Hi All
I am musing about finally replacing our anciente back boiler (Baxi
Bermuda, part of a Plan C system dating back ... quite a bit)

One possibility I am considering is having a system boiler fitted rather
than a combi. On question - would it be necessary/advisable to replace
the cylinder at the same time, or could this be kept?

Thanks & Regards

If your cylinder is as old as the rest of the system it will be wasting a
lot of energy in the summer (when heat leaking out isnt useful). I
personally prefer boiler/tank combinations. Combis are too €œeggs all in
one basket€� for me. A tank with an immersion heater is very useful back-up
in case of boiler breakdown.

Combis are good where space is a premium.
