Which boiler to get

[mc_rm80]

Currently have a combi Vaillant Boiler which has lasted 30 years! (still working just not efficient).

Don't know much about boilers but as im going to spend alot to relocate it to the garage have done some research and it looks as though a System boiler with Megaflo seems to be a good option.

I have 2 bathrooms and 4bedroom house good water pressure so this seems reasonable or is it abit overkill and should just a Vaillant Eco Combi?

Decision on what type to get is dependant upon loads of different variables that only you can answe but for most reliable and ones which you will still be able to fix and get parts for in 25 years vaillant again every time!.
