The victim's Simon Gouldstone told reporters his father had worked on the phone during the Second World War before going to the post office.
The former civil servant, 67, said he found his father in a "semi-conscious state" in his bedroom after the back door was broken in.
Simon, who was alerted by a neighbor, told reporters: "I do not know how they can live with themselves.
"As a member of the family I'm shocked, a member of the human race I'm lost for words at man's inhumanity to man I'm afraid."
The violent raid took place in a 20-hour window between 2pm on November 5 and when it was discovered, but officers believe it was most likely under cover of darkness.
A black Panasonic 26in TV was stolen from the house along with a number of other items, police said.
Mr Gouldstone has lived in the country for more than 60 years, and he has never seen it before.
The couple also had a daughter.
