Ferroli Modena 32C HE combi should do the job, i used to work for a guy who had a bathroom and plumbing shop and i went on the tour at the Ferroli factory to be talked through the ins and outs of it with him.
Can be installed fairly quickly also a 1 man lift and small in size. No heat exchange so you will never lose hot water patented design. Also 5 year warranty and if it fails after that theres only 4 working parts, each costing £50, unlikely but if they all fail will only cost £200 to fix.
Ferroli had a really bad name a few years back and took all complaints and problems onboard to create this one, after being there and seeing it all first hand and seeing them fitted, setup and working in houses i would have one myself.
