Understanding turndown
Hi I have attached the requested documents:
For example, the Mitsubishi FS06 wall-mounted ductless unit has a rated cooling capacity of 6,000 BTU per hour and goes down to a minimum capacity of 1,700 BTU per hour.  That’s a turndown percentage of 28% (1,700 ÷ 6,000).  If you put that unit in a room with a load of 1,500 BTU per hour, it will bottom out nearly 100% of the time it’s running in cooling mode.


Sometimes you’ll see turndown ratio, which is the same concept as turndown percentage but upside down.  It’s the ratio of maximum to minimum capacity.  For the example here, it would be 6,000 ÷ 1,700 = 3.5.  So the turndown ratio is 3.5 to 1, sometimes written 3.5:1.

What happens at part-load?
One of the great advantages of using mini-splits is their variable capacity.  By oversizing them, you can lose that advantage completely.  That 6,000 BTU per hour mini-split in a room with 1,500 BTU per hour of cooling load doesn’t act at all like it has variable capacity because it’s always running at the lowest capacity except on the really extreme temperature days.
 
When the bottom end of the capacity range is at or above the heating or cooling load, there’s no benefit in part-load conditions.  As the heating or cooling load drops from the design load, you want a system whose capacity also drops.
 
That 6,000 BTU/hr system with a bottom end of 1,700 BTU/hr serving a load of 1,500 BTU/hr doesn’t vary at all in part-load conditions.
 
When the load is 1,500 BTU/hr (the design load), the system will give you 1,700 BTU/hr.  When the load drops to 1,000 BTU/hr, the system will give you 1,700 BTU/hr.  When the load is only 500 BTU/hr, the system will give you 1,700 BTU/hr.
 
Yes, oversizing is a problem
 
So, yes, you absolutely can oversize a mini-split.  And when you do, you end up with some of the same problems you get from oversizing conventional systems:  poor humidity control, short cycling, and wasted money.
 
====air to water heat pump AWHP====
letters to Arctic
 
My use for your '''air to water heat pump products''' will be limited to '''DHW''' and the '''existing kitchen/bath radiant loop'''. That might extend to some kind of wall '''radiant emitters''' for the other two bathrooms depending on calculating the load and the availability of products matching the load. My needs most closely match the following configuration.

I will set up some monitoring on the existing radiant loop for temperature-in and temperature-out which combined with knowing the flow rate should give me the btu/hr load.
 
I am not looking for a "quick estimate". What I need from you is performance and engineering data and pricing on all of listed components.
 
The rest of the house will likely replace 180 degree baseboard emitters with air to air heat pumps connected to some combination of wall units and air handlers.


29 years ago this was a carefully designed system  which heats a 2,700 sf house with high ceilings and lots of windows for ~$1,500/yr @ $2.33/therm. I even got John Siegenthaler to weigh in with some invaluable advice.

With electricity here @ $0.27/kwh and natural gas @ .07/kwh it will be a big challenge to design a replacement system. Whatever it is will have to spend most of its time in the operating range that gives you a COP of ~4 or else the operating cost penalty will be too great.

I am licensed builder in MA with EPA 608 universal lic. and am a member of the MassSave Heat Pump Installer Network. So far I have had very good results replacing oil steam boilers with cold climate heat pumps connected to air handlers delivering heat through exposed spiral ductwork running in the conditioned space. Tenants are spending almost half of what oil cost to run their systems.
