Radiant Floor Heating Systems - How Are Running Costs Calculated?

When it comes to energy-efficient heating solutions, radiant floor heating is easily the most effective option in the market. With the ability to transmit heat off the various surfaces and objects in a room, these systems create a warm, healthy, and cost-efficient living space for occupants. Given these superior benefits, a common question many users have is how running costs for radiant floor heating is calculated. Apart from the level of insulation of a given property and the temperature of the air outside, certain other variables play a more influential role in the costs incurred.

Calculating Radiant Floor Heating Systems Running Costs

Diving into the factors that contribute to the running costs of radiant heating systems, continue reading our blog to find out how to cut down on monthly heating bills!

Heat output in radiant floor heating systems

When it comes to the running cost of underfloor heating systems, heat output is a considerable factor.

Here, typical output values are around 120-130 watts per square meter, mainly in a property’s living areas. For residential buildings, this would generally include bedrooms, the kitchen, the dining room, and the living room. However, cost is likely to vary according to the size of the area being covered.

In terms of bathrooms, output is usually increased to around 200 watts per square metre in order to guarantee higher levels of warmth and comfort, and quicker response times.

Advanced control options for radiant heating

Another factor that contributes to cost, is the type of advanced control occupants enjoy over their radiant heating systems.

Here, smart thermostats are an excellent option, automatically regulating heat in order to maintain both comfort and energy efficiency. In this process, the temperature is often measured in 15-minute cycles, after which the right amount of heat is delivered in order to maintain a constant temperature.

In this manner, not only is heat wastage prevented but ‘peaks and troughs’ are avoided as well.

Off-peak electricity

Another gadget that can transform the expenditure incurred by radiant floor heating systems is a smart metre. Here, by making use of off-peak electricity rates, such as those set at night, monthly electricity bills experience a considerable decline.

While the installation of these devices can be a little costly, the long-term benefits of doing so far outweigh the initial expenditure. Property owners can thus ensure that their systems are running when electricity costs are low and can cut back during peak hours.

Properties are, therefore, kept warm and comfortable, with cost being reduced in a highly sustainable manner.

Flooring options

Another factor that proves to be just as decisive are flooring options for radiant floor heating systems.

In this regard, certain finishes are more effective than others. Here, thermal conductivity proves to be decisive when floor types are chosen for properties with these systems. Generally, dense and solid options such as tiles and stone enjoy a decent level of conductivity, which means that heat can be transmitted more easily from the heating unit to the floor. These can, in fact, be heated to a little more than 29°C for heating purposes.

Other finishes such as carpeting, vinyl, and linoleum, can also be used but aren’t as effective as the former. Wood finishing is also a popular choice and if chosen right, wooden flooring can effectively heat up a property owing to the high thermal conductivity of wood. If opting for this, however, many factors need to be considered before doing so and can be found in our previous blog on this topic.

Key takeaways

When it comes to radiant heating, running costs are not just low - they can also be further reduced with a few lifestyle changes and gadgets.

For property owners that are after the utmost efficiency, the tips set out above are likely to prove highly effective in cutting down on expenditure. By making a few smart decisions, enjoy energy-efficient underfloor heating and cooling, without breaking a sweat over exorbitant electricity bills.
