Less parts to go wrong simple as that boilers do a lot of work and anything with mechanical parts eventually break down so less means less stress surely
Less complicated to repair with only four moving parts, also should be a lot less spare parts to carry around meaning hopefully a near first call out fix.
It was my sons christening on Sunday. Buffet for 40. It cost me a kidney, I had to buy it all in. Caterers brought it to the house in the morning. I ate like a king!
