“Next Level recently installed underfloor heating pipes and screed to our self-build… Alan and his team delivered on their promises from start to finish. They turned up when they said they would, did a first-class job laying both the pipes and the screed, and communicated well before, during and after. Very competitively priced too!”

Key takeaways

  • Balancing underfloor heating systems is essential for ensuring seamless heat distribution and comfort throughout your property. Improper balancing can lead to uneven temperature distribution, cold spots, increased energy consumption, and system noises.
  • Balanced underfloor heating systems offer enhanced comfort, even heating, energy efficiency, cost savings, and a prolonged system lifespan. Proper balancing involves assessing the system, adjusting actuators and actuator valves, calibrating thermostat temperatures, adjusting the flow rate, and bleeding the system for water systems.

What is Underfloor Heating?

Underfloor heating is a form of central heating system that provides warmth throughout a room or property from below. You can choose from two main types of underfloor heating systems: water and electric.

Water underfloor heating Electric underfloor heating
Water underfloor heating involves installing a series of pipes underneath the floor. When the system is turned on, warm water will flow through these pipes and heat the area above. These systems are more expensive to install but more cost-effective in the long term. They are also better for heating up larger spaces Electric underfloor heating involves a series of cables or heating mats installed below the floor’s surface. These will work to provide warmth to the property above once electricity flows through them. They are cheaper to install but might raise slightly more expensive monthly costs. These are ideal for when you want to heat up an individual room.

Signs of unbalanced underfloor heating

If you’re considering having an underfloor heating system installed on your property, you need to ensure you use an expert or have the correct know-how yourself. Improper water flow can lead to an unbalanced system, affecting its performance and longevity. If the job is incorrect and the system is unbalanced, you might notice the following:

Uneven temperature distribution

The whole point of underfloor heating is that it fixes one of the downfalls of radiators – not effectively heating up an entire room. However, if you notice that you feel different temperature distribution throughout the room, this might be due to unbalanced underfloor heating. Maintaining an optimal temperature differential between the flow and return pipes is crucial for even temperature distribution. This can cause inadequate water or electric flow to specific zones and disrupt your comfort.

Cold spots or overheating areas

Like uneven temperature distribution, you might find that an unbalanced underfloor heating system gives you extremely cold spots at one end of the room but uncomfortably warm areas at the other. This is another issue with unbalanced underfloor heating, which might have caused a valve malfunction or caused air pockets in your water system, preventing proper circulation.

Increased energy consumption

This sign will most likely happen with an unbalanced electric underfloor heating system. Of course, you don’t want to have to pay more than you’re feeling in heat, so if you are experiencing extortionate energy bills, you might need help. This is because unbalanced heating systems lead to overcompensation in specific zones, which leads to more energy use.

Unusual noises from the system

When you turn on an underfloor heating system, you want to experience complete comfort. But you can’t feel entirely comfortable hearing a wide range of clanging, gurgling, and other loud sounds from your system. This is due to imbalances causing an increase in pressure and turbulence, and it can become an uncomfortable burden you don’t wish to experience daily.

Importance of balancing underfloor heating


Balancing underfloor heating is crucial for maintaining an efficient and comfortable heating system.

From the last section, you could see what problems unbalanced underfloor heating can bring you, but what benefits do you actually get when it is balanced? Here are just some of them:

Enhanced comfort and even heating

The primary purpose of an underfloor heating system is to provide you with complete warmth across a large area like a room. Unlike radiators, balanced underfloor heating can provide even heating distribution throughout the room, so you don’t need to spend more time in one area than another. Regulating the emitter flow is crucial for achieving this even heating distribution. This leads to enhanced comfort and makes your property worth living in.

Energy efficiency and cost savings

Everyone knows that heating isn’t free, and there are often high costs associated with running it for long amounts of time. However, you will likely experience lower energy bills when you have balanced underfloor heating. An auto-balancing actuator plays a crucial role in maintaining a consistent temperature differential, ensuring the system operates efficiently without the need for manual monitoring. This doesn’t just help you save money, but it contributes positively towards helping the environment.

Prolonged system lifespan

Underfloor heating systems are an investment, so you want one that will stay with you for as long as possible. At Next Level, we offer underfloor heating that will remain with you for over 50 years, and that is because we balance our systems. Balanced systems are known to have a much longer lifespan, and that’s because they face fewer problems and require less maintenance.

How to Balance Underfloor Heating

Step-by-step guide on balancing your underfloor heating system

If you wish to install underfloor heating yourself and want to ensure it is efficient and balanced, follow these steps:

1

System Assessment

Inspect the manifold for damage, check for leaks and air pockets, and ensure thermostat functionality. Underfloor heating manifolds are crucial components in wet underfloor heating systems, and their proper assessment is essential for overall system performance.

2

Balancing Actuators

Understand actuators, adjust flow rates for each zone by accessing the manifold, and ensure valve functionality. Auto-balancing actuators use two temperature sensors to measure the temperature differential between the flow and return pipes, allowing for real-time adjustments to maintain a consistent temperature, thus improving efficiency and convenience in system operation.

3

Temperature Adjustment

Calibrate the thermostat with a calibrated thermometer, set temperature limits for each zone, and fine-tune for comfort.

4

Bleeding the System

Again, for a water underfloor heating system, you should finish with this step. Look out for any air pockets in the pipes in your system. If there are any, use a bleed key or valve to release trapped air. Open the bleed valve on your manifold and then bleed the system until there is no more air and water flows efficiently.

Frequently Asked Questions About UFH Installation & Balancing

The most common questions we get from clients about balancing underfloor heating systems

Yes. Even brand-new underfloor heating systems must be balanced to ensure hot water (or electrical flow) is distributed evenly across all zones. Without balancing, you risk cold spots, overheating areas, and inefficiency.

Most residential installs (including screed, piping, and full balancing) take 2–4 days depending on the property size and number of zones. Larger or multi-zone properties may take slightly longer.

Yes — with us, balancing is not optional. It’s built into every installation to guarantee comfort, efficiency, and long-term performance from day one.

While electric systems don’t use water, they still require careful layout and zoning to avoid hotspots or inefficiencies. Balancing in this context means planning, zoning, and installing to spec.

No — not for water-based systems. The manifold is essential for controlling the flow and temperature of water across different circuits. Without it, you can’t manage individual zones or guarantee comfort.

A properly installed and balanced water-based UFH system can last over 50 years — especially when the pipes are protected by screed and the system is flushed and balanced correctly.

Multi-zone systems benefit even more from professional balancing. Each room can be controlled individually, but only if flow rates and temperature differentials are set correctly through the manifold

Yes. Excessive heat in specific zones can cause stress on floor finishes, warping on timber, or cracking in screeds over time. Balancing prevents this.
