At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

What is the Wilo Yonos PICO1.0?

The Wilo Yonos PICO1.0 is a glandless circulator pump for heating and air conditioning that draws from just 4 W. Its EC motor controls the speed, and you set it with Wilo's green button and an LED display. It fits with a threaded connection in the heating or air-conditioning circuit.

What problem does it solve?

A fixed-speed pump moves the same flow even when your home needs less heat. The Wilo Yonos PICO1.0 controls differential pressure continuously, in variable mode for radiators or constant mode for underfloor heating. It therefore matches its power to the real demand of the system.

When you replace a failed pump, you need to keep the existing port-to-port length and thread. A model with different dimensions means altering pipework or fitting adaptors. The range offers 130 and 180 mm with three threads, so you can choose a model with the same dimensions.

Frequently asked questions

Which model do I need?

The one with the same port-to-port length and thread as your current pump, and an equal or higher nominal head. Check these three details on the pump's rating plate. If in doubt, send us a photo of the plate on WhatsApp.

What is the difference from the Wilo Yonos PICO without 1.0?

They are different ranges with different article numbers: the Yonos PICO1.0 uses 4248xxx numbers and the Yonos PICO uses 4215xxx. For the Yonos PICO1.0, Wilo describes two control modes: variable and constant differential pressure.

Is it suitable for underfloor heating?

Yes. Wilo recommends constant differential pressure (Δp-c) for underfloor heating and variable (Δp-v) for radiators.

Are unions included?

No. According to Wilo, the box contains the pump, the Wilo-Connector, 2 seals and the instructions. Unions are ordered separately.

What is the delivery time?

Shipped to order: we confirm the delivery time before preparing your order.

Q-Tech installation and support

Q-Tech offers three ways to work with your pump. The first is a pre-assembled plant room: we assemble, configure and test the plant room in our workshop, with safety and function tests.

The plant room arrives tested and ready to connect. The final connection is made by the site installer or Q-Tech, from one working day depending on the type and size of the plant room. See how it works on Advanced Pre-Assembly and in the workshop pre-assembly service.

The second way is for pumps installed by another company, and the third is for upgrading an existing system. In both cases, we first carry out a verification visit with the on-site Expert Technician by the hour service. We then quote for the work. In all three cases we can carry out the pre-commissioning check, remotely or on-site.

To choose a model or review a setting, book a remote technical call or message us on WhatsApp. See also our circulator pumps and Expert Technician services.
