Is Radiant Floor Heating and Cooling Right for Your Home?

Just consider a living space where the temperature is always ideal and there are no cold areas in the room or radiators blowing cold air. A home where the heating and cooling system is almost unseen, allowing more space and potential for home design. This is the promise of radiant floor heating and cooling systems, a technology that is quickly being adopted in North America.

Radiant heat is where your home is warmed from below through the use of infrared radiation. Unlike the other types of forced air systems that work by heating the air, radiant heat warms the objects and people. This makes for better dispersion and circulation of heat, thus enhancing comfort and possibly reducing energy consumption.

If you have ever wondered if radiant floor heating and cooling would work for you, give Morehart Air Conditioning and Heating a call. As experts in HVAC solutions, we will:

• provide you with information on what radiant systems are, how they operate, and what kinds there are
• discuss the advantages and disadvantages of the system to assist you in making the right choice about this new home comfort technology.

What is Radiant Floor Heating and Cooling, and How Does it Work?

Contrary to traditional systems that warm the air (like HVACs, duct systems, mini-split ACs, and dedicated heating systems), radiant floor heating and cooling systems work differently. Instead of warming the air, radiant systems heat the objects and people in their path. This fundamental difference in heat transfer is crucial to understanding why radiant floor heating is often more comfortable and efficient.

The Science Behind Radiant Floor Heating and Cooling

Radiant heat is based on the principle of heat transfer. Heat naturally moves from warmer objects to cooler ones. Radiant floor heating systems use this concept through heating elements installed beneath the floor. These elements emit heat, which warms the floor and, through radiation, warms the people and furniture in the room. This is more efficient compared to forced-air systems, which require grills or multiple vents to evenly distribute warm air.

Types of Radiant Floor Heating Systems

• Hydronic Radiant Floor Heating: This system uses water heated by a boiler and circulated through tubes or pipes under the floor. The warm water radiates heat, efficiently warming the space.

• Electric Radiant Floor Heating: This system uses electric heating cables or mats installed under the floor. The cables or mats warm the floor directly, providing consistent and efficient heat.

By focusing on direct heat transfer through radiation, radiant floor heating and cooling offer a more even and comfortable temperature distribution in your space.

Types of Radiant Floor Systems

We introduced these systems in the last section. Now, let’s see more about them:

Hydronic Radiant Floor Heating

At the heart of hydronic heating is a network of durable pipes, usually PEX (cross-linked polyethylene) installed in the floor. A boiler or water heater heats the water and this hot water is then pumped through the tubing with the help of pumps and valves. The heat from the water gets distributed through the floor and maintains equal temperature throughout. Some advanced hydronic systems may also include zoned control options, which allow you to set different temperatures for separate rooms in the house.

Hydronic systems are known to be energy efficient, especially when they are used with condensing boilers or water heat pumps. These heat sources get thermal energy from the air or the ground and are much more energy efficient than traditional furnaces.

Electric Radiant Floor Heating

Electric systems involve the use of electric heating cables or mats that are placed beneath the floor. These cables generate heat from electrical energy and emit it vertically. Another disadvantage of electric systems is that although they are easier to install and may be used for smaller areas or zones only, they have higher operational costs than hydronic systems because of the cost of electricity.

Electric systems are easier to install and can be cheaper initially than hydronic systems but in the long run, the cost of electricity is much higher. However, the recent innovations in electric heating including smart thermostats and programmable controls can assist in minimizing the energy cost.

We at Morehart AC can help you decide whether to go for an electric or hydronic system depending on your requirements, preference, and pocket.

Radiant Floor Cooling (and the Importance of Dew Point)

Although the most common use for radiant floor heating, many people are shocked to discover that radiant systems can also be used for cooling. The principle is similar: instead of pumping hot water through the tubing or panels located below the floor, the system pumps cool water. This chilled water circulates in the room and removes heat from the room thus providing a constant and cool environment.

However, there’s an important factor to consider with radiant cooling: relative humidity.

The dew point is the temperature level at which the air is fully absorbed with moisture and forms droplets of water. Condensation can form if the surface temperature of your radiant floor is below the dew point – this can lead to future moisture issues and possible damage to your floor.

This is why it is important to ensure that the floors used in radiant floor cooling systems are well insulated and that moisture is well controlled. Morehart AC pays much attention to the design and installation of these systems to make certain that the surface temperature of your floor is always above the dew point even during the humid period.

Radiant floor cooling, when installed and managed correctly, can be an effective and comfortable approach to cooling that is different from air conditioning systems that make noise and cause drafts. It is especially suitable for commercial structures and new constructions since the system can be incorporated into the structure easily.

The Benefits of Radiant Floor Heating and Cooling

Radiant floor heating and cooling offers a ton of benefits, from comfort to cost savings. Let’s break down why it’s becoming a popular choice for homeowners:

Comfort and Energy Efficiency

With radiant floor heating and cooling systems, heat is emitted evenly across your entire floor, eliminating cold spots and drafts that can make you feel chilly. Unlike conventional central forced-air systems with large radiators, radiant heat warms objects and people directly. This allows you to lower your thermostat setting while still staying comfortable, leading to significant savings on energy and heating bills.

Health and Indoor Air Quality

Radiant floor heating and cooling are not only beneficial for comfort but also for your health and indoor air quality. Because there is no air circulation involved, the system minimizes the movement of dust, pollen, and other allergens, which can be particularly helpful for those with respiratory issues or allergies. Additionally, radiant heat systems are effective at regulating indoor humidity, enhancing your home’s comfort during dry periods.

Aesthetics and Space-Saving

Say goodbye to unsightly radiators and bulky air vents! Radiant floor heating and cooling systems are installed beneath the floor, making them invisible and freeing up space. This design flexibility allows you to arrange your furniture without worrying about obstructing a vent or radiator.

Considerations and Potential Drawbacks

While radiant floor heating and cooling systems offer numerous advantages, it’s important to consider the potential drawbacks:

Cost

One of the primary considerations is the initial expense. Radiant floor systems often come with a higher installation cost compared to traditional HVAC systems. This is due to the complexity of integrating tubing or heating elements into the floor. Additionally, materials such as PEX tubing, manifolds, and controls contribute to the overall expense.

But, one has to look at the bigger picture at times. Radiant systems are known for their energy efficiency, which can lead to significant cost savings over time. The even heat distribution and ability to operate at lower temperatures can translate into reduced energy bills, especially in well-insulated homes. Morehart Air Conditioning  can provide you with a detailed cost analysis, taking into account factors like the size of your home, the type of system, and your energy usage patterns. We also offer financing options to help make radiant systems more affordable and accessible.

Installation

The other important aspect that should be considered is the way the equipment will be installed. Radiant floor systems are most often combined with new construction or with significant remodeling works when floors are being replaced. It is not impossible to install radiant heating in existing homes, but it may be more invasive and you may have to alter the existing floor coverings.

For efficiency and durability, we recommend that you get professional help from adequate technicians like Morehart AC and Heating. We have the experience and understanding of how to accommodate a customer’s needs in designing and installing radiant systems that work with the construction of the home.

Floor Coverings

Another factor that may affect the efficiency of radiant heating is the type of floor covering chosen. Certain materials such as ceramic tile, stone, and concrete are good conductors of heat and are compatible with radiant systems. Engineered wood and laminate flooring may also be used, although it is recommended to use the products that are created for use with radiant heat. Carpet, however, may provide insulation and may decrease the effectiveness of the system. Consult with Morehart Air Conditioning and Heating for the best flooring types for your radiant system to maximize heat transfer and comfort.

Response Time

Radiant floor systems are generally slower in terms of response than forced-air systems. This implies that it will take some time for your home to warm up or cool down depending on what you are setting on the thermostat. Radiant systems may not be as effective if you want to be able to easily alter the temperature in your home. Nonetheless, the steady, uniform heat of radiant systems is worth the relatively slower response time among homeowners.

Maintenance and Repairs

Radiant systems in general are easier to maintain than forced-air systems since there are no filters to change and no ducts to clean. However, some level of maintenance is still required, for instance, to check the pressure in hydronic systems or inspect the electrical connections in electric systems. Morehart AC provides maintenance services to guarantee the functionality of your radiant system and identify problems that need to be solved.

Although repairs are not very frequent with radiant systems, when they occur, they may take longer and be more expensive due to the in-floor installation. When selecting an installer, you should consider finding a company like Morehart AC and Heating that will continue to serve your radiant system and make sure it is running smoothly for many years to come.
