Can I boiler be installed on an inside wall?

[indus]

Is it possible to install a boiler on an inside wall and then run the flue through a false/dropped ceiling?
Is there a maximum length that the flue pipe work can run before it vents to the outside?

Thanks

I’m just guessing but I would imagine it depends on the boiler but I think you can’t box it in permanently as it must be fully accessible for inspection purposes so might need inspection doors etc. I’m sure I’ll be corrected very soon!

A boiler can be installed pretty much anywhere, you are really only limited by the manufacturers flue options.
Some manufacturers only offer Coaxial flues (a pipe within a pipe) and tend to be more limited by length.
Keston boilers (Ideal boilers really) have very long Twin flue pipe options.
Access panels must be fitted to allow inspection of the flue and joints...check the requirements before work commences.

Here's an example. See page 18 showing a horizontal limit of 6m to 7.9m for this boiler rage:

Obviously the flue will need to run parallel to joists due to size.

Navien permit up to 100 meters of flue with their twin system. Yes, 100 metres!

Remember the flue needs to fall back towards the boiler so make sure you have enough clearance for the length of flue
