Efficient electric heating that delivers 3–4kW of warmth for every 1kW you pay for — with cooling thrown in free for summer. Ideal for garden rooms, garages, conversions and extensions across Wiltshire.
Here's something most people don't realise: every modern split air conditioner is an air-to-air heat pump. The same unit that cools your room in July runs in reverse in January, pulling heat out of the outside air and moving it indoors. So when people search for a heat pump air conditioner, they're really describing one machine that does both jobs — and we install them across Swindon, Salisbury, Chippenham, Trowbridge and the whole of Wiltshire.
A plug-in electric heater converts electricity to heat at a strict 1:1 — every kilowatt of heat costs you a kilowatt of electricity. An air-to-air heat pump doesn't generate heat, it moves it, and that's far more efficient: a typical COP of 3–4 means 3–4kW of heat for every 1kW of electricity used. In plain terms, heating a room costs roughly a quarter to a third of what the same warmth costs from a fan heater, oil-filled radiator or electric panel. Our running costs guide works through real numbers.
Air-to-air heat pumps really shine in spaces the central heating never reached:
We install plenty of these for customers in Devizes and Marlborough who work from garden offices year-round — a single unit typically installed in a day.
Both are air-source heat pumps, but they deliver heat differently. An air-to-air system (what we install) blows warm air straight into the room through indoor units — no radiators, no hot water cylinder. An air-to-water system heats water for radiators, underfloor heating and your taps, and is the type that replaces a gas or oil boiler. One important note: air-to-air currently doesn't qualify for the Boiler Upgrade Scheme grant — that applies to air-to-water systems. The flip side is the upfront cost of air-to-air is a fraction of a wet system, and installation takes a day rather than a week. Our air-to-air heat pumps explained guide covers the choice in detail.
Buy an air-to-air heat pump for the heating and the cooling comes at no extra cost — same unit, same install. As Wiltshire summers keep getting hotter, that's an increasingly valuable bonus; it's the same equipment we fit as a standard air conditioning installation.
A worked example: a 2.5kW electric panel heater running 5 hours a day at 27p/kWh costs about £3.40 a day. An air-to-air heat pump putting out the same 2.5kW of heat draws roughly 0.7–0.8kW — about £1.00 a day for the same warmth. Over a winter, that difference pays for a good chunk of the installation.
Both are air-source heat pumps — they take heat from outside air. An air-to-air heat pump blows warm (or cool) air directly into the room through an indoor unit. An air-to-water heat pump heats water for radiators, underfloor heating and hot water cylinders. We install air-to-air systems.
Yes. Modern units extract useful heat from outside air down to around -15°C — far colder than a typical Wiltshire winter. Efficiency dips a little on the coldest days but stays well ahead of a plug-in electric heater.
Not for air-to-air. The Boiler Upgrade Scheme grant currently applies to air-to-water heat pumps that replace a boiler, not air-to-air systems. Air-to-air remains one of the cheapest heating installs outright though, with much lower upfront costs than a wet system.
