Why are Water Underfloor Heating Systems More Efficient at Heating a Room than Radiators?

Both water underfloor heating systems and radiators transfer heat in different ways. Click here to learn more about the processes behind your heating solution.

Although, typically, the majority of people have long been reliant upon radiators as a way of bringing warmth into the rooms of our homes and businesses, water underfloor heating is now an increasingly popular choice for anyone hoping to increase the efficiency of their home’s central heating system.
The process of heat distribution is very different for radiators and water underfloor heating systems.  While radiators transfer heat via convection, water underfloor heating creates warmth through hydronic radiant heating.
Water underfloor heating systems are renowned for their efficiency at creating even warmth throughout the entire room. Read more about the differences between convection and radiant heating.

Convection Current Heating
While a radiator uses a combination of radiant and convection current heating, its effects are predominantly felt through convection — particularly when you are not sitting within a couple of feet of the heat source.
When air molecules make contact with a heat source — in this instance, a radiator — they expand. This lowers the hot air’s density and causes it to rise, and to push colder air around the room, towards the heat source. The heated air molecules cool as they collide with cool surfaces, and are then pushed back toward the radiator in a cycle of heating and cooling.
If a room is warmed by a radiator, then there will be a strong concentration of heat around the source, and a number of ‘cold spots’, meaning that your boiler will need to work very hard — and be programmed to a high setting — in order to achieve a comfortable temperature for you and your family.
What’s more, the high concentration of heat around the radiator often means that homeowners must open windows to keep that part of the room from reaching an uncomfortable temperature,

Radiant Heating
Heating by radiant energy is an incredibly common phenomenon; from the warmth we feel from the sun, to the heat emitted by a fire, radiant heat is a significant — and vital — part of our daily lives.
Unlike convection currents, which transfer heat through the air, radiant heating also warms objects and walls via electromagnetic waves. Since water underfloor heating systems produce radiant heat, the effects are much more efficient; rather than creating pockets of hot and cold air, every area within the room — even smaller nooks and crannies — can be warmed to the same temperature.
Since the space can be heated uniformly, you will not need to use such a high setting on your thermostat in order to achieve a desirable temperature, making it a far more efficient choice for any homeowner.
