Excellent thanks, these are a third of the price in the chandlers (hey ho, what's new) and there is a choice between redring and Philips. Boat is 10m so a 3fter should do it. No TLC branches near us but Newey & Eyre do them.
Mine were brought from someone who used them on a Fairline Mirage 29ft. 2 in cabon, 2 in engine bay (twin Volvo 145A's). They are 120 watts & 3ft each and he had a thermostat set to around 6C on each pair.
I've also acquired a dehumidifier to put in the cabin, which everyone tells me to run on a timeswitch for a couple of hours a day.
I installed two in my engine room, 1 either side of the engine, 2 x 120 watt. Used to have one in the cabin, but removed it - make sure they have a grid type cover - they get very hot and will burn you badly. I also put a notice in engine room as these are uncovered.
Know where I can get the brackets for these heaters tlc dont appear to sell them seperately and I've broken one of mine
(now how do I get one of those sad little yellow faces at the end of the sentence)
"The Med has got me" (no not the Medway the other Med)
As regards brackets the shortest ones are only about a fiver and I believe all the same dia. buy a couple of little ones and nick the brackets!
You've found the same as me, that their not meant to be trodden on!
