Systems & technology

How our systems work — and what they can do.

From cooling one room to several, and heating your home when the seasons turn — here's what's actually going on inside the equipment we install.

System types

Single-split and multi-split systems.

The difference comes down to how many rooms one outdoor unit can serve.

OUTSIDE INSIDE OUTDOOR UNIT INDOOR UNIT
1 room cooled

Single-split

One outdoor unit paired with one indoor unit, joined by a short pipe run through a single, discreet hole — right behind the unit.

BEDROOM LIVING ROOM KITCHEN BEDROOM OUTSIDE
3 rooms cooled

Multi-split

One outdoor unit, with independent pipe runs along the outside of the house feeding each indoor unit — still just a single small hole, right behind its own unit. Most standard multi-split systems support up to six indoor units from one outdoor unit, with bigger systems supporting more.

Did you know?

Not just cooling — a hyper-efficient heater too.

Every system we install is a heat pump. In summer it pulls heat out of your room and dumps it outside; in winter it reverses the cycle, drawing heat from the outside air — even cold air — and pumping it into the room. It's built into the unit as standard, at no extra cost.

Cooling mode

The indoor coil absorbs heat from the room; the outdoor coil releases it outside, leaving the room cool.

INSIDE OUTSIDE ← HEAT
Winter

Heating mode

A reversing valve swaps the coils' jobs: the outdoor coil now absorbs heat from the air, the indoor coil releases it into the room.

The basic science

It's the same principle as your fridge — just working in reverse.

A heat pump doesn't create heat from nothing — it moves it, using a refrigerant that cycles between liquid and gas. That's why it can put out far more heat energy than the electricity it consumes.

01

Compress

The refrigerant gas is squeezed by the compressor, which raises its temperature and pressure sharply.

02

Condense

The hot gas passes through a coil and gives up its heat to the air around it, turning back into a liquid.

03

Expand

The liquid passes through a valve, dropping its pressure and temperature sharply.

04

Evaporate

The cold refrigerant absorbs heat from the air around it and turns back into a gas — then it repeats.

A reversing valve is what makes it two-way: it decides which coil does the condensing and which does the evaporating. Flip it, and the coil that was heating your room starts cooling it instead — same system, same refrigerant, opposite job.

Up to 4x more efficient

Because it moves heat rather than generating it from raw electricity, it can produce three to four times more heat than the power it uses to run — far more efficient than a plug-in electric heater.

Nothing extra to fit

It's the same unit you already have for cooling. There's no second appliance to buy or install — the heating is simply switched on.

Great for the gaps

Ideal for topping up a room in spring and autumn, or heating spaces central heating struggles to reach — a home office, conservatory or loft conversion.
