Reverse Cycle Heat

[mmwjr]

No problem just curious

[Johnnyr]

When I ran the system with the valve/petcock open in the engine compartment, I had no water coming out the side of the boat. I need a mechanic to check it out I guess.. Does this look like it has a reverse cycle for heat? I hope the pictures were attached to this thread.

The dials

Nope this is an air conditioning system only, no heat.

The temp setting knob can be confusing as it says warmer but it is just for controlling the AC temp.

A system that provides heat will have settings on the top knob for heat off and AC.

Thanks again for all your help

Can you hear the A/C pump cycle on?

Not that I recall, just the blowers for the fan

right by the petcock should be the pump. is the pump running? If you don't have water coming out the bow port then try this. water should be coming out of that port regardless of the temp setting
loosen the screws slightly until some water starts to come out. This will bleed air out of the pump housing, then tighten back up. do this while the pump is running. I have to do it to mine the first time I use it each year.
I added this unit for heat and it does a fantastic job.it pulls less power than the AC unit.

Yes, you should find the A/C pump back in the engine compartment, along with the sea-strainer and the seacock. On mine, you need to bleed the system manually. If there is no water in the pump or seastrainer, my pump will not auto-prime. I installed a Grocco flush attachment just before the seastrainer. This makes winterization easier as well.

Make sure the boat is in the water, the seacock is open and the system is primed. If it lost prime you would still hear the pump cycle on.

The pump will look like this.

in that picture, those 3-4 small Phillips screws that hold the 2 piece housing together are the ones you can loosen to bleed air out.

Just to clarify this will get the air conditioning working but the OP does not have reverse cycle heat as the threads title states. i.e. no heat only A/C.

Yes I'm aware he doesn't have heat but if no water is coming out the bow port than its either clogged screen, air pocket, or bad pump. Basically the unit isn't operating.
For heat I added one of those Broan in wall electric heaters with a small blower inside. Warms cabin up quick.
Uses less electric and ac.

My message was directly to you alone but to shrew and the OP as well. The OP seemed certain he had heat and with folks trying to help resolve the lack of water flow I did not want him to get confused you were trying to help get heat.

I 'think' we're all on the same page. Initial issue was about heat. thread drift was introduce about not pumping or discharging ANY water. (Or so I thought).

Sorry everyone for the confusion, I just had my gallbladder taken out and a hernia fixed, so I'm laid up for a week or so. So I will bleed the system out when I get to the boat. Again I'm sorry the thread drifted. I'll let you all know how it works, that should take care of it, my fingers are crossed.

No reason to be sorry just wanted to make sure you were not confused.

Hope you heal well soon. Relax and get healthly for the up coming season.
