Alde system All Alde heating and hot water systems work in the same way as a rule. They are split into two parts. Hot (domestic) water for your taps and shower. And a semi sealed solution of 50% water and 50% salt free anti freeze. This solution is pumped through pipes that run around the edge of your van. You then control both systems from a control panel. The heating system has various bleed valves located around the van and an expansion bottle that you top up from time to time. There are a couple of things to remember with this system. It needs to be recharged every 5 years and it can take up to an hour to fully heat up.  Please remember that any anti freeze is lethal to animals or humans if consumed.   © Art By Paul 2000-2018    To understand more about power, hookups etc please view the POWER page. Heating (radiators) Right, we will begin with the heating controls. They are really simple to use. Just tap on the “+” to increase the tempature or tap the “-” to lower it. Couple of things to remember. The lowest you can go is 5c and the highest is 30c. Please be aware that if your control pael is set to “OFF” on the power settings (image 3) and the gas icon is off (not green) then you will have not heating. And it also takes up to an hour to fully heat up. Hot water The Alde boiler holds about 10 litres of water and is basically a big kettle. Once you have primed the water system you can switch the water heater on. So assuming you have water already coming from any hot tap in your van you do exactly as you did before. Tap the “+” to make it hotter or the “-” to make it cooler. Now depending on your control panel you will have several options. Some panels will let you select the water to cold/50c/70c. Others will only allow cold or 70c and some will only allow you to have either 40c or 70cbut no off option. So lets just assume you have 0c/50c/70c on yours. Tap the “+” once to set the hot water to 50c. Now depending on what power source (img 3) you selected, your water will start heating up. Please note that this will normally take around half an hour or more. Power source As with most Alde systems you can run the complete system on mains hookup (240ac), gas (propane is best) or even both at the same time. So lets assume you are wild camping (such a strange phrase) and wish to use only electric (240v) to heat the van and water. You simply press the “+ or “-” buttons to select between 1KW/2KW or 3KW. Most UK sites work on 2KWso we will select 2KW. Ok so assuming you set the heating to 20c, the water to 50c and the power source to 2KW as shown in the pictures (left) your system will turn the heating on if your van gets colder than 20c. Your water will automatically heat to 50c and maintain this temperature.  Now lets assume while you had all this set up and it was running you also turned on an electric kettle. As a rule you would pop the sites fuse box. However what the Alde system should do is detect the sudden rise and switch off the hot water (boiler) until the kettle has boiled If you had the gas switch on (i.e green) and exceeded the set KW, the boiler would switch to gas instead. The easiest way to set this up is follow the following guide. On a hookup that allows up to 2KW (select 2KW and gas off) On a hookup that allows up to 1KW (select 1KW and gas off) You wish to use gas and 2KW electric (select 2KW and switch gas on) You wish to use gas and 1KW electric (select 1KW and switch gas on) NOT on a hookup  (select gas and set source (img 3) to OFF) If the gas icon is BLUE, the gas is switched off and if it is green, the gas is switched on. 50c Heating (radiators) Right, we will begin with the heating controls. They are really simple to use. Just tap on the “+” to increase the temperature or tap the “-” to lower it. Couple of things to remember. The lowest you can go is 5c and the highest is 30c.
