Guide

How to check if ref. 59725008 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Check the label on the pump: it should say Grundfos UPS15-50 V4 CIAO and the P/N 59725008.
Compare the code Radiant 24052LA (in the breakdowns: "CIRCULATOR UPS 15-50 CIAO 3WAY"). The PCB 0843RAD only indicates the production.
Don't confuse it with other Radiant pumps: the 24056LA (RS 15/6-3) or the 24022LA (Wilo RSL15/6-3).
Check that it has three speeds and the same hydraulic body, impeller, electrical connection, and fixings.
If they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.

Diagnosis and fault codes

Symptoms that require diagnosis in the radiant 59725008

Common symptoms and faults

01
Cold radiators even though the boiler ignites the flame
Cause: it is associated with this pump. Check if the circulator is spinning and moving the water.
02
Buzzing, noise or vibrations
Cause: They may come from the pump; check if the rotor spins freely.
03
Stuck rotor after a long stop
Cause: it is mentioned after the summer break; suspect the pump if it does not rotate.
04
Water leaks in the pump body
Cause: Check if it is leaking from the body or the joints.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.

Before purchasing

It is advisable for a technician to change the circulator: the pump operates at 230 V and is connected to the boiler's water circuit.

Not compatible or excluded from origin: Radiant RMAS 24 MAXICOMFORT version GB — Its official list provides another pump: Wilo 24022LA
Do not confuse: 24056LA — Circulator RS 15/6-3-KU-CLF-61, in the same list as the RKA 25 2V — It is another model of pump, not the UPS 15-50.
Do not confuse: 24022LA — Wilo circulator RSL15/6-3-CLF6 from the RMAS 24 MAXICOMFORT version GB — Another pump, from another version of the boiler.
Do not confuse: N47G005M0 — Fagor Pump FEE-24MA N (UP 15-50 A0 /FG) — It is from another Fagor boiler; this one uses 59725008.
According to the manual, 24052LA appears as "UPS 15-50 CIAO 3VIE", "3V." or without suffix; it is the same Radiant code.
Verified identity in (official breakdowns Radiant, Área54): 59725008 = UPS 15-50 V4 CIAO = Radiant 24052LA. The boilers to be consulted each have 1 origin, except for the RMAS 24 E MAXICOMFORT, which is unconfirmed.

Frequently Asked Questions

Frequently asked questions: radiant 59725008

How do I identify this pump?

On the PCB is the type UPS15-50 V4 CIAO and the P/N Grundfos 59725008. Radiant lists it as 24052LA («CIRCOLATORE UPS 15-50 CIAO 3VIE») in the official breakdowns of the RKA 25 EKOFLUX (pos. 2) and the RKA 25 2V EKOFLUX 2 VIE (pos. 3). The PC 0843RAD indicates production and does not replace the P/N.

Is it compatible with my Radiant RKA 25 EKOFLUX or RMAS 24 E MAXICOMFORT?

According to the official parts list from Radiant (A011A432G231, rev. 00), the RKA 25 EKOFLUX MET IT DT2-CBD has the circulator 24052LA / 59725008 in position 2, quantity 1. It is a single source. For the RMAS 24 E MAXICOMFORT MET IT 3S-DT, we have not been able to verify its spare parts list, and the RMAS 24 MAXICOMFORT version GB has a different pump, the Wilo 24022LA. Compare the 24052LA and P/N 59725008 with your pump or send us a photo of its label and the boiler's control board from Contact. You can also call 911 17 77 77.

Is it compatible with the Fagor FE 25 NOX 1N?

Yes. Confirmed: for the FE 25 NOX 1N, and also for the FE25NOX-1N and the FE-24 NOX. Another list gives for the FE 25 NOX the code Radiant 37029LA without specifying what the part is: always compare with yours.

What is the difference between 24052LA, 24056LA, and 24022LA?

They are different pumps from Radiant. The 24052LA is the Grundfos UPS 15-50 CIAO 3VIE (59725008). The 24056LA is the circulator RS 15/6-3-KU-CLF-61 from the RKA 25 2V list. The 24022LA is the Wilo RSL15/6-3-CLF6 from the RMAS 24 MAXICOMFORT GB.

What do 59725008, 24052LA, and 0843RAD mean?

59725008 is the P/N from Grundfos, 24052LA is the spare part code from Radiant, and 0843RAD is the production code (PC) marked on the plate. To order the pump, use the P/N or 24052LA.

Is it a single-speed pump?

No, it has three: 50 W (0.21 A), 55 W (0.25 A), and 65 W (0.29 A), at 230 V and 50 Hz, according to its PCB. The technical sheet of Área54 confirms 230 V · 50 Hz, IP 42, TF 95, class H, and a maximum pressure of 0.3 MPa (3 bar).

Can I install it myself?

To confirm: It is advisable to have a technician install it: it operates at 230 V. It is not recommended to install another Fagor pump, the FEE-24MA N (N47G005M0), without experience because it requires draining the heating circuit.

What reference corresponds to the part?

P/N 59725008 is the Grundfos number; 24052LA is the Radiant code that both parts associate with the circulator. PC 0843RAD remains as the production marking.

Is the pump compatible with the Fagor FE 25 NOX 1N?

Yes. FE 25 NOX 1N appears in the Compatibility column of INVENTARIO ALFONSO. The parts lists also identify this pump in two Radiant variants: RKA 25 EKOFLUX MET IT DT2-CBD and RMAS 24 E MAXICOMFORT MET IT 3S-DT.

What does the maximum pressure of 0.3 MPa mean?

It corresponds to 3 bar, the marked limit of the circulator; it is not a recommended filling pressure.
