What boiler?

[The Goose]

Got a possible replacement coming up and was after some suggestions for what to look at and what you guys like to fit and why.

iro 30kw, open vented, small enough to fit into kitchen cupboard if poss but probably not a deal breaker.
Any suggestions much appreciated.

For combis recently I have been either worcester, vaillant or ideal logic and system boilers usually worcester or vaillant. But not done an open vent one for a while now.
I was never a huge fan of the open vented small worcesters or vaillants but I see the vaillant has a newer design heat exchanger which is a different lay out and is aluminium. Are they any good?

Generally only fit vaillants, but their open vent boiler is rubbish!
Can't you make it a sealed system? Or fit a plate heat exchanger to Keep the boiler sealed.

Thanks guys.

The logic plus looks similar inside to the combis. Are they a good bet?
I like them as a combi etc and have not seen any major issues with them.

The reason for not wanting to change to a sealed system is all the rads and valves are old cast iron school type rads and dont want to create a leak. Also steel pipework so not easy to alter if a rad did need changing.

Do you mean a heat exchanger in the current boiler?
How much space for the boiler? Its a top kitchen cupboard size but could be altered to suit if that was the best solution.

Have a look at plate heat exchangers that would be the best option then keep the rads ov and the new boiler pressurised
