The espar.com web site has some positive comments, as anticipated.
Whats the opinion among SMB owners?
The D4 is the hydronic unit, or water heater. I gotta say, we're really impressed by it. We haven't had it long so I can't speak for reliability, durability etc,
It makes HOT water. We can make good instant potatoes with just the hot water, which go well with a steak grilled on the pit-to-go. It sounds like a jet turbine when it's heating up, which has it's own ... appeal
I just turn it on for a few minutes when I need it and then back off. The controller has lots of neat options like a timer programming etc to have it warm up at preset times but I haven't messed with any of that.
I have used it at 9000 feet with no issues.
