Heat Pumps in Ataşehir: Vaillant Installations for Gated Complexes, Residences and Detached Homes

The short answer: heat pump sales, installation and commissioning in Ataşehir are carried out by EFE YAPI VAİLLANT. We are an authorised Vaillant dealer, and our showroom is in Ümraniye, the district next to Ataşehir, at Çamlık Mah. İkbal Cad. Uğurlu Sk. No:35/A. That closeness makes the most tedious part of the job easier: the survey. The right decision on a heat pump does not come from a floor area described over the phone; it comes from seeing where the outdoor unit will stand, how the pipes will run and what the electrical panel looks like. Because we can reach Ataşehir quickly, we survey early rather than putting it off, and come back a second time for measurements where that is needed. Our professional installation service covers Türkiye nationwide; product supply also goes across Türkiye, and you will find our scope on the Istanbul and across Türkiye pages.

In Ataşehir the real variable shaping a project is the building type. In detached houses and villas with gardens the outdoor unit is usually easy to place: a point with unobstructed airflow, service access and somewhere for the condensate to drain is enough. In multi-block complexes, residences and blocks of flats, the same unit requires three separate issues to be solved at once. The first is physical space: a balcony, a terrace or an area under your own use. The second is the neighbour relationship: which way the unit discharges, which surfaces the noise reflects off, and the anti-vibration arrangement that keeps vibration out of the structure. The third is the condensate; a drain that drips onto the floor below is technically minor but, in neighbourly terms, the biggest problem of all. We go through these three points one by one at the survey, because solving them afterwards is both expensive and unpleasant.

In complexes and residences the second step is permission. Whenever the outdoor unit affects the façade, a communal area or someone else's space, approval from the site management or the owners' association is required. This is not a formality but a genuine milestone in the project, and we strongly advise against ordering equipment before that approval is in. What we can do is make the process easier: after the survey we share the possible placement alternatives, the unit dimensions and the installation detail in a tidy form you can put to the management. Some complexes already have a defined arrangement for air conditioning outdoor units, and a heat pump outdoor unit can be positioned on the same logic; you need to find that out from your own complex's rules, as we do not make general assumptions. We have gathered the technical checklist on the installation side in our article on heat pump installation requirements.

The third deciding factor is the home's heating system, and in Ataşehir we see a clear split here. In newer buildings with underfloor heating a heat pump is already at its natural operating point: underfloor heating runs at a low flow temperature, and the heat pump produces the same heat for less electricity as the water temperature drops. In those homes the discussion is not about high temperature capability but about the right kW and the outdoor unit placement. In homes with radiators, the system is expected to produce higher water temperatures. Here aroTHERM pro stands out: with natural R290 refrigerant, an A+++ energy rating and flow temperatures up to 70 °C, it makes the switch possible without stripping out the radiator system, and it comes in four capacities. Where higher temperatures are needed, aroTHERM plus reaches 75 °C and is listed in 8, 12 and 15 kW capacities. You can find the detail on the R290 side in our aroTHERM pro review.

In Ataşehir the monobloc-versus-split decision largely follows from placement. On a monobloc, the entire refrigerant circuit is sealed inside the outdoor unit; it takes up almost no indoor space and needs no refrigerant work on site, which is why it is the preferred choice in detached houses with gardens. On a split, the water circuit stays in the indoor unit and only refrigerant lines run outside, which is an advantage when a more compact layout is wanted on the outdoor side. At flat scale, aroTHERM Split plus covers small and medium heat losses at 4, 6 and 8 kW, while aroTHERM pure Split, with R32 refrigerant in 6, 8 and 10 kW capacities and versions carrying a 190-litre cylinder, suits those who want heating and hot water in a single package. For larger volumes, aroTHERM Split intro comes into play with 8, 10, 12 and 16 kW capacities and backup electric heater options. And on villas whose garden allows a borehole or a horizontal collector, the flexoTHERM / flexoCOMPACT exclusive family can run on ground, water or air in 5, 8, 11, 15 and 19 kW capacities. You can see the full list on the heat pump products page.

Two infrastructure points should be checked early. The first is electrical: a three-phase supply comes into play as the capacity grows and a backup electric heater is brought in, so at the survey we look at your existing connection, your flat's consumer unit and the fuse arrangement. In complexes and residences, learning the limits of the consumer unit early is far cheaper than redesigning the project later. The second is domestic hot water: alongside the heat pump, the uniSTOR RW cylinder family can be used in the 200–500 litre range, while for smaller requirements the pure Split versions with a 190-litre cylinder do the job. The myVAILLANT Smart and sensoCOMFORT controls are used to manage the system, and we set the heating curve and the hot water programme together at commissioning. Since we also carry out combi boiler installation and air conditioning installation under the same roof, we can also discuss set-ups that work alongside your existing boiler.

Our position on price is straightforward: there are no figures on this page. The cost of a heat pump project depends on capacity, on the monobloc or split decision, on the cylinder volume, on the control unit and on the scope of the installation; that is why we give pricing only as an individual quote over WhatsApp. Nor do we promise a payback period in years. The logic of the calculation is simple: you divide the investment cost by the annual difference between what heating with your current fuel costs you and what the heat pump consumes in electricity. Because your own bills, your own tariff and your home's real heat loss set that difference, a sound answer only comes from a calculation done for you; we set out the method step by step in our article on heat pump costs and savings, and if you want to compare against a combi boiler, heat pump vs combi boiler is a good start. In short, in Ataşehir this job begins not with choosing the right unit but with settling the right placement and the permission it needs; the capacity calculation, the flow temperature and the cylinder choice come after that. A reminder once again that we do not offer standalone maintenance, servicing or repairs.
