Anyone using a Espar B5 Hydronic heater ?

This is the gasoline version and the coolant heater not the air heater. If so I would like to hear your pros and cons. Mainly reliability and maintenance issues. Here is a link to the model

I have a D5 but haven't installed it yet. My understanding is the the reliability and serviceability is great though.

I can find all kinds of info on D5 user feedback but hardly any on the gas version. I was hoping someone on here would have one with some age on it.
