A church official has spoken of the problems encountered heating a cathedral. Canon Tim Pullen said Coventry Cathedral, which was constructed in the 1950s, was "notoriously difficult to heat" due to lack of insulation and its huge floor space. He also commented: "Obviously energy bills are going up and like everyone else we're subject to the vagaries of the market so we're hoping this is going to give us a more consistent and lower cost basis to heating."
