Between technical specifications, system types, and installation issues, there are always many questions about heat pumps. We’ve compiled the most frequently asked questions from our customers, with clear answers and no technical jargon.
Heat pumps are one of the most efficient ways to make your home more comfortable and sustainable. But with all the technical specifications, different types of systems, and installation considerations, questions often arise. We’ve compiled the most frequently asked questions from our customers, with clear answers and no technical jargon.
A heat pump is a system that transfers heat from one place to another using electricity efficiently. Instead of generating heat through combustion (like a gas water heater), the heat pump extracts heat from the outside air, even at sub-zero temperatures, and transfers it to the interior of the home or to domestic hot water.
For every kilowatt of electricity consumed, a heat pump produces between 2 and 4 kW of thermal energy. This ratio is known as COP (Coefficient of Performance) and is the major economic advantage of heat pumps over any electric resistance or combustion system.
Heat pumps consume less energy, reduce electricity bills, and combine heating, cooling, and domestic hot water functions into a single unit, without the need for gas, a pressure regulator, or a chimney.
With the steady rise in gas prices and the decarbonization of the energy sector, switching to a heat pump offers both immediate savings and protection against future volatility in fossil fuel prices.
In most cases, yes. Reversible systems operate in heating mode in the winter and cooling mode in the summer. Efficiency in both modes is measured by two indicators: SCOP (Seasonal Coefficient of Performance) for heating and SEER (Seasonal Energy Efficiency Ratio) for cooling, the higher the better.
Annual maintenance is recommended and includes: cleaning filters, checking pressures, performing an electrical inspection, and monitoring refrigerant levels. Regular maintenance significantly extends the equipment’s lifespan and keeps efficiency at its peak.
On average, between 15 and 20 years. Proper use and regular maintenance are the factors that most influence durability. Well-maintained systems often have a longer-than-average lifespan.
Yes. Heat pumps significantly reduce energy costs and carbon emissions compared to older, inefficient systems. LEFE’s technical team evaluates your existing installation and presents the most suitable solution, including any necessary adjustments to the heat distribution network.
It depends on the type you choose:
Heat pumps enable significant savings on your energy bill. The return on investment typically ranges from 5 to 10 years, depending on energy rates, the system being replaced, and the home’s usage patterns. When combined with solar panels, the return can be substantially faster.
