Ice , but hopefully no damage

[Momac]

The marina water was frozen over this afternoon so that must have been building all week. But the boats are not locked in place by ice.
There was however some ice (and some water) in the tank of my dehumidifier on the boat.

At home a sandcastle bucket left out had filled with rainwater had become fully frozen

I hope you folks dont find any ice damage on boats or elsewhere when the thaw comes.

I have two oil filled rads on tstats. Not taking any chances!

You may need to rethink your heating arrangement, seeing ice in the dehumidifier tank is not good, I would be thinking what else eg. the fresh water pipes etc.

The other thing people often forget is the deck shower (if it's a shower head on the bathing platform)...

I guess it's a bit late suggesting to drain the hose now.

Worth checking when turning the pump back on that it's not leaking into the transom bilge.

Yes it does seem more frost protection heat will be required if another similar frosty snap is forecast . I have not seen ice inside the boat develop on this boat previously . Owned the boat since 2014. But winters have been relatively mild with frosts short lived since then.
Thankfully the dehumidifier doesn't seem to have been damaged.
I had drained the domestic water a few weeks ago but always concerned some water probably remains.
The thaw over the next week may not necessarily reveal any issues . I am not expecting to be refilling with domestic water until March.

Is there a drain/bypass hose to fit to the back of the unit, bypassing the storage tank?
Our desiccant (cool weather) dehumidifier runs for more than six months of the year and can fill the storage tank overnight, and shutting it down, in the right conditions, so hose bypassed into a sink.

I prefer not to use the hose
Not sure what the outcome might be if the water in the drain hose should freeze.
I live within a mile of the boat so can get to it to empty the tank as required.
On a low setting (which is ample) it takes the best part of a week for the dehumidifier to fill its tank with last week being an exception due to the dehumidifier being inactive when its very cold.

Exactly what we do, drain the dehumidifier into the sink. Hopefully the sink drain doesn't freeze ? ?

I leave the taps on throughout the boat and remove the shower head, in my case the tube heater is pretty much underneath that area.

Indeed. It's the removing of the shower head (especially if it's one of those that you press a button on the side of the head for water) that saves it.

blow down the pipe to clear the mixer valve.

I'm a little worried as my engine bay tube heaters didnt turn on due to a faulty thermostat. Hopefully no damage.
I also drained the domestic water tank and left all taps fully open but the galley tap still froze. A hair dryer soon sorted it.
