BC: DUCTLESS AIR SOURCE HEAT PUMPS .. .. .. . . . . .. . . . . . . . .. . . . . . . As many of you know, I've been a vocal advocate of ductless heat pump technology and I think they're a great option for those of us who heat with oil. A friend of mine in Prince Edward Island installed a three zone mini-split in his century old farm home two years ago and it reportedly supplies "99.9%" of his home's space heating needs. He estimates its annual operating costs at $700.00 and that it has reduced his fuel oil consumption by some $3,000.00 a year, a net reduction of just over 75 per cent (bear in mind that PEI has the highest electricity rates in Canada and some of the highest in North America). ======= Our Sanyo 12KHS71 is a 115-volt inverter unit (http://us.sanyo.com/HVAC-Single-Split-Systems-Wall-Mounted-Heat-Pumps/Wa...) which allows us to monitor its energy usage with a standard Kill-a-Watt device. It's a 17.0 SEER/9.3 HSPF model which makes it a pretty decent performer vis-à-vis a conventional split system. However, the Fujitsu 12RLS at 25.0 SEER/12.0 HSPF (http://www.fujitsugeneral.com/wallmounted9-12RLS_specs.htm#specs) is unquestionably the gold standard in energy efficiency and well worth the price premium. I'd highly recommend the Sanyo if you're limited to just 115-volts, but if you can possibly swing 230, the Fujitsu can't be beat. ======== The current generation 12KHS71 provides a good amount of heat even when outdoor temperatures fall sharply; for example, at -18°C/0°F, the 12KHS71 still cranks out a little over 2.3 kW of heat or about the same amount of heat as would be supplied by a 10 ft. electric baseboard strip. Our Sanyo serves all of our lower level -- approximately 90 m2 with an uninsulated slab and wall-to-wall, floor to ceiling north facing glass -- and it has no problem keeping up. It's an amazing performer and I highly recommend it to anyone looking for a 15-amp/115-volt unit. =========
