Discover the Advantages of Adjusting Boiler Flow Temperature

When it comes to home heating, finding the right boiler temperature setting is essential for both comfort and efficiency. A boiler that is set at the ideal temperature not only ensures a warm and cosy living space but also helps in saving money by optimizing energy consumption.

Some combi boilers operate inefficiently leading to higher gas bills for households and increased carbon emissions. Lowering the heating operating temperature can enhance your boiler’s efficiency without compromising your property comfort. We assist you in determining if your boiler is suitable for this adjustment and guide you through the process of making this straightforward change.

In this article, we will explore the importance of setting the correct flow temperature for your boiler, the types of boilers available, and how to adjust the temperature settings to get maximum efficiency.

Lowering your Flow Temperature to Save Money

One of the most effective ways to save money on your heating bills is by lowering your boiler’s flow temperature. The flow temperature refers to the temperature of the water leaving the boiler and circulating through your home’s heating system. By reducing this flow water temperature, you can significantly decrease energy consumption and, consequently, your utility costs.

What temperature should a boiler be set at?

The ideal flow temperature setting varies depending on the type of heating system you have and the climate in your region. In general, a flow temperature setting of 60-70°C (140-158°F) is considered suitable for most homes during the colder months. However, between May-September, you will be able to set a lower flow temperature or even lower.

What type of boiler do I need?

There are several types of boilers available, each offering different heating needs. The most common ones are combi boilers but there are system boilers and regular boilers. Combi boilers are popular for their space-saving design and efficiency, as they heat water on demand. System boilers are more suitable for homes with multiple bathrooms, while regular boilers are often found in older properties with traditional systems. Regular boilers are used on properties where the water pressure is low.

How to Change Your Boiler’s Flow Temperature

Adjusting your boiler’s flow temperature can be a straightforward process. Most modern boilers come with digital displays or dials that allow you to change the maximum temperature and settings easily. It’s crucial to read your boiler’s user manual to understand the specific steps for your model. By reducing the boiler flow settings of the hot water cylinder by just a few degrees, you can make a significant impact on your heating costs without compromising on comfort.

If you have a smart heating control system, you can easily adjust the temperature using a smart device. Alternatively, if you don’t have smart controls, you can manually turn the knobs on the boiler to change any settings.

What is the correct condensing boiler temperature setting?

If you have a new condensing boiler, it’s essential to set the flow temperature correctly to take full advantage of its efficiency. Condensing boilers are designed to extract as much heat as possible from the flue gases, But this process works best and most efficiently when the flow temperature is low, usually between 50 and 60°C (when condensation happens).

Setting it any higher would lead to overflow temperatures, decreased efficiency and wasted energy.

Our three top tips for a home heating system

    1. Lower your temperature: reducing your flow temperature can lead to savings of up to £500/ year. Experiment with different settings until you find the sweet spot that keeps your home warm without unnecessary energy usage.
  • Bedrooms don’t need as much heating: If your home has zone heating capabilities, consider reducing the temperature in the bedrooms during the day when they’re not in use. This way, you can focus the heat where it’s needed the most.
  • Will I notice any changes in my heating system? You might be wondering if lowering the flow temperature will affect the performance of your heating system. Rest assured, you’re unlikely to notice any difference in the warmth of your home. Modern boilers are designed to adjust and maintain the desired temperature regardless of the settings.

Boiler Dials and Digital Displays

Your boiler’s dials and digital displays can provide valuable information about your boiler controls its performance. Keep an eye on the pressure (which has to be 1 bar), flow temperature, and any error codes that might indicate a potential issue. Regularly checking these displays will help you identify and resolve problems promptly, ensuring your boiler operates efficiently.

Setting your thermostatic radiator valves

Thermostatic radiator valves (TRVs) allow you to control the temperature in individual rooms. By adjusting the TRVs, you can customize the central heating in different spaces, saving energy in areas that don’t require as much warmth. It’s a convenient way to maximize comfort and minimize expenses. We also install smart radiator thermostats which help to control your central heating systems even easier.

What is the recommended temperature setting for the hot water on my combi boiler?

Combi boilers are known for optimum efficiency and their ability to provide hot water on demand. For optimal efficiency, the flow temperature for hot water gas boilers should be around 50°C (122°F). This temperature ensures that you have enough hot water and central heating without wasting energy at excessively high temperatures.

Advice with our Efficiency

When it comes to improving your boiler central heating part’s efficiency, seeking professional advice can be valuable. Our gas engineer can assess your heating system, provide personalized recommendations, and perform any necessary maintenance to keep your boiler running smoothly. We can install a new smart room thermostat, thermostats, and weather compensation. We can also help you to calculate your property heat demand and design a better-performing central heating system.

Setting the thermostat temperature at the ideal flow temperature for your boiler is crucial for both comfort and cost savings. Adjusting the temperature to suit your system needs and taking advantage of modern technology, you can create a warm and inviting living space while keeping your energy consumption and bills in check.

Are you considering installing an air-source heat pump?

If your system can operate at a flow temperature of 45°C or lower, then it should work seamlessly with a heat pump without requiring any modifications. The perfect system for heat pumps is underfloor heating (UFH) because these are operating at lower temperatures. Older homes that have undergone extensive insulation improvements are also very good.

However, it’s essential to be aware that some older homes might have ‘microbore’ pipework instead of the standard 15mm pipework. In such cases, the pipework diameter is smaller, often 10mm or even 8mm, and these smaller pipes are not suitable for use with heat pumps. It’s crucial to check the suitability of your pipework before considering the installation.
