Vaillant recoVAIR VAR 60/2 D - set of 2 local heat recovery units (wired, with remote control)

Product detailed description

The set of local heat recovery units Vaillant recoVAIR VAR 60/2 D is a complete, ready-to-use solution for quiet, energy-efficient ventilation of two rooms at the same time. The package includes 2 pcs of the recoVAIR VAR 60/2 D ventilation unit (wired version), 2 pcs of installation kits (mounting tube for installation into the wall), 1 pc of white outdoor cover with noise silencer, and 1 pc of remote control for convenient operation of both units from a single location. This is the most popular way of purchasing this technology – instead of assembling individual components, you get a proven, manufacturer-recommended combination at a discounted set price.

Why choose a set instead of a single unit

Local heat recovery units recoVAIR VAR 60/2 work most efficiently and comfortably in pairs. The reason lies in the physical principle of their operation: each unit alternates the direction of airflow (intake / exhaust) every 70 seconds, and if only one unit were operating in a room, brief moments of slight negative pressure would occur during exhaust and slight positive pressure during intake. With a pair of units working in opposite phases – one intaking while the other exhausts, and vice versa – this effect is eliminated and air exchange in the room is smooth and balanced. This is exactly why Vaillant primarily offers this technology as a set of two units, and most installations in family houses and apartments are based on this configuration – for example, in a bedroom and a children's room, in a living room and kitchen, or even both in one larger room for higher air flow.

How local heat recovery with recoVAIR VAR 60/2 works

recoVAIR VAR 60/2 is a decentralized (local) heat recovery ventilation unit that solves ventilation directly where needed – in a specific room, bedroom, living room, office, or other space – without the need to build a central ductwork system throughout the house. The unit is installed into a single circular opening with a diameter of 162 mm drilled into the perimeter wall and connected to a 230 V electrical supply. No further construction work, no ductwork routed through ceilings or partitions, no ventilation plant room.

The heart of the unit is a regenerative ceramic heat storage exchanger. The fan in the unit operates in regular 70-second cycles, alternating the direction of airflow: in the first phase of the cycle, the unit exhausts humid, stale air from the room outside, while the heat from this outgoing air is temporarily stored in the ceramic structure of the exchanger. In the second phase, the fan direction reverses and the unit draws fresh outdoor air inside – as it passes through the still-warm ceramic exchanger, it picks up the stored heat, so the air entering the room is already pre-warmed. Thanks to this principle, the recoVAIR VAR 60/2 achieves a heat recovery rate of up to 92% (DIBt methodology), which significantly reduces heat losses caused by ventilation compared to conventional window airing.

To avoid pressure imbalance in a room or between neighbouring rooms, the units in a standard set are installed in pairs working in opposite phases – while one unit draws in fresh air, the other is exhausting stale air, and vice versa. This synchronization is controlled either by a cable connection (D variant) or wirelessly at a frequency of 868.0 – 868.6 MHz (DW variant). Up to 16 units can be interconnected in a single system (1 master "leader" and up to 15 "follower" units), so the solution can gradually be expanded to a larger apartment or family house.

An integrated humidity sensor can automatically switch the unit on when the humidity in the room exceeds a set threshold – typically after showering, cooking, or drying laundry – thus actively preventing water vapour condensation on cold surfaces and the formation of mould in room corners and behind furniture, which is an increasingly common issue in well-sealed modern homes as well as insulated older buildings.

Installation and mounting

Installation of the recoVAIR VAR 60/2 unit consists of a core drilling with a diameter of 162 mm through the perimeter wall, into which a mounting tube is fitted (an insulated plastic tube available in a length of 500 mm, which can be shortened, or, for thicker walls up to 1,000 mm, two tubes can be combined). On the exterior side, the opening is covered with a white outdoor cover with noise silencer type VAZ WD160, which also protects against rain and insects and reduces the transmission of outdoor noise into the interior. The unit itself is inserted into the prepared mounting tube from the interior side and connected to a 230 V/50 Hz electrical supply.

Units of the D variant communicate with each other and with any control panel via cable, which is the most reliable solution wherever it is possible, during renovation or new construction, to route a low-voltage cable between the individual installation points (e.g. in the partition wall between two rooms or in the ceiling void). The wired version is resistant to interference from other wireless devices in the household and does not require batteries in the communication module.

The unit's operating temperature ranges from −30 °C to +50 °C, so the recoVAIR VAR 60/2 reliably works even during freezing winters in Slovakia as well as during summer heat. The IPX4 protection rating ensures resistance to splashing water from the facade side. Installation can be completed by an experienced heating technician, electrician, or ventilation specialist within one day per room, without the need for a building permit (it is considered routine maintenance/modernization of the building envelope, though we recommend checking local regulations for heritage-protected facades).

Set package contents

• 2× recoVAIR VAR 60/2 D ventilation unit (wired version, code 0010047340)
• 2× installation kit – mounting tube for installation into perimeter masonry
• 1× VAZ WD160 outdoor cover with noise silencer, white, to protect the facade outlet
• 1× VAZ RC/2 remote control with display for convenient operation of both units

This combination represents a complete set required for installation in two rooms without the need to purchase additional basic components separately. If you are interested in more advanced control with a CO&sub2; sensor and automatic regulation based on air quality, we recommend considering the additional purchase of the VAZ CPC/2 wall control panel instead of, or in addition to, the supplied remote control.

Comparison with other ventilation methods

The local heat recovery unit recoVAIR VAR 60/2 thus occupies a middle position between simple but energy-inefficient ventilation methods (window, grilles, extractor fan) and costly, construction-intensive central ventilation systems – it offers most of the benefits of heat recovery (high efficiency, automatic regulation, humidity and CO&sub2; control) with minimal construction work limited to a single small opening in the wall per room.

Energy savings and return on investment

Ventilation by open window is the least efficient method of air exchange in terms of heat loss – during a short but intense airing (so-called burst ventilation), practically all the heat contained in the exchanged volume of air escapes outside, and the heating system must "repurchase" it by heating the cold air brought in from outside. With the recoVAIR VAR 60/2 type of ventilation, with a heat recovery rate of up to 92% (DIBt methodology), most of this energy is captured in the ceramic exchanger and transferred back to the supply air – heat that would otherwise escape through the window thus remains indoors.

The specific financial savings depend on several factors – the type and age of the building, the level of insulation, the price of heating energy, the number of ventilated rooms, and previous ventilation habits (how many times a day and for how long windows were opened for airing). In general, in more modern, well-insulated houses, where ventilation represents a relatively larger share of heat losses (since losses through the building envelope are already minimized by insulation), the benefit of controlled ventilation with heat recovery is most significant – not only financially, but also in terms of maintaining a stable, pleasant room temperature without draughts and without the temperature fluctuations typical of burst window ventilation.

The unit's low power consumption (1.7 – 10 W, specifically 0.44 W/(m³/h)) means that the fan's operation alone represents only a negligible item in the household's electricity consumption – roughly comparable to a small night light running continuously, significantly lower than with central ventilation units with long ductwork and larger fans.

Maintenance and filters

The recoVAIR VAR 60/2 unit uses a pair of filters – one of ISO Coarse 45% class on the supply (outdoor) air side and one of ISO Coarse 30% class on the exhaust (indoor) air side. Depending on operating conditions (urban environment, pollen season, proximity to a busy road), the filters should be checked and replaced approximately 2 to 4 times per year; the display on the control panel or remote control will indicate when replacement is needed. Filter replacement is a maintenance-free operation that does not require a service intervention – the filter cartridge is simply pulled out and replaced with a new one.

The ceramic heat storage exchanger is a maintenance-free component with no moving parts, which, under normal operation, does not require cleaning or replacement throughout the lifetime of the unit. We recommend having the fan checked once every few years during a regular service inspection of the heating/ventilation system, although it is a component designed for long-term maintenance-free operation.

Why choose this particular model

This set is the most economical way to solve insufficient ventilation in two rooms at once – typically where building a central ventilation system is not possible or economically viable, for example when renovating an apartment in a panel building, an extension, or when addressing mould and humidity issues in a bedroom and adjoining room. The wired D version is suitable whenever it is possible, during renovation or a new build, to route a communication cable between the two units – this is the most reliable and most cost-effective synchronization solution, without dependence on the quality of radio signal through masonry.
