Hi
Trying to decide on a new boiler system!

The question - Assuming all the boilers are of a similar efficiency, is there an efficiency advantage of a using either a combi boiler, or an open vented boiler or a system boiler?

Although an existing system Im not bothered about the work load! or to some extent the additional fitting requires

Your real choice is between combi, combi with some storage, and pure
storage. Which hot water system would suit you best depends on many
factors.

For this question we have a FAQ - see boiler choice below.

An directly comparable instantaneously combi will be more thermodynamically
efficient in the provision of hot water than a storage system. Whether it
will meet the household needs is another matter.

A sealed system might be more efficient than an open vented one, as open
vented ones frequently go wrong in a way that reduces energy efficiency.

Really? Think if you did a straw poll on here of previous posts you'd find
far more about faulty pressurised systems.

A one pipe combined feed and vent is virtually trouble free. Install a
Magnaclean on and an air ejector and they work well indeed.
