Worcester Bosch Boiler Controls Explained

Using the correct boiler controls can make your life easier, and your boiler more efficient.

Worcester Bosch offers different types of controls for its combi and system boilers. They range from simple-to-operate mechanical timers to more practical digital programmers, room thermostats, and intelligent controls. A combination of modern boiler controls and a magnetic central heating filter can extend your boiler guarantee by 10 years+.

When it comes to Worcester Bosch, there are plenty of options. Unfortunately, this can be confusing if you’re not a boiler expert, luckily that’s exactly what we are. Here’s everything you need to know about Worcester Bosch boiler controls.

Timers and Programmers

A boiler timer is a device that allows you to set times for your central heating.

A programmer allows you to set different times, and temperature for heating and hot water. Note that old or defective boiler controls are a waste of energy and finances.

Room Thermostats

A room thermostat allows you to set the ideal temperature for a room. They are best positioned in the hallway or landing, and fitted away from direct sunlight, clear of curtains or furniture.

Programmable Room Thermostats

Worcester Bosch programmable room stats allow you to set different room temperatures for different times of the day or night. If you set it up correctly, a programmable room thermostat stops the system from heating your home from a ‘cold start’. The control maintains a certain temperature within your home ensuring the boiler only ‘tops up’ the temperature in the home.

Load Compensation

This feature regulates the temperature of the heat reaching the radiators. In case your home is cold, the temperature going to your radiators will be high. But as room temperature increases and less heat is required, this feature will reduce the heat supplied to your radiators. This way, comfort will be maintained and energy use will reduce.

Weather Compensation

This device works by monitoring the weather outside using an outdoor sensor. The control adjusts the temperature of the hot water going to the radiators.

A drop in temperature outside will make the radiators heat up. But if the temperature outside is warmer, the device will instruct the boiler to supply less heat.

This will ensure your home doesn’t use more energy than necessary – boosting your energy efficiency and lowering your energy bills.

Greenstar Sense II – Weather Compensation Controller

The Greenstar Sense II is a practical controller for individuals who demand more from their heating systems. The controller is equipped with a back-lit and touch-sensitive display. It takes advantage of state-of-the-art technology for maximum comfort and savings.

When installed as a room thermostat, this controller provides households with a 4% uplift in energy efficiency. Twin-channel time control gives homeowners command of heating and hot water with six possible settings.

You can access important information about the boiler and heating system from the display. This allows installers and users to review living patterns and tailor the heating system appropriately.
