You have seen a ductless mini split before, next time you are in a hotel, stand by the window and look down, the unit there in the wall is a ductless heat pump.   They have come along way and some units blend into the room so well they are virtually invisible.  LG's ArtCool unit uses your favorite picture or mirror as the heat and cooling register.

The BIOS Organization will promote all brands of ductless mini split heat pumps and connect you with local, qualified installers. Hi, my name is Steve Schappert and I have been studying alternative energy for years, I am a building analyst by trade. I have designed and shipped zero energy buildings as far as Germany and I have spent a great deal of time  teaching energy efficiency.  I have taught elementary school students, high school, college classes on sustainable business practices, and recently a 4 hour masters class at Yale  Peabody on Advances in Science Education.

Why I like Ductless Mini Splits:  I learned about ductless mini splits when designing The Bios Center, a 15,000 green living expo. We were going to install geothermal but then I came across some info on ductless mini split heat pumps, the units I was looking at had a SEER rating of 20 and the geothermal was 16.  Geothermal was going to cost $325,000 and the mini splits were only $60,000, honestly it was  a "No Brainer", gas and oil furnaces were about $250,000, standard air heat pumps were $190,000...NOTHING and I mean nothing comes close to the affordability of ductless mini split heat pumps for either installation or operating costs.

The Most Cost Effective Units On The Market For All America

Ductless Mini splits are an excellent choice for all America, they are safe, clean, reliable, affordable and cost effective to operate. When looking at the graph to the left keep in mind that oil has risen to $42 per million BTU from the $32 that is posted here. 

Ductless, mini-split-system heat pumps (mini splits) make good retrofit add-ons to houses with "non-ducted" heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions, where extending or installing distribution ductwork is not feasible.

Like standard air-source heat pumps, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.

Advantages

The main advantages of mini splits are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Since each of the zones will have its own thermostat, you only need to condition that place when someone is there. This will save energy and money.

Ductless mini-split systems are also often easier to install than other types of space conditioning systems. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. Also, most manufacturers of this type of system can provide a variety of lengths of connecting conduits. If necessary, you can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a building house with the compressor in a more advantageous or inconspicuous place on the outside of the building.

Since mini splits have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.

In comparison to other add-on systems, mini splits offer more flexibility in interior design options. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also available. Most indoor units have profiles of about seven inches deep and usually come with sleek, high tech-looking jackets. Many also offer a remote control to make it easier to turn the system on and off when it's positioned high on a wall or suspended from a ceiling.

Split-systems can also help to keep your home safer since there is only a small hole in the wall. Through-the-wall and window mounted room air-conditioners can provide an easy entrance for intruders.
