Re: Issues with Heating in Annapolis, MD

Knowing specifically what system you have is the first step to troubleshooting.

We have a Mermaid 16000btu reverse cycle unit and we used it right up to new years day. The water was in the mid 40s and it continued to pump out warm air and maintain 65 in our cabin although it cycled every 10 minuets. It does not have a supplemental heating coil. We also have an ITU Hurricane II diesel hydronic furnace for the cold days like we are having now.

The other thing you need to properly troubleshoot is an infrared thermometer.

But you must ensure that those through-hulls are not frozen. That can be very dangerous. The fittings can rupture from the expanding ice in them and cause leaks when your boat heels and they submerge.

BTW, this could also simply be a pump relay that is not functioning. We had similar issues with our reverse cycle relay. A good bump would activate it until I could replace it.
