How to Calculate the Running Cost for Radiant Floor Heat
Radiant floor heating is an increasingly popular solution for home comfort, providing efficient and consistent warmth. One of the most crucial considerations for homeowners and builders is the running cost of these systems. Understanding these costs can help in making informed decisions about installing and operating radiant floor heating.
What is Radiant Floor Heating?
Radiant floor heating (RFH) systems use the concept of thermal radiation to heat a space. These systems can be hydronic (using water) or electric, with hydronic systems typically being more common in larger installations. Heat is distributed evenly from the floor up, creating a comfortable environment without the cold spots often found with traditional heating methods.
Factors Affecting Running Costs
Several factors influence the running cost of a radiant floor heating system:
Type of System: Hydronic systems generally have lower operational costs than electric systems but may have higher installation costs.
Energy Source: The cost of energy (natural gas, electricity, oil) in your region greatly affects running costs.
Insulation: Well-insulated homes retain heat better, reducing the overall energy required to maintain a comfortable temperature.
Thermostat Settings: Maintaining a lower temperature can significantly reduce running costs.
Square Footage: Larger areas require more energy to heat.
Climate: Colder climates will generally increase running costs due to the higher energy needed to maintain warmth.
Calculating Running Costs
Step 1: Determine the Area to be Heated
First, measure the total square footage of the area where the radiant floor heating will be installed. This measurement is crucial as it directly impacts the energy required for heating.
Step 2: Identify the System's Power Consumption
For electric systems, this is typically measured in watts per square foot. Hydronic systems, on the other hand, will use BTUs (British Thermal Units) per square foot. Manufacturer specifications will provide these values.
Step 3: Calculate Energy Usage
Electric Systems: Multiply the power consumption (watts per square foot) by the total square footage.
Total Watts = Watts per Square Foot x Total Square Footage
Hydronic Systems: Multiply the BTUs per square foot by the total square footage.
Total BTUs = BTUs per Square Foot x Total Square Footage
Step 4: Convert to Kilowatt-Hours (Electric Systems Only)
Convert the total watts to kilowatt-hours (kWh), since electricity is billed in kWh.
Total kWh = Total Watts / 1000
Step 5: Estimate Daily and Monthly Usage
Estimate the number of hours the system will run each day. This can vary based on thermostat settings and external temperatures. Multiply the daily usage by 30 to get the monthly usage.
Daily Usage:
Daily kWh = Total kWh x Hours per Day
Monthly Usage:
Monthly kWh = Daily kWh x 30
Step 6: Calculate the Cost
Multiply the monthly kWh usage by the cost per kWh from your energy provider. For hydronic systems, convert BTUs to the fuel cost based on the type of fuel used (natural gas, propane, oil).
Electric Systems:
Monthly Cost = Monthly kWh x Cost per kWh
Hydronic Systems:
Convert BTUs to the cost of fuel. For example, natural gas costs are typically measured in therms (1 therm = 100,000 BTUs).
Monthly Cost = (Total BTUs / 100,000) x Cost per Therm
Additional Considerations
Thermostat Controls: Smart thermostats can optimize heating schedules, reducing unnecessary energy consumption.
Zoning: Dividing the home into zones allows for heating only occupied areas, improving efficiency.
Energy Prices: Fluctuations in energy prices can significantly impact running costs. Monitoring and adjusting usage based on price changes can help manage costs.
Running Cost Calculator
To simplify the process of estimating your running costs, use the following calculator. Input your system type, energy consumption, and local energy costs to get an estimate.
