R31 to much heat in the stateroom forward cabin

[Mr.TL]

Enjoying the comfort of my RT heater, which works great! However, I've noticed that the forward cabin tends to get about 15-20 degrees hotter than the galley/dinette area. I'm wondering if anyone has come up with a solution to direct more heat into the galley.

If you have any tips or modifications that have worked for you, I would love to hear about them!

I am assuming you have this problem when running you AC/Heat Pump. On our R31 for both Cool and Heat we make sure we close the door to the forward cabin. Also raise up the port seat to allow the heat or co in the main cabin to rise.
We have also on occasion placed a 12V fan near the helm to blow air aft.

I hope this helps.

Thanks - This is a northwest addition in the PNW. It does not have AC/heat pump. It's a diesel heater. The only issue is closing the forward cabin door because it pumps so much heat out of that vent down by the door. It will make that forward cabin even worse and cause less circulation within the boat. Good call on port seat forgot if there is a vent down there. I was thinking of modifying the forward cabin vent by either taping off some of it behind the vent to restrict output or a small damper in the tubing, but I am not so sure if a diesel heater should be restricting flow as they don't make the vents to close only to rotate direction of air flow. Thanks again for some thoughts on it.

on my R29 the issue is the thermostat is right by the cockpit door. I got the Webasto remote so I can control the temp from bed, but that makes the galley cold.

I replaced the vberth heat outlet with one that can be adjusted (we close it down to 1/2 and that helped some) I added a wye to the ducting to add heat outlet in the head. I found a wire not connected on the Webasto heater which caused the heater to go by bilge air temp instead of the controller thermostat.
I will be connecting a cold air return from the Webasto to the foot of the mid berth next week. That should also help pull warm air through the cabin.
Every bit helps to reduce the veberth temp.
We also only set the temp to 58 degrees when sleeping. It still ends up warmer than that.

We also replaced the controller with the Bluetooth version which allows us to adjust from bed.

Thanks - I really like the Y idea. I have never looked at routing, but I have an R31, so I'm unsure exactly where I would want to cut into the wet head even. I only turn it on morning or evening etc., not while sleeping; the issue is say when one of us gets up early and turns it on, pumps heat into the forward cabin like crazy. The return I believe on my boat is in the cave (mid-berth) way in the back, so getting another one would be a great idea.

Maybe your boat is newer but ours is a 2021. There is no factory cold air return

Put a hair dryer on low heat near your thermostat. If temperature increases on thermostat, then sensor is probably at thermostat. If not your sensor wire at heater unit may be unplugged. I think many Rangers had that unplugged, leading to controlling heat based on bilge temperature. The air intake is in bilge. This is shooting yourself in the foot and heater temperature will never be accurate. I spent a day to move thermostat to forward berth doorway. Not a fun day fishing and pulling wire. Not for the light hearted captain. My issue, how do you sleep with a noisy Webasto????
Mine is 2017 R29 with a smart 3.0 webasto upgrade. I just compared my noise level to a month old R29 and it is the same level.
Temp sensor unplugged is default from Webasto since it may be appropriate for some boats or vehicles to control temp at heater unit.

Thanks - Although the issue is not the thermostat control, it is fine; we do not sleep with the heater on. The concern is, as an example, we are a couple boating together. One gets up in the morning prior to the other person turning the heat on. The v-berth cabin supply is way more volume, creating much more heat in that enclosed area versus the galley and dining area (not very well balanced). Or someone is in the v-berth reading, doing some work, etc., and one person is in the galley, and it's twice as hot in the v-berth cabin. I'll probably try the suggestion above the Webasto grill that can open and close, just hoping it the right size as I believe the grill is larger in the v-berth cabin than the rest.

Calling my Webasto controls 'thermostats' is a huge stretch as they are astonishingly inaccurate. I always suspected that the sensors are placed in an area that is always cold. The solution for me was to turn it off at night and use a small space heater that is more than adequate and completely quiet for night time temps...although, I'm in CA, not WA.

The adjustable vent listed above is the correct on for the vberth on the R31. It’s available at Sure Marine in Seattle. We used the same one on our boat.

Awsome - Thanks for the help and clarification much appreciated!
