Re: Dehumidifier in wet/rain PNW?

I'd think you'd need to get the humidity down to 60% or so, before you start feeling better, and have drier living conditions.

I wonder if that unit can get it down that low with 4 people breathing in there, to say nothing of cooking. Maybe if you combine better ventilation with the dehumidifier?

Re: Dehumidifier in wet/rain PNW?

So the numbers in the morning are almost 1 cup or water in the machine, about 87% humidity, which the fact that it went down, not staying the same or up, gives me hope.

I've stayed around 60 percent. As an experiment I turned mine off a week ago. I'm over 80 percent again. I think it will take a lot to get the humidity down to start, but keeping it lower is easier.

Edit:I had to install a real dehumidifier this week in a boat that leaked. It is pulling an amazing amount of water, 20liters a day I think(3 full tanks).
Totally different, it's pulled the boat down to 60 when combined with a big blower.
Overkill for me, but I might try it in my boat once we're done, just to pull me back down before I turn on the small quiet one again.

Re: Dehumidifier in wet/rain PNW?

This is really encouraging. We have a regular household unit from Home Depot, just two aboard, breathing and cooking and all. Heating the air dries it out some and helps, but still, we often pull out a quart a day in our 33-footer in Maryland.

I'd love it if we could find something more space efficient than our current unit, if it worked.

Re: Dehumidifier in wet/rain PNW?

When I restart my dehumidifier for the fall season it tends to fill up in a week, but 2 weeks like that it seems to go into 'maintenance mode' where the water recovered is much reduced, often going a month before needing to be emptied. We do put a bit of heat on board to prevent the dehu from freezing up.

Keep in mind, everyone, that heat doesn't really 'dry things out' directly.. warm air can actually support more humidity than cool.. it just stays in the air as opposed to condensing. For example warm air against a really cold window really gets to be 'dripping' because of the available moisture in the warm air.

So what kind of dehumidifier is this??? We are going to be going out of town for a few days and I wonder if it would be possible to rent something like this to put in while we are gone? Assuming that it would you know, fit in our hatch, not blow the circuits, and that I could move it by myself. I was thinking of calling the local 'tool rental companies' in town to see if they might have something.

Harbor Freight Tools has the inter-locking foam anti-fatigue mats fairly cheap. A pkg of 4 is just $9.99. Black only, though....

65 pint from home depot. I'd get the smaller one, this was urgent, and combined with a blower.
I got the premier brand one. 3 reasons over lg. Either will do, both have house fittings to drain to bilge.
1 has a decent handle
2I like that air goes in the front and out the top.
3 double the warranty length.

Rental was the same as buying after a week or two. Never understood adding heat and just moving air around in a sealed boat.

In my home and garage I have had 4 or 5 dehumidifiers and I think the warranty is a big issue. It seems to me that the new electronically controlled units are not nearly as reliable. I had an old one that seemed to be work for ever. The newer ones seem to have controllers go out. If I were to buy another one, I would get the extended warranty as I have not seen a new style last more than a year or two. I like the idea of Sears as they actually have service centers locally.

Re: Dehumidifier in wet/rain PNW?

I think this is the one a couple of friends put on their boats a few years back - St.St. small size - drains into a sink -

sorry can't remember where they bought them - they both said they shopped around a bit -
