High Loft Temperatures - water chillers

[Tentlover87]

I have a portable 12000btu air-con but will use 2.5kw hour and noisy as hell and with these led being so cool temps not been too bad.all I worry about is res temps

I made a wrap from bubble insulation for over the tent.but I always used 100mm celotex during the loft conversion.loft got up to max 35 during the heatwave but tent only got up to max 31 .running 8 and 6@ ec silenced revolutions

Very Nice, not so sure I would mount the fire extinguisher so high...

I got 4 automatic extinguishers in total in there dude.2 high one each side of tent then 2 over all the electrics .they give a 2m spread when there are set off so they give really good coverage of the worst did happen

Now that is some good precautions. Can you link me up with what you are using as this is something that does concern me being in the loft and all.

I see you have both a fully insulated loft and that cool bubble bag around the tent. Very cool and something I certainly want to move towards. Been recommended to me more than once to insulate the loft above the floor and I think this is something I definitely need to get sorted out before this time next year.

Thanks Buddy.

I have not even received it yet mate...

Be fecking winter by the time it arrives - luckily I can use it as a dehumidifier at least ;o)

Ice packs non stop lol

You could use some 2 litre pop bottles. Fill them up to about 4/5ths (to allow for expansion) and freeze them. They should last longer than those freezer packs.

Shoot. When I saw £715,866, I thought that was the price... then I scrolled down. Phew.

That's a good idea if you have a freezer large enough to cool them in the first place. My freezer is one of those under the fridge type deals and currently full of food the same age as the freezer ;o)

I got me some of those blue ice packs but to be fair since sticking a 30" RAM fan in the loft just to move the air around enough to allow the 'chiller to chill' has resolved the water temp issue. Now sits about 19℃-20℃ (my software shows the water temp out by a degree compared to the actual chiller for some reason - but still well within the ranges I need). While I would consider the chiller expensive it is actually a very handy item to have, my only regret is that I should have over specified it even more than I already did (res is about 50 litres so I got the 150 litre version - in hindsight the quicker it cools the less time it runs so get as big as you can afford).



I currently have both roof tiles in Extract so what I need is to get another inline fan (or two - which are also delayed!) so that I can stick one back on intake directly into the tent. This really keeps it cool but during the really hot days I had to adjust to cool the chiller down so reversed the intake into another extract directly from the loft.
