Hydro hot and aqua hot are the same, just different years. They have several models, some have one electric element, some have two.
Hydro Hot was the entry level system from Vehicle Systems. The better models were called Aqua Hot. They changed their name to Aqua Hot a few years ago and call ALL their products Aqua Hot now. You go by the model number to determine what is entry level and what is a higher line model now. Oasis is another brand of Hydronic heating. LP powered Hydronic heating is not as efficient as Diesel powered Heating. BUT, if the unit has NO Diesel, then you have to go with a LP/120 Hydronic heat system. LP powered systems use a lot of LP.
