Re: [MBZ] Mini split ductless heat pump

2012-12-29 Thread Charles Scruggs
My split system does not do hot water, I have a tankless hot water heater and 
it has been very good.  The hot water heater uses natural gas with electric 
ignition.  The split system heat pump AC works on electricity.  Both very good 
choices.

Ok. Now I know what you guys are talking about. My father installed one years 
ago in a flat in Athens, Greece where I grew up. It was mounted high up near 
the ceiling. Compressor was outside on balcony. We used it for AC. Are these 
that good for heat as well?


The ones from the top manufacturers (Mitsubishi, Fujitsu, Daikin, maybe 
LG,Samsung,Toshiba) with DC compressor motors are. The key phrase is 'inverter 
drive'. Often with oversize compressors, they loaf along during A/C and mild 
weather heating, then go to full power (and sometimes beyond) when it gets 
really cold outside.


My Fuji is AHRI rated to put out 12,000 BTU/hr at 47° ambient but it's capable 
of running from 1700 to 15,000 BTU/hr at that temp. Rated output drops to 8100 
at 17° and 6600 at 5°, I assume max is around 1/4 higher. If you're used to old 
fashioned heat pumps, the fact that it's usable below 17° is a minor miracle.
My house draws about 30,000 BTU/hr when it's 0°F outside, I hope to get that 
down around 24,000, so a single 3/4 ton mini split is just a supplement to the 
furnace like having a fireplace in the living room.


The Hyper Heat Mitsus and the RLS series Fujis are really impressive in heat 
mode when they overdrive the compressor at low ambient temps. I think the MSZ-FE 
Mitsus are a real bargain for heat, unfortunately only available in 3/4 ton and 
1 ton sizes. The comparable Fuji costs 20% more, and the top of the line Daikin 
50% more.

While I really like this unit, the main reason I have it is I snagged it on a no 
reserve ebay auction for less than $1000 delivered.
Before I'd pay $1375 for Fuji's 2nd best, I'd pay $1509 for Mitsubishi's best, 
which is slightly more efficient and puts out even more heat than mine:

http://www.acwholesalers.com/Mitsubishi-Air-Conditioner-Ductless-Mini-Split-p/11975.htm

or $1300 for LG's best, although I can't find any good specs on how it heats at 
low temps:

http://www.acwholesalers.com/LG-Air-Conditioner-Heat-Pump-Ductless-Mini-Split-p/70275.htm

The reason why I'm talking about Fuji's #2 unit instead of their top of the line 
is their top model has internet pricing around $1800 for the 3/4 ton version and 
I can't justify paying 20% more than the cost of Mitsu's best 3/4 ton.

22,000 BTU maximum heat from a "3/4 ton" unit is impressive though.

Electric AC and heat pump combined unit or you can just do AC.  The outdoor 
compressor sends the refrigerant (heaterant?) to the indoor head units which

On demand water heater.  Great for small homes with few demands on concurrent 
water use.  They make about enough to run a shower and the bathroom sink.  Some 
of the larger ones allow you to run a bathroom and use of kitchen sink.  If you 
have two bathrooms, somebody in the kitchen and a washing machine, you will 
want to have two heaters.  Place them close to where demand is and you are 
golden.  Two story homes are good this way.  Put one heater on the main floor 
and you have kitchen and washer covered, upstairs unit does bathrooms so two 
people can shower.

Options are to run electric or gas.  LP works same as natural fuel.  Best to do 
as new construction than retrofit.

Seems like Rich mentioned mini splits in his new addition.
I recently bought Fujitsu's 2nd tier 3/4 ton unit (23 SEER / 11 HSPF) and
finally got it installed and operational this afternoon.

I hung it in the living room, intending to use it like a small wood stove to
make the furnace run less. I also bought a 2nd thermostat for the main 
furnace
so that I could call for heat from my bedroom in the opposite end of the 
house

from the mini split.

After an hour of operation with the mini split set for 74°, the hall 
thermostat
reads 72°. (it's 28°F and sunny outside and the hall t-stat is set for 68°, 
so
no furnace with the mini split running unless I set up the bedroom t-stat). 
It's

interesting how much that little thing can warm my 30x40' house.

Mitch.

Mine's nominally 12k on heat, can ramp up to 15k at 47F.
With temps in the 20s, it took my furnace (28k output on low fire) from 50% duty 
cycle to hasn't run in 3 hours because the t-stat shows 5 degrees above set 
point. Bedroom in the far corner of the house is sitting at the 68° that the 
furnace normally runs at. I think I'm getting close to 14k out of that 3/4 ton 
Fuji with outdoor temps in the 20s (it got up to 29° this afternoon).
With the Fuji set at 80°, it's exactly 80 on the other side of the living room 
from it. Uncomfortably warm, in other words.

Mitch.

Re: [MBZ] Mini split ductless heat pump

2012-12-27 Thread Rich Thomas
I don't know what that means in BTUs but I calculated my addition at 18k -- big 
high space with ~800ft2 plus loft ~400ft2 -- on coldest or hottest day.  36k 
4-head unit (2 9k and 2 12k) that throttles from I think 11k to max.  Should be 
minimal effort most of the time.

Seems like Rich mentioned mini splits in his new addition.
I recently bought Fujitsu's 2nd tier 3/4 ton unit (23 SEER / 11 HSPF) and 
finally got it installed and operational this afternoon.

I hung it in the living room, intending to use it like a small wood stove to 
make the furnace run less. I also bought a 2nd thermostat for the main furnace 
so that I could call for heat from my bedroom in the opposite end of the house 
from the mini split.

After an hour of operation with the mini split set for 74°, the hall thermostat 
reads 72°. (it's 28°F and sunny outside and the hall t-stat is set for 68°, so 
no furnace with the mini split running unless I set up the bedroom t-stat). 
It's interesting how much that little thing can warm my 30x40' house.
