Further to my enquiry a couple of weeks ago, I have decided to have
(1700mm x 600mm x93mm) size vertical radiators mounted behind the doors of
3 bedrooms, 1 living room and 1 kitchen. The bathroom and downstairs
toilet can have similar size heated towel rails. This optimum and
arrangement should keep disruption down to a minimum in an occupied
tenancy.
