Heat Pump Myths Busted: Separating Fact from Fiction in 2026

If you’ve researched air source heat pumps in the UK, chances are you’ve seen some strong opinions online. From social media comments to newspaper headlines, heat pumps often get criticised — sometimes unfairly.

The truth is, many of the negative views are based on outdated information, poor installations, or simple misunderstandings. In this article, we’ll bust the most common heat pump myths and explain what homeowners in Cheshire really need to know in 2026.

Myth 1: “Heat Pumps Don’t Work in Cold Weather”

This is one of the most persistent myths — and it’s simply false.

Modern air source heat pumps are designed to work efficiently even in freezing temperatures. Countries like Norway, Sweden and Finland — where winters are far colder than the UK — have been using heat pumps successfully for decades.

✔ Heat pumps extract heat from the air, even when it’s below zero
✔ UK winters are mild compared to countries with high heat pump adoption
✔ Performance only drops slightly in extreme cold — they still function

The reality: A correctly sized and installed heat pump works perfectly well in UK weather, including Cheshire winters.

Myth 2: “Heat Pumps Are Too Expensive to Run”

Electricity costs more per unit than gas (which is a political choice and won't last for ever) — but heat pumps don’t work like boilers.

Heat pumps are incredibly efficient. For every 1 unit of electricity, they typically produce 3–4 units of heat (known as a COP of 3–4).

That means:

• Lower overall energy consumption
• More stable heating costs
• Even bigger savings when paired with solar panels or a home battery

The reality: Running costs are comparable to — or lower than — gas boilers, especially in well-insulated homes.

Myth 3: “Heat Pumps Are Hard to Install or Need Loads of Space”

Many homeowners worry they’ll need a massive garden or a full home renovation.

In reality:

• The outdoor unit is about the size of an air-conditioning unit
• Indoors, the boiler is replaced with a compact heat pump unit, usually alongside a hot water cylinder designed for heat pump systems.
• Most homes don’t need significant structural changes

The reality: Most UK homes — including typical Cheshire properties — can accommodate a heat pump with minimal disruption when designed properly.

Myth 4: “You Don’t Get Proper Heating or Hot Water”

This myth often comes from early installations or poorly designed systems.

A modern, professionally installed heat pump will:

• Heat your home evenly and consistently
• Provide reliable hot water for daily use
• Avoid the harsh on/off cycling of gas boilers

Heat pumps work best with steady, low-temperature heating, which is why they feel different — not worse.

The reality: You get the same comfort, just delivered more efficiently.

Myth 5: “It’s Better to Wait Until the Technology Improves”

Heat pump technology is already mature, proven, and improving incrementally, not revolutionarily.

Waiting could mean:

• Missing out on the £7,500 Boiler Upgrade Scheme grant
• Losing access to 0% VAT on heat pump installations (currently extended to 2027)
• Paying higher energy bills in the meantime

The reality: Heat pumps are ready now, and government incentives may not always be this generous.

Myth 6: “Heat Pumps Aren’t Suitable for Older Homes”

Many Cheshire homes are older — and this myth puts people off unnecessarily.

While insulation helps, older homes can absolutely run heat pumps successfully with:

• Proper heat loss calculations
• Radiator upgrades where needed
• Good system design

The reality: Age doesn’t disqualify your home — design quality matters far more.

Why Do Heat Pumps Get So Much Bad Press?

Most negative stories come down to:

• Poorly installed systems
• Incorrect sizing
• Lack of homeowner education
• Click-driven headlines and comment sections

A heat pump is not a “plug-and-play boiler replacement”. When done right, it’s one of the most efficient heating systems available.

The Bottom Line

Heat pumps are:
✔ Efficient
✔ Reliable
✔ Well-suited to UK homes
✔ Supported by government grants
✔ A proven long-term heating solution

Don’t let myths or online negativity stop you from making a smart, future-proof decision for your home.
