Why Your Heat Pump Needs Protection from the Elements

Heat pumps are an investment in the long-term energy efficiency and comfort of your home. Whether you have a new installation or an established system, protecting your outdoor heat pump unit is key to maintaining its performance, appearance, and lifespan.

A well-designed cover not only guards against the elements — it also helps your heat pump operate more efficiently by ensuring clear airflow and reducing the strain on working components. The result? Lower running costs, improved efficiency, and fewer breakdowns.

Yet many homeowners leave their units fully exposed — risking corrosion, debris build-up, accidental knocks, and a compromised aesthetic in the garden.

At Marlow Stoves, we help you safeguard your heat pump — with expert advice, a choice of premium-quality covers, and professional fitting where needed.

Why Does Your Heat Pump Need Protection?

Outdoor heat pumps are built to be weather-resistant — but that doesn’t mean they are immune to the effects of constant exposure. Over months and years, even the toughest unit can suffer from:

Protect Your Heat Pump — Why a Cover is Essential

Air source heat pump operating in snowy weather — importance of weather protection for efficiency and lifespan. — Protecting your heat pump from harsh winter weather helps maintain efficiency and extends its lifespan — ask Marlow Stoves about cover options.

Common issues caused by exposure

Harsh weather — rain, snow, ice, and frost all cause moisture buildup, which can lead to corrosion over time
UV exposure — constant sunlight degrades plastics and fades metal finishes
Wind-blown debris — leaves, twigs, pollen, and dust can clog filters and reduce airflow
Animal interference — birds, squirrels, and other wildlife may nest around or inside the unit
Physical damage — accidental knocks from garden equipment, toys, or visitors
Condensation build-up — leading to frozen components or rust

All of these issues can:

Reduce your heat pump’s efficiency
Increase wear and tear on moving parts
Shorten the overall lifespan of your system
Cause higher running costs due to inefficiency
Lead to expensive call-outs and repairs

By installing a properly designed cover, you can avoid these problems — keeping your heat pump running smoothly and quietly all year round.

When’s the Best Time to Install a Heat Pump Cover?

The best time to protect your heat pump is before damage occurs!

Covers can be installed:

At the time of a new heat pump installation
Before autumn and winter weather sets in
Ahead of pollen and debris season in spring
As part of a garden upgrade or landscaping project
When preparing your home for sale

By acting early, you can help ensure years of smooth, trouble-free operation — with the added bonus of improving the look of your garden.

FAQs: Heat Pump Covers & Outdoor Units

Will a cover block airflow or reduce efficiency? No — as long as you use a properly engineered cover (such as those we supply), airflow will remain unrestricted. In fact, protecting your unit from debris and weather helps it to run more efficiently.

Do covers affect the manufacturer’s warranty? The covers we stock are approved and recommended by professional installers and will not affect your heat pump warranty — unlike some cheap or DIY alternatives.

Can a cover help reduce noise? Yes — many of our customers notice a reduction in perceived sound levels after fitting a quality cover. The louvred design helps absorb and deflect sound away from the surrounding area.

Is it worth fitting a cover if my unit is new? Definitely — prevention is far better than cure. Fitting a cover from the start helps maintain the appearance, efficiency, and performance of your new system.

When is the best time to fit a cover? Any time! But ideally before the harsher autumn and winter months — or before pollen and debris season in spring.
