Boiler options

[Bantam Buc]

So, I'm hoping for some help.

I've searched the forum and found some really useful information but it's also been a little conflicting so thought I'd post up my query for your thoughts.

I'm starting out on a renovation of a bungalow. It's 2 bedroom (1950's build) but we are currently going through planning to effectively double the size with a rear extension. The whole place will be getting updated, new wiring throughout, insulation added throughout (as there appears to be none) etc...

I'm looking at adding wet UFH, a couple of towel rails and radiators and there will be a main bathroom and also ensuite with a shower. I'm a little unclear what boiler solution I should be looking for:
- Combi boiler - Will this be able to support UFH, Shower and rads in the depths of winter?
- Boiler and water tank - Will this be overkill (we don't have children)

Is there anything else I should consider? Urgh, so much to think about.

A combi can run underfloor wet heating. I understand why you want towel radiators with that but why would you want other radiators and not just do UFH throughout?

We are having a mezzanine level in the extension which won’t have UFH hence the need for a rad. Should only be one though.
