Heat Pump vs. Traditional Heating: A Comprehensive Winter Comfort Comparison
When winter arrives in Ireland, most homeowners face the same question: how do I keep my home warm without breaking the bank? For decades, the answer has been straightforward – oil boilers, gas heating, or electric radiators. But times are changing, and heat pumps have rapidly become the smarter choice for Irish homes. If you’re wondering whether a heat pump is right for your home, especially in our cold Irish winters, this guide breaks down everything you need to know.
How Heat Pumps Work – Even in Cold Irish Weather
One of the biggest misconceptions about heat pumps is that they don’t work well when it’s cold. In reality, heat pumps are specifically designed to extract heat from the air – even when temperatures drop below freezing.
Here’s the science: Air source heat pumps work by extracting thermal energy from outside air and concentrating it to heat your home. Even at -15°C, there’s still heat energy in the air that a heat pump can extract and use. This is why they’re so effective in Ireland’s climate.
The efficiency of a heat pump is measured by its Coefficient of Performance (COP). According to SEAI research, air source heat pumps typically achieve a COP of 3-4, meaning they produce 3-4 units of heat for every 1 unit of electricity consumed. For seasonal performance (SCOP), which accounts for varying weather throughout the year, heat pumps in Ireland typically deliver an SCOP of 3 or higher – significantly more efficient than traditional heating systems.

Running Costs: Heat Pumps vs. Traditional Heating
Let’s talk about what really matters to most homeowners – the cost of keeping warm.
Traditional heating systems (oil boilers, gas boilers, electric radiators) convert fuel into heat at roughly 85-95% efficiency. That means you’re losing 5-15% of your energy investment. Heat pumps, by contrast, move existing heat rather than creating it, making them far more economical to run.
The financial advantage depends on your current heating system:
» Oil Heating vs. Heat Pump
Oil heating is typically the most expensive option for Irish homeowners. With volatile oil prices and the need for regular deliveries, costs can spike unexpectedly. A heat pump running on electricity – even at current rates – is significantly cheaper to operate. SEAI data shows that heat pumps offer the lowest running costs compared to oil, gas, and electric heating alternatives.

» Gas Heating vs. Heat Pump
Gas is cheaper than oil, but still more expensive than running a modern heat pump. The efficiency advantage of heat pumps – producing 3-4 units of heat per unit of electricity – means lower monthly bills, even accounting for electricity costs.
» Electric Radiators vs. Heat Pump
If you’re currently using electric radiators, a heat pump is a no-brainer. Electric radiators are essentially 100% efficient at converting electricity to heat, but they don’t benefit from the COP advantage that heat pumps provide. A heat pump will reduce your heating costs by approximately 50-70% compared to traditional electric heating.
Real-World Performance: Temperature Data from Irish Homes
Theory is one thing; real-world performance is another. When Leetherm installs heat pumps in Irish homes, we see dramatic improvements in comfort and consistency.
Typical improvements include:
- Elimination of cold spots: Homes with poor insulation or traditional heating often have temperature variations of 5-10°C between rooms. Heat pumps, combined with proper system design, deliver consistent warmth throughout the home.
- Faster warm-up times: Modern heat pumps heat homes more quickly than traditional boilers, especially when paired with upgraded insulation and radiators.
- Improved comfort in winter: Because heat pumps deliver gentle, consistent heating rather than intermittent bursts, homes feel warmer and more comfortable at lower thermostat settings.
The key to maximising these benefits is ensuring your home is properly insulated and your heat pump system is correctly sized and installed. This is why Leetherm always conducts a comprehensive home energy assessment before recommending a heat pump solution.
Addressing Common Heat Pump Misconceptions
» Myth 1: “Heat Pumps Don’t Work in Irish Winters”
Reality: Heat pumps are designed to work in cold climates. SEAI research confirms that air source heat pumps maintain good efficiency even at temperatures well below freezing. Ireland’s winter temperatures rarely drop to the levels where heat pump efficiency becomes a concern.

» Myth 2: “Heat Pumps Are Too Expensive to Install”
Reality: SEAI grants significantly reduce the upfront cost. Depending on your home type and circumstances, grants can cover a substantial portion of the installation cost, making heat pumps more affordable than many homeowners realise.
» Myth 3: “Heat Pumps Are Noisy”
Reality: Modern heat pumps are remarkably quiet – typically operating at 40-50 decibels, similar to a quiet conversation. Proper installation by SEAI-registered contractors ensures minimal noise.
The Power of Integration: Heat Pumps + Insulation + System Upgrades
A heat pump alone is effective, but it’s truly transformative when combined with other energy efficiency measures.
Heat Pumps + Better Insulation
Insulation reduces the amount of heat your home loses, which means your heat pump doesn’t have to work as hard. The result? Lower running costs and superior comfort. A home with upgraded attic insulation, cavity wall insulation, and improved windows will see dramatically better performance from a heat pump than a poorly insulated home.
Heat Pumps + Upgraded Radiators & Hot Water Systems
Modern heat pumps work most efficiently at lower flow temperatures than traditional boilers. Upgrading your radiators and hot water tank ensures your system operates at peak efficiency, maximising your savings and comfort.
Heat Pumps + Smart Controls
Modern heating controls allow you to manage your heat pump remotely, set schedules, and optimise performance based on your lifestyle. This adds another layer of cost savings.
