Best Settings for your Worcester combi boiler

Combination boilers are the most popular type of boilers within the UK, providing both a source of heating and hot water within a property, whilst also saving space as there is no need for a water tank.

In addition, Worcester Bosch combi-boilers are also a very popular brand due to the manufacturer being long-established and well known for producing top-quality boilers. Therefore, in this guide, we are going to cover the most appropriate settings to heat your property and the hot water effectively and efficiently.

Why choose a Worcester Bosch Boiler?

Let’s quickly cover why Worcester Bosch Boilers are one of the most popular brands of boilers within the UK. As we have briefly mentioned, the brand is very well known and respected for producing high-quality boilers across a wide range of boiler types.

In addition, to the boilers themselves, the manufacturer also offers a high level of aftercare to their customers, including offering long warranties which is also a popular factor.

How does a Combi-Boiler Work?

Combi-boilers are highly efficient, yet compact boilers that heat water directly from the mains, on-demand and only as and when needed. A combi-boiler will ignite when the hot water tap within the property is turned on, or when the heating is programmed to start up.

With a combi-boiler, there is no need for a water tank which not only saves space within the property but also improves the efficiency as there is no requirement to heat up and maintain the temperature of a large quantity of water. Modern Combi-boilers have been developed to be very efficient devices, providing up to 92% efficiency ratings to consumers, minimising wasted energy by the boiler unit.

What Are the Typical Control Settings on a Worcester Bosch Combi-Boiler?

Modern Worcester Bosch combi-boilers will have a control panel enabling the homeowner or resident to control the system using a 24-hour clock, providing around the clock control of both the radiators and hot water system. There are some subtle differences between boiler models and therefore in order to set or change the control programme on your Worcester Bosch combi-boiler, please refer to the boiler’s manual.

The ideal temperature to set the thermostat to will vary depending on the property itself, its location and any other factors such as insulation measures installed.

As a guide, during the colder months, the optimum temperature to set the heating system would be between 18 and 21 degrees. In an extreme cold spell, or in more northern locations, this ideal temperature setting may need to increase to between 21 and 23 degrees.

However, if the property itself is well insulated with additional measures such as loft insulation, cavity wall insulation or draught-proofing, then you may be able to experiment with a lower temperature setting, such as 17 degrees.

It is worth undertaking some trial and error to find the most suitable temperature setting for your boiler and property, whilst also remembering that even lowering the thermostat by 1 degree can save energy and therefore reduce your household energy bills.

Meanwhile, for the hot water side of the programming, the ideal settings are anywhere between 55 and 60 degrees in order to provide sufficient heat, protect by removing any bacteria within the water and protect the young or elderly from the risk of scolding.

What Smart Devices are Compatible with a Worcester Bosch Combi-Boiler?

These days there are many different smart devices available on the market that have been developed to revolutionise how energy is controlled within the home, offering different types of benefits such as:

  • Remotely controlling the boiler settings for heating and hot water
  • Allow shared access to the boiler settings from multiple devices
  • To track the performance of the boiler and trends of the household requirements
  • To create zones within the property to control the heating in different areas

Most devices use technology to provide the benefits above, usually by a requirement for a device within the property and an app on a smartphone to wirelessly monitor and control from anywhere.

Such devices provide two main advantages: the ease of changing the boiler settings as well as potentially improving the energy efficiency of the household.

For example, if you were running late at work, you can remotely delay the programmed heating settings, therefore, stopping the heating from operating while the property is empty.

The market for such smart devices expands regularly with new manufactures of such technology entering the market. Therefore, once you have whittled down the type of smart device you would like, it is worth checking the compatibility for a Worcester Bosch boiler.

Should you wish to choose a Worchester Bosch developed product, there is the Bosch EasyControl smart thermostat available directly from Worchester Bosch providing smart technology and remote controls.

This award-winning product can be fitted to a range of heating systems to provide a high-tech solution to controlling the system remotely, detecting the presence in order to adjust the heating requirements and enabling individual room control.

The device itself is modern and attractive, simple to operate and comes with a 12-year guarantee. For further details on this product please check out EasyControl on the Worchester Bosch website.

What Other Ways Can I Save Energy?

In addition to installing smart technology, there is a range of other options to improve a household’s energy usage such as:

• Install Insulation within the Property

There are various types of insulation options available depending on the type of property including loft insulation, underfloor insulation, exterior cladding with insulating properties or cavity wall insulation to name a few. For further advice regarding what might be the best insulation solution for your property, please check out

This website provides independent advice on planning insulation, making your home greener or ways to reduce household energy bills. There is also a section on the website dedicated to financial assistance for installing such measures, providing details on any Government schemes or local funding that may be available to assist with the costs depending on the households’ personal circumstances.

• Regular boiler servicing

A simple way to ensure that your boiler is functioning safely and efficiently is to ensure that the boiler is serviced annually by a professional Gas Safe registered heating engineer.

• Fit the radiators with temperature control valves

If the radiators within a property are not currently fitted with valves, valves can be fitted onto the side of each radiator enabling the option to turn the radiators down low, or off in rooms that are not in constant use. There are two different types of valves; those that are operated manually and those that control the radiator by stopping the water flowing to the radiator once the room has reached the desired temperature.

• Installing Weather Compensators

A weather compensation controller monitors both the internal temperatures and external temperatures and feeds this information back to the boiler so that the settings adjust for the weather. Weather compensators use technology to control the boiler to only operate when needed due to the actual temperature readings rather than simply operating on a programmed timer, therefore saving energy.

Within a modern world where energy resources are becoming more scarce and costly, as well as climate change becoming more focused upon, households are aiming to reduce their energy usage.

Alongside installing a modern, energy-efficient boiler such as a Worcester Bosch Combi-Boiler there is a range of other smart technology devices, insulation and other methods that can enable a property to be as energy-efficient as possible.
