SM heat


Mike Ondra
 

I can confirm that the heat works without the water pump circulating. Will sleep warm to night. Thank you all.

Hi Mike,

If you have electric coil heating on your units, the water flow should not run.

If you have reverse cycle heating and air, the salt water pump should only run when one the compressors is running on one or more of the three units.


With best regards,

Quick question. In the SM circa 1999, water is pumped through the three air handling units in both cooling and heating mode even though the heating mode is resistance. Is there a way, or would it be imprudent, too turn off the water pump when in heat mode. Would it be reasonable to install a switch on the water pump circuit to avoid circulating water when it’s not needed.

Hi Mike,
I believe on Kimberlite the water pump only runs when the compressor is on. I would check it on your boat.
Unfortunately I am not on Kimberlite at the moment.

Hello Mike,

in the SM2000 (starting october 1998), the A/C compact units compressors are cooled with seawater. The pump starts whenever one of the units is turned on cooling mode.
But when these A/C units are turned on heating mode (as you mention, heat comes from a resistance), then the seawater pump does not run, and seawater is not running through the circuit.

Olivier.
