Pump control
The average temperature for central heating systems in Dutch homes is between 70-90°C. However, these temperatures are too high for effective underfloor heating. For an underfloor heating system to function properly, the water temperature should only be around
40°C . The
pump control of an underfloor heating system regulates the flow of hot water through the pipes under the floor. The pump is usually switched on and off by a thermostat, which measures the air temperature and activates the pump when it falls below a certain point. It can also be set to different speeds, depending on the room's heating needs—for example, a living room might need more heat than a bedroom. The pump speed can also be adjusted manually if necessary.
Pump controller
A
pump controller is a device that regulates the speed of a pump. The pump can be set to different
speeds , depending on the room's heating needs, and can also be manually adjusted if necessary. The pump controller monitors the water
temperature in the pipes and adjusts it accordingly. This ensures that the underfloor heating system operates
efficiently and that no energy or hot water is wasted. Furthermore, the pump controller helps maintain a comfortable environment and reduce
energy costs .
Underfloor heating pump
The
underfloor heating pump is a key component of an
underfloor heating system. It circulates hot water through the pipes under the floor, helping to warm the room. The pump is usually switched on and off by a thermostat, which measures the air temperature and activates the pump when it falls below a certain point. The underfloor heating pump also helps regulate the pressure in the pipes, preventing them from clogging and reducing the risk of leaks. The pump is usually located near the boiler, allowing it to receive
hot water directly from the boiler without having to wait for it to circulate through the rest of the system.
Pump switch
In most homes with underfloor heating, the underfloor heating pump is a major energy source. Even older pumps consume a significant amount of energy. These pumps often run 24/7, 365 days a year. So even when heat isn't needed, the pump continues to consume unnecessary energy. The
pump switch saves you
energy costs by only turning on the underfloor heating circulation pump when the central heating water temperature exceeds the
set temperature and turning it off again when it falls below. This way, your pump doesn't have to run unnecessarily for hours every day.
RTL valve
An
RTL valve , also called a
return valve , is ideal for underfloor heating in small spaces such as bathrooms or kitchens that will be used in conjunction with conventional radiators. The RTL valve uses a
sensor in the
return pipe to detect the water temperature in the heating pipes. The set temperature determines when the valve opens to let in cold water, which then begins to heat the floor. The return water must reach the
set temperature before the valve closes again. Because an RTL valve functions as an automatic temperature controller, you can install it in small spaces, up to 25 meters of heating pipe, without a manifold.
Bypass
When installing an underfloor heating system, it's important to consider whether or not to install
a pressure relief valve (also called
a bypass ). A bypass
protects your
pipes by preventing excessive pressure buildup. When demand is low because thermostatic radiator valves are turned off, a
pressure difference can occur between the supply and return pipes. A
spring-loaded bypass protects your pipes if the pressure in one of them becomes too high.
