FAQ

The burner in the heater works in two stages. Small heat demand – the lowest power stage (275 g/h propane) and large heat demand – the highest power stage (460 g/h propane).

The heater is ingeniously designed to select the electric cartridges as the primary heat source if 230 V is connected to the vehicle and if the electric cartridges are activated on the control panel. If this is not sufficient, the LPG burner will start automatically (if activated on the control panel).

Keep in mind that it is possible to choose between and prioritise between electricity/gas energy sources.

The short answer is that the Alde heater draws about 1 A for basic functions/operation of the heater. A more detailed answer follows below.

There are two functions in the Alde Compact 3030 that draw more than 0.1 A current from the vehicle’s 12-volt battery. The combustion fan that supplies air to the burner (≈ 0.4 A), and the circulation pump that circulates the hot glycol fluid in the heating system (≈ 0.3 A).

So normally the heater draws ≈ 0-0.7 A in LPG operation and ≈ 0-0.3 A with 230 V electric cartridge.
At maximum, the heater draws 1 A for about three seconds when starting at 12 V DC. In 230 V immersion heater operation it draws ≈ 4.5 A on 1 (1 kW), ≈ 9 A on 2 (2.1 kW) and ≈ 14 A on 3 (3.2 kW).

The control panel is probably set to constant operation of the circulation pump, which means that all power goes into the heating system.

Operating instructions for the control panel and heater should be included in your vehicle. But you can find these under > Manuals.

Simulator: You can test all control panels here.

Quick guide for Alde Control Panel 3030

Varies greatly, depending on the inside and outside temperature, the number of people, the design of the heating system and the insulation of the vehicle. Whether you run on 230 V electric cartridge only (1, 2 or 3 kW) or gas only or both electric cartridge and gas at the same time. This means that the power can vary from 1 kW to 8.7 kW. Generally, the room temperature in the vehicle reaches a comfortable level within an hour, if both gas and electric cartridge are activated.

All models of the Alde Compact 3030 are equipped with a 3 kW electric cartridge.

In the Alde Compact 3030 Plus you have unlimited hot water, as long as there is water in the fresh water tank.

The standard Alde Compact 3030 has a hot water tank with a volume of about 10 litres of hot water at >50°C. When the hot water is mixed with cold water (approx. 10 °C) to the normal user temperature of approx. 38 °C, this results in approx. 12 litres of hot water every 30 minutes.

The colder the water, the longer it takes to heat up. If 230 V electric cartridge is used instead of gas to heat the heater, the capacity is slightly reduced. The “extra hot water” function on the Alde control panel raises the water temperature to > 65°C for 30 minutes. This means ≈ 15 litres of heated water, mixed and ready.

Set the desired room temperature to well below ambient on the control panel. As the Alde Compact is a combination boiler, it heats both heating fluid and hot water simultaneously. If the desired temperature is set about 5°C below the ambient temperature on the control panel, the heating fluid will not circulate to the convectors because the circulation pump will be stopped.

For 3000/3010/3020: Under the pump operation symbol on the control panel, THERM must be activated (green).
For 3030/3030 Plus: Auto must be indicated at the pump.

Make sure the heating system is vented. Make sure that ventilation slots in furniture are not blocked. Use maximum power on the electric cartridge and gas during heating. Avoid running hot water for showers etc. until the vehicle is heated. Do not let the temperature in the vehicle drop below 10°C during the day/evening.

You can use both gas and electricity at the same time, giving you a higher maximum power output (up to 8.5 kW).

Yes, it is possible to run the heater without fresh water. However, you should not run the system without glycol.
