Does it have a pilot light or ignition on demand?
It uses no electric
power. It uses a manual pezio electric
interlock pilot light. You slide to start position, hold pilot open and press ignition., hold pilot lit for a few more seconds and release, The slide to operational position and pilot remains lit as long as you want. The burner lights on demand. You can dial the flow rate of the hot water
to deliver higher volumes at a low temperature or lower volumes at a higher temperature. The ODP sensor does keep you from killing yourself. Ours is in the shower
itself. I use a solar
fan and usually open the port as well.The vented heat from the unit dries the shower
stall. It does vent a fair amount of heat so it has a heat shield directly above and behind the unit. This isn't something you bury in a locker. It's not hard to take apart at all and has only a few things to service
a vent would require a cap for the flue under most sailing conditions so the ventless unit is a better choice. They only make one unit with the OPD sensor last I checked. We plumb hot water
to the head
, and galley
fixtures too but it's not like you can operate all of them at once and have really hot water. The propane
has a separate shutoff at the unit so you can just close it off.
