Only certified professionals can install and dismantle heat pumps. On 1 September 2013, it became a legal requirement to be F-gas certified to install and dismantle air-to-air heat pumps. The first thing to do when installing a heat pump is therefore to make sure that the installer is certified to work with products containing HFC gases. Remember to ask to see proof of certification before accepting the offer.

There are wall, ceiling and floor models. The most common type is a wall-mounted heat pump, but a floor model can be smart if you don't want to have the heat pump high on the wall. A wall-mounted indoor unit should be mounted high up on the wall. If there are wooden floors in the home and a wall-mounted model is too low, the floor can dry out. There are also some models with several indoor units connected to one outdoor unit. These are often referred to as multi-splits.

A ceiling-mounted or ceiling cassette is mounted on the ceiling and provides an even distribution of heating or cooling in the room. These are also discreet and integrate well with the ceiling. Ceiling cassette or ceiling-mounted heat pumps can be installed in different types of rooms, they are particularly suitable for larger rooms or open floor plans where the air needs to be distributed evenly.

The indoor unit of air-to-air heat pumps should be placed close to where you spend most of your time. The heat pump is a point source of heating and the heat is best distributed in homes with an open-plan layout. For example, you can place the indoor unit in a large hallway and control the air circulation towards the living room.

It's not a problem to have some distance between the outdoor and indoor parts of the heat pump, but it's important to think about where the pipework between the two parts should go. They must be laid so that they are not damaged and at risk of being torn out. The pipe section should be at least two metres long and no more than twenty.

The outdoor unit generates some vibration noise and should preferably not be attached to the building's cladding, but placed on a ground support or attached to the foundation wall. It is also important that vibration dampers are fitted. Mount the outdoor unit on a smooth and solid surface that allows proper drainage of condensation water. This can help prevent water damage and maintain the heat pump's performance.

There will be some noise from the heat pump's indoor and outdoor units. In principle, this will not be annoying if you find an appropriate location. For example, you should avoid placing the heat pump's outdoor unit close to the bedroom window or next to a neighbour's home.

It is an advantage to shield the outdoor unit from precipitation and wind with, for example, a small roof or a properly designed heat pump housing, this can extend the lifetime of the outdoor unit and protect it from damage caused by the outdoor environment. It is also important that the outdoor unit is not mounted too low. In winter, condensation from the heat pump's outdoor unit will drip onto the ground and freeze. If the distance from the ground is not great enough, the ice mould can quickly grow up into the machine and damage it.

If you want to minimise noise, you should choose a model with the lowest possible sound level. Some models have noise-cancelling features that help to reduce the noise level even further; this is measured in decibels (DB) and is usually stated in the product specifications.

Yes, it is usually necessary to drill a hole through the wall to install a heat pump. This hole is used to run pipes and cables between the outdoor unit and the indoor unit of the heat pump.

The hole that is drilled must be large enough to allow all necessary components to fit through and be accurately positioned to ensure a correct connection between the indoor unit and the outdoor unit. It is important to have professional installation to ensure that the hole is drilled in the right place and of the right size, and that all connections are made correctly.

Once the hole has been drilled, it will be insulated to prevent draughts and prevent energy loss. It is important to follow the manufacturer's recommendations and local building regulations when installing heat pumps to ensure a safe and efficient installation. The installer will have the right equipment and knowledge to drill the hole safely and efficiently, while taking into account any structural or aesthetic considerations.

To best care for your heat pump, it is important that you keep it clean and free of dust, simple cleaning should be done once or twice a month. Vacuuming or rinsing the filters, wiping dust off surfaces and behind the air dampers is enough.

Keep the outdoor unit free of leaves, snow, branches etc. so that the surrounding area is open to ensure optimum air circulation. You can wipe the cover with a damp cloth.

Routine maintenance and servicing are crucial factors for your heat pump to function optimally. We recommend a service by your local dealer every two years.

More and more people want to choose a more sustainable alternative when choosing heating or cooling.

A heat pump is good for both the climate of our planet and for your indoor climate as they can cut our energy consumption significantly. Heating systems are one of the areas that contribute to a more sustainable future as they contribute to a reduced emission of greenhouse gases compared to other heating systems.

Yes, a heat pump in your holiday home can be a smart investment for both electricity costs and the indoor climate. Holiday homes are often located in areas that make them vulnerable to wear and tear from harsh weather conditions. Moisture damage is not uncommon and can lead to major unforeseen costs. Allowing the heat pump to work steadily at around 5-10 degrees when the cabin is not in use helps to prevent moisture damage, frozen pipes and the building will stay in much better condition. The cost of allowing the heat pump to operate at low temperatures is minimal, minimising the chance of major repair costs.

Whether it's cold or warm outside, a heat pump in your cabin offers many benefits and provides an excellent indoor climate. Enjoy a cool and comfortable temperature inside on the hottest days by using it as air conditioning, or warm up your cabin before you arrive on a cold winter day by setting the desired temperature from your smartphone.

Moisture in the heat pump can be a problem that can occur for various reasons and can affect the performance and reliability of the unit. Here are some common causes of moisture in heat pumps and how you can deal with it:

• Condensation: Condensation can form on the heat pump's inner part when it cools the air in the room. This is normal, especially during the cooling season, but it can cause moisture to drip or collect around the unit. Good ventilation in the room can help to reduce condensation.
• Drainage problems: If the heat pump's drainage system is not working properly, for example if the drainage pipe is blocked or clogged, it can lead to a build-up of moisture around the unit. Make sure the drainage system is clean and free of obstructions and that water can be drained properly.
• Leakage: If there are leaks in the heat pump's pipes or connections, it can cause moisture to leak into the unit. It is important to regularly check for leaks and have them repaired as soon as possible to prevent damage to the unit.
• Incorrect insulation: Insufficient insulation around the heat pump's pipes or connections can allow moisture to enter the unit. Make sure all pipes and connections are properly insulated to prevent condensation and leaks.
• High humidity in the room: If the humidity in the room is too high, it can cause moisture to accumulate around the heat pump. The use of dehumidifiers or ventilation systems can help to reduce the humidity in the room.

If you experience moisture in your heat pump, you should inspect the unit thoroughly to identify the cause and take the necessary steps to resolve the issue. If you are unsure how to deal with moisture issues, it is best to contact a qualified technician or installer for assistance.

Yes, an air-to-air heat pump can also be used as air conditioning. The difference between regular air conditioning and a heat pump as air conditioning is the air they emit. A conventional air conditioning unit will produce cold air based on the air that is already inside the home, while an air conditioning heat pump will produce cold air based on the outside air. This provides a continuous supply of fresh air.

If you're thinking about financial benefits, you can't ignore the versatility of a heat pump. Cool and cool in summer - warm and cosy in winter.
