bulbs in reptiles anyways. I think this fixture is more appropriate for providing light, specifically full spectrum, as opposed to heat.

That depends on the amp draw of the unit and at what voltage 110 or 220, if it is more that 14.5 amps then I would say no. Why I say 14.5 amps is because even though the unit is capable of outputting 29+ amps. (3250 watts divided by 110 volts = 29.5 amps total, 14.5 each side at 110 volts), that is for each side or leg of the unit, each hot lead to common. That is why it is important if you have it connected to a breaker box to even off the load of each side. A 5,000 BTU home AC draws approx 5 amps, so if your AC unit is pretty new and efficient then there should be no problem. Hope this helps.

Assuming that is 25' x 25' x 10', I believe 1 unit would be challenged if you're in Northern Alberta - checking some weather info for Fort McMurray (a guess), I see 'average' lows of -10 F and minimum lows of -30 F over the last 20 years (and -58 F for the long-term). I set mine at 45 F for a 24' x 30' x10' (12' roof peak) metal building (not that well insulated) in Texas and with +8 F ambients, it was on 45 minutes/off 15. I did buy 2 but only put 1 in service, as that was acceptable to me. Also, there are recommended minimum clearances of 34" top and 68" below for these units; a 10' ceiling and a 12" unit height means you're almost at minimums (34" + 12" + 68" = 114" = 9'-6") to start. With the radiant heat flux off these units, the area directly below (or directly facing if you mount the unit at an angle, as I did) will get hot, so depending on what you're using the space for, there may be issues with localized 'hot spots'. Having a method to keep the air in the building/room well-distributed is also important (I used 2 ceiling fans) for several reason. The unit will consume O2 out of the air - about 1 cubic foot of O2 per minute. There is a recommended fresh air flow in of 160 CFM for this heater (high, IMO as a Chemical Engineer, but I'd want at least 50 CFM), so proper ventilation is also a concern if your room/building is 'tight'. You can better evaluate your specific application, but I believe one 40,000 BTU/Hr unit would be marginal in that size building (unless very well insulated) in the climate I think you're looking at.

You need the ductless version. The ac comes with the ceiling mounted controller. The heater requires an additional heat strip
