Does radiant flooring heat a room?
A room in a well-insulated modern house can usually be effectively heated using electric radiant floor heating. However, you must also consider the heat-loss value of a room.
What is radiant floor heating?
Radiant floor heating (RFH) involves installing electric heating coils or water -heated tubing under your home's floors. With an RFH system, the heat from the floor warms everything it touches and radiates throughout the room from the ground up. Think of RFH like heat from the sun.
How does an electric RFH system work?
Because an electric RFH system is usually used for single rooms, it's controlled either with a simple flick of a switch or automatically by thermostat. Since electric RFH system heating coils are installed between the subfloor and the floor covering itself, heating time is short.
Is RFH heating good for allergies?
Aside from the long-term cost benefits, RFH heating is silent heat, with no loud air ducts or furnaces to deal with. It's also better for people with allergies -- eliminating blown air can reduce dust mites by up to 80 percent [source: Warmly Yours ]. RFH systems fall into two categories -- electric and hydronic.
What type of heat source do I need for my house?
Gas-fired boiler. Kerosene, gas or solar water heater. Deciding which heat source to use depends on how large your house is and how cold it is where you live. For example, if you have a large home with high ceilings and live in Canada, you'll most likely need a boiler system.
Is RFH a whole house?
Some people with older homes choose single-room installations, like a kitchen or bathroom, instead of a whole-house system. The concept for RFH isn't new. Ancient Romans used hot water pipes to warm floors, and it's been the preferred heating system in Europe since the 1970s.
What floor do you put your bare feet on?
You slip out of bed and put your bare feet on a warm hardwood floor. When you head to the bathroom, you encounter heated ceramic tiles. In the kitchen, your feet meet a warm, tiled floor.
Why is concrete used as a thermal mass?
The concrete acts as a thermal mass to retain heat so that you have a large, hot block under your floor. Concrete owes its ability to retain heat to its density and low conductivity. Wood has a very high conductivity -- think of how quickly wooden decks or benches cool off when the sun goes down.

There are two main ways to assemble the system: through electrical resistances or thin hoses with a fluid running through them. The systems are incorporated into the floor during construction or renovation, remaining hidden and often inaccessible because they have been ...
How does a hydronic radiant floor work?
The Hydronic radiant floor, on the other hand, works through coils built into the floor, where the heated water will travel. The water stored there remains in a closed system, that is, it circulates uninterruptedly, alternately heating up and losing this energy to the environment. It can be heated in several ways, such as gas boilers, diesel oil, ...
What is the most common material used to heat a gas boiler?
In the past, steel and copper tubes were the most common. Today, most systems use flexible and resistant materials such as polyethylene and PEX (cross-linked polyethylene).
What is needed for electric floor heating?
In the case of electric floor heating, the system is greatly simplified. It needs an electricity supply, a thermostat (which will regulate the desired temperature), and electrical resistance, surrounded by insulating layers, similar to garden hoses. These are placed on a thermal blanket and then overlaid by the floor.
Why are floor systems incorporated into the floor during construction or renovation?
The systems are incorporated into the floor during construction or renovation, remaining hidden and often inaccessible because they have been concreted to the structure. By means of hot water or electrical resistance, the floor material is heated by contact, radiating to the air of the interior environment.
What is the law of thermodynamics?
There, the law of thermodynamics shows that warm, lighter air flows upward, and cold air travels downward. In this way, the environment is fully heated, avoiding heat waste and the formation of “heat islands” or cold spaces in the environment, as is often the case with traditional radiators.
What is Radiant Floor Heating?
For those who haven’t already heard about radiant floor heating (RFH), it could be just the answer to your winter woes.
How does floor heat work?
Radiant floor heat might sound like magic, but it’s really science. The heat is transmitted through electromagnetic waves, and when intercepted and absorbed, it turns into heat. This system allows radiant heat to function without direct contact.

What is radiant floor heating?
They’re most suitable for properties that run on time-of-use electricity rates. Floors that have a high thermal mass (the capacity to retain and store large amounts of heat), such as concrete, are most ideal for this configuration as it can be slightly more expensive to run on a consistent basis.
Do radiant floor heating systems need ducts?
As the name suggests, air-heated radiant floor heating systems require ducts inside the flooring system to provide hot air and distribute it throughout the property. Air-heated radiant floor heating systems are therefore not a viable option for residential apartment buildings.
What is radiant heating?
A key feature — and advantage — of radiant systems is that they distribute heat evenly. Unlike forced-air systems, which blow hot air into a space only to see it quickly rise to the ceiling, radiant floor heaters slowly emit heat from the lowest point of a room. This way, heat slowly rises and warms up the bottom portion of space, and its dwellers.
What are the two types of radiant floor heating?
There are 2 types of radiant floor heating: electric and hydronic. The former uses wires, cables, or mats that heat up beneath the surface of a floor once the system is turned on. The latter circulates hot water through a network of pipes embedded in the floor. Hydronic systems get their water supply from a boiler;
Why is hydronic radiant flooring important?
Like with any heating or cooling equipment, you need your hydronic radiant flooring system to be energy-efficient. That’s why proper sizing is essential — incorrectly sized systems can produce too much or too little heat, causing you to consume more energy to achieve the desired indoor climate. A skilled professional can determine the optimal system size by factoring in projected heating loads; these are based on the size of your home and your heating habits.
Can concrete floors be polished?
That’s why concrete floors are such a stellar medium for this type of heating system. The concrete can be polished, or have any type of veneer you like as long as it’s not insulative.
Is hydronic air better than forced air?
Both are vastly better for your indoor air quality and wellbeing than forced-air systems, as they don’t circulate air (along with dust, pollutants, and allergens) around the house.
Why do you need radiant floor heating?
Radiant floor heating is installed in the floor because heat rises. Heat doesn’t rise; radiant energy travels in all directions. You could install this system in the ceiling or walls if you wanted to, but it’s certainly more efficient to warm up with a walk across the floor.
Why do you need radiant heating under every floor?
In the old days, it made sense to install radiant floor heating under every floor because a pump of hot water ran through all the pipes to keep them toasty.
How much energy does radiant floor heating save?
7. Installing radiant floor heating can save between 10% and 50% in energy usage.
Can you put radiant heat under carpet?
You can install radiant floor heating underneath wood or carpet too, despite common misunderstandings about insulation. While different types of flooring vary in their insulating capacity, this in no way affects the effectiveness of radiant floor heating.
Can you overheat without radiant floor heating?
But it’s easy to combat this problem: add more windows, properly insulate your home or add a bigger HVAC system. It’s also worth noting that overheating can occur without a radiant floor heating system as well. It occurs naturally when there’s a lack of the aforementioned elements. 3.
Can radiant heating overheat a house?
