You can't answer this question without knowing the temperature of the cold water. In hot weather
with good warm water in the tanks
, you need very little hot water from the calorifier to make a nice warm shower. In very cold weather
, it's different.
FWIW, and that's little, because your case will be different, we have a 32 liter calorifier (downsized from original 50 liter), and we can normally get 3-4 navy
showers out of it with pretty cold water in the tanks
. The last one will be lukewarm.
A trick we use sometimes at the end of a cold passage
where the whole crew wants showers at once --
Start up the generator
, turn on the 1.5kW immersion heater
. Fire up the Eberspacher. With TWO heat sources going, the hot water is practically endless.
