I have a feeling that I'll be using one myself in the next build

They'll be indepently switched and driven by an stc1000 and timer etc - my plan is, fill the tank set the timer, switch both heaters to on and set the stc temp.
I get up and walk to the brewshed, HLT is up to temp and I switch off one of the heaters so just one comes on now and again to keep the temperature stable. 1.5kw switching on intermittently rather than 3 - just in, case. It only needs a kettle on in the house, coffee machine and dishwasher/washing machine to possibly trip something. I'm not an electrician so i don't know the full details, just playing wary. It also looks nice and if one packs up, there's the second one to fall back on.
re the Float Switch - goodluckbuy.com via eBay - I got two, no plans for the second one yet but good to have a backup or it may come in as a level sensor for filling the hlt somehow.
