Hi everyone.

I need to install an additional outlet on a heating oil tank it's single walled steel and there's no way to access the inside of the tank. Does there exist any kind of tank fitting that can be used, or do I need another tank?

It hasn't been commissioned yet - it was a custom shape and the customer didn't specify he wanted a dedicated drain outlet. The only outlet on the tank right now is the feed to the boilers - which is 5cm off the bottom of the tank. This will leave about 300 litres of unusable (and un-drainable) fuel - which isn't ideal.
 
I would look at a valve with a tapered thread and install it in the bottom of the tank. Have a look in the BES catalogue or their online one which is a bit clunky. centralheatking
