    Plus working through heat exchange, getting the primary liquid hot first, nothing like "instant" at all

    So how long do these systems take from power on to hot water?

    the one I posted ranged in price from 750usd to 1500usd... mattered the size desired. Looks like it is either a large heat exchanger or maybe a reservoir to me.... cept the hot water was a bit on a circuit maintaining the temp. Either way if reservoir or heat exchanger either one's ability to produce continuous hot water would increase as the size did. Must be why they sell various sizes.. each larger than the other from 4gpm to 6gpm.

    Coachgeo, what you posted is simply a heat exchanger (sometimes referred to as a "calorifier", I believe). That's a small part of the bigger system. You still need a heater (you can use engine heat if you wanna run the engine, or an Espar or Webasto heater for about $1500), a mix valve, and a whole host of other things to make a complete system.

    correct..... I posted that this was the case earlier. The other price quotes seemed to say that they too were NOT including the price of the Webasco or Espar. Their prices sound REAL HIGH for not have the heater included. PS. Used Webasco/Espars are out there.
