New Boiler but which type would go with a shower pump that is only 1 yr old so do not want to get rid off!?

I currently have an conventional heating system with a Baxi Bemuda back boiler, hot water cylinder, cold water tank in the loft. I've had good things about having a combi BUT this does not work with a powerful shower pump, is this correct?? I've only had my bathroom done a year ago & had a shower pump... show more I currently have an conventional heating system with a Baxi Bemuda back boiler, hot water cylinder, cold water tank in the loft.
I've had good things about having a combi BUT this does not work with a powerful shower pump, is this correct?? I've only had my bathroom done a year ago & had a shower pump fitted and do not want to get rid off.
So which type of boiler/central heating would suit an 1930's house to bring it to modern day standards.
Any advice would be appricated with approx costs involved.
Thanks.
