ᐅ Circulation pump – 10 seconds until hot water arrives

Hello,

we have a circulation pump, but it takes 5-10 seconds for hot water to arrive. Is that normal?

There are several types of circulation pumps:

1. Time-dependent circulation:
Circulation occurs at fixed intervals over a specified period and duration. Sometimes it is interrupted when a certain temperature is reached in the circulation "return line."

2. Demand-controlled circulation:
The circulation pump switches on for a certain time when the water circuit is opened, to deliver warm water faster to the outlet.

It seems like you don’t have any circulation running at all?
How is your pump controlled?

The pump is simply plugged into the socket. Our plumber suggested buying a timer switch to turn it on and off based on time.

It is a Wilo Star-Z NOVA.

When the pump is plugged in, it consumes 5 watts. When I draw water at a tap, the consumption briefly increases to 230 watts.

So the pump is constantly plugged into the socket?

Do you have a domestic hot water storage tank?

Yes, but time-controlled, turning on three times a day for 30 minutes each.

Yes, 300 liters (79 gallons) storage.

I just received the following response:
A recirculation line must be connected at some point. It cannot be connected directly at every tap. Therefore, a small section of pipe will remain without recirculating water. If you have had hot water immediately before, the tap must have been used at least once before. There is no other technical explanation.
