ok
Yes I think its a good diy option and a panel that will do what you need.
Its stable kit but you think a 'spike' has killed your current one
But be careful on current load (2 bells in sab mode) and you should be fine
bit of advice, don't get funny with those you want free help from
but there are bodies that inspect installers I would go down that route first
If your going down the diy route give Texecom tech a call they will help you with product choice without using tsi
I can see your point but it was a bottom end system then.
But as its been totally fault free for years then its worth sticking with.... oh wait
If it was anything else, fridge, telly etc what would you do?
