Cold Weather Tests the Limits of Our Mini-Split Heat Pump 

 It’s been quite chilly outside the house, but with mini-split ductless heat pump it warm indoors. Lots of men and women have asked me how our air-source warmth pump is making out in the winter. I published about this system previous fall, prior to we had shifted directly into our new home.

Could it be keeping us warm?

First, if you need to get right up to rate on the shocking and counterintuitive aspect of how an air-source warmth pump works, check out our primer on the topic–which carries a great diagram.

How an air-source warmth pump works?

The inside mini-split ductless heat pump is attached to a wall membrane next to your kitchen, and it’s really been operating very gradually in this winter. (Despite the fact that we’ve warmed with wood for many years and also have all the lumber we could ever before use, I am curious the way the house can do just on electricity, so have refrained from using the real wood stove.)

Monitoring our energy consumption

We’ve a ductless ac installed to keep tabs on the home’s overall electrical power intake as well as the intake of lots of individual tons. The keep an eye on has videos that clamp onto different circuits in the electronic -panel as well as the electrical power main getting into the -panel, and it in some way measures electricity move through those wires. We’re tracking ingestion independently for our warmth pump heat, our heat-pump hot water heater, and our heat-recovery ventilator.

More often than not, the mini-split ductless heat pump has been sketching about 2,500 w, with very short spikes up to about 3,400 w (Perhaps those spikes happen whenever a pump or lover kicks on). To place this in point of view, the two 2,500 w in the typical heating mode is approximately double what our Kitchen Aid toaster pulls (1,200 w), though of course the toaster works for only brief intervals.

Heat syndication with point-source heating

Because mini-split ductless heat pump warmth source is on the downstairs wall structure, I have been very interested how effectively temperature would be sent out throughout our 1,600-square-foot house. The primary kitchen-dining-living space retains a reasonably even temp in the high-60s. A downstairs analysis or visitor room at the far off corner of the home and segregated from heat pump by way of a hallway and entrance doors (with the entranceway open) stays just a little cooler, though enjoying a movie there yesterday evening was fine with a sweater.

Upstairs, the our bedroom on the north part of the home has maintained an amazingly regular 68-70?F on all however the coldest nights.

Bottom line

Overall, we are incredibly content with the air-source warmth pump. It is effective, in large part, because the house is so energy conserving. This is an excellent heat option (and cooling down, incidentally) for a residence with an extremely well-insulated building envelope. After we mount the mini-split ductless temperature pump on the double-hung house windows on the southern and east factors of the home, we have to do slightly better.
