Anyone know of a good, reliable dehumidifier?

But what's the downside? If there's no mould or mildew, what's the damage? Do you have a dehumidifier working in your car in the drive in the winter?
It’s mostly the smell. Fans of ventilation universally don’t notice the ”boaty” pong when they reopen their boat and are in denial (I’ve seen it often) when people with them point it out. ”What do you mean, smell? It smells fine in fact it doesn’t smell at all”. Put it this way I wouldn’t trust them in a wine tasting to tell the difference between a fine wine and a dead rat.

If your boat would smell without a dehumidifier then by all means dehumidify. Or fix the leaks. Up to you.

My boat doesn't smell. The engine's clean. The heads are immaculate. The bilges only contain dust.
 
My dehumidifier is Japanese and seems better made than all the chinese/korean ones. Its a Toyotomi made in Nagoya and is a dessicant type so is supposed to work in lower temperatures. The model I have is a TD-Z80 . We must have had it five years or so now and it has proved very useful.

I would certainly recommend the make.

Yeah, I do. Old Skoda doors leak so I dry it out occasionally!:)

We have used this one for the last 6 years without fault:-
Eco Air DD122FW SIMPLE 7 litre Desiccant Dehumidifier
Has a simple high/low power setting and adjustable humidistat. Works fine with a timer cutting power to it as this is exactly what the humidistat does as there is no cool down period. Can be used with continuous drain as well.
Have the similar DD1 Simple - restarts fine after power switched off and on. Keeps 34' boat at 50% over winter. Used for three winters now.
 
Not proved at all. You're welcome to come and do a "sniff test" on my boat, just to convince yourself that you can be wrong.
Proved that you would deny or not notice the smell, but of course I can’t prove that your boat is really the incredible exception that gets through a UK Spring, Autumn and Winter by ventilation alone without a smell, so you can leave your cushions and towels and clothes on board without an issue. If it is, then well done but until the internet has found a way of smellyvision then I will keep believing my experience and you will doubtless trust your nose. On another note, do you often have women sailing with you as crew?

So you don't want to learn something by coming and doing a "sniff test" then? If you're happier just to believe your own prejudices, fine.

Yes, my wife comes along on the boat, although less frequently than she used to as she now has some mobility issues after smashing her femur in a silly horse-related incident. She is blessed with a wonderful sense of smell; one of the reasons why I keep the boat squeaky clean.

As a matter of interest, how many boats have you actually been on when they were opened up after the winter and why?

Endless examples of my own, but I’ve also done a lot of crewing on other peoples over the years and it doesn’t have to be opened after a whole winter - just a fortnight outside high Summer in the UK seems to do it for that horrible and unnecessary pong - and that’s the boats with dry as a bone bilges.

I am of the school of thought that uses dehumidifiers, and have done since living in Hong Kong in the 1980s and 1990s. There you had high temperatures and 99% humidity for a substantial part of the year, and if you did not want bad mould you used one or more dehumidifiers unless your whole flat was air-conditioned.

As a broker I go on quite a lot of boats and have occasionally met owners who think ventilation is all that is needed that have damp boats. Some do however get away with it. I suspect the difference is the amount of salt that ends up below on crew hands, oilies etc. and how thoroughly and regularly the boat is cleaned.

On the boat, in a garden building, and at home to dry clothes in a spare room I use Meaco DD8L dessicants, they work very well, but several have gone wrong over the years. From one supplier they come with a 3 year warranty, and out of warranty Meaco will repair for a fixed price £70. I would not put a compressor one on the boat unless a heater was also run or it had an auto defrost function: I have seen a compressor dehumidifier ice up so badly it stalled the fan and killed the fan motor.

In our cellar and in two very old stone properties I use compressor Ebacs, on the whole very reliable and long lasting. I did try a couple of £100-ish Screwfix compressor ones which were very good until one failed to cut out when full and soaked a carpet that was not found for some time. The other did the same a few months later. Both just out of warranty by then. I am afraid they went in a skip.
 
Ventilation is fine if that's all you have. Its better than not ventilating. But think of it logically. If you ventilate well, your boat will be at the same temperature and the same humidity as outside. Now think of all those really damp mornings you typically get in autumn through to spring when the air is heavy with moisture. Your boat will be cold and damp inside. On the same day my boat will not only be bone dry, but warm too.
Under "normal" circumstances use the boat throughout the year, we have to pay for the marina so might as well make use of it! This means the water tanks are full, water pump is full and primed, all the beding and food is still on board. This is only practical with a dehumidifier and heater on board. As CBL says if you cannot get power the ventilation is the next best thing but why let damp/cold winter air in you living accommodation. When there is snow on the ground and blowing around i am glad that we have frost protection, a dry boat with the hatches closed.
 
I hire a lot dehumidifiers and have found Ebac to be some of the best reasonably priced dehumidifiers
+1 to that,have used one at home and another on boat, for 27 years. both ebac, home one failed last year, so bought another for home.
I run the boat one every weekend, as i overnight frequently in the winter. never leave it on in the week.
 
Sorry to jump on here but has anyone got any experience with the Maeco 12l low energy dehumidifier - they are meant to be very cheap to run but I’m concerned that it may not provide enough heat (if that makes any difference?). Would the DD8L be a better unit?

It's a compressor dehumidifier, about the same capacity as my Seago Smart Dry 2, which I talked about earlier in the thread, but lower energy consumption.

I'm sure it'll be fine. I'm inclined to think that the superiority of the DDL8L is overstated, unless you have really specific requirements.
