Morning chaps,

this weeks project is to replace the immersion heater element in my mates thermal store with a 24v one that will act as a dump for the solar/hydro that I fitted for him. I'm thinking that it's just a case of draining it down into a suitable container ( I have a 700lt bowser ) refilling it with an electric pump then bleeding if ness. Any tips, help, advice gratefully accepted. Well apart from call in a plumber as it's here http://www.uniquescotland.com/raasayschool/index.html so not even an option.

Cheers, Paul

 From experance drain as LITTLE water out of the tank before cracking the heater boss, as to keep as much strengh/structural stability in the tank. you would be surprized how easy it is to twist and collasp an empty copper water tank!!

good luck Peter

Thanks Peter,

I have to say that I'm a little concerned about this issue as the old unit looks like it's been weeping slightly for years, hopefully this is NOT because of some loss of integrity in the metal around the thread insert  Shocked

I'm working in Broadford over the next week or two. If the ferry man can get me onto the ferry I'd be willing to help... I'm getting into Uig at about half five tomorrow afternoon. Have any number of tips for removing immersion heaters.
Box spanner and long pole is the first start, if it isn't going to come off straight away, then drill a row of holes across the boss until it virtually collapses on itself... Dont be tempted to use a hammer.

Hi Sleepy,

Me finished last night so I've spent the day fitting a new back boiler in my own stove, though I did manage a trip over to Torran to look at the dump load job for tomorrow. It's not going to be quite as straight forward as I'd anticipated, the new 24v element has a much larger boss which means I'm going to have to remove quite a bit of foam and re position a stop tap :-( Hopefully I'll get it finished cos we're off to http://www.tartanheartfestival.co.uk/ on Friday and I'm putting 5 pigs away on Monday  Cry

We really must meet up, Paul

seems like most of the staff here are off to Belladrum this weekend.... I'll catch you one day. I was only going to offer you an immersion heater box spanner and say hello... If I take a day off in the next week I might pop over as I am curious to see this famous road with my own feet.

Hi Sleepy,

you should get your ar5e over to Bella, I might even be able to help out on the ticket front, as the 'Peatbog Faeries' and 'Grousebeater Soundsystem' have to be seen to be believed :-)

PS we should be on the Co Op  car park in Broadford at around 9:45 am on Friday stocking up with 'Morgans spiced rum', Magners cider and red wine in preparation for the fest :-)

Cheers, paul
