They are inefficient, especialy Zanusi's. Even new fridges of the same

will be much worse.

The efficiency is an interesting argument.

If the fridge is inefficient, then it will be losing power through heat.
That heat then helps the overall house temperature to some small degree
(ok, for heating electricity is a poor / expensive choice). So,
arguably, the more energy to lose due to an inefficient appliance, the
less demand there is on the heating.

Maybe a small, contrived point - but valid to some degree non-the less.

A second consideration would be the question as to how much energy goes
into the manufacture of the replacement fridge, together with
transportation, salesroom energy useage and so on.

A third consideration would be environmental - you have an old fridge to
tip into the nearest landfill, safe disposal of the refridgerant, and
the damage to the environment in the manufacture and transportation of
the new fridge.

Personally, I'd go for the new fridge, but if the OP wants to fix the
old one then every credit to him.
