Another Alde Questions

RCB

Consider, please, this scenario. Cool night but expected to warm up in the wee hours. The Alde is set to a comfortable temp and is happily heating the T@B. As it warms up there is no further call from the thermostat for any heat. Does the system shut down, or just sleep ? Does it draw any electricity or propane under this condition ? Can it be left on in such conditions ?
Thanks.

The Alde will continue to provide hot water, but the heat circulation pump will not cycle on when the set temperature is less than room temperature.

I agree with klenger.  Your Alde continues to draw power for the display (AC vs 12 v) and to heat the water (AC, 12 v, or lpg).  Just leave it on if you want to always have hot water or I know some folks in the summer, turn off the Alde and turn it back on when they want hot water.

There is a slight electrical draw to maintain the control panel and associated electronics,   but it should be negligible

I'll add that if the Alde is on--even if it's not circulating heat to the cabin--the unit will be warm. Some people might appreciate a mattress that radiates heat, but I do not!

Alde power use from the Alde Knowledge Base Page:

There are two functions in the Alde Compact 3010 that draw >0.1 A of current from the vehicle's 12-volt battery. The combustion fan which supplies the burner with air (≈ 0.4 A), and the circulation pump that circulates the hot glycol in the heating system (≈ 0.2 A). 

So normally the heating system draws ≈ 0-0.6 A when running on LPG and ≈ 0-0.2 A with a 120 V immersion heater. 

As a maximum, the boiler draws 1.9 A for about three seconds when starting on 12 V DC.
