Need advice on chiller. It's kicking in more frequently but for a

[kaykay]

Hi guys.

Some background info first.

1. Hailea 66a chiller (1/4 hp)

2. Newjet 1700L/h pump from last compartment of ios to chiller (2ft lower) and back to display tank.

3. Tank volume 90L.

4. I bought 12/16 Eheim double taps, as I initially wanted to use my Eheim 1250 return pump (12/16 fittings) for this purpose, but this pump I found underpowered for this chiller. The new pump uses 16/22 fittings, so do the chiller, so I used step up/down connectors.

On the first day of this setup, The chiller is kicking in after 40 mins, for 7 mins each time.

Now the chiller is kicking in after 23 mins, for 4 mins each time.

Question.

1. Is it bad for the chiller to kick in so frequently, but for a shorter working time?

2. The energy consumption is roughly the same for either way. But does it use more power at the kicking-in moment?

3. Shall I leave it as it is, or try to get back the original timing on the first day? I think by changing the hoses and fittings to 16/22, I will be able to get a better flow, and thus longer time to cool the reservoir and thus, longer kicking in period and vice versa.

Thanks.

Problem solved.

I changed all the fittings and hoses to 16/22 sizes.

Flow rate is improved. I have even disconnected the 2nd return pump.

Now, the chiller is 12 mins on, about 100 mins off.

By this timing ratio, the chiller is functioning less per min. Thus electricity $ is minimized.

Thanks for sharing.

I'm using a external temperature probe and it kicks in for 33-35 minutes (27deg to 25deg), and off for roughly 3 hours.

Wow, that's a long rest time for the chiller. Btw, how big is your water volume that it can sustain the temperature for such a long time?
