How to Look After Your Heat Pump

A heat pump is an efficient piece of kit, but like any piece of equipment, it needs a bit of care to perform its best. Proper maintenance can help extend the life of your heat pump, keep it running efficiently, and prevent costly repairs. Neglecting maintenance can lead to reduced efficiency, higher energy bills, and even breakdowns.

By staying on top of regular checks, cleaning, and servicing, you ensure your heat pump continues to provide reliable heating and hot water throughout the year.

Regular Maintenance Tasks You Can Do

While some aspects of heat pump maintenance should be left to professionals, there are a few simple tasks you can do yourself to keep your system in good condition.

1. Clear any debris

The outdoor unit is exposed to the elements and can get clogged with dirt, leaves, and debris. Keeping the area around the unit clean will help maintain good air flow which is essential for keeping your home warm.

2. Give it a clean

Just like anything outside the unit will occasionally need a bit of a clean. Just use warm water and a soft cloth to wipe off any grime build up.

3. Check for ice:

During colder months, check for ice buildup on the outdoor unit. If there’s excessive ice, it could affect the system’s efficiency and might signal a problem with the defrost cycle.

4. Check for obstructions

Heat pumps need good air flow both behind and in front of the unit. Avoid placing anything, like an outside sofa or chair, in front of the unit and check for build up of debris or weeds behind and to the side of the unit.

Annual Professional Servicing

Whilst you can carry out the three tasks above yourself, it’s important to schedule a professional service once a year to ensure your heat pump remains in peak condition. It’s also a requirement to maintain your manufacturers warranty. A heating engineer will inspect, clean, and tune your system, identifying any potential problems before they turn into costly repairs.

What Does Professional Servicing Include?

During an annual service, a heating engineer will:

• Inspect the refrigerant levels: Proper refrigerant levels are crucial for your heat pump’s efficiency. Low refrigerant can indicate a leak, which needs to be fixed.
• Check the electrical connections: Faulty wiring can lead to inefficient operation or even damage to your system.
• Inspect and clean the fan blades: Clean fan blades help maintain proper airflow and efficiency.
• Inspect and clean the evaporator: this is where most of the magic happens to extract heat in the air and transfer it to your home.
• Check the defrost cycle: If your heat pump has a defrost mode, the technician will make sure it’s functioning properly to prevent ice buildup during winter.
• Check and clean the magnetic filter and strainer: these capture dirt and debris that circulates through your central heating pipes. If you have a modern boiler you’ll also have a filter on this.

Signs Your Heat Pump Needs Attention

If your heat pump starts acting up, there are a few signs that you may need to call in a professional for repairs. Addressing these issues early can prevent larger problems down the road.

• Strange noises: Unusual sounds like rattling, grinding, or squealing could indicate loose parts or issues with how level your heat pump unit is outside. If it is not level it will be harder for the fan to turn evenly.
• Reduced efficiency: If you notice higher energy bills or that your heat pump isn’t heating as well as before, it may need servicing.
• Unusual smells: Musty or burning smells coming from your heat pump could indicate a problem. Switch the unit off and call a heating engineer.

FAQs About Looking After Your Heat Pump

Do I need to cover the outdoor unit in winter?

No, the unit shouldn’t be covered as it will reduce or stop air flow - resulting in no heating or hot water!

How long does a heat pump last with proper maintenance?

With regular maintenance, a heat pump can last anywhere from 15 to 20 years. Annual servicing by a professional helps extend the system’s lifespan and ensures it runs efficiently.

What should I do if my heat pump has ice on it?

If you notice excessive ice buildup on the outdoor unit, check that the system’s defrost cycle is working. If the ice persists, turn off the heat pump and call an engineer for help.

Can I service a heat pump myself?

While you can perform basic tasks like cleaning away debris, professional servicing should be done annually to address more complex issues like refrigerant levels and electrical components.
