Vaillant Boilers, ACs & Heat PumpsWith Professional Installation

As an authorized Vaillant dealer, EFE YAPI VAİLLANT pairs combi boiler sales with professional installation on both sides of Istanbul. Condensing boilers recover heat from the flue gases and use noticeably less gas than conventional units — a difference you'll see on your bill across Istanbul's long heating season. Our range runs from the ecoTEC intro, built in Turkey, through the ecoTEC pure and plus series to ecoFIT models, electric boilers and combis with built-in hot water storage. The right model depends on your apartment's size, the number of radiators and your hot water needs. Not sure? The boiler selection wizard points you to the right options in a few questions, and you can also view models side by side with the comparison tool.

Replacing a boiler is about more than mounting a unit on the wall: İGDAŞ project approval and gas activation are a major part of the job. With our boiler installation service, we follow that process through from start to finish — no chasing project paperwork or gas appointments yourself. We also take your old boiler in exchange for a discount; removal, installation of the new unit and commissioning all happen on a single plan, keeping the time your home spends without heating and hot water to a minimum.

In Istanbul's hot, humid summers, choosing the right air conditioner starts with sizing the capacity (BTU) to the room: its dimensions, ceiling height, insulation and sun exposure are weighed together. An undersized unit struggles to cool the room; an oversized one keeps stopping and starting and wastes electricity. Vaillant's Pure, Pro and Multi series cover different room sizes as well as setups where a single outdoor unit serves several rooms. Browse all the models in our product catalog.

With air conditioning, installation quality matters as much as efficiency: correctly positioning the indoor and outdoor units, running the copper piping with care and vacuuming the lines all directly affect the unit's performance and lifespan. Our air conditioner installation service combines the sale and the installation in one, across Türkiye — including guidance on placing the outdoor unit within your building management's rules.

Heat pumps — electric systems that move heat from the outdoor air into your home — stand out as an efficient alternative that can both heat and cool. Because they can deliver several times more heat than the electricity they use, they lower running costs, particularly in well-insulated homes. The Vaillant aroTHERM Plus monobloc offers a straightforward single-outdoor-unit installation, while the aroTHERM Split adapts to different layouts. See our heat pump page to gauge whether your home is a fit, then talk to us.

We also carry the products that complete your heating system: wired and wireless room thermostats stop the boiler running when it isn't needed, preventing wasted fuel. Panel radiators improve heat distribution, and electric and gas water heaters plus boiler flue accessories round out the range. For tips on efficient use and saving energy, browse our blog.
