"A tank for kerosene was a better cure was a more reliable cure fore livaboards.. "
I also found hard starting of my old Espar was related to the temp of the diesel in the main tanks, as I didn't have a separate source of kerosene plumbed in. Seemed ironic that if you didn't need heat, starting was easy, but when you really needed it, returning to the very cold boat for a winter cruise, the silly thing wouldn't start. Once the fuel was warmed up after a good run on the main engines, the heater would start just fine. In the first few years I had the boat, with that system, I spent more $ trying to get the Espar happy than total maintenance on 3 diesel engines.
Probably affects the Wallas the same way.
