The outdoor heat pump unit is often overlooked in the winter because it “just works”. However, January is the ideal time to check whether it is clogged with leaves or other debris that can unnecessarily increase consumption and the risk of an accident.
Autumn leaves usually disappear with the first snow, and few people remember that their remains can remain hidden where they are not exactly welcome. The outdoor unit is exposed to wind, moisture and small dirt all year round. But if leaves, needles or twigs pile up around it, it can have a bigger impact than it might seem at first glance.
Why leaves the heat pump loads
The outdoor unit needs enough free space for proper air circulation. As soon as the slats or the lower part start to become clogged with leaves, the flow is restricted and the device has to work more intensively. The result is higher electricity consumption and more wear and tear on key components.
And in winter, the problem is even more pronounced. The leaves trap moisture, which can freeze and form ice deposits during frosts. These then not only reduce the efficiency of the exchanger, but can also damage the delicate lamellae, which are essential for proper heat transfer.
Another risk is the gradual decomposition of organic residues. Damp leaves can accelerate the corrosion of metal parts and become a breeding ground for mold. So even though the pump seems to be still heating, its life is subtly shortened.
How to handle the inspection yourself
At the same time, the January inspection is neither complicated nor time-consuming. Just turn off the unit first and visually check its surroundings. Remove leaves from the top, sides and area under the unit by hand or with a soft broom.
If dirt is trapped between the slats, a gentle stream of water or air will help. But avoid high pressure that could bend them.
The area around the unit is part of prevention. Bushes and branches should not reach close to it, and the space around it should remain freely accessible throughout the year. Regular cleaning of the garden basically helps not only aesthetics, but also technology.
Small control with big effect
Spending a few minutes on the outdoor unit in January is definitely worth it. A clean heat pump heats more economically, more quietly and without unnecessary performance fluctuations. Regular maintenance will also reduce the risk of breakdown at the most inopportune moment, when you depend on the heating every day.
Regular care does not mean such a complicated service, but a little attention and common sense. And just the leaves, which seem to be something so banal, can decide how reliably it will serve you throughout the winter.
