Why Choose the Hitachi airHome 800?
Flagship comfort, intelligent airflow and sophisticated air treatment. FrostWash, Mold Guard, AQtiv-Ion, Wi-Fi and finish options are model dependent, so we confirm exactly what is included on the capacity you choose.
Flagship Energy Efficiency
Advanced inverter heat pump technology provides highly efficient heating and cooling throughout the year. Verified seasonal energy efficiency ratings are confirmed for each capacity rather than quoted for the range as a whole.
Whisper-Quiet Operation
Designed for exceptionally quiet indoor operation, making the airHome 800 suitable for bedrooms, living rooms and home offices. Verified minimum indoor sound pressure levels are given for the exact model and fan setting you choose.
FrostWash Technology
Where supported, the heat exchanger undergoes a controlled freezing and defrosting cycle that helps remove accumulated dirt. FrostWash does not replace regular filter cleaning or professional servicing.
Mold Guard Technology
Where supported, Mold Guard helps dry internal components after operation to reduce the conditions that encourage mould growth. It does not prevent mould completely.
AQtiv-Ion Air Treatment
Where supported, Hitachi's AQtiv-Ion air treatment technology is explained using verified manufacturer documentation of what it does. We make no unsupported claims about guaranteed removal of viruses, bacteria or allergens.
Advanced Air Filtration
The filtration and air treatment features confirmed for the exact model are described using Hitachi's own terminology, with any differences between capacities set out rather than generalised.
Intelligent Airflow Control
Airflow technology designed to distribute heated and cooled air comfortably around the room, with automatic swing, adjustable airflow direction and intelligent distribution where the model supports them, helping to reduce direct draughts.
Smart Wi-Fi Control
Where supported, the airHome 800 can be controlled through Hitachi's compatible smart air conditioning app, such as airCloud Go, for temperature adjustment, mode selection, scheduling, energy monitoring and voice assistant control where available. Wi-Fi is not standard across every model — we'll confirm whether it is built in, requires an optional accessory, or is unavailable.
Powerful Summer Cooling
Responsive cooling technology helps maintain comfortable indoor temperatures during warmer weather.
Efficient Winter Heating
Advanced heat pump technology provides efficient heating during colder months.
Comfortable Sleep Mode
On supported models, Sleep Mode adjusts operation to help maintain comfortable conditions overnight.
Dehumidification
Dry Mode helps reduce excess indoor moisture during appropriate operating conditions.
Premium Modern Design
Refined styling and a contemporary appearance. We show the colour and finish options confirmed as available for the exact UK model you choose.
R32 Refrigerant
Uses R32 refrigerant where confirmed for the selected model, offering a lower global warming potential than older R410A systems.
We only advertise features confirmed for the exact UK model and capacity you choose, so nothing here is presented as standard unless it is.

Seasonal heating efficiency
The Hitachi airHome 800 uses advanced inverter heat pump technology to provide efficient heating and cooling. By transferring heat rather than generating it directly, the system can deliver multiple units of heating energy for each unit of electricity consumed under suitable conditions.
Because heat pump heating moves existing heat rather than converting electricity directly into heat, it can use less electricity than conventional direct electric heating to deliver the same amount of warmth, which may reduce running costs. Actual savings depend on your property, tariffs, outside temperatures and how the system is used, so we don't quote fixed figures.
Exact SEER, SCOP and energy ratings differ between capacities, and which UK model sits behind each capacity is confirmed when we quote. We'll give you the published figures for the model and capacity you choose rather than applying one model's ratings across the whole range.
Available System Sizes
We fit the Hitachi airHome 800 in the capacities below. Prices are the installed price for one room on a standard back-to-back installation.
| Nominal cooling capacity | Typical application | Installed from |
|---|---|---|
| 2.5 kW | Bedrooms and smaller living rooms | £2,149 |
| 3.5 kW | Medium-sized living rooms | £2,249 |
| 5.0 kW | Larger lounges and open-plan spaces | £2,449 |
| 7.1 kW | Large residential spaces | £2,649 |
These are the capacities held in our system and confirmed for the UK airHome 800 range. If you need a size that isn't listed, ask us and we'll confirm availability and price the exact model rather than estimating it.
Multi-split systems are quoted only where the exact indoor and outdoor models are confirmed compatible by Hitachi, so a multi-room price is never assumed.
Correct system sizing depends on room dimensions, insulation, glazing, ceiling height and heat load. Frost Air Conditioning can advise on the most suitable system.

Regular filter cleaning, professional servicing and appropriate ventilation all remain important, and air treatment functions do not replace any of them.
