What size bilge heater

I've been indoor rack stored the last 4 winters, this winter the boat will be in a boat house. The temps usually only dip into the low 20's for a short period of time some winters it has stayed freezing for maybe 1 to 2 weeks. I was out on the boat the other day & measured the bilge it's approximately 140 cubic feet with a single 5.7l and FWC.

I've looked at numerous websites including BOE none of the heaters really give any specs of what size bilge they'll protect, one site said it would protect a bilge 340 cubic feet at -4* none of the rest seem to give much info on sizing.

I'm leaning towards the Boatsafe Jr-600W or the Boatsafe Minimax 600W from BOE or the Twin Hornet 35 600W. Possibly the Caframo Pali 400W.

Anyone have any thoughts or recommendations or how to size a bilge heater I'd rather be over sized than save a couple bucks. I like the idea of the Hornet having dual switches & fans if one fails the other one keeps the heater running.

Mold can be a problem with too much cabin heat as it will cause condensation.
Winter boating can be fun but it is cold, damp and survival if you fall over board is short.
Thanks for the info.

In the cabin I have a Caframo True North Model 9206CABBX for heat on anti freeze mode setting 1. The anti-freeze setting is a great winter storage solution that automatically turns on when the weather drops to 38° F ( 3°C), ensuring the air temperature in the room remains above the freezing point.

With a Caframo Stor-Dry Model 9406CAABX dehumidifier combats mold, mildew and musty odors in any boat or RV that is closed up or winterized. This dual action air dryer uses a low wattage heating element and internal fan to both heat and circulate the air. The heat and circulation prevents stale air pockets which in turn prevents mold or mildew forming on the interior surface of the boat.

I've been boating in the PNW since I was 3 years old if I die at sea well I'll die where I love being.

By boat house do you mean in the water? I used to leave my boat in the water in Nanaimo all winter. All I did was turn off the fresh water pump, open the taps, put 2 pan 100 watt heaters in the cabin and leave. It got below freezing for a few days each winter and we had ice on the water some times. The only thing that ever froze was the carbon water filter for the ice maker.
Yep in a boat house in the water, we boat year around plan on just emptying the fresh water with a Caframo True North heater in the cabin set to freeze mode it will come on at 38* and keep it above that temp. If we have an extended period of freezing I'll set the cabin heater to a higher setting to keep it about 50*. The bilge heater will run till it reaches 58* .

I am also considering having my canvas guy make some covers for the ER vents out of black sunbrella to match the new camper canvas....they will be held in place with snaps.....this will help keep the cold wind from blowing in the vent.....

I like that idea we have a canvas shop across from our marina I'm going to have a pair made to match, plus I'll be able to remember to remove them when we take the canvas off to go out.
