Ariston unvented water heater indirect

[mcniven]

Customer called, has the above unvented cylinder, she sent a pic, the expansion vessel is mounted to the top of the vessell fixed...

is this just a 3/4 bsp thread into it ????? Other than ordering the right vessel, would anything else be required to replace???

Never seen this .. :/

Yep. 3/4 inch. Nothing else required except your unvented ticket.
