Alde wet heating system

Melmodz, don't fotget to fully recharge your water system on your next trip out, so that water is running from all taps on the hot setting, before switching on the heating &/or water heater.

Alde systems heat tap water through a second water jacket. Unlike the old systems where heating an empty tank would cause the system to trip, you don't need to fill the hot water jacket in order to run the heating.

as with the Truma Combi....heating with an empty water cylinder is perfectly fine.

Not necessary with the Alde system.

Surely one must ensure that there's water in the system before switching on the water heater boost.

Been reading this thread,  interesting.  We have been looking at new caravans, wondered if the Alde system of heating was worth the extra money? Looked at two vans one with Alde and one with blown air.

Having used a van with the Alde system for some 8-9 years now, we would say it is the better system.

Yes, the thing is, you don't have to have water in the boiler to use the heating system with Alde and Truma Combi. If you want hot water aswell then obviously you need to fill the boiler.

No, Just raises the temperature in the system. Turns the pump off and so circulation. Achieves nothing though

From what I recall, the Boost function just gives priority to the water over the heating but the temperature is the same. We never found it useful.

But what if you don't want the heating on, only hot water relatively quickly?

Not so, it raises the temperature of the HW by about 10 degrees.

Very useful when showering, gives you hotter water to mix with the cold, so a longer shower.
