Underfloor Heating Basics

There are two main types of underfloor heating systems – wet and dry. A wet system pumps warm water through pipes beneath the floor to create heat while a dry system uses electric coils under the floor to achieve the warmth. These systems are often associated with hotels and other luxury establishments but are now available for many homes as well.

The Benefits

One thing that many people like about underfloor heating systems is that they are hidden out of site. Unlike radiators they don’t take up wall space or affect where furniture can be placed as they are hidden beneath the floor itself. Because they spread under the whole room there are no warm and cold spots close to and far away from the radiator.

The Problems

There are two main issues with underfloor heating systems. The first is that they can be expensive to install, depending on the property and how it is constructed. They are popular for new build properties as the design can be incorporated in the house but might not work for some types of older property.

Conclusion

Whether electric or water based, underfloor heating systems are definitely a popular way forward in home heating. Many new build properties will incorporate one of these systems and homes undergoing renovation will often consider the same.

How long does it take for an underfloor heating system to heat up?

Electric underfloor heating takes close to an hour to heat up the room, this is why heating at a moderate temperature still gives a cozy feel around the room. The wire in the under-floor heating can heat up to around 80°C.

What is the maximum temperature of water used for underfloor heating?

Hydronic or water underfloor heating systems use warm water to heat up the floor. This water is heated to a max value of 50°C, as this is not at boiling level, there is no risk of burning or damaging of floor in case of breaks. The pex pipe used to transport this water is almost leak proof as this is a joint-less setup and no pressure points exist within the pipe.

How does an electric underfloor heating system work?

An electric underfloor heating system works on the principle of heated wires that conduct heat through the floor. Water or hydronic underfloor heating systems are based on heated water flowing through the pex pipes under the floor to heat up the floor by transfer of heat. This is better than a radiator as it will provide more uniform heating of the whole room, rather than one hot area and one cooler.

How long does it take for water to heat up under floor heating?

Water underfloor heating systems require 2 to 3 hours to heat up the room. This is because the water pumping through the pex pipes under the floor is nowhere near as hot as the wires in electric underfloor systems. Yet, this system is more economicalto run.

Does underfloor heating have a higher potential than the room?

Underfloor heating slowly radiates heat upward into the room, this means that the underfloor heating temperature should be at a higher potential than the room. Many things factor into the equation, the ventilation, insulation of the room, quality of conduction through the floor and the ability of the floor to retain humidity etc. The ideal temperature for a room is a theoretical concept, that is because the temperature varies from season to season, so keeping in mind that the temperature of the room will change over time, a temperature range was needed that could be applied at all times.

Can underfloor heating be used on a floor?

Yes, the underfloor heating is able to turn the floor a little warm to the touch by the continuous heat dissipation from the heating system. As the underfloor heating is installed to give a nice cozy feel to the residence, the flooring can heat up to a level that can be categorized as warm.
