Heating-Capable 4-in-1 Units
These Sealey portable air conditioners feature a built-in heat-pump heating mode — the same unit that cools your workshop in summer now warms it through autumn and winter. Plug in, set the temperature, and enjoy efficient directional heat without firing up the whole building's central heating.
Multi-Brand Heat-Pump AC Range
Beyond the Sealey portables above, we supply heating-capable (reverse-cycle) air conditioning from 13 leading brands — from whisper-quiet wall-mounted inverter splits (COP up to 4.1) to industrial 29,500 BTU portable heat pumps and 4-way ceiling cassettes for open-plan floors. Every unit in this range heats as well as cools, giving you year-round climate control from a single capital purchase.
🔌 Portable
Plug-and-play units on castors — wheel in, plug into a 13A socket and heat instantly. No installer, no flue, no disruption.
🧱 Wall-Mounted Split
Fixed high-wall inverter systems for permanent, whisper-quiet zone heating. Highest efficiency (COP up to 4.1) — best for occupied offices.
🏢 Ceiling Cassette
4-way blow ceiling cassettes for open-plan floors and showrooms — even, discreet overhead heating with big capacity (up to 27,300 BTU/hr).
Why Heat-Pump Air Conditioning Beats Traditional Heaters This Winter
When the temperature drops, the natural reflex is to reach for an electric fan heater or crank up the central heating. But a portable air conditioner with a heat-pump heating mode is one of the most efficient ways to warm a workshop, warehouse or office — here's why it outperforms traditional heaters and whole-building central heating through the winter months.
Up to 3× More Efficient
Heat pumps move heat rather than generate it, delivering around 3 units of heat for every 1 unit of electricity (COP ≈ 3). A traditional electric fan heater only gives 1:1 — so the same kilowatt-hour goes three times further with heat-pump AC.
Lower Running Costs
Because of that efficiency, warming a space with a heat-pump portable air conditioner typically costs a fraction of running equivalent resistive electric heaters — and under current energy prices it routinely undercuts gas central heating for the area you actually use.
Heat Only Where You Need It
Why heat the whole factory to take the chill off one packing bay? Portable heat-pump AC warms the zone you’re working in, so you’re not paying to heat empty aisles, racking and stock.
Plug-and-Play, No Installer
No plumber, no flue, no annual service and no disruption. Wheel it in, plug it into a standard 13A socket, and you have instant heat — ideal for cold snaps, temporary work areas and shift-start warm-ups.
Dries As It Warms
Heat mode still dehumidifies, pulling moisture out of the air as it heats. That cuts the condensation and damp that cause rust, slippery floors and mould — protecting machinery, stock and buildings through winter.
One Unit, Two Seasons
The same 4-in-1 unit cools in summer and heats in winter, plus dehumidifies and fans. One capital purchase covers year-round climate control — far better value than a heater that sits idle for eight months.
The bottom line: For workshops, warehouses and factory floors that only need warmth in specific zones — or for businesses that want to avoid the cost and carbon of running full central heating all winter — a portable heat-pump air conditioner is the smarter, cheaper, more flexible way to keep working through the cold months.
