Looking for a small fan coil unit

DCContrarian

I have a hydronic system that does both heating and cooling. There is a small room that I would like to put on its own thermostat. I've done a room-by-room Manual J and the heating load for that room is 1500 BTU/hr and the cooling load is 2100 BTU/hr. So I'm looking for a very small fan coil unit to handle both heating and cooling.

There seems to be almost nothing on the market that comes close. The Chiltrix CXI34 (https://www.chiltrix.com/chiller-fan-coil.html ) is rated for 3,379 BTU/hr cooling and 3,013 BTU/hr heating which seems about right-sized, but I'm not thrilled by the looks. Several other sellers seem to have similar units that may be rebadged from the same manufacturers.

Ideally I'd like something I could conceal or dress up somehow. I know there are recessed units by Myson and Turbonics, which would be perfect, but so far I've only been able to find ones that are heating only, no cooling.

Any thoughts?

Thanks, some quick Googling shows that's along the lines of what I'm thinking of in terms of form factor and capacity. I haven't found anything that works hydronically yet.

And they seem to charge a premium for them!

Take a look at Multi-Aqua

Thanks. I hadn't looked at them.

They have a 9000 BTU unit but it's heating only, their smallest unit that does cooling is the CFFWA or the MH1WC4W, both at 12,000 BTU. The CFFWA seems basically comparable to the Chiltrix but it's physically larger and the Chiltrix comes as small as 3000 BTU. The MH1WC4W seems like it's similar to a Midea MKC. The MKC isn't distributed in the US as far as I know but I've been able to buy a couple of them off of Alibaba.

I like the MKC, it mounts concealed in the ceiling and it's only 6" thick. It does require 24" joist spacing which won't work in this application (although I suppose I could build a soffit for it). It's rated 3 kW which is just over 10,000 BTU/hr.

I'd like to get something that's fairly close to the room loads in terms of capacity. I know it will work oversized but I'd rather not have it cycle constantly.

I would contact them and find if they have conversion charts based upon different water temps to get closer to your capacity needed.....ahhh the beauty of hydronics..... and then get the water temps to modulate to minimize the short cycling
