The floors of the house act like a giant radiator and they provide a steady, even temperature to the entire house. The type of heat from an underfloor heating system is far superior when compared to traditional radiators. A radiator system will have hot and cold zones in the house and as you walk around the house, you will be drifting from hot to cool areas.

What is UFH?

Underfloor heating is a way of transferring heat into your home.
With underfloor heating, the room temperature is identical in all areas, always.
You can connect a heat pump, condensing boiler, stove or solar to your underfloor heating system.

Cost of UFH?

The cost will defer depending on size of house and if you want UFH in all rooms or just a select room/floor. (see rough price a few pages down)

Can I install UFH in an existing house?

Short answer is YES, but due to the amount of work that would have to be undertaken and the high cost – no one ever really does it.

Features & Benefits of UFH

True comfort

Since radiant heat is the most natural and comfortable form of heating. An underfloor heating system will provide true comfort levels, giving a gentle feeling of warmth throughout your home.

Perfect match with heat pumps

Underfloor heating goes hand in hand with heat pump installations. An underfloor heating system circulates low temperature water. A heat pump is most efficient when heating water at low temperatures.


The hidden heating elements of an underfloor heating system is also a safety bonus since you no longer need to worry about children burning themselves.

Saves you money on energy bills

With underfloor heating the thermostat of each room can be set at 2°C lower than a room heated by radiators. You can save up to 30% on your heating bills.

Health and Hygiene

An underfloor heating system reduces the circulation of airborne pollutants. It also helps to reduce house dust mites as the moisture content is too low to allow dust mites to live. This is great news for anyone with allergies or asthma.

Increased Humidity

With underfloor heating the heat comes from hot water, this also introduces moisture into the air and can reduce health problems caused by air which is extremely dry.


No radiators, you are free to position your furniture however you would like in your home.

How are the pipes covered/protected?

After the pipes have been placed by aqualified UFH installer, they are then covered in a liquid screed.

The basic screed construction for under floor heating systems generally follows the ‘floating’ screed construction, where a Damp Proof Membrane (DPM) and tacker insulation panels are laid over the concrete substrate before laying the heating elements of the underfloor heating system.

This is done to maintain energy efficiency and prevent heat from escaping to the base. All the external perimeters, edges and penetrations are also sealed with perimeter strip foam.

The heating elements are then fastened to the tacker boards and the screed is laid over them in such a way as to encase the heating elements. A cementitious screed should ideally be laid at a minimum overall thickness of 75mm and a thickness of at least 50mm over the heating elements.

Calcium Sulphate based screeds can be installed at a thinner section, generally at 60mm with minimum cover of 30mm over pipes. The screed should then be allowed to dry for the stipulated drying period before installing the final floor finish.

This is the basic screed construction followed for under floor heating systems

Control Panels

The panels are usual wall mounted and ae used to control the entire UFH system for the build. You can set time’s and temperatures for the various rooms

Mobile App

With some brands you can download an app that lets you control the UFH from your mobile. Meaning when your out, you can set your UFH to come on and when you get home you will have a warm home.


in some case you can even turn on your heating with a simple text (based on brand)

Why use UFH: More Benefits

Energy efficient & low running costs

Floor heating uses a lower temperature than standard radiators, heating costs are reduced, and savings can be achieved. Our systems require little or no maintenance, bringing the long-term costs down as well.

Design freedom

The system is invisible and frees up wall space as bulky radiators are not needed. This provides more space to be used and enjoyed.

Tailored temperature control

Using our precise thermostats, zoned heating control allows choosing the temperature wanted, in the areas needed and at the perfect time to suit the user schedule.

Reduced dust circulation and increased safety

The radiant heat produced by the system reduces humidity and air circulation, meaning that there are fewer dust mites and allergens in the indoor air. There are also no hot low-level surfaces or hard metal edges, as with radiators, making the system child friendly.

Comfort & warm floors

An even temperature, controlled by our precise and exclusive thermostats, creates a supremely comfortable environment. Warmth gently radiates from floor level, where the heat gently rises upwards, heating the room evenly.
