“The warranty gives me peace of mind,” explained Mr Sutton who fought throughout the War in Syria, North Africa, Sicily, Italy and France and has numerous medals for bravery. “I plan to see it through, and I hope I can extend it after 10 years if necessary!”

Mr Sutton was wounded in the leg at the Battle of El Alamein in Egypt and again in the arm in Italy, before taking part in the D-Day landings and subsequent battles in France. He lives an independent life at his home (number 101 on his street), which he keeps at a constant temperature of 23 degrees, day and night.

Mr Sutton said: “Like my last boiler, my new one keeps me lovely and warm. It's like being in the desert – except that was a very dry heat.”

The new boiler replaces Mr Sutton's last Viessmann boiler, which was installed in 2006. Both were fitted by The Boiler Club Ltd in Ravenshead, of which he has been a customer since 1987.

The Boiler Club owner, Andrew Dumelow, said: “Mr Sutton asked us to choose his new boiler for him because he knows we will always do the best for him. Considering how hard his last boiler worked, it did very well to keep going for so many years, so we wanted to replace it with another Viessmann. Mr Sutton's war-time record is amazing, but, being the person he is, he always plays it down, saying, “We did what was expected. He is full of life with a great sense of humour. A really lovely customer to have.”
