Help With Radiator Problems
Radiators can develop a range of problems, from uneven heating to leaks and faulty valves.
We can investigate issues including:
● Radiators that are cold or not heating properly
● Cold spots on radiators
● Leaking radiators or radiator valves
● Noisy radiators
● Faulty thermostatic radiator valves (TRVs)

Radiator Repairs You Can Rely On
A cold, leaking or noisy radiator can disrupt your comfort. We’ll assess the issue, explain your options and carry out the repair with care. From faulty valves and cold spots to circulation problems, DM Plumbing & Heating provides dependable radiator repairs to help keep your heating running smoothly.
Balanced Heat, Room to Room
If some rooms in your home heat up quickly while others remain cold, your heating system may require radiator balancing. Over time, water naturally takes the easiest route around your heating system, meaning some radiators receive more hot water than others.
Radiator balancing carefully adjusts the lockshield valves on each radiator so that hot water flows evenly throughout the entire system. This allows every radiator to warm up at a similar rate, improving comfort and efficiency.
Benefits of radiator balancing include:
● Even heat throughout your home
● Faster warm-up times
● Improved boiler efficiency
● Lower energy usage
● Reduced strain on your heating system
● Better overall comfort
Radiator balancing is especially beneficial after installing new radiators, replacing a boiler or carrying out a power flush. It is a valuable service to consider alongside radiator installation Bristol projects and radiator replacement Bristol upgrades.
Radiator Care & Flushing
Routine radiator maintenance is crucial for preventing breakdowns, boosting energy efficiency, and ensuring your central heating system operates effectively.
Our comprehensive services encompass radiator installation, bleeding radiators, checking valves and connections, balancing heating systems, inspecting for leaks or corrosion, and performing system performance checks.
We also offer radiator repairs and power flushing to eliminate sludge and debris. Over time, sludge and rust can build up inside your radiators and pipework, reducing heat output and driving up energy bills.
Our expert power flushing service is tailored to restore circulation and enhance overall system performance, ensuring your radiator maintenance and repairs keep your heating system in excellent condition.

Underfloor Heating Installations in Bristol
Benefits of having Underfloor Heating? Efficient Heating, Lasting Comfort
Whether you are looking for a complete UFH installation or want to incorporate underfloor heating into a wider heating or renovation project, we can assess your requirements and recommend a suitable system.
Underfloor heating distributes heat evenly across the floor, creating a comfortable living space without relying on traditional radiators. Because it operates at lower temperatures than standard central heating, it can improve energy efficiency while maintaining excellent comfort levels.
Benefits include:
● Even heat distribution throughout the room
● Lower running temperatures for improved efficiency
● Frees up wall space by removing radiators
● Quiet operation
● Compatible with many floor finishes
● Comfortable warm floors during colder months
● Ideal for bathrooms, kitchens, extensions and open-plan living areas
● Suitable for new builds and renovation projects
How Wet Underfloor Heating Works
Heated water is circulated through a network of pipes beneath the finished floor. As the pipework warms, heat is transferred upwards across the floor surface, creating a more evenly distributed temperature than traditional radiators.
The UFH manifold controls the individual heating circuits and can be used to divide the system into separate zones, allowing different areas of the property to be controlled independently where appropriate.
Because underfloor heating operates at lower flow temperatures than conventional radiators, it can improve heating efficiency when combined with modern boilers or renewable heating systems.
If you are planning a boiler installation in Bristol, underfloor heating can be designed to work efficiently with your new system.
Regular heating maintenance also helps keep your boiler and heating controls performing at their best.
Proper insulation and professional installation are key to achieving the best performance.
Benefits of Wet Underfloor Heating
Wet underfloor heating systems use heated water circulated through pipework installed beneath the floor to provide even, comfortable heat across the room. The system is connected to a suitable heat source, such as a boiler, heat pump or other compatible heating system, with the water temperature and flow controlled through an UFH manifold.
Benefits include:
● Comfortable, even heat: Warmth is distributed across the floor, helping to reduce cold spots and create a more consistent room temperature.
● Energy efficiency: Wet underfloor heating operates at lower flow temperatures than many traditional radiator systems, which can help improve efficiency and reduce energy use when correctly designed and controlled.
● Flexible zoning: The UFH manifold can divide the system into separate heating circuits, allowing different rooms or areas to be controlled independently.
● Design flexibility: With pipework installed beneath the floor, underfloor heating removes the need for wall-mounted radiators and can provide greater freedom when arranging furniture and planning interior spaces.
● Compatible with heat pumps: Wet underfloor heating is well suited to air source and ground source heat pumps because both systems operate efficiently at lower flow temperatures.
Water-Based Floor Heating
Water-based underfloor heating circulates warm water through pipes installed beneath your floor.
These systems are ideal for:
● Whole house heating ● New build properties ● Home extensions
● Large open-plan living spaces ● Properties with heat pumps ● Homes with modern condensing boilers
Wet systems can deliver excellent efficiency when designed and installed correctly, making them a popular choice for larger homes in Bristol, Long Ashton, Portishead and surrounding areas.
Electric Floor Heating
Electric underfloor heating uses heating mats or heating cables installed beneath the floor finish.
This option is particularly suitable for:
● Bathrooms ● En-suites ● Kitchens
● Conservatories ● Single room renovations ● Existing homes where minimal floor build-up is preferred
Electric systems provide fast warm-up times and are often easier to install in smaller areas, making them a great choice for bathroom renovations in Bedminster, Brislington, Bishopston and similar Bristol properties.
Comfort for Bathroom Floors
Underfloor heating is one of the most popular upgrades during a bathroom renovation.
It provides:
● Warm tiled floors
● Greater comfort during winter ● No bulky radiators ● More usable wall space
● Improved bathroom design flexibility
If you are planning a full bathroom installation in Bristol, underfloor heating is a smart way to improve comfort and create a cleaner, more modern finish. As experienced bathroom installers, we can incorporate underfloor heating seamlessly into your renovation project.
The Right Floor for Warmth
Underfloor heating works well beneath many flooring types, including:
● Porcelain tiles
● Ceramic tiles ● Stone flooring ● Luxury Vinyl Tile (LVT) ● Engineered wood
● Laminate flooring ● Suitable carpets with appropriate underlay
We’ll advise on the best flooring options for your chosen heating system.
Will Underfloor Heating Work?
In many properties, wet underfloor heating can be integrated with an existing heating system, but compatibility needs to be assessed before installation. The suitability will depend on factors including the existing boiler or heat source, floor construction, insulation, heat requirements and how the heating system is designed to operate.
For example:
● Modern combi boiler: A suitable modern combi boiler, such as a Worcester Bosch, Vaillant, Ideal or Viessmann combi boiler, can often supply a wet underfloor heating system. Appropriate controls, temperature regulation and an UFH manifold are required to manage the lower flow temperatures typically used by UFH.
● Existing combi boiler with radiators: UFH can sometimes be added to selected rooms while retaining radiators elsewhere in the property. The two systems operate differently, so the UFH circuits normally require their own temperature control and zoning rather than simply being connected directly to the radiator circuit.
● Mixed radiator and UFH system: A property can have radiators upstairs and UFH downstairs, for example. Separate thermostats and heating zones can allow each area to call for heat independently. The UFH manifold and associated controls regulate the temperature and flow through the UFH circuits, while the radiator circuit operates at its appropriate temperature.
● Older combi boiler: An older boiler may still be suitable in some circumstances, but its condition, output, controls and operating characteristics should be assessed before connecting a new UFH system.
● Air source heat pump: UFH can be particularly well suited to an air source heat pump because both are designed to operate efficiently at relatively low flow temperatures.
● Ground source heat pump: Ground source heat pumps can also work effectively with wet UFH where the system is correctly designed and sized for the property.
In many properties, wet underfloor heating can be integrated with an existing heating system, but compatibility needs to be assessed before installation. The suitability will depend on factors including the existing boiler or heat source, floor construction, insulation, heat requirements and how the heating system is designed to operate.
How Radiator and UFH Controls Work Together
Where radiators and underfloor heating are installed on the same heating system, the controls need to manage the different temperature requirements of each circuit. For example, a thermostat in the downstairs UFH zone can control the underfloor heating, while an upstairs thermostat controls the radiator zone.
The UFH manifold and associated controls regulate the water supplied to the underfloor heating circuits, helping to provide the appropriate flow temperature.
Depending on the system design, zone controls can also operate valves and communicate with the boiler or heat source when a particular area requires heat.
The exact arrangement depends on the boiler, heat source, existing controls and number of heating zones. We don’t assume that every existing heating system can simply be connected to UFH.
During an assessment, we can look at your existing heating system, floor construction and heat requirements to determine whether underfloor heating installation in Bristol is suitable and how the radiator and UFH circuits can be integrated correctly
