To achieve the best possible indoor comfort for workers, guests, patients or other users, every building is equipped with a suitable Heating and/or comfort cooling system. There are various options to increase or decrease the room temperatures and how this is controlled:
Among others, cover fan coil units, cooling panels and climate ceilings. These are mostly installed in the ceiling and provide a room with heating and/or cooling via a 2-, 3- or 4-pipe system. To control the room temperature, the most accurate results, in both full- and partial load conditions, can be achieved by using Pressure-Independent balancing and Control Valves (PICV). They are simply set to the required flow under full load conditions and function as automatic flow limiters. In partial load conditions, the actuator accurately reduces the flow according to needs. No overflow situation will occur, increasing the energy efficiency of the heat or cooling source.The actuators can be controlled via a Building Management System (BMS) or stand-alone electronic room controllers. In case the terminal units contain a fan, the room controller can also be used to change the fan speed.
In most cases, designed as a 2-pipe system with one or more radiators in every room. To control the room temperature, Danfoss radiator thermostats are used. They consist of a thermostatic radiator valve, mostly with a pre-setting of the design flow, and a temperature sensor. A wide variety of sensors ensure accurate control of the room temperature. For example, if curtains prevent proper measurement of room temperature, a version with remote sensor or remote sensor and control provide a better solution.For optimal space comfort, it is recommended to equip the radiator system with an automatic hydronic balancing solution. This eliminates pressure fluctuations, thereby ensuring that the radiator thermostats function optimally.
Offers a high level of comfort by heating rooms from the floor up. The heat is spread evenly and, because it is situated in the floor, it doesn't take up any precious room space. We offer both water-based (hydronic) underfloor heating as well as electric underfloor heating solutions. It can be used to heat all spaces in the building or to only heat dedicated spaces, such as hotel bathrooms, where the comfort requirements are highest.With both hydronic underfloor heating and electric underfloor heating systems, the room and/or floor temperature can be controlled via room thermostats. These ensure a superb level of space comfort while avoiding rooms being heated when this is not needed.Electric Heating by Danfoss is energy efficient and environmentally friendly. It's a flexible solution for new build and renovation that can be used for wet and dry installation. Quick responding heating systems are easy to control. They enable you great comfort and convenience whilst ensuring user friendly solutions with lasting effect and highest quality standards.

AB-QM Pressure Independent balancing and Control Valves (PICV) provide both a control functionality and dynamic balancing solution for HVAC heating and cooling systems. PICVs are designed for various types of terminal units, Air Handling Units (AHU), chillers and provide high indoor comfort and energy efficiency in public and commercial buildings.
To take advantage of the combined balancing and control features of Danfoss AB-QM it has to be equipped with actuators controlled by room thermostats or a Building Management System. Danfoss offers a broad range of actuators varying from thermal on-off to digital step motor actuators with bus communication.
Robustly built and designed to meet the rigors of the commercial and industrial sectors, a comprehensive range of Danfoss radiator valves is available for practically all systems and installation conditions.
Danfoss Dynamic valve™, the innovative 2-in-1 pressure independent radiator valve that ensures both optimal temperature control as well as creating automatic hydronic balance in two-pipe heating systems – all in a single valve.
Danfoss radiator thermostats maintain constant desired room temperatures, individually room by room and help to reduce energy consumption. Mechanical thermostats or smartphone controlled thermostats - find them all here.
Danfoss floor heating mixing shunts establish a water temperature low enough to safely be distributed through the floor heating system. It’s designed to fit the FH manifolds and mixes the warm supply temperature with colder floor heating return flow to the required floor heating supply temperature.
Danfoss floor heating manifolds are characterized by their flexibility to establish the best suited manifold solution based on requirements. Select from all the components to construct a manifold with or without pre-setting, flow-meters, shut-off valves and air-vents that best fits your project.
To ensure hydronic (water based) underfloor heating or cooling systems achieve the expected high level of comfort and low energy consumption, good room temperature controls are essential. They control the room or floor temperature to avoid overheating. For optimal comfort each room has it's own room thermostat.
Digital controllers have the unique features allowing you to reduce energy waste. Some thermostats are fitted with Wi-Fi allowing remote control of heating systems via mobile application.
Analogue thermostats are electronic control units allowing setting the heating system type and adjustment of control parameters.
The heating mats are used for installation in a thin layer of tile adhesive, self-leveling mixture, or similar. The standard minimum thickness of the floor layer is 5-8 mm while the thickness of electric heating mat is 3–4.5 mm. This minimizes the floor level increase. Electric heating mats consist of a thin cable securely fixed on self-adhesive glass-fiber mesh, usually of 50 cm width. Thin heating mats are manufactured as ready-made heating sections with a specific area (i.e. 0.5, 1, 1.5 … 12 m²) including a power supply cable (cold lead) and hermetically sealed connections.
The self-limiting heating cables for indoors are used for maintenance of the hot water supply and other fluids that need to maintain a certain temperature. The self-limiting capability of the cable ensures that the output increases or decreases according to the surrounding temperature. It ensures hot water in all taps, providing savings compared to a circulatory hot water system.
Heating cables are used for a variety of applications, including indoor comfort floor heating and total heating both for small houses as well as large commercial buildings. Heating cables are mostly used in connection with new building or larger renovation projects.

Too warm, too cold, and no chance to regulate the heating inside the individual apartments—those were the issues facing the residents in a 9-storey apartment building in Tallinn, Estonia. By upgrading the existing one-pipe system into a two-pipe system with automatic hydronic balancing, the residents now enjoy improved comfort and 25 percent savings on the energy bill.
Energy efficiency and indoor comfort are top of mind among building owners today. In Sweden, the housing association Bostadsbolaget AB in Mjölby took action when they were confronted with a rising energy bill due to insufficient heat distribution in a 10-storey residential building.
