If you’re not planning on using the Alde until next year –

you can leave it in there. Then flush the system before first use next year. Antifreeze itself will not ruin the hot water tanks, it’s when you have antifreeze in there and you turn the system on.

If you want to use heat in this winter

To remove it you will need to flush all the lines with fresh water – opening all the faucets including the hot water faucets.

You would then open the yellow flip up valves underneath the bed for the Alde hot water tanks, until you see fresh water coming out of the bottom of the unit.

Its going to be a little bit of a process – but you will need to ensure absolutely no antifreeze is in the Alde tanks by flushing the system if you want to use the interior heating during the winter.
