The original diesel heater was replaced by a previous owner some time ago. The present chinese diesel heater performed well from the time we purchased our NT 32-238 in 2020 until last fall when the thermostat became erratic and finally failed to light off near the end of our 2024 cruising season. Has anyone recently (in the last year or two) purchased a chinese diesel heater and can recommend one brand over the other? No need to mention repairing our old one as we want a totally new one. Many thanks, Harry Hungate and Jane Lothrop Bessie
