How to size Electric Boiler for Radiant Heat?

Reading Volume:

An electric boiler for radiant heat is a good choice for heating your home. Radiant heating systems work by using a network of pipes or electric heating elements installed beneath the floor, which heats up the surrounding surfaces and radiates heat throughout the room. However, how calculating the size of the radiant heat electric boiler is what you must know.

 

 

Can you use an electric boiler for radiant floor heating?

Yes, electric boilers can be used for radiant floor heating. Radiant floor heating systems work by circulating warm water through pipes embedded in the floor, which then radiates heat into the room. Electric boilers can provide the hot water needed for this type of system without the need for a traditional boiler fueled by natural gas or oil.

One advantage of using an electric boiler for radiant floor heating is that they do not produce any emissions, which can be an important consideration for those who are environmentally conscious or have health concerns related to indoor air quality. Additionally, electric boilers can be more efficient than traditional boilers, as they do not lose heat through flue gases or other exhaust emissions.

When considering using an electric boiler for radiant floor heating, it’s important to ensure that the boiler is properly sized for the application and that the system is designed and installed correctly.

 

Electric vs gas boiler for radiant heat

When it comes to selecting a boiler for radiant heat, there are two main options: electric and gas boilers. Each type of boiler has its own advantages and disadvantages, and the best choice will depend on a variety of factors.

Here are some of the key differences between electric and gas boilers for radiant heat:

  • Efficiency: Electric boilers for radiant heat can be more efficient than gas boilers, as they do not lose heat through flue gases or other exhaust emissions. However, the cost of electricity can be higher than gas, so the overall cost-effectiveness will depend on the specific energy prices in your area.
  • Installation cost: Electric boilers for radiant heat are generally easier and less expensive to install than gas boilers, as they do not require venting or gas lines.
  • Operating cost: The cost of operating an electric boiler will depend on the cost of electricity in your area, while the cost of operating a gas boiler will depend on the cost of natural gas.
  • Environmental impact: Electric boilers for radiant heat do not produce any emissions, while gas boilers can produce carbon monoxide and other pollutants. However, the environmental impact will depend on the source of electricity in your area.
  • Heating capacity: Gas boilers can generally provide more heating capacity than electric boilers, which may be important for larger spaces or colder climates.

When choosing between an electric or gas boiler for radiant heat, it’s important to consider your specific needs and requirements, as well as the cost and availability of energy in your area.

How efficient is an electric boiler for radiant heat?

Electric boiler for radiant heat efficiency

An electric boiler for radiant heat can be very efficient, with some models having efficiency ratings of up to 99%. This high efficiency is due to several factors:

  • An electric boiler for radiant heat doesn’t have the heat losses associated with the combustion of fuel, which means all of the energy used is converted into heat.
  • Electric boiler for radiant heat is often smaller and more compact than gas or oil boilers, which means they have less surface area to lose heat to the surrounding environment.
  • Electric boilers for radiant heat can be precisely controlled to match the heating demand of the space, which means they only consume energy when needed.
  • Some electric boilers for radiant heat use modulating controls to adjust the output of the boiler to match the heating demand, further improving efficiency.

However, it’s important to note that the efficiency of an electric boiler depends on several factors, including the size of the boiler, the heating demand of the space, and the temperature of the water used in the system. Additionally, the cost of electricity can vary significantly depending on location, time of day, and other factors, which can impact the overall cost-effectiveness of using an electric boiler for radiant heat.

How do you size an electric boiler for radiant heat?

Sizing an electric boiler for radiant heat requires a few key pieces of information:

  • Calculate the heat loss of the space: The first step is to determine the heat loss of the area you want to heat. This is usually done by calculating the R-value of the walls, floors, and ceilings, and then determining the total square footage of the space. Once you have this information, you can use a heat loss calculator to determine the BTU (British Thermal Unit) requirements for the space.
  • Determine the flow rate and temperature rise: Next, you need to determine the flow rate of the water that will be circulating through the radiant heat system, as well as the temperature rise required to provide the desired level of heat. The flow rate is typically measured in gallons per minute (GPM), and the temperature rise is measured in degrees Fahrenheit.
  • Calculate the boiler output: Using the information from steps 1 and 2, you can then calculate the output required for the electric boiler. To do this, you need to know the specific heat capacity of water (1 BTU per pound per degree Fahrenheit), as well as the efficiency of the electric boiler. You can then use a boiler sizing calculator to determine the appropriate size of electric boiler for your specific application.
