"Can this be right?"

Well it can be.

If it's a standard (sort of) sized semi it seems rather high though for a front room.

What size is the room and how many outside walls?

Cheers

it all depends on the size of the room. You have to find the cubic size of the room ie height x lengthxwidth and how many outside walls you have. also i think you need the size of anywindows.what you say above does sound alot. Hope this help

When you have worked out the size of the radiators, think about where to put them, and how to control them and what the next person who lives in your home may require.
A radiator that can just cope with a rooms heat loss may result in a room that feels cold for someone else.
A radiator that is fitted on an outside wall, will loose a lot of heat to the outside or to the wall cavity.
A radiator fitted under a window will loose a lot of heat, merely warming the window glass.
A radiator where the hot feed enters at the top will give out 15% more heat.
