Just found one of these on fleebay:-

It is a relay with a fuse in line with the Normally open contacts.
I only plan on one extra bit of kit, a DVD player, so this will suffice.
Then I spotted this at the same shop:-

This is a remote with a relay. At the price worth buying for a play. Might be able to fire the Aux heater remotely from indoors
