You can have your brand new boiler installed safely in most rooms, including the loft.  There are, however a few things to consider. Below are three things we think you should definitely think about before making any decisions:

• Your boiler should be installed inside a building and can be fitted to any suitable wall strong enough to take its weight when full of water.
• The boiler’s flue must be able to pass to the outside, either through an outside wall or through the roof.  The boiler installation manual gives the minimum legal distances the flue terminal must be from windows, air bricks, other buildings etc.
• As well as the flue, you must consider where to fit the condensate pipe that takes away the liquid that condenses as the gases cool inside the boiler. We recommended that this pipe discharges internally into the household drainage system. If the condensate pipe is fitted outside, it could freeze during cold weather and make the boiler shut down.
