  1. Any chance of a picture of your install?
  2. Thanks everyone. I have ordered 50mm cable, terminals and the proper crimp tool to fit them.
  3. Yes 12V lol. They are supposedly 150ah deep cycle batteries, they arrived this afternoon but I am a little disappointed that they only had 12.55v in all of them. I have put them on charge for a day or three. My boat only has an 80amp alternator which has to charge the house batteries and engine battery so 25mm link cables will probably be fine but I will look for bigger ready made ones before ordering. I hope they perform better and live longer than cheap 110ah ones...
  4. Thats good to know. The current setup 2 x 110ah batteries and 200w of solar doesn't appear to be enough. We only have 12v fridge and 12v tv and by the morning they would be down to 12.4, if the solars control meter is anything to go by on a sunny day the batteries would be fully charge by the early afternoon. The current batteries have lasted 30mths and last weekend they were 11.2 by the morning. Thanks. I am not sure what size the current link cables are. Once I have made the battery box and have then sitting in situe I can work out what lengths I will need and order a full set
  5. Thanks, I must be going nuts as I have read it over and over and cannot see no mention of it not working on 3 batteries lol. Thanks, it looks like I will have to go the method 2 route. What thickness/amperage link cables do you think I should use? The most common sizes available ready made seem to be 100amp 16mm2 and 170amp 25mm2.
  6. Hi All, I have just ordered 3 150ah deep cycle batteries to replace my 2 old 110ah ones. Can someone tell me the best way to wire up a bank of 3 in parallel so they all charge up balanced? I have read through this page http://www.smartgauge.co.uk/batt_con.html and method 3 would be ideal but not very practical with requiring extra external terminal posts. Method 4 looks simple on 4 batteries but I can't get my head around using it on 3 batteries lol.
  7. Ok, having just spent 2 weeks on the cut I have discovered that the amount of water being circulated by the engine at normal cruising speed may not be enough to heat the calorifier. The pipe from the engine is hot but the return pipe stays pretty cool until you get the engines revs a bit higher. I was moored up one day and revved the engine about 2500rpm in neutral and it heated the tank up a fair amount in an hour. It it possible to fit a 12v circulating pump in the system to improve flow?
  8. I don't live aboard and its only ever had leisure use since new in 99.
  9. I had one in my first house that was about half full of limescale, it looked like cornflakes and like you say it still heated ok. Unfortunately the boat's cylinder does not have an immersion heater that I could of remove it have a look. If there is a large build up on the coil i would expect that would affect heating time. Its looking like I will have to bite the bullet and get a new one. If I get a Surecal unit at least I will have two more options to make it heat up quicker if required (ie diesel heater or Immersion).
  10. If I bought a twin coil could I pipe up both the coils to the engine or would that cause more risk of an air lock or would the engine not be able to supply enough hot water fast enough etc?
  11. I have just found out the water is classed as very hard in the BOA area, I thought my friend may have been wrong
  12. I was wondering the same, it has had a total of 2200hrs use. The boat has pretty much always been filled in Bradford on Avon but I don't know if its a hard water area. A friend said it is probably soft as all the buildings are made of sandstone, I will have to find out.
  13. Both hoses rise up from the engine through the bulkhead and down to the connections on the tank. There are no bleed valves anywhere, I disconnected the return pipe/hose at the engine end at the weekend started it up and there was a decent flow of hot water coming from the hose, I also topped the coolant level back up with antifreeze afterwards but it still took forever to get hot water. I was thinking it may just be that tanks built 12+yrs ago may not be as efficient at heat transfer as modern ones, I assume its just a coiled pipe with no exchanger fins like a surecal type???
  14. Thanks, the 55 is the largest vertical I can fit in the wardrobe where the old one is currently fitted.
