NIBE launched its most powerful exhaust air heat pump yet, the manufacturer announced on 25 August 20231. The announcement appears on NIBE's own news page, where the item is listed under the headline "NIBE Launches Most Power Exhaust Air Heat Pump Yet" and dated 25/08/20231.
The company has not reported the model name, the heating capacity in kilowatts, the price, or the date the unit goes on sale. Those details are not given in the announcement listing1. The only product image associated with the item on the news page is a file named NIBE_S7351, but the listing does not state that the new unit is the S735, and no specification is published alongside it.
Exhaust air heat pumps recover heat from the air a home extracts for ventilation and use it to heat water and, in some designs, the building. NIBE's own news archive shows the category has been recognised at industry awards, with items headed "Exhaust Air wins again at the Energy Saving Awards!" dated 13/12/2024 and "A win for Exhaust Air Heat Pumps at the HVR Awards!" dated 01/10/20241. The archive also carries a 2025 item headed "Swedish tech, British homes, The Natural Way to Heat"1.
The launch sits among a run of NIBE announcements on the same page, including a strategic partnership with British Gas dated 18/03/2025, Quiet Mark certification dated 25/03/2025, and a direct-to-consumer channel unveiled at InstallerSHOW 2025 dated 09/07/20251. None of those items gives further detail on the exhaust air unit launched in August 20231.
"NIBE Launches Most Power Exhaust Air Heat Pump Yet"
Why it matters for households
Exhaust air heat pumps suit homes that are airtight and mechanically ventilated, where a single unit can cover ventilation, hot water and some space heating without an outdoor unit or a ground loop. For a household weighing up exhaust air heat pumps, the practical questions are capacity, how much of the heating load the unit covers, and whether the home's ventilation ducting and insulation are suitable. None of those figures is published in the announcement, so the claim of "most powerful yet" cannot be checked against a number from the company's own page1.
A more powerful unit in the range widens the set of homes a manufacturer can address, which matters where a household has been told its heat demand is too high for the smaller models in a range. Whether that applies here has not been reported1. Households comparing brands can look across NIBE heat pumps for UK homes and the wider heat pumps and manufacturers sections for context on how ranges are positioned.
What happens next
No availability date, price or technical specification for the new unit has been reported1. NIBE's news page lists later items, including a next-generation S2060 announced under the heading "Built for what's next" and dated 2026, and a UK campaign encouraging homeowners to rethink how they heat their homes, also dated 20261. Neither item states a connection to the August 2023 exhaust air launch1.
