    hey guys
    since i put in my 400 w m.h i see im gonna have a problem with cooling my water come warmer weather ! i dont think the 2 fans are gonna be enough

    if i look at a chiller !
    can i put the chiller underneath the tank , next to the sump ? if so , how much space will i need ?? are there any parts of chiller that need to run outdoors ?
    my system is + - 1500 litres , so not sure what size chiller i would need ?
    what make should i be looking at ?

    thanks in advance

    clint

    Hi Clint,

    Aqua Medic and Hailea will be your best bet in terms of value for money. You can place the chiller beneath you tank as long as there is enough ventilation in that area. I think they recommend placing the chiller at least 15cm from the back and 10mm clearance on either side of the chiller. No obstructions in front of course:whistling:. Ideally you should try and install the chiller outside as it will be a lot more efficient. The chiller is one unit unlike your conventional air conditioning unit so the condensor and compressor are all in the same unit;)

    Let me just add, my chiller used to stand right next to my tank and I was sceptical at first about placing a R5000 unit outside. I have no regrets about it now that it's outside. The chillers make a bit of noise when they switch on so at least I can watch tv now

    thansk for the reply andreas
    will look into it
    if i place the chiller under my tank , it will be closed in with doors ! is this ok ?
    if i were to run it outside , i would have to run it a good 5-6 meters away and drill thru walls ! is that ok ?

    Sorry saw a spelling mistake and then just added another comment:) If you plan on closing the tank with some decent woodwork then I'll definately suggest you place the unit outside. You can place the chiller wherever it is best suited for you. Just get a flow pump that can push about 800 - 2000l through the chiller and you sorted;)

    My unit is inside the house and its not very nice during summer time due to the hot air exiting the unit at the back.I would go for the outside option if I were you.

    Glad you asked this, since I need the info as well :thumbup:

    Is that display tank and sump?

    I don't own one, but have heard only good things about the Hailea chillers.
    Someone correct me if I'm wrong, but the Hailea HC-250A would be perfect for your tank.

    I would go for at least the HC 500 as you don't want the chiller to overwork and constantly be on. This also obviously depends on where you reside and offcourse whether you plan on using fans to assist:)

    Interesting, that is almost double the tanks size in flow rate!
    Can you please explain a bit in more detail to me (noob)?

    the larger the chillers working capacity the more effectivley it will work..

    id also place the unit outside i had a scenario where the chiller was working well that the water cooled so well in the flat i was in it caused condensation on the front glass.. the fish were fine but i couldent live in the place.. put the chiller outside and have never looked back..

    thing about chillers , like heaters if the thermostat malfunctions , you often dont have time to remedy the situation - dead livestock is the result so what ever you do have a backup controller that runs the chillers so you have 2 thermostats working just for the inevitable time that one will fail which it will eventually.

    Hi, I'm not sure what you mean by "double size in flow rate"?The HC 500 is rated for about a 1200l system but this obviously depends on your lighting and equipment that will be used on the system. For a 1500l system I would definately go for atleast the HC500;)

    Agree with Leslie and Achilles on their posts

    Sizing a chiller accurately is not such an easy task. The Hailea and AquaMedic over simplify the task by giving a guideline on system volume and flow rate. For smaller and simple systems this will generally be fine but in reality you need to considers the amount of energy entering the system. This is added up as the amount of kW from all pumps, lights, powerheads, reactors, and so on. The flow rate also comes into play as energy is expended with water movement. Even the surface area open to the air can have an effect and is included in the rather intense equations! Then there is the obvious of room temp and incoming water temp.

    For the average aquarist all this will never really come into play. Its only for very large systems and industrial use. But good to know, even if the equations are impossible to understand.

    I have just bought 4 Aquamedic 250's for 4 different 800 L systems. I shopped around and found theses the best value. Also have had good experiences with AquaMedic equipment.

    Hi Clint

    Just saw this thread now.

    I'm running 2x 400w Mh on my system, I'm only running a Hailea HC500 at the moment. My volume is only about 600lts, so perhaps with your system being 1500Ltrs, I would go with a HC 1000, but you may get away with a HC 500 as you only have 1 Mh? (less of a heating effect with larger volume)

    Running the piping 6m is not a problem, just properly insulate with the foam like they use on the aircon piping.

    BTW, Isn't Aqua medic chillers made by Hailea or something?

    What i heard was that the two brothers use to own Aqua Medic and then decided to part ways. The other brother then opened up the Hailea company. I'm not sure how accurate this is, but either way both chillers are great quality:)

    Much like BT-4 and Tippmann(for those that might know).
