Couple In Yorkshire Told They Needed A Bigger Heat Pump – They Didn't The Problem
A Yorkshire couple were struggling to keep warm in winter and had been told they needed a larger heat pump. An independent review found the heat pump was correctly sized — the problem was how it was being used.

How Do Heat Pumps Help Households and the Planet?
Heat pumps have become one of the most discussed topics in home heating over the last few years, and for good reason. They sit at the intersection of two things most UK homeowners care about: keeping their home warm affordably, and reducing the environmental impact of how they live. Understanding how heat pumps actually deliver on both of those things, and where the caveats lie, helps homeowners make better decisions and get more from their systems once they are installed.
How a Heat Pump Works and Why Efficiency Matters
A heat pump does not generate heat by burning fuel. Instead, it moves heat that already exists in the outside air and transfers it into your home. The process is similar in principle to how a fridge works, only in reverse. Because the heat pump is moving energy rather than creating it from scratch, it can deliver significantly more heat energy than the electrical energy it consumes to run. This relationship between energy in and heat out is measured as the Coefficient of Performance, or COP. A heat pump operating at a COP of 3 is delivering three units of heat for every one unit of electricity used, which makes it far more efficient than any gas or oil boiler, which burns fuel to produce heat at a theoretical maximum of one unit out for every unit burned.
In practice, a well-installed air source heat pump operating at typical UK conditions will run at a seasonal COP of somewhere between 2.5 and 4, depending on the outdoor temperature, the flow temperature the system is set to, and how well the installation has been designed and commissioned. That efficiency is precisely why heat pumps matter both to households looking to reduce bills and to policymakers trying to decarbonise heating at a national level.
How Heat Pumps Benefit Households
The most direct benefit for a household is reduced energy consumption to deliver the same amount of warmth. A heat pump running efficiently uses considerably less energy per unit of heat delivered than a gas boiler and dramatically less than an oil or electric resistance heating system. For households on oil or LPG, this difference can be particularly significant because those fuel sources are expensive per unit of energy and subject to sharp price volatility that electricity is not exposed to in the same way.
Running costs on a heat pump also behave differently from those on a boiler. Because a heat pump operates continuously at lower flow temperatures rather than firing in short, intense bursts, it tends to maintain a more stable and even warmth throughout the property. Many homeowners who switch from oil or gas describe a qualitative improvement in how the house feels, particularly if the system has been correctly sized and commissioned. Our article on why does my heat pump feel less powerful than my old boiler explains what is normal, what the signs of genuine underperformance look like, and when it signals a system problem that needs addressing.
The savings a household actually experiences depend heavily on how the system has been set up. Flow temperature is one of the most important variables. A heat pump running at a lower flow temperature, typically between 35°C and 45°C, operates significantly more efficiently than one set to replicate the higher temperatures of a gas boiler system. Understanding how much a heat pump should cost to run in winter helps homeowners benchmark whether their system is performing as it should, or whether high bills are a signal that something in the configuration or installation needs investigating. Getting the commissioning right is not a minor detail it is the difference between a system that saves money and one that costs more than the boiler it replaced.
There is also the question of what happens as the UK electricity grid continues to decarbonise. As more renewable generation comes onto the grid, every heat pump in the country automatically becomes cleaner over time without any action required from the homeowner. That is not true of any fossil fuel heating system, where the carbon intensity of the fuel is fixed by the chemistry of combustion.
How Heat Pumps Benefit the Planet
Heating buildings is responsible for a substantial share of the UK's total carbon emissions. Most of that comes from burning natural gas in domestic boilers. Replacing gas combustion with electricity-driven heat transfer reduces direct carbon emissions from the home immediately, and as the grid cleans up, the indirect emissions from generating the electricity to run the heat pump also fall.
For homes currently on oil or LPG, the environmental benefit of switching to a heat pump is even more pronounced. Oil heating produces significant carbon emissions per unit of heat delivered, and the supply chain involved in extracting, refining, and distributing heating oil adds to that footprint in ways that grid electricity does not. A well-installed heat pump eliminates all of that.
The scale of the benefit at a household level translates to a meaningful national impact when multiplied across millions of homes. The UK government's target of significantly increasing the number of heat pump installations each year reflects this, and the Boiler Upgrade Scheme grant, which currently offers up to £7,500 towards the cost of a new air source heat pump, was designed specifically to accelerate the transition away from gas and oil boilers by making the upfront cost more manageable.
Why Correct Installation Determines Whether the Benefits Are Realised
The environmental and financial benefits of a heat pump are not automatic. They depend on the system being sized correctly for the property, installed to the right specification, and commissioned properly. A heat pump that has been oversized, set to run at unnecessarily high flow temperatures, or installed into a system that has not been designed to work with heat pump operating conditions will not deliver the efficiency it is capable of. In some cases, a poorly installed heat pump can actually cost more to run than the gas boiler it replaced, which is why independent advice and proper technical review matter so much.
Our article on 7 signs your heat pump may not be installed correctly covers the most common indicators that something is wrong with an installation, and our article on what happens if a heat pump is oversized explains one of the most frequent and least obvious causes of poor performance.
A heat pump that is working as intended is one of the most effective things a household can do to reduce both its carbon footprint and its long-term energy costs. The gap between that outcome and a poorly installed or badly configured system is significant, which is why getting the fundamentals right from the outset, or identifying and fixing problems on an existing installation, is the most important step any homeowner can take.
