What's painful is that I've dropped $9k on a 5 Ton chiller with all the bells n whistles and it's not here yet! Next week, I'm promised.
Then, it too will shed plenty of heat, this time into a hot water system that I can use to keep my home comfortable.
I'm expecting a record hot summer this year, so I will be prepared. Are y'all ready for the hottest summer EVER?

i recently started running my stuff at night to try and keep everything in balance. works great for me cause temps in the daytime can get up to 95F=/
I'm excited to see what you do with COBs=]]]

It has hot gas recovery, which means it sheds heat first into a hot water circuit. It then flows around my house just like hot water baseboard heat would. If this water system gets hot enough that it won't take any additional heat, the chiller will reject the excess into the air. Yes it's mounted outside, just like a heat pump.
In fact, you can think of it as a heat pump, only instead of reversing flow to go from cooling to hearing, it just has two circuits that handle cold and hot separately, full time. The two water circuits allow me to run each room individually on their own thermostats.

Balance, indeed!
I run a flip schedule, this allows me to have half the heating and cooling capacity I'd otherwise require. Separate heating and cooling circuits allow me to heat and cool any space, any time, independent of other spaces or the time of day.
The COB LED system is playing its part by converting watts to PAR more efficiently than its predecessors. So far, they have NOT produced a substantially different load on my cooling system, very likely because they're pulling exactly the same watts.

Sounds like a pretty fancy chiller. Didnt know you could get a chiller with heat recovery.
Will you still need a furnace or will the chiller recover enough heat to replace it?

I spent the extra $100 or so for a 1kW electric heat strip in the cold water system. This will guarantee that even if there's no outside load on the chiller it will still drive enough heat to the hot side to guarantee home heating.
It makes 5 Tons of cooling- plus 10%- at 90F ambient. While doing so, it makes 7.5 Tons of heat, plenty of heating for any three normally sized suburban homes in Colorado.
I threw my old furnace away last November, even before the chiller got here. My window banger based 2 Ton unit has been plenty to keep my house warm (even TOO warm!) for the last 4 winters.
The difference will be that the hot water system will be on a thermostat, where up 'til now I've had to manipulate fan settings and such to maintain comfortable temps in the house.

It's two separate circuits, so no valves. The hot water side will still come in handy for heating rooms overnight and dehuey, as well as shedding excess heat from other systems, like water cooled co2 burners. All excess heat gets shed outside, regardless of the season. Pretty darn nifty, and since it's using heat I've already paid for and paid again to move, I don't have to pay for it yet again!

Yes but wouldnt you want to shut down the recovery side completly in the summer? Meaning why have hot water circulating through your house and adding to the heat load your trying to remove...or am I not understanding?

We've installed the hot side manifold, bought the baseboard heaters and the chiller comes with tanks and pumps for both hot and cold side circuits.

The heat load won't be that much because the heat stays in the water system.
Everything that needs heat will be on a thermostat, which will control a valve on that circuit. This includes the water to air heat exchange core I'll use for heating the house; this home was built with a gas furnace and forced air heating. I'll use the existing ductwork to circulate air upstairs in the living space, the heat exchange core will sit in the system where the furnace used to.

No, Sir; fewer moving parts, just better integration with HVAC systems as opposed to the common scenario of treating building HVAC and growroom needs as if they're completely separate.
I no longer have a furnace AND an AC plant; they'll now be integrated, with the ability to gain serious efficiencies and thus reduce costs along the way.
In fact, I'll have just one compressor handling everything that requires heating, cooling or dehuey in the whole house, period.
