Post Subject: Anti frost protection

I am looking to provide my 57' boat with some anti frost protection whilst away from the boat this winter. my intention is to use either 2 x 2ft tube heaaters with thermostatic plug or 2 x thermostatic oil heaters to keep the chill off. The question is which is the most preferable. I intend to fit a galvanic isolator prior to plugging in the shore power for an extended period. This is the first full winter we have had the boat and I want to avoid the problems we encountered when the boat was handed over to us last January when the boat required a new heating circulating pump and fresh water pump before we could sail the boat away. Central heating system has a good level of anti freeze and fresh water system is isolated from the tank and taps left open. Any advice on the best heaters appreciated. Rob Eddon

I think the more popular form is low wattage greenhouse type tubular heaters. These are designed for use in damp conditions where insects can crawl into small gaps. I think that you may find they are available with built in thermostats. Two further points. I trust you are not intending to run these off an inverter - you do not specifically mention a shoreline. Remember that it is not unknown for marina supplies to trip out leaving your boat with no electricity so using heaters does not avoid regular visits. Tony Brooks

Further to my reply above. I have just read a report that an unnamed insurance company has recently amended their clauses to say that any heaters used must be designed for marine use. I know of no such heaters. Please carefully check your insurance documents Tony Brooks
