Tim Bradley (Letters, 1 October) and Adam Halawi (Letters, 7 October) are comparing apples and pears. Most heat pumps in the UK are used to heat water for radiators or underfloor heating. Tim’s heat pump is heating air that is being ducted throughout his Swedish property. Assuming his ducting was already in place, all that would have needed changing was the heat source. But Adam’s radiators will need replacing with larger units due to the lower operating temperature, and I suspect his insulation will need upgrading.

• Zoe Williams thinks that Labour politicians should wear a uniform to stop fashion sleaze (7 October). She is being ironic, I hope, as the 20th-century history of political uniforms didn’t go well.

• The Housemartins, Everything But the Girl, Mick Ronson, the Bootleg Beatles, Blur and Oasis were all mentioned in your sports pages in Tuesday’s print edition. Is this proof that sport is the new rock’n’roll?
