Hey Rick.
My Yamaha 30 has an Espar forced air unit. Which I would like to replace.
It works alright, but takes a while to get heat output, is somewhat noisy (fan, furnace & fuel pump tick-ticking), is noisy to others at anchor & uses battery.
Others seem fine with the noise issue, but I like quiet and hate not knowing what it's doing to the battery level.
When I can get around to it, I'll be going to the Dickinson Newport. Like the idea of the warm flame look, would be able to get immediate heat to my hands on a wet day, would get more heat into the boat quicker, and I could direct the heat where I wanted to with fans.
Still trying to decide whether diesel or propane. I've got propane on board with solenoid shutoff, but the stove would be up front close to the diesel tank. Lots of plumbing required with diesel, and/or daytank. Propane would mean running long line, but I'm thinking it may be the way to go.
Anyway, that's my 2 cents.
