Apologies if this has been done to death elsewhere - Looking for some advice on changing our boiler.
Current set up is an Ideal Mexico FF460 Floor Standing boiler which was originally on a HW gravity feed. I installed a pump and converted it to Y-Plan about 4 year ago. HW tank was found to be leaking and this was changed at the same time.
Now looking at refitting the kitchen and would like to change the boiler to wall mounting but still want to keep the hot water tank so ruled out combi.
Heat load using whole house method is about 18Kw (4 Bed Detached in Lancashire)
Looking at Veissmann, Vaillant and Worcester Bosch (in that order) but can't decide between a system boiler or heat only.
Apart from having less components in the system (ie. Expansion Tank, Pump, 3 Way Valve, Programmer) all of which are relatively new, are there any other benefits to commend a sealed system over an open vented system.
Would just like a bit of advice in advance before getting some quotes.
Cheers
