Hi Thanks to you all for your help. I think I'll go with the engine to one coil and the boiler and eberspacher to the other. I like the idea of using the eberspacher as a engine preheater thanks again

Hi Does anyone know if it is possible to run the boats engine cooling system a solid fuel stove with back boiler and a eberspacher hydronic D5W water heater to a twin coil calorifier. I have a twin calorifier already fitted with the engine and boiler but what I would like to do is fit an eberspacher and have 2 connected to 1 coil a 1 to the other coil. Thanks

Hi all Does anyone know of a 12v float switch that can power on a Jabsco 12v Par Max 2.9 water pump? I want to use it as a shower sump pump switch Cheers

thank you all for your replies and help my wife phoned them on Tuesday armed with the information you all provided and spoke to the person she talked to last time. this person apologised for not phoning us last week and someone had been over to look at the boat, it was as they suspected that our boat was at fault and its electrolysis. my wife told them that they have the electrolysis all arse about face and the rust is most probably caused because of bad preparation or bad application of the blacking. she asked them is there someone who knows what they are talking about there and could she speak to them. after a couple of minutes the marina owner came on the phone and my wife explained the situation and what she had been told, she then enlightened him with her newly acquired knowledge. he apologised for what had happened and what she had been told and she was correct and the person she had spoke to had got it all wrong. he then waffled on about how many boats they have painted and we are the first one this has happened to. he then told my wife that he will contact the paint manufactures and personally go and look that the boat and get back to us ASAP. he phoned back yesterday, he has been to look at the boat and he then phoned the paint manufactories whilst there they told him it is not the paint but the boat electrics. he then tested the outside boats hull with and without the mains line connected. he got a slight reading at the stern and nothing anywhere else and no change with the mains plugged in. he told my wife that possible the problem is the boat is not earthed or there is a problem with the earth. also the bow anodes are worn a lot that to look at the ones on the bow he would not think that they were new in april. he thinks the boat is acting like a big anode and being stripped of the paint and metal i thought the earth was at the back of boats in the engine room is that why he got a slight reading with whatever tester thing he used, did he get a reading from the batteries 12v electric field. since april the mains has been plugged in for about24 hours in total so i don’t understand why he keeps going on about electrolysis. i am sure our boat is fitted with a galvanic isolator to cut down on corrosion wear on the hull and fittings. how can i check to see if isolator is working there is a good earth to the boat. what can i do to make them see that the most probable cause to the rust is that it was not painted proper in the first place, should i get a surveyor to have a look at our boat

Hi I had my boat blacked in mid april this year and it looked ok for the first month or so but around the end of may I noticed rust spots along the water line at the bow. I had a good look and found rust spots along the water on both sides and the stern also a couple of patches about a metre by 200mm between the gunwale and waterline. For the next 2 months and masses of phone calls to the marina that did the blacking they agree to send someone to have a look at it, unfortunately I was on holiday. After belling them for the past few days my wife finally got hold of the person she needed to speak to. They told her they have blacked 100’s of boats and this has never happened before they also agreed that there is a problem but it was most likely our fault because we don’t keep the mains connected when we are not on the boat. He waffled on about electrolysis and the anodes and we should keep the mains connected all the time to stop the rust building up on the boat and he will arrange for a surveyor to have a look. Surely if the blacking is done right it should last 2 to 3 years and not 2 months or is what he said about the mains hook up keeping rust at bay correct. I would be grateful for my advise on what can we do to get this sorted thanks

Hi For some unknown reason the horn on my boat is at the stern and I would like to more it to the bow. Could I use 1.5 brown stranded conduit wire from the +12v push switch to the horn and connect the blue ground to the bow light. My boat is 72 foot would there be a problem with voltage drop. I would also like to fit two 12v brass eyeball switched downlight in my cabin could i use this 1.5 wire for this too thanks
