Stove installation in bathroom

[Lenny Hardt]

Hello all,

Just a quick one, we are installing a stove in our main bathroom. A inset type. Originally we wanted a cassette type but it was much too expensive. We are going to pipe it out horizontally (upstairs bathroom 2 storey home), but my query is, do we have to use a full length flue or can we use a similar flue system like what is used on oil central heating where it just comes out the wall and is sort of caged in? (Can't upload images to show you what I mean, but I think you will know what I'm talking about.) Does it need to be a certain length vertically, and is it not suitable to add a small flue say 3 feet long once it comes out of the wall? I'm of course going to get professionals in to do this, I'd just like to know my options before going ahead.
Thank you.

I would be checking if the appliance you are after is allowed in a bathroom

Do you mean a woodburning stove? If so the maximum permitted horizontal run is 150mm, and you need at least 4.5m of vertical flue. You're allowed to go out at 45°, but the 45° component can only be 20% of the total flue length, so if you have a 45° section of 2m, your total flue length would need to increase to 10m.
