1. Water delivery system, comprising; at least one faucet device with a cold water faucet part and a hot water faucet part;a cold water line to the at least one faucet device;a tankless heater device for heating water having an inlet connected to the cold water line;a hot water line having a first portion running from an outlet of the tankless heater device to the at least one faucet device and having a second recirculating portion running from the at least one faucet device to an inlet of the tankless heater device; anda circulatory pump arranged in the second recirculating portion of the hot water line;wherein the circulatory pump has a prefixed first performance level and a prefixed second performance level;wherein the prefixed first performance level causes a first water flow rate in the hot water line which is below a flow rate threshold value for operation of the tankless heater device; andwherein the prefixed second performance level causes a second water flow rate in the hot water line which is higher than the first water flow rate and above the flow rate threshold value of the tankless heater device. 2. Water delivery system in accordance with claim 1, wherein heating operation of the tankless heater device is flow rate controlled. 3. Water delivery system in accordance with claim 1, wherein the circulatory pump has a third performance level at which the flow rate in the hot water line is substantially zero. 4. Water delivery system in accordance with claim 1, wherein the circulatory pump comprises a control device which switches between the first performance level and the second performance level. 5. Water delivery system in accordance with claim 4, wherein the control device is coupled to at least one of (i) at least one sensor of the circulatory pump, and (ii) at least one sensor of the tankless heater device, wherein depending on the received signals from the at least one sensor either the first performance level or the second performance level is switched to. 6. Water delivery system in accordance with claim 5, wherein the at least one sensor is a temperature sensor. 7. Water delivery system in accordance with claim 5, wherein the circulatory pump comprises a thermostat. 8. Water delivery system in accordance with claim 6, wherein the control device switches from the first performance level to the second performance level when a temperature measured by the at least one temperature sensor is or falls under a first temperature threshold value and switches from the second performance level to the first performance level when the measured temperature is above or passes a second temperature threshold value. 9. Water delivery system in accordance with claim 8, wherein the second temperature threshold value is higher than the first temperature threshold value. 10. Water delivery system in accordance with claim 8, wherein a timer is provided for controlling the time between switching processes. 11. Water delivery system in accordance with claim 1, wherein the circulatory pump comprises an interface device for signals or data from the tankless heater device. 12. Water delivery system in accordance with claim 1, wherein the tankless heater device comprises a flow meter. 13. Water delivery system in accordance with claim 1, wherein a time of the day timer connected to or being part of the circulatory pump is provided for setting a third performance level which is a zero flow level. 14. Water delivery system in accordance with claim 1, wherein the tankless heater device comprises an interface device for providing data or signals to the circulatory pump. 15. Water delivery system in accordance with claim 1, wherein the tankless heater device comprises a control device for setting or adjusting at least one of the first performance level and the second performance level at the circulatory pump. 16. Water delivery system in accordance with claim 1, wherein a flow control valve is arranged in the hot water line between the circulatory pump and the tankless heater device. 17. Water delivery system in accordance with claim 1, wherein a connection between the hot water line and the cold water line is provided. 18. Water delivery system in accordance with claim 1, wherein the second portion of the hot water line is a recirculation line for hot water. 19. Method for making hot water available in a domestic hot water installation, said domestic hot water installation comprising a tankless heater device, a hot water line connected to an outlet of the tankless heater device, a cold water line connected to an inlet of the tankless heater device, at least one faucet device connected to the cold water line and the hot water line, and a circulatory pump arranged in a recirculating portion of the hot water line that runs from the at least one faucet device to an inlet of the tankless heater device, comprising: setting a prefixed first performance level and a prefixed second performance level at the circulatory pump, wherein the first performance level causes a first water flow rate in the hot water line which is below a flow rate threshold value of the tankless heater device and wherein the second performance level causes a second flow rate in the hot water line higher than the first flow rate and above the flow rate threshold value of the tankless heater device;switching to the first performance level of the circulatory pump for providing a low speed circulation of hot water when the temperature of the hot water in the hot water line is above a temperature threshold value; andswitching to the second performance level when the temperature is below a temperature threshold value. 20. Method in accordance with claim 19, wherein the temperature in the hot water line is measured at at least one of the circulatory pump and the tankless heater device. 21. Method in accordance with claim 19, wherein heating operation of the tankless heater device is flow controlled.
