Cosy living room with underfloor heating

What is Underfloor Heating?

Underfloor Heating systems deliver warmth beneath the floor to efficiently warm a room.

An underfloor heating system comes with many benefits. In general these are; more comfort, less airborne dust and allergens & the ability to furnish with freedom.

Water Underfloor Heating systems reduce running costs and carbon emissions. Getting the best results from any heat source.

Radiators vs Underfloor Heating Comparison

  • Underfloor heating can provide the same or higher heat output than radiators.
  • Water Underfloor heating uses 35-45°C instead of 60-80°C Radiator water temperatures.
  • Lower temperatures reduce energy consumption and carbon emissions.
  • Installing Underfloor heating will: reduce draughts and allergen movement and allow more interior design options.

Electric vs Underfloor Heating Comparison

  • Both Electric and Water Underfloor Heating systems are popular choices for retrofit installations.
  • Electric Underfloor Heating is useful for a small area installation (small bathroom). But, much more expensive to run.
  • Water Underfloor Heating is more suited to a larger room or area, and 60% less to run than electric.

  • 60% less to run than electric underfloor heating
  • Easy to install, no digging up floors
  • Reliable long term use, long guarantees.

Electric UFH

  • Useful for small areas.
  • Expensive to run.
  • Certain systems have a shorter guarantee and more likely to fail.

Running costs

Underfloor heating uses much lower temperatures than radiators. Only needing water at 35-45°C, saving you huge amounts on your utility bills and ready for a net-zero future.

Electric has much higher running costs in comparison to water based systems making it suitable for smaller areas such as en suites but not for larger living areas and whole homes. For open plan kitchen and family areas, water based systems are more economic costing up to 65% less to run than electric.

An underfloor heating system can be an ideal and cost-effective way of keeping your home warm. It can be easily installed yet does require a fair amount of preparation and time.

Even before installing an underfloor heating system, there are other ways to reduce heat loss in your home which can prove easy and budget-friendly.

Many people have the perception that underfloor heating is incredibly difficult to install. Involving huge pipes with lots of digging, often leading to them thinking it will be a costly and stressful process. However, with a Wunda Rapid Response® system, this could not be further from the truth.

There’s no digging up floors and installation is easy and relatively hassle free. 75m2 could be laid over a weekend by competent DIYers ready for your professionals to hook up to your heat source.

Warm water is pumped from the heat source to the manifold. If the floor heating requires warm water, the thermostatic valve will open allowing heated water into the manifold. From the manifold, heated water is pumped around the floor heating pipes, returning to the manifold and then either released back to the boiler/heat source via the boiler return valve for re-heating or blended back into the floor loop via a one-way valve. When all rooms reach desired temperatures, the room thermostats will signal to the actuators and pump to shut down, this in turn stops heated water circulating through the floor.

Retrofitting underfloor heating can be a relatively easy process without the need to dig up the floors throughout your house. Wunda’s easy to install system comes with so many benefits, it warms up just as quickly as radiators and runs at a lower flow temperature which uses much less energy.

UFH circulates warm water through the plastic pipes to effectively heat up the floor first and allow for a warm living area with a cool ceiling. The water’s temperature can be between 35 and 55°C which is regulated by a mixing valve at the manifold.

Find the Ideal Temperature for Underfloor Heating in your home

Tile and natural stone floors work perfectly with underfloor heating as they are natural conductors. One thing to remember with these floor finishes is the thicker they are, the longer your response time will be and the longer the floor finish itself will hold the heat and take to cool down.
