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 Vitorondens 200-T?

The Viessmann Vitorondens 200-T is an oil boiler that combines a cast iron body with a stainless steel condensing heat exchanger. The heat exchanger recovers the heat of the flue gases that a non-condensing boiler loses up the chimney. It stands on the floor of the boiler room or garage.

Vitorondens 200-T technology

  • Vitoflame 300 blue-flame oil burner, models VHG I-2 to VHG II-2 depending on output.
  • Eutectoplex cast iron heating surfaces and JetFlow system, which distributes the heating water to prevent condensate and stress cracks in the cast iron.
  • Stainless steel Inox-Radial heat exchanger, corrosion-resistant and with a self-cleaning effect.
  • Horizontal flue passages that make cleaning the combustion chamber easier.
  • Vitotronic control unit with display; supplied pre-wired.

What problem does it solve?

Many homes without mains gas still run an old non-condensing oil boiler that sends the heat of the flue gases up the chimney. The Vitorondens 200-T keeps the oil supply and the tank, and recovers that heat.

The usual mistake is to order the same output as the old boiler, or the wrong version for the boiler room. Before buying, check the heat losses of the house, whether the room has enough ventilation and where the flue can run.

Frequently asked questions

Which version do I need?

It depends on the installation. With a single circuit without mixing valve, the Vitotronic 100 KC4B is enough; if you need circuits with mixing valve or weather-compensated control, the Vitotronic 200 KO2B. The type of operation depends on the room and the flue.

What is the difference between open-flued, coaxial and parallel?

Open-flued, the boiler takes combustion air from the room. Room-sealed, it takes air from outside: with coaxial, flue gases and air share one concentric duct; with parallel, they use two separate ducts.

Does it run on oil with biocomponents?

Yes. According to Viessmann, it accepts heating oil with up to 10 % biocomponents (Bio 10).

Can it be controlled from a phone?

Only with the Vitotronic 200 KO2B and the Vitoconnect OPTO2. According to viessmann.es, ViCare control is available up to 35 kW.

Which accessory is mandatory?

The small distributor with safety group: 7248938 up to 42.8 kW and ZK02643 for the 53.7 kW model.

What is the delivery time?

We have it in stock in our warehouse. Because of its weight, shipping is quoted separately.

Can I install it myself?

No. An oil boiler must be installed and registered by a licensed installation company; Q-Tech coordinates it with a partner installer, quoted separately.

Q-Tech installation and support

In our workshop, Q-Tech places the Vitorondens 200-T in a pre-assembled plant room with its distributor, control unit and hydraulics. We connect, fill and test it there: the plant room leaves tested and ready to connect. On site it is connected by your installer or by our On-site Expert Technician per day. We explain it in Pre-Montaje Avanzado and in the workshop pre-assembly service.

Replacing an existing oil boiler? First book a visit from the On-site Expert Technician by the hour to check the room, the flue and the tank. For questions, book a technical call or message us on WhatsApp. The full range is in Viessmann oil boilers and components.
