killkyo512 Posted October 14, 2017 Share Posted October 14, 2017 I'm relatively new in this hobby, just like to check. How much savings do we really see between a chiller and compressor in terms of electricity? How much heat will a compressor generate? I'm currently using a 66s chiller for a 422, I know it's under size and am looking at a change by don't know which way to go towards.

Solo77 Posted October 15, 2017 Share Posted October 15, 2017 Search past threads. Savings can be calculated(if u monitor the Kickstart and stop per day) but will be estimation. There are other factors like heat emission from PUMPS. Generally, drop in coil has more advantages if price is not an issue.

SRC Member christan1959 Posted October 15, 2017 SRC Member Share Posted October 15, 2017 Both are equally efficient. Choose a drop-coil only if exhaust heat or noise is an issue for u Quote Link to comment Share on other sites More sharing options...

SRC Member christan1959 Posted October 16, 2017 SRC Member Share Posted October 16, 2017 U can locate compression away from tank - e.g. on roof top, outside balcony etc Quote Link to comment Share on other sites More sharing options...

SRC Supporter SubzeroLT Posted October 19, 2017 SRC Supporter Share Posted October 19, 2017 I have a compressor next to my 5ft tank (850l). It takes about 20-30min to cool 1degC. Based on my tracking, it runs a total of about 4-5hrs per day. It does get quite windy/warm when the compressor is on since all that heat is now removed in a shorter time. But i'm sure a chiller takes a longer time to cool & will overall run longer & more expensive. Here is the bill cost : Quote Facebook : https://www.facebook.com/mysliceofnature/ Link to comment Share on other sites More sharing options...

SRC Supporter SubzeroLT Posted October 19, 2017 SRC Supporter Share Posted October 19, 2017 How many horsepower is it? It’s 1hp. Calculations correct?

SRC Member christan1959 Posted October 20, 2017 SRC Member Share Posted October 20, 2017 So for proper comparison, you have to use a 1hp inline chiller on the same tank. See how fast it brings the water down by 1 degree. Quote Link to comment Share on other sites More sharing options...

That's really worth considering. Now is to do the calculations on how long it takes to break even compared to a chiller. Quote Link to comment Share on other sites More sharing options...
SRC Member christan1959 Posted October 20, 2017 SRC Member Share Posted October 20, 2017 Drop in coil easily 50% costlier. That's why your first consideration is whether noise and heat are serious issues for you. Quote Link to comment Share on other sites More sharing options...

Actually I'm looking at economical sense now, as my tank is sitting in an open area near my door, most heat will not stay, noise wise, so far using chiller haven't been too noisy for me.

SRC Supporter SubzeroLT Posted October 20, 2017 SRC Supporter Share Posted October 20, 2017 A new set of compressor/coil/controller/installation is roughly around $1400. 2nd hand set can be found occasionally in the forums typically between $400-$900. Then need to factor in about $250 installation for the 2nd hand set. Quote Facebook : https://www.facebook.com/mysliceofnature/ Link to comment Share on other sites More sharing options...
SRC Member Komerider Posted October 21, 2017 SRC Member Share Posted October 21, 2017 I think if u r looking at long run TCO with equipmemt cost added in , then the electrical efficiency rating is also impt. I run the teco tk500 directing exaust air away thru a vent which the tk series were designed with. By ensuring warm air doesn't hit back at the coils the chiller is also more efficient. The tk500 consumes less power supposedly but if it conks fast then its still costly. So reliability (brand n trackrecord), a well ventilated area ( compressor can prob be placed somewhere windy) and right sizing the equipment according to the tank size all have to be balanced up I guess.

Plasticgoat Posted October 29, 2017 Share Posted October 29, 2017 I got sick of hilea chillers water tank rusting n leaking. I also find that you can't really service chillers much. I currently use daikin 1hp chiller. Super reliable any air con service person can service it. The downside is the hot air it emits is rather warm. I would suggest you mount the compressor far away. Outside your unit if possible. 1 Quote Link to comment Share on other sites More sharing options...
