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 Domusa Dual Clima R?

The Domusa Teknik Dual Clima R is a monobloc air-to-water heat pump for heating, cooling and DHW that runs on R32 and delivers flow temperatures of up to 60 °C. The whole refrigerant circuit sits in the outdoor unit. The connection to the house is hydraulic only.

Three versions: standard, EC and RT

The standard version has its control panel inside the home and accepts the Domusa iConnect module for control from your phone. The EC version works with the Easy Connect module, which includes iConnect as standard and talks to the outdoor unit over Modbus. Easy Connect handles the buffer tank sensor, outdoor sensor, humidity sensor, SG Ready, system circulator, cascade and energy meter.

The RT versions (16RT and 19RT) run on 400 V three-phase and have no connectivity option, according to the Domusa Teknik price list.

What problem does it solve?

A home moving away from oil or gas needs heat in winter, cooling in summer and hot water. Installing three different appliances multiplies connections, control panels and maintenance in the plant room.

The Dual Clima R provides all three services from a single unit rated class A+++ at 35 °C. An output chosen without a heat-load calculation leads to short cycling or a lack of heat on cold days. That is why Q-Tech reviews the home's demand before recommending a model.

The 19R and 19RT models include the backup pump kit, according to the Domusa Teknik price list.

Compatibility and limits

  • The system needs a minimum water volume of 35 to 95 litres depending on the model; below that, Domusa specifies a buffer tank.
  • Domusa requires a water filter on the heat pump return, fitted before the circuit is filled.
  • For long winter power cuts, Domusa offers the anti-freeze drain valve or glycol in a short circuit with a separator tank.
  • The EC versions only work with the Easy Connect indoor module.
  • The RT versions do not accept the iConnect module.
  • Domusa includes commissioning in its price, excluding travel.
  • Installation and certification require a licensed installation company.

When this product is not the right choice

  • If the system needs flow temperatures of up to 75 °C or you prefer a natural refrigerant, the Dual Clima HT Pro runs on R290 up to 75 °C.
  • If you only need domestic hot water, a dedicated DHW heat pump with a built-in storage tank is simpler.
  • If there is no room for an outdoor unit, the Domusa NanoClima 4 and NanoClima 4 HDX 135 are installed indoors, with no outdoor unit.

Frequently asked questions

Which model do I need?

It depends on the home's heating demand, not just its floor area. Send us the area, insulation and emitters on WhatsApp and we will recommend a model.

What is the difference between the Dual Clima R and the Dual Clima R EC?

The outdoor unit has the same data. The R EC has iConnect built in and needs the Easy Connect module, which adds sensors, SG Ready, cascade and an energy meter.

Does it work with radiators?

Yes, with radiators sized for low temperature. Domusa states that flow temperatures of up to 60 °C allow it to be used with radiators.

Is commissioning included?

Yes. Domusa Teknik includes commissioning in its price; the technician's travel is charged separately.

What is the lead time?

It is in stock at our warehouse. Because of its weight, transport is quoted separately.

Can I install it myself?

No. It needs a licensed installation company and Domusa commissioning; Q-Tech integrates it and carries out the pre-commissioning check.

Q-Tech installation and support

Q-Tech delivers the Dual Clima R as part of a pre-assembled plant room: assembled, configured and tested in our workshop, with safety and operating tests. It arrives ready to connect, and the final connection is made by the site installer or by Q-Tech with the on-site Expert Technician by the day. See how it works in Pre-Montaje Avanzado and in the Expert Technician workshop pre-assembly service.

If another company installs the heat pump, or it is integrated into an existing system, Q-Tech first carries out a verification visit with the on-site hourly Expert Technician. We offer a remote or on-site pre-commissioning check so that the Domusa visit is not wasted on an unfinished detail.

This means fewer site visits and fewer on-site issues. For sizing questions, book a technical call or message us on WhatsApp. More units in heat pump systems and in our heat pump services.
