Daikin Ururu Sarara: five climate functions in one wall unit

The Ururu Sarara is a wall-mounted R32 split, model code FTXZ-N, and Daikin's most fully featured home unit. Unlike the rest of the range it is single-split only, one indoor unit on one outdoor unit, because of the extra humidification and ventilation hardware built into the indoor cabinet.

It combines five functions: heating, cooling, humidification, dehumidification and fresh-air ventilation, along with air purification. It humidifies without a water tank by drawing moisture from the outside air, and it renews a room's air rather than just recirculating it. It is the most efficient Daikin home unit, rated A+++ across its 2.5, 3.5 and 5.0 kW sizes, and runs from 19 dB(A). The trade-off is bulk: the indoor unit is 372 mm deep, far deeper than a slim Stylish.

The Ururu Sarara does five jobs in one unit. It heats and cools like any reverse-cycle split. It humidifies (the Ururu function) by pulling moisture from the outdoor air, so there is no tank to refill and none of the bacteria risk of a standalone humidifier. It dehumidifies (the Sarara function) to take the edge off muggy days. And it ventilates, drawing in fresh outside air rather than just recirculating what is already in the room, with air purification running throughout.

It is worth being clear about what it is not. It is still an air-to-air air conditioner, not an air-to-water heat pump. A £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps applies in England and Wales from 28 April 2026, but only if the unit replaces a fossil-fuel heating system and is fitted by an MCS-certified installer, so comfort cooling added alongside a retained gas boiler does not qualify. Its ventilation is also single-room fresh-air intake, not a ducted whole-house heat-recovery (MVHR) system. And the extra hardware makes the indoor unit deep, 372 mm, so it juts out further than a slim Stylish. Buy it for genuine humidity and fresh-air needs in a bedroom, nursery or study; if you only want heating and cooling, a Perfera or Stylish is better value.

The Ururu Sarara is the most expensive unit in the Daikin home range. Supply-only, the indoor and outdoor pair runs from roughly £1,580 to £2,060 excluding VAT across the 2.5 to 5.0 kW sizes from a UK trade retailer. Supplied and fitted, budget from around £3,000 and up, materially above an equivalent Emura or Stylish, which sit around £2,100 to £2,900 fitted. It is a lower-volume, specialist product, so stock and lead times can be less predictable, and prices vary widely. Get two or three fitted quotes. These figures are correct as of July 2026.

As the most efficient Daikin home unit, rated A+++ throughout with SCOP up to around 5.9 on the 2.5 kW, in heating it returns close to 6 kW of heat for every 1 kW of electricity on the smallest size. In cooling, its per-hour running cost is comparable to the other Daikin splits, though the humidification and ventilation functions add some consumption when they are active. Any figure assumes an electricity rate of 27p per kWh, correct as of July 2026; the Ofgem price cap changes quarterly, so check the current rate.
