Air source heat pumps for detached homes

Warm in winter, cool in summer — correctly sized for your home.

Floor area alone does not determine the right unit for a detached home. The floor plan, number of storeys, insulation and intended use determine whether one or two units are needed. We assess the right solution and install it throughout Helsinki, Espoo and Vantaa.

What determines the right air source heat pump for a detached home?

There is no single model or number of units that suits every home. The right solution depends on how warm and cool air can move through your particular floor plan.

Floor plan

Air circulates more easily in an open-plan space. Closed rooms and long corridors can limit the area served by one indoor unit.

Storeys

In a two-storey home, one unit may not serve both floors evenly. Two units or a multi-split system may be the better solution.

Heating system

An air source heat pump usually works alongside the existing heating system, which affects sizing and how the unit is used.

How the unit will be used

Heating-focused use and cooling-only use require different output, placement and airflow choices.

Air source heat pumps for heating and cooling detached homes

Choose the main use first. Heating-focused use requires strong cold-weather output and good heat distribution, while cooling depends on the rooms that need cool air. Final sizing is always based on the floor plan and your needs.

One or two air source heat pumps?

One correctly placed unit may serve a large open-plan, single-storey home. A two-storey or closed floor plan may need two units or a multi-split system. The decision should be based on airflow and intended use, not only floor area.

Frequently asked questions about air source heat pumps for detached homes

Is one air source heat pump enough for a detached home?

One unit may be enough for an open-plan, single-storey home when air can circulate from a central space. A closed floor plan, several storeys or separate living zones may call for two units or a multi-split system.

What is the best air source heat pump for a detached home?

The best model is correctly sized for the home and intended use. In addition to floor area, the floor plan, insulation, existing heating system, number of storeys, placement and the balance between heating and cooling all matter.

How much does an installed air source heat pump cost for a detached home?

The total price consists of the selected unit, the €749 standard installation and any site-specific additional work. Penetrations through concrete or masonry walls, special brackets and other exceptions are priced after the assessment.

Where should the indoor unit be installed?

The indoor unit should be placed where airflow can reach the desired rooms with as few obstructions as possible. A central open space often works better than a side room, but the final location depends on the floor plan and intended use.

Can an air source heat pump be the only heating system in a detached home?

In a detached home, an air source heat pump normally works alongside another heating system. It can reduce the need for primary heating, but reliable backup heating should be retained for the coldest weather and exceptional situations.
