The Return Pump

[TurboBrick]

So far I've got my tank my lights and a rodi unit. It is slowly coming together.

 

I will be getting a return pump for my next tank purchase.

 

I've listed the return pumps I'm looking at in order of price:

 

Ehiem compact+ 3000. Listed at 66 watts

 

Tunze Silence 1073.020. 30 watts

 

Sicce Syncra 2.0. 43 watts

 

Jebao DCT 3000. 25 watts

 

 

I was thinking of getting the Jebao as a back up to keep in storage as it is the cheapest.

 

I am trying to keep the wattage as low as possible because I have no ac and am trying to avoid running a chiller.

 

Keeping that in mind I am leaning towards the Tunze silence pump as I have read that the Jebao have a tendency of failing.

 

Is there something else I should be looking at when choosing between these pumps?

i agree on having a back up. we are hard on pumps. water changes and all the on/offs to say the least. i had 2 sicces go out in a year. so my opinion may be biased, but i have cheaper pumps and dry backups waiting for when they fail. if i could fit the ecotech vectra i'd do it in a heartbeat. it seems the really expensive pumps are good but the middle range price doesnt have that much benefit tot me.

If wattage and temp are big considerations, you probably prefer one of the DC pumps. They will typically be more efficient, though with the exception of the Jebao will possibly be more expensive up front. I think all the DC pumps allow speed control, and some will also allow variable Apex control if that's of interest.

I thought wattage and temp were a direct correlation.

 

Besides being lower wattage, is there something about the dc pumps that make them put off less heat into the water?

Wattage and temp are closely correlated for sure, but there are a couple of differences between the AC and DC pumps.

 

Part of the wattage consumed by a DC pump will be in the transformer and the controller, neither of which is contributing its heat to the water. (some manufacturers list the transformer wattage separately, though)

 

As you indicated, DC is generally lower wattage, because GPH flow per watt is generally higher in a DC pump, meaning for the same desired flow rates or head pressure, you will be consuming fewer total watts and adding less total heat to your system.
