Pressure tank or tankless water system?

[Noel M2]

Hi,

Does anyone know if a "tankless" water pump set-up is more costly to operate compared to one that include a pressure tank?

We have one of those Grundfos water pumps that does not require a separate pressure tank (I realize that there is at tiny tank built into this pump). I wonder if it makes any difference in power consumption between a setup that includes a larger pressure tank or this on-demand system (assuming the motors are similar in horsepower and efficiency).

I hope the question is clear.

Thanks in advance,




Noel
