Used a propane catalytic heater in the boat in Alameda, CA during the winter without any problems. Turned it off before I went to bed
and did not burn it all day long. Mainly used it in the evening when I was sitting around reading or playing on the computer and in the morning to warm the boat up a bit before I got out of bed
. Also it burned a bit of fuel
. It was designed to use the short disposable propane bottles and would burn through one of those in about 8 hours of constant use.
Was never that happy with the possibility of CO poisoning so bought a Dickenson Newport Diesel
heater. Never got it fully installed before leaving CA so can't report on its heating
ability or ease of use. Was not and am not concerned about CO with that outside vented heater. Hopefully when and if I make the sail to Alaska
it will work without the drama of back drafting. In any case, have installed a CO detector just to be safe.
