Are Air-to-Air Heat Pumps Suitable for Older Homes in Derbyshire?

Derbyshire has no shortage of characterful properties — from traditional stone cottages in Matlock and Bakewell to Victorian terraces in Derby and Edwardian homes across Belper, Wirksworth, Ripley and Chesterfield. Many homeowners in these older properties are now exploring whether renewable technology, including air-to-air heat pumps, can help reduce their energy bills while improving comfort levels. But the big question remains: are air-to-air heat pumps suitable for older homes in Derbyshire?

The short answer is yes — in most cases, air-to-air heat pumps are highly suitable for older homes, often far more so than air-to-water systems. They are flexible, fast-acting, and do not require the high insulation levels often needed for traditional wet-system heat pumps. Let’s explore why older properties across Derbyshire are increasingly turning to air-to-air heat pump systems for efficient, modern heating and cooling.

Understanding Air-to-Air Heat Pumps

An air-to-air heat pump extracts heat from the outside air and uses it to warm the indoor space. In summer, the process reverses, providing cooling. Instead of heating radiators or underfloor pipes, air-to-air units deliver warm or cool air directly into the room via internal air-handling units.

Because of this, they are:

• Fast to heat

• Quick to install

• Ideal for properties without modern heating systems

• Able to provide both heating and cooling all year round

For Derbyshire homeowners with older properties, these advantages make air-to-air heat pumps an excellent option.

Why Air-to-Air Systems Work Well in Older Properties

Many renewable heating systems come with the misconception that they require ultra-modern homes with perfect insulation and airtightness. While this can be true for some technologies, air-to-air heat pumps are different.

Here’s why they are often a perfect match for older Derbyshire homes:

1. They Don’t Rely on High Insulation Levels

Traditional cottages, farmhouses and Victorian terraces typically have:

• Solid brick or stone walls

• Single-skin construction

• Older windows

• Loft insulation that varies by age

Because air-to-air systems deliver warm air directly into the room, they do not rely on water-based heating infrastructure, which can struggle in poorly insulated spaces. Even older homes with average insulation benefit from efficient heating and faster warm-up times.

2. No Need for Radiators or Pipework

Unlike air-to-water heat pumps, air-to-air units do not require:

• Radiator upgrades

• Extensive plumbing work

• Major heating redesigns

This makes them perfect for:

• Period homes that cannot easily accommodate new pipework

• Heritage or listed properties

• Homes with small rooms where radiators take up valuable wall space

• Extensions, lofts or converted rooms

For older Derbyshire homes where retrofitting pipework would be costly or impractical, an air-to-air system avoids all such complications.

3. Quick, Non-Disruptive Installation

Most installations take just one day.

This is invaluable for homes where:

• Floors must not be lifted

• Walls cannot be chased

• Disruption must be minimal

• The property layout makes traditional heating changes difficult

Air-to-air systems only need an indoor unit, a small outdoor unit and a narrow pipe connection — meaning even cottage-style layouts can accommodate them.

4. Dual Heating and Cooling Is a Major Benefit

Older Derbyshire homes can be:

• Cold and draughty in winter

• Too warm upstairs in summer

• Built in valley or hillside areas where temperatures fluctuate

An air-to-air heat pump addresses both problems by offering heating in the winter and cooling during hot weather — something traditional heating systems cannot do.

5. Improved Air Quality for Older Buildings

Older homes often suffer from:

• Damp or condensation

• Stale air

• Dust build-up

• Pollen entering through older windows

Air-to-air heat pumps filter and circulate the air, reducing allergens, improving ventilation and contributing to a healthier indoor environment.

What About Listed Buildings or Conservation Areas?

Derbyshire has many conservation zones and Grade II listed properties, especially in areas like:

• Bakewell

• Matlock Bath

• Cromford

• Ashbourne

• Duffield

• Rowsley

For listed properties, external changes must often be approved — but installing compact, well-placed outdoor units is usually possible with the correct permissions. Air-to-air systems are generally easier to approve than traditional external units because they are smaller, quieter and require minimal alteration to the structure.

Midland Heat Pumps can advise on placement and planning requirements.

Energy Efficiency Benefits for Older Derbyshire Homes

Older homes typically have higher heating demands due to draughts, older windows and thicker walls. Because air-to-air heat pumps are extremely efficient — often producing 3-4 units of heat for every 1 unit of electricity — they help offset these higher heating requirements and reduce energy bills.

Homeowners often report:

• Lower electricity costs

• More consistent room temperatures

• Faster warm-up times compared to night-storage heaters or panel heaters

• Better comfort in extensions or poorly heated rooms

This makes them ideal replacements for:

• Old electric storage heaters• Electric panel heaters• Oil-fired heating• Bottled gas systems• Open fires or log burners used as primary heating

Installation Considerations for Older Homes

Although air-to-air systems suit older homes extremely well, there are a few key considerations:

1. Finding the Best Position for Indoor Units

Homes with smaller rooms, beams, sloped ceilings or irregular layouts may require creative placement. Professional installers ensure airflow is optimised.

2. Discreet Outdoor Unit Placement

Outdoor units are compact and quiet, but placement matters. They can often be positioned:

• At ground level

• On a rear wall

• Behind outbuildings

• In gardens

• On brackets in unobtrusive areas

3. Electrical Requirements

Most older homes meet the electrical needs for an air-to-air heat pump, but an installer will confirm supply suitability during a site survey.

4. Insulation Upgrades (Optional)

Not essential — but improving loft insulation or draught-proofing can enhance performance and comfort.
