Oh Noah! He's arrived.

The ark is narrow (the play boat is also narrow but more tug-like) and I've never counted the spiders aboard but there are two barkers, a munchkin, (and assorted smaller fluffies). I like CWDF but was recently alerted to this fine establishment by the back and forth between threads on here/there and thought I'd drop by to see if anyone on this side had actually used their shore power for heating as opposed to revelling in making life difficult and sooty. (Not the puppet, I don't know what it is but I understand there is a 'thing' about puppets...)

Partially.  We took one of these

    to our boat years ago. A lot of people have these little 800-Watt fan heaters fitted inside their cars (in Finland) to warm them up.  It helps the windows to be ice-free, and is all round more comfortable to get into a car with the inside air already around 20 degrees Centigrade. It is in connection with a block heater which warms the engine coolant, so engines are easier to start and demand less fuel, and it reduces engine wear-&-tear all round. Also less fuel for heating the engine means a cleaner environment.

When it's cold and we have mains power (from the shore) I sometimes stick ours into the engine 'ole for a few hours, deckboards closed, so the engine room & engine get warmed up a bit. Or we can have it buzzing in our kitchen (the coldest inside part of the boat) early in the mornings to take the chill off.

Welcome indeed. We are on permanent shore power when the boat is in the marina, but when we are not on the boat we don't heat it, we just leave a dehumidifier running over the winter months. I think an oil filled radiator or two might be a safer option than a fan heater - the latter can be easily blocked by cushions / clothes / stray cats blocking the outlet, although as you said, mounting it on the wall virtually eliminates that issue. Just go for it, but be sure that if you have a Combi, it won't take over running the heater from the batteries should the shore power fail / trip. It would need to be set to "charger only".

I am on shore power during the winter but I wouldn't dream of using it for heating ...... no it's not that I am too mean ...... I mean I am mean but that's not the reason I don't use it for heating

with a fridge freezer, washing machine, tumble dryer and a dishwasher, electric toaster, hob, and full size oven..... oh and an electric kettle (but only a 1Kw model)

well I only have a 16A supply so adding electric heating struck me as being a bit OTT

jim Riley - oh, so sort of like a cross between a catfish and a troll? Wow...
naughtyfox - in my old boat engine is resplendent in its own room but in new boat it is in a little cubby hole (modern style trad) so I might even think of one for that now I suppose...
dyertribe - I used to have jewellers as land neighbours and moored next to another floating one the other day - lovely to see more sparkles on the cut
Telemachus - good point abt electric failing... it hasn't to date but wouldn't want much more than the fridge to survive if so I suppose. Mine wd switch to batteries by itself I think so will take a look at that.
JohnV/jim Riley - the one I'd found was only 500W, that was part of the attraction. Will have another look at caravan ones though...

Thanks all!

But I am a silversmith in my land based spare time
