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.

Compact recirculation pump for household hot water

The DAB VORTEX BWO 155 R circulates domestic hot water round a home's return loop and only runs when needed. It has a brass body with an R ½" female thread, 80 mm between ports, delivers 1.3 m head and 950 litres per hour and draws 2.5 to 9 W. At Q-Tech we fit it as a replacement and in residential plant rooms.

What is the DAB VORTEX BWO 155 R?

It is a recirculation pump from Vortex, the German manufacturer in the DAB group. Its spherical rotor runs on a single sealing ring between motor and body, which makes it easy to clean and replace. It comes with an insulation shell and dry-running protection.

What problem does it solve?

In a home with a hot water return, a pump running day and night wastes electricity and cools the cylinder for no reason.

The BWO 155 R module decides when it runs: the ERT stops and starts on return temperature (Δ 7 °C), the ZM follows the times you set and the ZM KT combines a timer with a fixed 46 to 55 °C thermostat. So it runs fewer hours on very little power.

  • Designed for homes: 1.3 m head is not enough for a building's return loop.
  • This listing is the R version (½" female thread). The V version, with check valve and shut-off valve, is a different item.
  • The photos show the R version in front and the V version behind, with the same module.

Frequently asked questions

ERT, ZM or ZM KT?

The ERT if you want it to run by itself on temperature; the ZM if you prefer set times; the ZM KT if you want set times and also want it to stop once the return is hot.

Can I replace just the motor?

Yes. The brass body stays in the pipe and the motor with its module is replaced separately. Ask us for the part number.

What is the delivery time?

It is in stock at our warehouse; if none were left, we would order it urgently and tell you the lead time.

Who should install it?

Qualified professionals must make the plumbing and electrical connections.

Q-Tech installation and support

To replace or install the return pump in your home, book an on-site Expert Technician by the hour; if you are unsure which model fits, request a technical call. In new builds we fit it in a pre-assembled plant room, which arrives tested and ready to connect. More equipment in DAB circulator pumps.
