I'm currently renovating a double barn in France. I'm considering using an air source heat pump (though not decided which one) & radiators to heat two 7m x 7m rooms downstairs & the equivalent area upstairs. One of the upstairs areas will be a mezzanine. As I would like to use the heating during winter, and leave to 'tick over' when we aren't in residence, can a form of antifreeze be added to the radiators & pipework? Temperatures are often at -20C in winter. Also which radiators may be the most appropriate?
A bit of a long winded message - sorry.
Many thanks in anticipation of your reply. Rob
