    tip from a gas engineer on frozen condensate pipes

    tip from a gas engineer on frozen condensate pipes 2nd Mar 18 at 11:56 PM
    I know it's a bit late now but just thought I would share some tips.
    All of the condensate pipes I seen frozen where terminated over a grid or gutter. The external air gap causes the freezing and increasing pipe size or insulating the pipe won't do much to prevent this. Trace heating might but it's not something I've tried.
    We always try to terminate directly into a waste pipe if possible.
    If you can't do this then at least terminate below grid/grate level or fit a drain guard.
    Boiler installed downstairs is always preferable. Keeps the condensate pipe run short and easily accessible.
    I'm fitting a new boiler at mine shortly. Condensate will be straight out the back at fairly low level then teed into external soil pipe 6 inches away. Best way in my opinion. Soil stacks are warmer inside.
