Vented hot tank pressure problem

[Paul Kelly]

I’m fitting a vented copper hot tank heated from a Stanly Range in a mobile home Due to height restrictions I cannot site a header tank. But can vent to outside. Is it possible to use a pressure reduction valve and connect to the mains gir water supply

I’m not entirely sure what you’re asking or trying to achieve. Which part are you wanting to connect to the main?
