Why air-to-air

One Quiet Unit. Four Jobs.

Cooling in summer

Instant, quiet cooling on the hottest days — set the room to exactly the temperature you want.

Heating for less in winter

A SCOP of ~4.0 means every kWh of electricity delivers about four of heat — the 3.5kW model provides around 3.8kW of warmth.

Cleaner, drier air

Built-in filtration and dehumidifying modes cut pollen, dust and damp year-round.

Installation planning

Installation requirements depend on the property and chosen system. Spark installation dates and service details will be confirmed when this range launches.

Run Your Comfort on Your Own Energy

Air-to-air heat pumps use electricity for heating and cooling. Solar and battery storage can supply some of that electricity, depending on generation, usage and the system design. Heating and cooling products are shown here as a preview.

System compatibility, controls and monitoring will be confirmed when the range launches.

Gas Boiler vs Air Conditioning — An Illustration

Explore an illustrative comparison using the assumptions below. Actual heating costs depend on your home, equipment, usage and tariffs.

Your yearly gas heating spend £1,100/yr
How this estimate is calculated

Illustration assumes gas at 7.33p/kWh, 85% boiler efficiency, heat-pump SCOP 4.0 and electricity at 26.11p/kWh. Solar/battery heating uses an assumed effective cost of 2p per kWh of heat. Carbon factors: gas 0.183 and electricity 0.07 kg CO₂/kWh. Installation and finance costs are excluded.

Air Conditioning Questions, Answered

What is an air-to-air heat pump?

It's what most people call air conditioning — a quiet wall-mounted indoor unit paired with an outdoor unit. It cools in summer, heats highly efficiently in winter and filters your air year-round.

Can it really heat my home in winter?

Yes. These units are heat pumps with a seasonal efficiency (SCOP) of around 4.0 — every kWh of electricity delivers about four of heat, and they deliver more heat than their cooling rating. They keep working well below freezing.

Is there a grant for air-to-air heat pumps?

Spark is not confirming grants or tax treatment for this preview range. Any available support and its eligibility conditions will need to be checked against the scheme rules and chosen installation when the service launches.

What about hot water?

Air-to-air systems heat and cool your rooms but don't heat water. Most homes keep their existing boiler or cylinder for hot water — or pair the system with an air source (air-to-water) heat pump like the EcoFlow PowerHeat.

How long does installation take?

Timing depends on the property and system. Spark is not taking heating or cooling installation bookings yet; service details will be confirmed when the range launches.

How noisy is it?

Indoor units run from around 22 dB(A) on their quietest setting — quieter than a whisper — and the outdoor unit is no louder than a modern fridge from a few metres away.

“The install team turned up on the coldest, wettest day in months and just cracked on, all in good humour, then took me through the monitoring app. Brilliant.”
