my heater developed a major leak (a flood) today from the matrix.
It is a SII gold round type - does anyone know if it is easy to fit a later one or have a spare early heater that doesn't leak, or failing that any heater that will fit?

if all else fails, can you bypass it? or do you need it for the additional cooling :s

I think the matrix out of the SeriesIII will fit... if you can find one.
