If You Need a Spanish Roofer Tomorrow, Close Gemimarket.es

Close the tab if you need a Spanish mason this week

Do not buy from gemimarket.es if you need a licensed mason on a Spanish roof this week, a next-day carton from a depot in Madrid, or a technician who walks in with the box. The shop will take your euros. It will not climb the ladder. I opened the Spanish catalog on 27 September 2026 and the footer still named Gemi Elettronica Srl in Milan, not a chain warehouse on the M-40. If that sentence already bothers you, leave.

Walk away if you rent and cannot touch the cowl. Walk away if the flue is cracked, unswept, or shorter than a tall room and you were about to cheap out on a household galvanized fan. Stay out of the fence aisle if you want a solid pen for an animal that can hurt someone, or if your town’s rules on warning signs are still a shrug. A motor on the pot will not rebuild a collapsed liner. An energizer will not stand in for posts or a closed gate.

• You want a Spanish fitter to arrive with the parcel, or a next-day box from a depot inside Spain.
• You rent, and the landlord has not agreed to a new machine on the pot.
• The flue still wants a rebuild or a professional sweep before anything electrical goes on top.
• The stack is under three metres and you were aiming at the cheaper galvanized household fan.
• You live on salt air and hoped thin galvanized sheet would age like stainless.
• You need a hard pen for an animal that can injure someone, or the local rules on energizers and signs are still unclear.

Rewind. The Spanish shop is still an Italian factory till.

If you are still reading, you probably have a wood fire that pushes smoke back when the wind turns, or a small pasture that needs a pulsed wire. Gemimarket.es is the Spanish-language till of an Italian maker that has built roof fans and farm energizers since Domenico Giangreco put the GEMI name on the work in 1983. The contracting company is Gemi Elettronica Srl, VAT IT01765660764, at Viale Monza 347, 20126 Milan, with the plant at Contrada Piano Mulino, Lotto A1, 85034 Francavilla sul Sinni in Potenza. Milan answers on (+39) 02 87165556. Francavilla answers on (+39) 0973 577845. The Spanish-shop inbox is customergemi@gmail.com. Pay in euros. Expect a carton that started in Italy.

On that September pass the homepage still showed the two aisles — roof extractors and electric fences — and still printed both Italian addresses. The exact euro stickers I wanted to lift from individual tiles that morning were unpublished on the pages I could read, so I am not inventing a till total. Earlier September snapshots sat around three hundred euros for a galvanized household fan and a little over four hundred for the professional painted extractor. Treat those as a ballpark. Confirm the live cart. About pages mention Basilicata Innovazione. Treat that as history, not a permit to skip a sweep.

Who should actually stay in the cart

This till makes sense for a household, a holiday house, or a small kitchen with a wood fireplace, a pellet stove, a masonry barbecue, or a passive hood that blows smoke back into the room. You can get on the roof with a tape. You can photograph the old cowl. You can follow a video. Call an electrician yourself if the wiring looks messy. The second kind of buyer is a small farm or garden that runs a pastor eléctrico for sheep, goats, or a crop line that wild boar keep testing. Same checkout. Same Italy-origin parcel. Different tape measure: fence length and earth, not a pot diameter.

You also need patience with a factory clock. Spanish buyers should assume the European Union timing unless checkout prints something tighter. I did not see a walk-in counter in Madrid or Barcelona. If you want a VAT invoice, match P.IVA IT01765660764. If you want someone to dry-fit the unit against the pot while you hold the ladder, you are on the wrong site. Ordering the fan before you measure the pot is putting the cart before the horse. The carton can be perfect. The masonry can still refuse it.

The pot on the roof is the only measurement that matters

The extractor pages talk about the chimney you already own, not a dream flue. For round pots, write the outside diameter. Ignore the inner liner. The size run I have seen goes from twelve centimetres to forty. Square and rectangular stacks share one adjustable family, twenty by twenty up to forty-three by forty-three. Wider than that, the copy says four Fischer-type screws will hold the lower support. Stand on the roof. Measure the outside of the pot. Photograph the old hat. A round fan on a square masonry cap is a wasted carton.

The factory envelope is dull and useful. Base: forty-three by forty-three centimetres. Height: thirty-five centimetres without supports, fifty with them. Several listings sit around eighteen kilograms, so plan two people on the ladder. The height split is blunt. Galvanized household units are for chimneys taller than three metres. The professional family, rated to seven hundred degrees Celsius, can go on ducts as short as one metre. If a metal liner sticks up from square masonry, cut it flush and stuff mineral wool into the gap before you pick a square rotating base. A fan will not draft a blocked, unswept flue. I think people underestimate that two-person lift until the box is already on the landing.

• Write the outer diameter, or the outer width and depth, at roof level. Ignore the firebox.
• Note the height from fire to pot. Under three metres points to the seven-hundred-degree professional family.
• Photograph the cowl. The factory sells a hat version and a no-hat version for in-flue mounting.
• Check ladder space for an eighteen-kilogram lift that needs two people.
• Decide the cable path now: ordinary 3 x 1.5 mm lead outside the stack, or the maker’s high-temperature silicone lead if the cable has to travel inside the flue.

Two products. Then I stop naming things.

I am only going to name two things, because the rest of the homepage is metal, warranty years, and kits that change with the week. The professional painted extractor is the usual step up when the stack is short or the fire runs hot. That family is rated around three thousand eight hundred cubic metres an hour and seven hundred degrees Celsius, with six years of cover. Stainless, Corten, and copper keep the same airflow and heat numbers. You pay for the skin and the extra years. The forty-three-by-forty-three base does not change. The way the unit ages does. None of those finishes pull smoke through a blocked liner. Earlier September carts put the painted unit a little over four hundred euros.

The cheaper galvanized household line is the one people reach for first, and it is the wrong reach on a short restaurant-style duct. That line is quoted around two thousand five hundred cubic metres an hour and three hundred degrees Celsius, with three years on the electrical and structural parts. Use it on a household wood fire with a tall stack. Open the current Spanish datasheet instead of treating a marketing bullet as a building permit. Coastal salt is why the premium skins exist: eight years on stainless and Corten, ten on copper. An optional extra-year pack has sat around thirty euros. I am not turning that into a third named product.

The second named product is the E/220 mains energizer. Earlier September snapshots put it around one hundred and fifteen euros, against a higher struck-through figure I will not treat as a promise. The page talks about 220 volts, fifty hertz, up to ten thousand volts, a maximum of five joules, and a claimed five kilometres of conductor when the fence is clean. Weeds, thin wire, and dry earth all cut that figure. A ready kit usually adds wire, insulators, earth stakes, an output lead, and warning signs. Ready kits have run from about one hundred and twenty-five euros to solar packs above three hundred and forty. Posts are not always in the carton. This is farm gear.

After the fire catches, leave the knob on 1 or 2

The box on the wall is a six-speed autotransformer. Once the fire has caught, leave it on 1 or 2 so the fan pulls smoke and does not drag the heat straight out of the room. The top notch is for airing the space, for a stubborn first light, or for ash. Gemi warns that full speed can make the fire run hotter and throw more warmth up the pot. Their “does not extract heat” line is a low-speed claim, not a physics trick. Keep the regulator off the hearth. If the power dies, the blades stop and the flue itself stays open. That is what the factory writes. A short, cold, or damaged stack can still misbehave.

They sell the fit as something you do from a video. Take the old hat off, sit the unit on the pot, clamp or screw it down, then take a cable to the indoor box. Outside the stack you extend with ordinary 3 x 1.5 mm lead from the metre already on the fan. Inside the flue you want the maker’s silicone lead in a steel sheath, rated above 350 degrees Celsius. That option has started around thirty euros for five- to thirty-metre reels. Keep any inner run about a metre clear of the flame. If you freeze, they tell you to ring an electrician or a mason. Nobody from Milan is coming to a Spanish slate roof.

Measure the pot you already have, pick the seven-hundred-degree family if the stack is short, and leave the controller on 1 or 2 after the fire catches. The fan does not replace a sweep.

How a click becomes a carton from Italy

The till takes cash on delivery, a bank transfer, PayPal, and cards. Some product pages also show Klarna in three parts, and that split depends on the basket and a credit check. The same Italian Srl’s terms say the contract exists once the order reaches their server, and the goods leave after payment unless you chose cash on delivery. VAT is already inside the euro figure. Ask for a paper invoice while the form is still open, not after the courier has a label.

The shipping page splits four bands. I am not reprinting them as a grid here; the list below is the same copy in words. Because the seller and the plant sit in Italy, a Spanish address should assume the Union window unless the till prints something tighter. And that is before you even open the fence catalog, where a sold-out remote-paddock bundle can wreck a Monday plan.

Freight in words, because a table would lie

I am putting the money bands in words on purpose. A grid of codes would make an eighteen-kilogram roof fan look like a bookshop parcel. These are the published splits I could still read from the shop’s own shipping copy, checked against what the site still showed on 27 September 2026. They are not a model price. If a zone or a surcharge was blank that morning, it stays unpublished.

• First band, no country heading: about ten euros under ninety-nine euros, free above, one to three business days.
• European Union and United Kingdom: free above ninety-nine euros, about ten euros below that line, three to five business days.
• Extra-EU Europe, North America, Russia, and Switzerland: five to seven business days, freight shown only at checkout.
• South America, Asia, Africa, Oceania, Central America, the Antilles, and Cyprus: six to eight business days, also calculated at checkout.
• Paying the bill: cash on delivery, bank transfer, PayPal, cards, and Klarna in three parts if the credit check passes.
• Coming back: free collection inside 100 days at the seller’s cost; you still get an eighteen-kilogram, soot-stained machine off the pot.

A 100-day return still needs two people and a ladder

The shop’s own extra is a free 100-day return, collected at their cost, with no reason required. That sits on top of the usual EU withdrawal window. You still have to get the machine off the pot and give it to the courier they name. Other Gemi sites ask for the original carton when the serial number is on the box. Photograph what you fitted, keep the invoice, and open the request by email or phone. If the cable is already cut or you drilled the masonry, say that before you assume the money comes back in full. I did not see a restocking charge printed on gemimarket.es, so ask in writing.

Warranties track the metal, not your mood. Three years on the galvanized household line. Six on the painted professional extractor. Eight on stainless and Corten. Ten on copper. Time runs from the order date if you add the extra-year pack. A stopped fan does not seal the flue. Keep a working carbon-monoxide alarm and dry wood. Call, chat, or email if the cable run confuses you. They will not send a fitter from Francavilla to a Spanish holiday house in February.

FAQ

Is gemimarket.es a Spanish company?

No. You are buying from Gemi Elettronica Srl, which sits in Milan and Francavilla sul Sinni. The phones are Italian. The Spanish inbox is customergemi@gmail.com. You pay in euros and the box starts in Italy. Put P.IVA IT01765660764 on the invoice if you need the VAT number. I did not find a public counter in Madrid or Barcelona on 27 September 2026.

Can I put the extractor on without a mason?

They tell you to watch the video, park the eighteen-kilogram unit on the pot, fix it with the clamps or screws, then wire the six-speed box. Plenty of houses will still want a mason on the tiles and someone to wire the indoor regulator, especially on slate. You can swap the old hat, or buy a no-hat version and drop it inside the chimney if the size works. They will answer cable questions. They will not send a crew.

What arrives in a fence kit, and what does not?

The carton is an energizer plus the first-day bits: a stated length and section of wire, insulators for a named post type, earth-stake hardware, the output lead, and warning signs. Posts themselves are often missing. Mains packs assume 230 volts at the barn. Battery and solar packs assume a 12-volt supply. The five-kilometre figure on the E/220 page is a clean-fence maximum. Take the kit if you want matched parts. Take the energizer alone only if the wire and insulators you already own will fit.

If the power cuts, does the room fill with smoke?

The factory FAQ says a dead fan does not close the pot, so ordinary draft can still run, even in wind. That is not a guarantee for a cold, short, or damaged chimney. Keep the alarms working, sweep the flue, and be ready to kill the fire if smoke comes back. I did not see a battery backup listed as a standard extra on the extractor pages I opened on 27 September 2026. If one exists later, it was unpublished that morning.

How do I pay, and when does the order lock?

Cash on delivery, bank transfer, PayPal, and cards sit on the checkout page. Klarna’s three parts depend on a credit check, so do not build a roof date around an approval you have not seen. The same Srl’s terms say the deal exists once the order reaches their server. Goods leave after payment unless you chose cash on delivery. VAT is already in the price.

How do 100-day returns work once the fan is on the roof?

They will collect within 100 days at their cost and they do not ask why. You still have to get an eighteen-kilogram, soot-stained machine off the pot and give it to the courier they name. Photograph what you fitted. Write or call to start it. If you already cut cable or drilled the masonry, say that before you assume the money comes back in full. I did not see a restocking fee in writing, so ask.

Will they deliver to a Spanish holiday house in winter?

A Spanish address should land in the Union band unless checkout prints a tighter or looser window. That is three to five business days in the published copy, free above ninety-nine euros. A holiday house with no one home is your problem, not Francavilla’s. Put a neighbour on the label if the place is shut. Ask in writing if the road is seasonal. The factory will not store the box in a Spanish depot until March.
