Why does underfloor heating get dirty?

Underfloor heating is a closed system in which water circulates for years. Along the way, this water carries small particles of dirt, rust, and minerals. Over time, these particles accumulate in the pipes, resulting in slow heating, uneven heat distribution, and, in the worst-case scenario, a system that stops working.

Tyleen hoses: extra sensitive

Older systems with polyethylene hoses are more prone to sludge buildup and clogging. The result: cold rooms, an overworking central heating system, and rising energy costs. Recommended: have them flushed every four years .

Lime & hard water

In areas with hard water, minerals adhere to pipes, pumps, and valves. This hinders heat transfer and causes malfunctions. Professional flushing with suitable products removes limescale and restores flow.

Internal corrosion

Even modern pipes aren't immune. Rust particles migrate and accumulate in bends and constrictions, impeding flow. Regular flushing prevents harmful buildup and wear.

Signs that your underfloor heating is clogged

Unevenly warm floor
Cold spots in the house
Long heating time
Boiler or heat pump runs surprisingly often
Unexplained higher energy bill

Consequences of pollution

Higher energy consumption – working harder for the same result
Faster wear – extra stress on pumps and valves
More expensive maintenance – breakdowns and repairs are increasing
Shorter lifespan – never flush = faster replacement

How often to rinse?

Loan hoses: every 4 years
Modern systems: every 5 years
Direct: in case of blockage or unexpectedly high energy costs

How does New Heating approach this?

Step 1 – Inspection with thermal camera

We map the flow and locate problems without any cutting or demolition work.

Step 2 – Professional rinsing

We remove dirt, sludge, and limescale using a flushing unit and pH-neutral agents – safe for pipes.

Step 3 – Check with thermal camera

We immediately demonstrate that the system flows cleanly again and works efficiently.

Practice: completely clogged by sludge (Den Bosch)

The living room remained cold even though the boiler was running high. The thermal imaging camera showed several blocked circuits. After thoroughly flushing, the heat flowed evenly again. It reached the desired temperature within an hour, and energy consumption was immediately noticeably lower.

Customer case: old polyethylene hoses (Rosmalen)

No heat output and fear of complete replacement. Diagnosis, flushing, and inspection with a thermal imaging camera revealed: blockages were the culprit. After flushing, the system functioned like new again – no expensive replacement necessary.

What equipment do we use?

Advanced flushing units with adjustable pressure and flow rate
Thermal cameras for visible flow before and after
pH neutral cleaning agents, safe for pipes and components
Special tools for air removal and clearing blockages

Prevention is better than cure

Don't wait for complaints to pile up. By preventatively flushing every 4–5 years, you keep energy costs low, minimize malfunctions, and keep your system in top condition for decades.

Why choose New Heating?

Experience and specialization – busy with flushing every day
Transparent pricing – no hidden costs
Unique method – inspection and control with thermal imaging camera
Sustainable results – longer lifespan and lower consumption
National coverage – always on site quickly

Costs vs. savings

A rinse costs less than you think and pays for itself through:

Lower energy bills (10-20% savings are not uncommon)
Fewer malfunctions and lower maintenance costs
Longer lifespan of the installation

Frequently Asked Questions

How often should I rinse?

Loan hoses: every 4 years. Modern systems: every 5 years. In case of complaints or rising costs: immediately.

How much does it cost?

Depending on the number of groups and the level of contamination. We make clear pricing agreements in advance.

Can I do this myself?

Without a professional flushing unit, resources and experience, you will only remove part of the dirt and risk damage.

How do I know it works?

We show the measurements with the thermal camera before and after the rinse, so that the result is visible.

How long does it take?

Usually a few hours, depending on the size and condition of the system. You'll notice the difference immediately.

Sustainability and future-proof heating

Clean underfloor heating is crucial for efficiency and comfort, especially with low-temperature heating and heat pumps. Clogged pipes restrict flow and reduce efficiency. By flushing regularly, you maximize efficiency, lower energy consumption, and reduce CO₂ emissions.
