Gas Wall Heaters in Barcelona

The advantages of the wall mounted gas heaters are that they are very easy to install compared to the normal water heating systems and, if you want to increase the number of radiators in the future, you won’t find any problems with doing so.

Thanks to their working system, each of the installed radiators can be controlled independently, this way you’ll be able to keep working only the ones you’re going to use, while the ones you’re not using will stay turned off, meaning you won’t be spending any energy you don’t require.

Some of the many advantages of wall mounted gas heaters are their integrated thermostatic control, low power consumption and easy installation.

As you will be able to read in the two pages where we explain the different brands of wall mounted gas heaters that we work with, there are different models with different characteristics. Among these models, you can find the ones that have no electronic ignition nor forced draft fan, so they require no electricity power. When it comes to these models you’ll only need a gas pipe and a flue kit in order to get the fumes out. On the other side there’s the radiators that have a fan incorporated in order to help expulse the fumes out, and they have also electronic ignition. These ones do require electrical installation.

Do you have a Strachenova installed?

Strachenova was for decades the reference brand for gas wall heaters in Spain. Many Barcelona flats still have one in operation — or one that has stopped working and needs replacing. Kromschroeder acquired the Strachenova technology and product line and is today its direct successor. The Echo XC and Echo XN models are the natural evolution of the Strachenova: the same philosophy of autonomous wall-mounted heating, updated to meet current gas and energy efficiency regulations.

If your Strachenova has been installed for many years, spare parts are no longer available, or it has simply stopped working, at JAG Alcaide we assess the replacement, explain which Kromschroeder model best suits your space and manage the full installation including adapting the flue outlet — which in most cases requires a new hole in the wall as the dimensions no longer match older models.

What should you consider before installing a gas wall heater?

Three things determine the installation: the gas supply (there must be an accessible gas valve near the installation point), the flue outlet (all current models are sealed flue and require an external outlet, which in most replacements means making a new hole in the wall), and an electrical supply if the XN model is chosen. JAG Alcaide assesses all of these at the free preliminary visit and provides a fixed all-inclusive quote.

Frequently asked questions about gas wall heaters in Barcelona

How much does it cost to install a gas wall heater in Barcelona?

The price depends on the chosen model and installation complexity. The unit cost ranges from €600 to €1,200 depending on output and series. Installation is quoted separately and includes the gas connection, flue outlet and, where applicable, the electrical connection. For most standard installations, the total (unit + installation + VAT) is between €900 and €1,600. We provide an exact quote at the free preliminary visit.

Is a sealed flue unit now mandatory?

Yes, following the update to the Regulation on Thermal Installations in Buildings (RITE). New models cannot draw combustion air from inside the property — they must have a direct external outlet via a coaxial pipe. This is why almost all installations now require a new hole in the exterior wall.

Can I replace my Strachenova with a Kromschroeder?

Yes, it is the recommended direct replacement. Kromschroeder is the successor to Strachenova and the Echo models are its natural evolution. The only consideration is that the flue outlet will likely not align with the old unit’s opening, so the hole will need to be adapted or a new one made. We assess this at no cost during the visit.

What is the difference between the Echo XC and Echo XN?

The Echo XC has no fan and requires no electrical supply — it heats by natural convection. The Echo XN has a tangential fan that distributes heat more evenly around the space and allows hourly and weekly programming, but requires an electrical connection. For spaces without a nearby power socket, the XC is the solution.

Does a gas wall heater also provide hot water?

No. A gas wall heater is exclusively for space heating. It does not produce domestic hot water. If you also need hot water, the solution is a separate water heater or, if you want to combine heating and DHW, a mural boiler.

Do you carry out servicing and inspections?

Yes. We carry out the mandatory annual gas appliance inspection for Kromschroeder, Fondital and Strachenova wall heaters. The annual inspection is required by regulation and necessary to maintain the unit’s warranty and home insurance coverage.
