Hydronic heat without fan

I know this has been answered before but I can't seem to find it, what is the proper procedure for running the hydronic heat (circulating hot water through the coils) without the fans on. I would like to do this at night to keep the chill off without the fans is this possible and does it work?

What system do you have?

I would like to hear how this is possible also. The fans are very loud and wake me up.

On the Oasis there is a pump switch that turns the pumps on continuous for testing.

I don't think this would heat the coach much at all just using convection. Now if the coils were large and above floor level....similar to the steam radiators used to heat houses...it might work ok.

If you have the type of heated tile floors which use the AquaHot, then this would be an option.

I believe in the Hydra Hot system, the circulating pumps call to operate by zone is thru the comfort thermostat (probably a Dometic that also controls heat pumps/ac, etc.). In my 2005 MADP I can only opt out on the fans running on the dash coil that give extra heat around the windshield area. All other fan coils are controlled by the temp thermostat on that particular coil. For example, you set your comfort t-stat for zone two heating and when each coil in that zone reaches the cut-in temp of the t-stat mounted on that coil (to keep it from blowing cold air), then it turns that fan on. Same for zone one except the very front coil "FAN" (coil is still heated by circulating water) is controlled by a separate fan switch that must be turned on to have heat in the very forward windshield area (usually has hi, off and low positions).

Sorry about that it is an Oasis.

pasdad1 you are probably right but I want to try something because it does wake me up all night.

I tried putting a rheostat on one but the motor made a bad whining noise when the speed was turned down.

Check out this thread. Another user took apart the heat exchanger and apparently there is the possibility of replacing noisy motors with other motors that are nearly silent. Might be an option.

I just leave Zone 1 on at night and leave Zone 2 (bedroom) off at night. You could always try earplugs!

Well, if you are connected to shore power, put a heater like this one in your bedroom, they emit no light, and are totally silent (no fans at all). Very safe. They never get hot enough to ignite any flammable material.

I only boondock never really hooked to any power. But I appreciate your help great ideas.

Funny you mention that heater I used one while living in my trailer while building my house and was blown away at the very high electric bill.

Seems like it would be easy enough to wire in a toggle switch which would cut power to the fan motor when desired. Sounds like just need to do the one heat exchanger in the sleeping area.

For years we have only ran the front a/c at night because of noise. The last time out with the Oasis we ran the heat in the front only at night. It helps with the noise but I still hear them run. The Oasis does already have the muffin fans installed, but with two on each heat exchanger they make a lot of noise. The back zone is always warmer due to smaller area and less glass. I also run a small fan in the bedroom for white noise at night, even when boon docking.

The hot water circulates anytime the thermostat is set above 50. Yes they make some noise but far less than my old forced air furnace in last rig. We like the bedroom cool so the only one running at night is the front .

To run the pumps, means making them run full time. You must turn them on and off from outside, it overrides the thermostat.

It the switch on the top of the silver box beside the Oasis.
