How does underfloor heating work?

If you're looking for a more efficient, comfortable, and modern way to heat your home or business, underfloor heating could be the perfect solution. Whether you’re considering electric underfloor heating for your bathroom or a full commercial underfloor heating system, this guide explains everything you need to know. Along with why more people are choosing Gasway for installation across Norfolk, Suffolk & Essex. 

Underfloor heating (UFH) is a smart heating system that works by distributing heat evenly beneath your floor surface. Instead of relying on radiators, warmth gently rises from the ground up, providing consistent, draught-free comfort.

There are two main types:

• Electric underfloor heating: Uses cables or heating mats under the floor. Perfect for single rooms or renovations.

• Wet (hydronic) underfloor heating: Uses warm water pumped through pipes and is ideal for whole-house systems or commercial properties.

Whether for domestic or commercial use, underfloor heating offers real advantages:

• Energy efficient – Heats at lower temperatures than radiators, saving energy

• Space-saving – No bulky radiators on walls

• Improved comfort – Even, radiant warmth underfoot

• Low maintenance – Once installed, UFH requires minimal upkeep

• Perfect for pairing with renewables – Works well with air source heat pumps. In fact we highly recommend if you already have underfloor heating you install and Air Source Heat Pump. If you've already got an Air Source Heat Pump, Install Underfloor Heating.

In homes, underfloor heating is especially popular for:

• Bathrooms, kitchens, and open-plan areas

• New-build homes or full refurbishments

• Energy-conscious households are installing heat pumps

With electric underfloor heating, you can easily add warmth under tiles or stone flooring without major building work. Wet systems are more cost-effective long-term and are best suited to entire floors or houses.

At Gasway, we design and install commercial underfloor heating systems for:

• Offices and retail premises

• Schools, healthcare, and care homes

• Warehouses and hospitality venues

Commercial UFH provides even heat across large floor areas, improves air quality, and reduces ongoing energy costs. It integrates seamlessly with commercial heating systems and air source heat pumps—helping you meet EPC and sustainability requirements.

Underfloor heating cost depends on several factors

If you're researching components or kits, you might see these terms:

• Heating mats or cables – For electric UFH

• UFH pipework – For wet systems

• Underfloor heating manifold – Distributes water to different zones (vital in wet setups)

• Smart thermostats – Control temperature by room or zone

• Insulation layers – Improve system efficiency

Looking to purchase kits? Many homeowners buy through trusted retailers like The Underfloor Heating Store, which offers installation components and full DIY packages. But if you want the system fitted and guaranteed, Gasway offers full installation and maintenance.
