Browse Forums Heating, Cooling & Insulation 1 Nov 19, 2008 9:38 am I have two quotes for my evap
One is the Brivis contour L53 installed to 8 points with .6 ducting for $3750 The other is the same model and ducts but with 1.1 triple insulated ducting but it is $4800 Is it worth the extra $$$$ to have the better ducting? Re: .6 ducting vs 1.1 ducting does it matter 2Nov 19, 2008 1:10 pm for evap cooling i would say no.
we did a little experiment here. took a 100w light bulb and put it in a r0.6 duct for a day. at the end of the day you could feel heat on the outside of the bag. we did the same thing with a r1.0 duct and you couldn't feel anything on the outside. we took temperature measurements etc but it was years ago... so in short - the better the insulation the more heating/cooling you keep in your ducts. but evap cooling moves so much air so fast and so cheaply that it is not worth spending 1000 more Dynamic Heating & Cooling - http://www.DIYheating.com.au DIY Ducted Heating & Cooling Systems DIRECT to the public Re: .6 ducting vs 1.1 ducting does it matter 3Nov 19, 2008 1:30 pm Penny I have just booked my evap cooler and most places will upgrade you at no charge. Just tell them that you want it.
$4800 sounds very expensive for that unit. You can get the breezeair for cheaper with the R1.1 ducting.

If the sun hits a window directly it doesn't matter too much if it's double or single… 1 12645 |
