When Nick Palmer upgraded a 200 year old coach house near Wetherby in West Yorkshire to a new four bedroom home, he was proud to install an air source heat pump as part of the renovation program.
“I wanted to do the right thing,” he says. “That also made financial sense. At around £ 14,000, the cost of the heat pump and heating system, including solar panels, was more or less the same as installing a gas supply to the property and installing a boiler and central heating.
That was in 2012. Nine years later, the 48-year-old management consultant is frustrated and faces a financial loss of thousands. Typical travel costs since installation to investigate persistent problems ranged from £ 600 to £ 700 per year.
