JAG Alcaide is an official Vaillant installer in Barcelona. We install, commission and register the warranty for the ecoTEC Intro range — Vaillant’s entry-level condensing boiler, manufactured in Germany, available in 24 and 28 kW outputs.

The ecoTEC Intro is a wall-mounted combination boiler: it covers both central heating and domestic hot water in a single unit. It condenses combustion gases to recover heat that a conventional boiler expels to the outside, resulting in an ErP energy efficiency rating of 94% and an A energy label. The sensoROOM modulating thermostat is included as standard — it is not an optional extra.

As official Vaillant installers, the installation we carry out activates the full manufacturer’s warranty. We keep a record of every installation to handle any future warranty claims without the customer needing to track down paperwork.

Serie EcoTec Intro

Why the ecoTEC Intro for Barcelona

Barcelona flats have specific characteristics that determine which boiler to install. Most properties in the Eixample, Gràcia or Sant Gervasi are between 60 and 120 m² with one or two bathrooms — exactly the range the ecoTEC Intro 24/24 and 28/28 are designed for.

The 27 cm depth is a genuine practical advantage in flats with compact kitchens or tight utility cupboards. It is one of the most compact condensing boilers on the market — it replaces old room-sealed boilers occupying the same space or less. The horizontal flue kit and connection template are included in the unit price, eliminating unexpected costs on installation day.

The 1:7 modulation ratio means the boiler can operate anywhere between 3.5 kW and full output. In practice, a flat that only needs to maintain temperature on a mild spring day uses only the energy required — the boiler does not cycle on and off continuously, which reduces consumption and extends the working life of the unit.

What JAG Alcaide’s installation includes

Installation includes removing and disposing of the old boiler, fitting and installing the new ecoTEC Intro, connecting it to the gas supply, the heating circuit and the condensate drain, commissioning the system, configuring the sensoROOM thermostat and handing over all technical documentation to the customer.

As official Vaillant installers, we register the installation in Vaillant’s system to activate the full manufacturer’s warranty. We also issue the gas installation certificate required under current regulations (RITE), which is needed for any future dealings with the gas distribution company.

If the installation requires adapting the flue, modifying the existing heating circuit or adding bleed valves, we assess this at the free preliminary technical visit and include it in the fixed quote. No extra costs on installation day.

Frequently asked questions about Vaillant boilers in Barcelona

How much does it cost to install a Vaillant ecoTEC Intro boiler in Barcelona?

The total price depends on the model and installation complexity. The ecoTEC Intro 24/24 installed as a standard replacement (same location, compatible flue) typically falls in the range of €1,600–2,000 including VAT. The 28/28 in the same scenario is approximately €1,800–2,200. If the installation requires adapting the flue or modifying the heating circuit, this is detailed in the preliminary quote. The technical visit is free and the quote is fixed — no surprises on installation day.

Are you official Vaillant installers?

Yes. JAG Alcaide is an official Vaillant installer in Barcelona. This means that the installation we carry out activates the full manufacturer’s warranty, we have access to genuine Vaillant parts, and our technicians are trained directly by the brand. This is not the same as a general installer who works with any brand without specific accreditation.

What is the difference between the ecoTEC Intro 24/24 and the 28/28?

Both are combination condensing boilers (heating + domestic hot water) with the same dimensions, technology and efficiency rating. The difference is output: the 24/24 delivers 24 kW for heating and a hot water flow rate of ~13.8 l/min — sufficient for properties up to ~100 m² with one bathroom. The 28/28 delivers 28 kW and reaches ~16.1 l/min — suitable for properties up to ~130 m² or with two bathrooms. If you are unsure, we assess your property’s actual requirements at the preliminary visit and recommend the correct model.

What warranty does the Vaillant ecoTEC Intro carry?

The standard manufacturer’s warranty is 2 years. When installed by an official installer such as JAG Alcaide and registered in Vaillant’s system, the warranty extends to preferential conditions under Vaillant’s current extended warranty programme. We confirm the exact applicable coverage at the time of installation.

Is the sensoROOM thermostat included in the price?

Yes. The ecoTEC Intro is supplied with the Vaillant sensoROOM modulating thermostat included as standard — it is not a separate accessory. The sensoROOM has a built-in temperature sensor, allowing more precise regulation than conventional room thermostats. We install and configure it as part of the boiler installation.

How long does installation take?

A standard replacement (old boiler in the same location, compatible flue) is completed in one day — the property has heating and hot water working the same day. If the flue needs adapting or the heating circuit modifying, it may require an additional half day. We confirm the exact timing at the preliminary visit.

Do you carry out annual servicing and repairs?

Yes. We carry out the annual service recommended by Vaillant to maintain optimum performance and warranty validity. We also repair breakdowns on Vaillant equipment. See our maintenance contracts page →
