“A well-maintained central heating system offers more than warmth. It brings peace of mind, improved energy performance and long-term value for your property.”
What a Central Heating System Actually Does
A central heating system uses a single heat source, most commonly a boiler, to warm the entire property. Hot water travels through pipework to radiators across different rooms. Once the water cools, it returns to the boiler to be reheated, and the cycle continues.
At Maintracts Services Ltd, we have installed and serviced central heating systems throughout London for many years. With the right system design and proper care, homeowners benefit from steady heat, better efficiency and reduced running costs.
How Heating Systems Work
The Boiler
The boiler is the main source of heat. Whether you use a combi boiler or a system boiler, its job is to heat water using gas. Once warm, the water is pushed through radiators and, in some setups, stored in a cylinder.
Our engineers handle everything from installation to ongoing maintenance, including Vaillant boiler servicing for London homes.
Radiators and Thermostats
Radiators release heat into each room. Thermostats allow you to control how warm your home feels, either centrally or room by room. This makes your heating system more efficient and personalised.
Smart controls have made temperature management even easier. Many households in London now use smart thermostats for better comfort and clearer insight into energy use.
Types of Central Heating Systems Used in UK Homes
There are several heating system types to choose from, each suited to different household needs.
Combi Boilers
A combi boiler provides heating and hot water from one compact unit. It heats water only when you need it, so there is no need for a storage cylinder. This makes it ideal for smaller homes or properties without loft space.
You can learn more about caring for yours in our guide to combi boiler servicing in London.
System Boilers
System boilers heat water directly and store it in a cylinder. They do not require a separate cold-water tank, which makes them suitable for families with higher hot water demand.
This option works well with many existing plumbing layouts and offers balanced performance throughout the home.
Regular or Conventional Boilers
These boilers use both a cylinder and a cold-water tank. They are common in older homes and large properties where multiple taps may run at the same time.
Our engineers frequently upgrade or service older systems across London, ensuring they continue to meet today’s standards.
Benefits of Central Heating Systems
Improved Energy Efficiency
Modern boilers use energy more intelligently. Condensing models extract more heat during operation, which helps reduce fuel use and lower monthly bills.
Consistent Warmth Throughout the Home
Unlike electric heaters that warm only one room, central heating systems spread warmth evenly. With thermostat control, you can maintain a comfortable temperature throughout the property.
Space-Saving Options
Combi and system boilers free up valuable storage space because they do not require tanks in the loft. This also helps reduce the chance of leaks or pressure issues.
Compatibility with Smart Technology
Many homes in London now integrate their central heating with smart home systems. This provides better scheduling, remote access and more control over energy use.
How to Maintain Your Heating System
Annual Servicing
A yearly boiler service helps keep your system safe, efficient and reliable. It also protects your warranty and reduces the likelihood of unexpected breakdowns.
We provide thorough central heating repair services across London, tackling issues such as poor performance or faulty components.
Bleeding Radiators
Air can become trapped inside radiators. This stops them from heating up fully. Bleeding the radiator removes the trapped air and restores proper heat flow.
Pressure and Filter Checks
Correct boiler pressure is essential for smooth operation. Clean filters also help prevent strain on the system. Our engineers can carry out these checks during routine servicing or callouts.
What Modern Heating Technology Can Offer
Heating technology has advanced significantly in recent years. From high-efficiency condensing boilers to smart thermostats and zoned heating, homeowners can now enjoy a tailored heating experience that reduces energy waste.
Many London property owners are choosing to upgrade their systems to achieve better control and improved performance. If you are considering an upgrade, we can guide you through the most suitable options for your property.
