Alde Compact 3020 HE system

The Alde system always produces hot water if the water has been connected to the caravan and the system primed. It is not separate. The hot water facility on the panel allows to boost the water temperature for 20 mins (heating water stops circulating) in order to raise the temperature for showers. To reduce temperatures the mixer taps are used. If you truly feel it is too hot I would speak to Alde for advice. Meanwhile read up the instructions or frequently asked questions on the Alde website

Yes, the instructions do clearly state that you will always get hot water if the  Alde is powered and you have filled  the water system.  They explain clearly how the system works.

Note also that, if your caravan  MCB  panel has both a water heater and a space heater switch, one will be redundant when you have the Alde, so unless you know which is the redundant one, best leave them both on.

Sounds like in this case the water heater one is the one not used.

This will give you some ideas of how the system works.

You will always have hot water, why would you not want hot water? But only central heating when the pump is pushing hot water through the radiator pipes.

The temperature is set at a level which minimises the risk of legionnaires etc being present.

When we have our alde heating on during the night in our Conqueror 480 the pump will go on and off many times. The hum of the pump is minimal but we get loudish clicking noises (like pipes are expanding) each time the pump switches on - sometimes as many as 30 clicks. Has anyone else experienced this and how was it cured?

I would describe ours as more the pipes groaning, rather  than loud clicking. However, I don't think it can be cured. It is simply the pipes and joints expanding as they heat up. It is more noticeable at this time of year when the pump goes on and off a lot. In the colder winter months it is on a lot more, and the fluid foes not cool as much. I suppose reducing the heating temperature to 1 kw would cause the pump to remain on longer and therefore you would have less heating cycles of the pipes.

I have just bought a new van with Alde and like you still getting to grips with it. However am very impressed, and re noise ..I find it virtually silent.  No clicking or anything.  I can just hear the boiler when firing up with gas if everything is totally silent and I'm trying to listen to check it has started.

I have a 2015 Bailey Cadiz with Alde heating. I have just had my second service to be told that the blue coolant in the heating system only lasts two years and that the system needs to be completely drained and refilled with a red coolant that apparently will last for five years. Cost will be about 150 - 200 pounds.  I dont remember the salesman mentioning this when I purchased the van !

!! but I'm sure he did !!!

Our 2015 Lunar was fitted with 5 years fluid. Are they trying to get some extra money out of you?

Bailey certainly filled our 2014 Cadiz with the blue two year fluid. So I think the dealer is telling the truth. I assume Bailey must make a slight cost saving over using 5 year, which given the number of vans they sell must mount up. I don't think Alde even sell a two year fluid, so clearly their intention is that 5 year should be used,
