Ideal Logic Air heat pump

The Ideal Logic Air is a monobloc air source heat pump sold in four outputs: 4kW, 5kW, 8kW and 10kW¹. It is Ideal Heating's flagship heat pump line, and the maker describes it as quiet, compact and highly efficient². The headline efficiency claim is a lab-tested SCOP of up to 5.19, which Ideal presents as over 500% efficiency under test conditions³.

The unit is a monobloc, meaning all components other than the hot water cylinder sit in a single outdoor box⁵. That single fact shapes most of what follows: no refrigerant pipework enters the house, the cylinder is a separate purchase, and the outdoor unit carries the compressor, the controls and the noise. Ideal sells it as part of a package with a pre-plumbed cylinder and the Halo Air thermostat⁶.

For a household, the Logic Air replaces gas or oil combustion with electricity, which removes the gas connection and the flue but keeps a dependence on the electricity grid and a supplier. The warranty terms are conditional on registration within 30 days and annual servicing, and the longest cover attaches to the control box rather than the heat pump itself⁷.

Ideal Heating: the company behind the Logic Air

Ideal Heating is a long-established British heating brand whose main business has been gas boilers, and the Logic Air is its move into low carbon heating. The company positions the heat pump alongside its boiler range rather than as a replacement for the business, and it also sells a hybrid version that combines the Logic Air monobloc with a Logic gas boiler in one system⁴. That hybrid is described as combining the market leading gas boiler range with the flagship Logic Air monobloc air source heat pump, with the heat pump acting as system master⁴.

Support is a stated part of the offer. Ideal says it has dedicated heat pump engineers covering every corner of the UK, first install assisted commissioning, a full parts and labour warranty, and a UK-based contact centre open 364 days a year¹². Distributor listings repeat the 364 day figure for customer service and technical support, and describe the range as designed to deliver efficient, simple and reliable low carbon heating in homes throughout the UK, with the warranty team based in the UK¹⁰.

The company's own published contact numbers conflict. One gives 01482 492251 and another gives 01482 498660, so neither can be presented as the single correct number⁷. Householders should check Ideal Heating's current contact page rather than rely on either figure.

What this means for independence is mixed. A UK-based support operation and a British brand shorten the service chain, but the household still depends on Ideal Heating for parts, warranty administration and the Connect registration portal, and on a trained installer for commissioning. The heat pump itself is a manufactured product with a single supplier behind it.

The Logic Air range: 4kW, 5kW, 8kW and 10kW monobloc units

Ideal sells the Logic Air in four versions: 4kW, 5kW, 8kW and 10kW¹. The two smaller units share a casing of 798 x 1095 x 521mm and a weight of 86kg, while the 8kW and 10kW units measure 1008 x 1095 x 518mm and weigh 110kg¹⁰. The physical step between the 5kW and 8kW models is therefore a real one: the larger pair needs a wider footprint and a heavier mounting.

Published capacities at the standard test point of air 7°C and water 35°C are 4kW, 5kW, 8.2kW and 10.3kW across the four models, with the 4kW unit drawing 0.75kW of electrical input at that condition⁴. Heating flow and return connections are given as 1 inch BSP on the range, and 28mm on the specification sheet, so the pipework size should be confirmed against the current document for the model being fitted⁴.

All four run on a 230V 50Hz single phase electrical supply³. That is the ordinary domestic supply, so no three phase connection is required, though whether the existing supply and fuse rating are adequate is a separate question settled at survey.

Sizing is not a matter of picking the nearest number to the floor area. The output that suits a property follows a room-by-room heat loss calculation, and the range's four steps exist to match that result. A house that calculates between two of those steps sits between the 5kW and 8kW units, and the choice between them turns on design flow temperature, hot water demand and how much of the heating season the unit runs at part load. More on this is at heat pump sizing.

Efficiency: SCOP up to 5.19 and A+++ rated

Ideal's headline figure is a lab-tested SCOP of up to 5.19, presented as a way to reduce electricity use without sacrificing warmth⁴. The same figure appears in the range brochure as SCOP 5.19 for the 10kW model³. Ideal also states the Logic Air is capable of over 500% efficiency under lab-tested conditions¹⁶.

The ErP rating is A+++ at 35°C flow temperature and A++ at 55°C, across the models³. That split is the important part. The A+++ figure applies to a system running at 35°C, which suits underfloor heating or generously sized radiators; at 55°C, which is closer to what many existing radiator systems need, the rating drops a full class. The efficiency of an installed Logic Air therefore depends less on the badge than on the flow temperature the system is designed and balanced to run at.

Model-level COP figures at the A7/W35 test point are published as 5.34, 5, 5.19 and 4.9 across the four outputs, and the 8kW unit is listed at a COP of 5.19 at that condition⁴. These are single-point laboratory figures, not seasonal performance in a real house. SCOP is the more useful number for a household, and even SCOP is a modelled value rather than a metered one.

The gap between the headline and reality is the same for every maker. A heat pump achieves its rated efficiency when the emitter system can deliver the required heat at a low flow temperature, which means adequate radiator output or underfloor heating, a well-insulated and draught-proofed envelope, and controls that run the unit steadily rather than in short bursts. Ideal's own weather compensating controls are designed to do the last of those⁵. The wider explanation of these measures is at heat pump efficiency.

A monobloc with everything outdoors except the cylinder

The Logic Air is a monobloc air source heat pump, and Ideal describes the monobloc design as combining all the components, other than the hot water cylinder, into a single outdoor unit⁵. The specification sheet labels it a monobloc air source heat pump, and the product pages describe it as a quiet, compact and highly efficient monobloc heat pump².

The practical consequence is that the refrigerant circuit stays sealed inside the outdoor casing. Only water pipework crosses the wall, which is the same arrangement described for other monobloc units, where the connection is by water piping only, eliminating the need for refrigerant piping¹⁷. That removes the need for a refrigerant-qualified engineer to work inside the house and removes the risk of a joint leaking in a bedroom or loft.

The cylinder is the part that stays indoors. Ideal's package combines the monobloc heat pump, a pre-plumbed heat pump cylinder and the Halo Air thermostat, and one case study describes the heat pump coupled with a 180 litre pre-plumbed and pre-wired cylinder⁶. Domestic hot water is described as hot, efficient and fast re-heating with the Ideal heat pump cylinder range²⁰. A pre-plumbed cylinder arrives with much of the pipework and controls already assembled, which shortens installation time but fixes the layout to the cylinder's own arrangement.

For independence, the monobloc is a modest advantage: fewer trades, less refrigerant handling, and a simpler boundary between the manufacturer's sealed unit and the householder's wet system. The dependence that remains is on the manufacturer for the sealed circuit, since a refrigerant fault cannot be dealt with by a general plumber. The comparison with split systems is at monobloc and split heat pumps.

Controls and smart compatibility: Halo Air, weather compensation and solar PV

The Logic Air runs on smart weather compensating controls that adjust output to suit the current climate, and the range is described as smart grid and solar PV compatible⁵. The Logic Air Heat Pump Control Box is compatible with Halo Air and is itself listed as smart grid compatible and solar PV compatible⁷. The hybrid leaflet lists an integrated controller within the heat pump⁴.

Weather compensation is the core of it. Rather than switching the heat pump on and off against a room thermostat, the control adjusts the flow temperature according to the outdoor temperature, so the unit runs longer at a lower temperature and condenses more of its output into useful heat. That is what makes the A+++ at 35°C rating reachable in practice.

Solar PV compatibility means the heat pump can be run from self-generated electricity, and smart grid compatibility means it can respond to signals from a tariff or network. Both depend on the household having the panels, the inverter and, in most cases, a supplier offering a suitable tariff. The heat pump does not generate anything itself.

The controls are the point at which a heat pump's independence is most conditional. Weather compensation works locally and needs no internet connection. Smart grid response, remote monitoring and any app-based scheduling depend on a broadband connection, the manufacturer's platform and a third party's servers. A household that wants to keep control inside the house should understand which functions survive a lost connection and which do not. More on this is at heat pump controls.

Quiet Mark certification and permitted development

All Logic Air heat pumps are Quiet Mark certified, and the range is described as Quiet Mark approved³. Ideal states that as a Quiet Mark Approved device it will not be a disturbance within the home or to neighbours⁹. The certification covers the 4kW, 5kW, 8kW and 10kW models individually¹⁴.

Quiet Mark certification is an independent noise mark, and it is awarded per product rather than per brand. Other heat pumps hold it too, including the NIBE S1156-13 and LG Therma V R290 monobloc models²². It is a useful signal that the unit has been measured against a noise criterion, but it is not a statement about the noise at a particular installation, which depends on siting, distance from boundaries and the surface the unit is mounted on.

On planning, Ideal states the Logic Air is small enough for permitted development with the local planning authority³. Permitted development rights for heat pumps are set by national rules and differ between England, Scotland, Wales and Northern Ireland, and they carry conditions on siting, number of units and noise. Certification and a compact casing help, but they do not by themselves confirm that a specific installation is permitted. The rules by nation are set out at heat pump planning permission in England and the equivalent pages for Scotland, Wales and Northern Ireland, with the noise method at MCS 020.

Warranty, registration and annual servicing

The warranty position is a ladder with conditions at each rung. The Logic Air Heat Pump Control Box carries a 5 year parts and labour warranty, available when registered within 30 days of installation and serviced annually⁷. The Logic Air Hybrid carries a 2 year warranty on the same registration and servicing conditions, with terms and conditions applying⁹. The range is described generally as carrying a full parts and labour warranty³.

Registration runs through Ideal's Connect portal, and the 30 day window is a hard condition rather than a formality. Annual servicing is the second condition, and it is a continuing cost and a continuing relationship with an installer. Ideal's servicing design helps here: the range has remote system health checks, a factory-fitted magnetic and particle filter, all service components to one side of the heat pump, and all hydraulic servicing can be done inside the property¹². That last point matters in a British winter, since the engineer does not have to work on the outdoor unit for routine hydraulic work.

The support structure behind the warranty is a UK-based contact centre open 364 days a year, dedicated heat pump engineers covering every corner of the UK, and first install assisted commissioning¹². Those are maker statements about its own service operation.

For independence, the warranty is the clearest remaining tie. The household depends on Ideal Heating for parts and for the registration platform, and on a servicing engineer to keep the cover valid. The servicing and warranty relationship is examined at heat pump servicing and warranty.

Cost, the Boiler Upgrade Scheme and EDF tariff bundles

Ideal states the cost of a heat pump can be reduced by up to £7,500 if the household is eligible for the UK's Boiler Upgrade Scheme⁹. That is the grant figure the maker publishes, and it matches the scheme's own published level. The Boiler Upgrade Scheme funds installing a heat pump, biomass boiler or heat battery, and the fossil fuel heating systems it replaces include oil, gas, electric or LPG²⁴.

There is no published Ideal list price for a supplied and fitted Logic Air in the material available here, so prices are installer-quoted. What exists instead is a series of supplier offers. EDF and Ideal Heating launched a Heat Pump and Power Tracker tariff bundle in October 2024 offering free electricity in December 2025, a 7 year warranty and servicing package, and a 3 year tariff with six hours of discounted electricity daily²⁸. A separate EDF and Ideal offer gave £1,000 off Ideal air source heat pump systems to the first 100 eligible customers signing up before 24 November 2024, with installed systems from £3,500 after the Boiler Upgrade Grant²⁹. EDF later launched a zero standing charge Heat Pump and Save Tracker tariff for Ideal Heating air source heat pump customers, a one year tariff with no exit fees and guaranteed savings of at least £360 a year³⁰.

Those offers are dated and were limited by time or customer number, so they are evidence of what has been available rather than of current pricing. The grant position and the cost picture more broadly are at heat pump grants and heat pump cost.

Where the Logic Air fits, and what it does not settle

The Logic Air is a monobloc air source heat pump in four outputs, with a lab-tested SCOP of up to 5.19, an ErP rating of A+++ at 35°C and A++ at 55°C, Quiet Mark certification across the range, and a 5 year parts and labour warranty on the control box subject to registration and annual servicing¹. It works with radiators and underfloor heating, runs on a single phase 230V supply, and pairs with Ideal's own pre-plumbed cylinder and Halo Air thermostat⁵.

What it does for a household's energy independence is to move space heating and hot water off gas or oil and onto electricity, removing the flue, the gas connection and the fuel delivery. What remains is a dependence on the electricity grid and a supplier, on Ideal Heating for parts, warranty and the Connect platform, on an installer for commissioning and annual servicing, and on a broadband connection for any smart or remote function. The heat pump is a manufactured product from a single company, and the longest warranty term is conditional rather than automatic.

Two questions the material does not answer. The refrigerant used in the Logic Air is not named in the specification sheet or product pages, and the manufacturing location is not stated, though Ideal describes the range as designed for UK homes and a distributor describes the customer service and warranty team as UK-based³. Where a fact is not published, it should not be assumed.
