Just picked up a ClimateMaster GSHP

Geo NR Gee · 04-27-11, 12:50 AM

I stumbled onto a 4 ton ClimateMaster GSHP for $250. It was used in a office building for about a 1 year and a half to cool computers. The business moved and the unit didn't. Now the fun part of planning the ground loop.

I also need to find a pump setup and manuals, etc.

What a total score!

I assume you're gonna do trenches & slinkies...

Don't try to short-change the heat pump, regarding your ground loop, you'll just end up freezing the ground, & maybe the water in the loops.

...if anything, put in more loop than you think you'll need, you really can't have too much loop.

You're a lucky guy.

Good luck,

Woohoo!
Great find

killer deal man.
i talked to an ac shop today and he can sell me the base model climate master gshp 2 ton unit for around $1300 + tax then the one with the 2 stage compressor is around $4000

but still way better deals than online

Thank you for your comments. Seems though the easy part was putting the money in the guys hand.

4 tons is more than we need, so it looks like we will be heating and cooling the garage and the patio too. It also comes with a better computer board but does not come with the option to heat the hot water tank.

is it the two stage compressor with variable speed blower if its two stage it will run on the first stage which is 60% of compacity

Rhino 660, I am not 100% sure that it is or is not a two stage compressor, only that it says reciprocating with a three speed fan and the following I found below:

Option: Enhanced solid state control system (DXM)
This control system features two stage control of cooling and two stage control of heating modes for exacting temperature and
dehumidification purposes.
This control system coupled with a multi-stage thermostat will better dehumidify room air by automatically running the heat
pump’s fan at lower speed on the first stage of cooling thereby implementing low sensible heat ratio cooling. On the need for
higher cooling performance the system will activate the second stage of cooling and automatically switch the fan to the higher
fan speed setting. This system may be further enhanced with a humidistat. Units not having automatic low sensible heat ratio
cooling will not be accepted; as an alternate a hot gas reheat coil may be provided with control system for automatic activation.
Control shall have all of the above mentioned features of the CXM control system along with the following expanded features:
a. Removable thermostat connector.
b. Night setback control.
c. Random start on return from night setback.
d. Minimized reversing valve operation (Unit control logic shall only switch the reversing valve when cooling is demanded for
the fi rst time. The reversing valve shall be held in this position until the fi rst call for heating, ensuring quiet operation and
increased valve life.).
e. Override temperature control with 2-hour timer for room occupant to override setback temperature at
the thermostat.
f. Dry contact night setback output for digital night setback thermostats.
g. Ability to work with heat pump or heat/cool (Y, W) type thermostats.
h. Ability to work with heat pump thermostats using O or B reversing valve control.
i. Emergency shutdown contacts.
j. Boilerless system heat control at low loop water temperature.
k. Ability to allow up to 3 units to be controlled by one thermostat.
l. Relay to operate an external damper.
m. Ability to automatically change fan speed from multistage thermostat.
n. Relay to start system pump.
o. 75 VA control transformer. Control transformer shall have load side short circuit and overload protection via a built in
circuit breaker.

Very nice find there. I am installing the ground loops for my brother's system next week, over in Yakima. It is a ClimateMaster as well.
I am a heavy equipment operator by trade and have good access to equipment through my employer.

Your brother is lucky. Digging the trenches is like half the battle. I wish we had property to dig trenches.

I was thinking about the line set install and whether we should have a sight glass installed? Do others think its worth the money? The line set has not been installed, so now seems like the time to put one in. Would there be anything else that could or should go inline, like maybe some where to attach a line temperature sensor?
