Exact temperature regulation achieves the right temperature at the right time in each room. This involves factors such as residents, sun, inside thermal gains, sluggishness of a system, etc. Ideally each room would have its own heating circuit. The basic types of controls for a heating system are electric and hydraulic.

Regulating heat productions

We distinguish thermostat controls and controls based on outside temperature to regulate furnace water temperature.

• Thermostat controls can turn off the furnace as soon as the set temperature is achieved.
• For outside controls, the correct location of the outside and inside sensors is essential.
• Caution in both cases: Adhere to minimum furnace run time according to the manufacturer. Imprecise regulation increases energy consumption.

Control of heat distribution and heat radiation

• Room thermostat regulation: a thermostat or temperature sensor is installed in a reference room.
• In selecting the reference room, consider the sun’s radiation and other heat sources.
• If the reference room has an additional heat source such as a tile stove, then this room temperature influence on the thermostat should be adjustable.
• The location of the thermostat also influences how it works; it should not be installed in locations exposed to cold or sunlight.
• Installation height: ca. 1.5 m
• Outside temperature controls regulate the temperature of inlet water according to a heating curve based on outside temperature.

Temperature reduction

A reduction in temperature at night or at times of reduced need lets you save additional energy. Especially for poorly insulated houses, this enables significant energy savings.

Radiator thermostat valves

• They regulate heat radiation by controlling the water throughput.
• Should be used in combination with other control systems.
• For existing heating systems, ensure that the hydraulic design of the overall heating system is suitable for the use of thermostat valves.
• Correct location of the temperature sensor is particularly important, so that air can move past it without restriction (not hindered by curtains, etc.).
• Different control and regulation systems must be tuned to one another.
