The BLN Series runs on R32 refrigerant, a cleaner, more efficient alternative to older refrigerants like R410a. R32 carries 32% lower Global Warming Potential and produces 70% fewer CO2 emissions over its lifetime. It also transfers heat more effectively, which means the system works harder with less electricity. For homeowners who want reliable heating and cooling without the environmental guilt, R32 is the smarter starting point.

The BLN Series carries the highest energy efficiency classification available — A+++. This is not a marketing label. It reflects a Seasonal COP above 4.5, meaning for every 1 unit of electricity the system consumes, it delivers more than 4.5 units of usable heating or cooling. Compared to a conventional electric heater or a standard split AC, the BLN Series can cut your annual energy costs by 60 to 70%. The savings add up quickly across a full heating and cooling season.

Most air source heat pumps struggle once outdoor temperatures fall below zero. The BLN Series does not. Using EVI (Enhanced Vapour Injection) technology and a full DC inverter Panasonic compressor, the system maintains stable heating output right down to -25°C ambient temperature. It also features an intelligent auto-defrost system that detects ice formation on the coil and clears it automatically. So performance stays consistent through the coldest months without any manual intervention.

The BLN Series is engineered for genuinely quiet operation. Full DC inverter technology allows the compressor to run at variable speeds — slowing down when demand is low rather than cycling on and off at full noise. Combined with precision-balanced ABS fan blades and 1Hz compressor control, the unit produces minimal vibration and low operational noise. Whether it sits outside a ground-floor window or on a terrace above a living space, it will not disrupt daily life.

The BLN Series draws heat from the outdoor air — heat that already exists and costs nothing to produce. The system simply moves it into your home rather than generating it from scratch using electricity. This fundamental difference is why a heat pump delivers so much more output per unit of electricity consumed than a conventional heater. You get the same warm home in winter and cool home in summer, at a fraction of the running cost.

The BLN Series comes with a built-in 5G/2.4G dual-band Wi-Fi module as standard. Connect it to your home network and control temperature, schedules, and energy monitoring from your phone — no additional hardware needed. The system also includes a photovoltaic linkage function. If your home has solar panels, you can programme the heat pump to prioritise operation during peak solar generation hours, effectively using free solar energy to heat or cool your home.
Gurugram, Haryana
"We installed the Hyundai BLN Series last October before the Delhi winter set in. The house stays warm without us doing anything — no scheduling, no manual adjustments. What genuinely surprised us was the electricity bill. It dropped by almost half compared to what we were spending on our old heating setup. Very happy with the decision."
Pune, Maharashtra
"I was sceptical about how quiet a heat pump could actually be — every product claims to be silent. But this one genuinely does not disturb anything. It sits right outside our bedroom wall and we never hear it. The temperature control through the app is a bonus I did not expect to use as much as I do."
Bengaluru, Karnataka
"We installed the BLN Series across six units in our gated community as a trial. The energy consumption data from the app made it easy to track performance. Fourteen months in and we have had zero maintenance calls. The auto-defrost and protection systems seem to handle everything on their own. We are now planning to extend the installation to the remaining units."
Chennai, Tamil Nadu
"Chennai summers are brutal and I needed something that could handle both heating in the mild winter months and cooling through summer without running two separate systems. The BLN Series does exactly that. One unit, one app, one electricity bill that is noticeably lower than before. Installation was smooth and the team explained everything clearly."
•An air-to-water heat pump extracts heat from outdoor air and transfers it to water in your building's hydronic system. In heating mode, it warms radiators or underfloor heating circuits. In cooling mode, it chills the water circuit to cool the space. It does not function as a split AC unit, but for homes with fan coil units or radiant floor systems, it can work as a boiler and chiller in a single outdoor unit.
•Capacity selection depends on the total heated area, insulation quality, and local climate. As a rough guide, a well-insulated 2BHK apartment (around 900 sq ft) in a moderate climate typically requires 6 to 8 kW. A 3 to 4 BHK villa in a colder northern Indian location may need 10 to 14 kW. For accurate sizing, we recommend a site assessment. So, you can contact the sales team with your floor plan and location for a free sizing recommendation.
•R32 has a lower environmental impact, with a GWP of 675, about one-third of R410a. It is mildly flammable, but safe due to small quantities and system design. It is not being phased out and is widely used. Future models may shift to R290 for even lower impact.
•Yes, the BLN Series supports solar panel integration through a PV linkage function. It can prioritise heating when excess solar energy is available during the day. This helps use free solar power efficiently and can significantly reduce electricity consumption, especially for hot water during sunny months.
•The BLN Series can operate in temperatures as low as -25°C using EVI technology. Even in such conditions, it can supply hot water up to 60°C. The system maintains a COP of around 2.0–2.5, making it suitable for cold regions and high-altitude installations.
•The BLN Series is a monoblock outdoor unit. It requires a separate indoor water tank or buffer tank. It connects through water pipes, not refrigerant lines, which makes installation simpler and removes the need for specialised indoor refrigerant handling.
•An A+++ rating means very high efficiency. The system typically delivers over 4.5 units of heat for every 1 unit of electricity used. Compared to electric heaters or gas boilers, this can reduce energy consumption by around 60–70% for the same heating output.
•The BLN Series includes a built-in 5G/2.4G dual-band Wi-Fi module as a standard feature. It does not require any extra purchase. Users can connect it to their home network and control the system remotely through the Hyundai smart app for scheduling and monitoring.
