Not sure if your electrical system can withstand the addition of a new device?
The right size of the main circuit breaker is a prerequisite for worry-free electricity consumption. With an electrical test, you can get a quick and affordable digital consultation without having to call an electrician and answer to the question of whether your current main circuit breaker is of the right size or should you consider replacing it.
Prior testing helps to prevent a situation where the installation of a heat pump reveals that the simultaneous operation of large electrical equipment knocks out the circuit breaker.
Frequently Asked Questions
The outdoor unit of an air source heat pump draws heat energy from the outside air and uses refrigerant to pump it into the indoor unit located inside the building. The indoor unit then conducts heat to the room by means of a fan.
An air source heat pump is considered as auxiliary heating and is best suited for homes with an already existing main heat source. If the outdoor temperature drops too low, the main heat source can support the air source heat pump.
At the same time, modern air source heat pumps are very efficient and reliable even in cold weather. Some devices operate even at temperatures down to -35 °C. Most air source heat pump models can be used as long as the outdoor temperature falls down to -10 °C to -25 °C.
Depending on the specifics and location, the installation of an air source heat pump takes 3-5 hours, more complex objects may take 1-2 days with preparatory work.
If the device is regularly maintained, properly used and taken care of, the service life of a high-quality heat pump will be 10-15 years or even more.
Often, new and much more economical technology becomes available in ten years. Although your old device may still work, it may no longer be economically viable to use it.
By choosing our full-service rental of air source heat pumps, you can be sure that you will always keep up with the latest technology – we will replace your air conditioner every five years at no extra cost!
For efficient operation and a long lifespan, air source heat pumps require filter cleaning at least once a month and technical inspection once a year.
Cleaning the filter is easy and only takes a few minutes. The easiest way is to do it with a small vacuum cleaner nozzle. Your heat pump installer or maintainer can show you how it's done. Tutorial videos are also available online.
Yes, but first you should make sure that the service provider is a contractual partner of Eesti Energia. Otherwise, the device will lose its five-year warranty.
Depending on the heat pump and its type, it is possible to save up to 80% on heating costs (compared to electric heating). The amount of savings depends on the type of heating currently used, the insulation of the house, the layout, the desired temperature.
In winter, it is 2-3 times cheaper to heat with an air source heat pump than with electricity, but in the spring-autumn period, it is more than five times cheaper.
Timely maintenance and cleaning of the dust filters at least once a month help to maintain the optimal energy consumption of your air source heat pump.
If the operation of your air source heat pump can be monitored from an app, it is advisable to do so, as each raised degree of heat can increase electricity consumption by 5-10%.
For example, in order to produce 5 kWh of heat, an average heat pump consumes only 1 kWh of electricity and the remaining 4 kWh is free heat received from the air.
It is difficult to give a single answer, as air conditioners and their manufacturers are different. This information is always available in the user guide.
If a layer of ice has formed on the outdoor unit of an air source heat pump due to high humidity, the reverse process starts. The device draws heat from indoors to defrost the heat exchanger of the outdoor unit. That is why cooler air enters the interior.

How does an air-to-air heat pump solution work?
Air-to-air heat pump technology allows thermal energy to be pumped from one environment to another.
An air-to-air heat pump consists of two units: outdoor and indoor.

Outdoor unit
Is installed outdoors to open air. The device can thus take thermal energy from the outside air and pump it into the indoor unit inside the building using a special refrigerant.
Indoor unit
Is mounted on the wall inside the room and directs the heat stored in the refrigerant to the room using a fan. The indoor unit is installed under the ceiling, but not higher than 2.5 metres from the floor.
Heat pumps can also work the other way around, cooling rooms in summer. During cooling, thermal energy is pumped from indoors to the outdoor environment.
About air-to-air heat pump installation
All air-to-air heat pumps are sold together with installation. The price of the installation depends on the features of the site. For a more accurate calculation, choose the appropriate installation method for your home.
An air-to-air heat pump requires the installation of an outdoor and an indoor unit.

Outdoor unit
Is installed outdoors to open air. The device can thus take thermal energy from the outside air and pump it into the indoor unit inside the building using a special refrigerant.
Indoor unit
Is mounted on the wall inside the room and directs the heat stored in the refrigerant to the room using a fan. The indoor unit is installed under the ceiling, but not higher than 2.5 metres from the floor.
In the standard installation of an air-to-air heat pump, the distance between the indoor and outdoor unit is considered to be up to 5 m.
The farther the distance between the devices, the more expensive the installation, because the piping with the hubcap has to be extended and additional gas has to be added.
When measuring the distance, it must be taken into account that the pipes are routed from the wall or ceiling, and the distance must be measured along the walls and not directly over the air. The maximum distance between the indoor and outdoor unit should be up to 15 metres.
