Heat Pumps Don’t Work? Here's What Most Homeowners Get Wrong
If you’ve spent any time researching renewable heating, you’ve probably come across claims that “heat pumps don’t work.”
It’s one of the most common questions we hear as a heat pump installer in Derby, serving homeowners across Derbyshire, Nottinghamshire, Staffordshire, and the wider East Midlands.
The truth is simple: heat pumps do work.
Modern air source heat pumps are successfully heating millions of homes across Europe and the UK and are becoming one of the most popular alternatives to gas boilers. When correctly designed and installed by an experienced heat pump installer in Derby, they provide reliable heating, hot water, and excellent energy efficiency throughout the year.
At The Thermal Heat Company, we install heat pumps across Derby, Burton upon Trent, Ashbourne, Belper, Matlock, Chesterfield, Nottingham, Ilkeston, Long Eaton, Ripley, and surrounding areas throughout the East Midlands.
Let’s separate fact from fiction…
Why do some people think heat pumps don’t work?
Many negative experiences and stories can traced back to one or all the following issues:
Poor system design
Incorrect installation
Unrealistic expectations
A heat pump is not simply a boiler replacement. The system should be designed to suit the property’s heating requirements, insulation levels and radiator sizes. When shortcuts are taken, performance can suffer.
Do Heat Pumps Work throughout Winter?
Modern air source heat pumps are designed to run in low outdoor temperatures and continue extracting heat from the air even during winter conditions.
In fact, many systems continue to operate efficiently when temperatures drop below freezing.
While a heat pump works differently from a traditional gas boiler, it can keep your home warm and comfortable throughout the colder months.
Are Heat Pumps Expensive to Run?
Not necessarily...
The running cost of a heat pump depends on:
- Property insulation
- Heating demand
- Electricity tariffs
- System design
- User controls
Because heat pumps are highly efficient, they can produce several units of heat for every unit of electricity consumed.
This efficiency is one of the reasons heat pumps are becoming increasingly popular as energy prices continue to fluctuate.
The best way to describe it is that a heat pump is a long term investment.
Heat Pumps Work Even Better with Solar Panels, Battery Storage and EV Charging
One of the biggest advantages of a heat pump is how well it integrates with other renewable technologies.
Unlike a gas boiler, a heat pump runs on electricity, which means it can take advantage of electricity generated by solar panels and stored in home battery systems.
For homeowners looking to reduce their energy bills and carbon footprint, combining a heat pump with solar PV and battery storage can create a highly efficient home energy system.
Benefits include:
Using free electricity generated by your solar panels to help run your heat pump.
Storing excess solar energy in batteries for use during the evening.
Reducing reliance on energy imported from the grid.
Lowering overall household energy costs.
Future-proofing your home against rising energy prices.
Many homeowners are now creating fully integrated renewable energy systems that combine:
- Air source heat pumps
- Solar PV panels
- Battery storage
- Electric vehicle (EV) chargers
This allows a single system to provide heating, hot water, electricity generation, energy storage, and vehicle charging from renewable sources.
As the UK continues its transition towards cleaner energy, these technologies work together to help households become more energy independent while reducing running costs and emissions.
Why Some Heat Pump Installations Underperform
When people say their heat pump “doesn’t work,” there is usually an underlying reason.
- Incorrect Sizing
- A heat pump that is too small may struggle to meet demand during colder periods.
- Poor System Design
- Existing radiators and pipework may need upgrades to maximise performance.
- Lack of Commissioning
- Proper setup and optimisation are essential to ensure the system runs efficiently.
- User Education
Heat pumps work differently from boilers. Understanding how to use controls effectively can make a significant difference to comfort and efficiency.
Heat Pumps vs Gas Boilers
Both systems have their advantages, but heat pumps offer several benefits:
- Lower carbon emissions
- High energy efficiency
- Reduced reliance on fossil fuels
- Eligibility for the Boiler Upgrade Scheme
- Potential long-term savings
For many homeowners, a heat pump can provide a future-proof heating solution that aligns with the UK’s move towards cleaner energy.
The Importance of Choosing the Right Installer
A heat pump is only as good as the design and installation behind it.
Every property is different, which is why a detailed heat loss calculation and system design are essential before installation begins.
Working with an experienced installer helps ensure the system is correctly specified, installed, and commissioned for your home.
The Verdict: Do Heat Pumps Really Work?
Yes, heat pumps absolutely work.
The idea that “heat pumps don’t work” is usually based on poor installations, outdated information, or misunderstandings about how the technology operates.
When correctly designed and installed, a heat pump can provide reliable heating, hot water, and excellent energy efficiency throughout the year.
