Coldbuster Floor Heating requires no ongoing maintenance costs.
Coldbuster Floor Heating comes with a 25 year warranty for floor heaters.
Coldbuster does not guarantee that your electricity bill will exactly match the calculated numbers.

Running Cost Factors

Running costs for electric floor heating can vary due to many factors and assumptions. This calculator provides a rough guide only, as conditions may differ.

Efficient Comfort

Running costs depend on electricity efficiency and rates. This estimate assumes a cost-effective energy source and an optimised tariff for heating.

Heating Duration

Energy use depends on how long the system runs. This estimate assumes heating is used only when needed and optimised with schedules.

Duty Cycle

A duty cycle shows the percentage of time the system actively heats. This calculator assumes a 50% duty cycle once the set temperature is reached.

Temperature Settings

Thermostat settings impact energy use. This estimate assumes a smart programmable thermostat is optimised for comfort and efficiency.

Insulation

Proper insulation reduces heat loss and energy use. This estimate assumes high-quality insulation in walls, floors, and roof.

Floor Substrate

Floor substrate affects heat retention and efficiency. This estimate assumes an energy-efficient substrate with insulation where needed.

Floor Covering Material

Floor coverings affect heating efficiency. This estimate assumes your flooring is suitable for underfloor heating and optimises heat transfer.

Ventilation: Air Leakage, Windows and Doors

Draughts from gaps in windows and doors increase heat loss. This estimate assumes all openings are well-sealed to maintain efficiency.

Building Characteristics

Building efficiency affects heating costs. This estimate assumes your building is modern or upgraded to meet current energy standards.

Outdoor Temperature and Local Climate

Local climate affects heating needs. This estimate assumes average regional conditions for your location in Australia.

System Efficiency

System efficiency affects energy use. This estimate assumes your underfloor heating is operating at optimal efficiency.

Zoning

Zoning allows precise heating and energy savings. This estimate assumes your system supports independent temperature control for each area.

Heating System Design

System design affects heat distribution and efficiency. This estimate assumes your heating system is properly designed and installed for optimal performance.

Usage Patterns

Regular usage helps optimise energy consumption. This estimate assumes consistent and moderate use of your heating system.

Ceiling Height

High ceilings increase heating needs. This estimate assumes standard ceiling heights of 2.4 to 2.7 meters for optimal energy efficiency.

Why is Floor Heating So Cheap to Run?

Coldbuster’s programmable thermostats learn your heating zones and optimise start times to reach your desired temperature efficiently. Once the set temperature is reached, the system runs on a duty cycle, using only a fraction of the energy.

Solar energy can further lower costs, especially with storage batteries. With no ongoing maintenance, Coldbuster floor heating is a true set-and-forget solution.

Quick Fact

Heating Under Furniture

Heating under furniture prevents cold spots. Omitting it under permanently fixed pieces has minimal impact on heater size and cost.
