Radiant heat under a shower pan

There are various approaches to installing radiant heat under a shower pan, and it is important to consider the benefits and drawbacks of each method. Some installers suggest putting the radiant heat under the pan in a gypcrete pour or using QuikTrak, a system that does not affect the integrity of the pan. However, others argue that installing radiant heat under a shower pan may not provide significant benefits in terms of heat transfer to the pan.

One crucial consideration is the type of shower pan being used. If you are using a polyurethane shower pan, such as Tile Redi, it is recommended to put a skim coat of thin-set over the pan, let it dry, and then install the heating elements. This isolation of the pan from the heating elements is essential to maintain the product's warranty. On the other hand, some preformed shower bases, such as acrylic or manufactured stone, come with a built-in pitch, eliminating the need for a separate pan installation and radiant tube installation.

When installing radiant heat, it is also important to consider the surrounding structures. Some installers suggest putting the heat under the floor and even in one or two of the shower walls on a separate loop to avoid the headaches associated with tile bonding and cracking. Additionally, if you are installing a custom shower with a recirculation line, radiant heat under the pan liner can be beneficial, providing a warm floor and quick-drying shower floor.

While there are various methods for installing radiant heat under a shower pan, it is always important to consult with professionals and follow manufacturer guidelines to ensure the safety and effectiveness of the installation. Each project is unique, and factors such as floor height, drainage, and the presence of a membrane or liner can influence the best approach for installing radiant heat in your specific context.

Polyurethane shower pans with heated floors

It is possible to install radiant heat under a shower pan, but it may not be an effective way to warm the shower floor. One way to do this is to install the tubes above the membrane and run them up the walls, or under the pan if the floor height permits. However, this can be a complicated process and may not provide even heating. Some plumbers and tile setters may not recommend this method as it can be difficult to achieve the required slope to the drain.

Tile Redi shower floor pans, for example, are a polyurethane composite and the warranty is void if used with a heated floor. However, some customers have successfully used these shower pans with heated floors. If using a polyurethane shower pan with a heated floor, it is recommended to put a skim coat of thinset over the pan, let it dry, and then install the heating elements. This will help isolate the polyurethane pan from the heating elements.

WarmlyYours offers shower pans that are specifically designed to work with heated shower floors. Their products provide a compatible solution for those seeking to pair a polyurethane shower pan with underfloor heating.

If you are set on installing radiant heat under your shower pan, it is important to consult with professionals who have experience in this area. They can guide you through the process and help you avoid potential issues such as leaks and uneven heating.

Overall, while it is possible to install radiant heat under a polyurethane shower pan, there are important considerations to keep in mind. It may be more effective to explore alternative solutions, such as those suggested by WarmlyYours, to ensure a successful and safe installation.

Radiant heat in the ceiling

While some people have concerns about radiant heat in ceilings, it is a viable option for heating your home. Radiant ceiling heat is similar to heat from the sun, with electromagnetic waves transmitting heat to the room. This type of heating system works well in old or listed buildings where beautiful floors need to be kept, or in new buildings where you don't want to choose flooring based on its suitability for underfloor heating. It's also a good option for loft apartments where space is limited, as it saves room by being integrated into the ceiling.

Radiant ceiling heating works by pumping water through pipes or using electric heating elements concealed within or behind the ceiling materials. The ceiling temperature is typically between 23°C and 34°C, which feels comfortable. This type of heating system is laid over a large area, allowing it to work with low flow temperatures and save on energy costs. It also provides plenty of space for interior design options and can be installed in drywall construction or under plaster.

There are two main types of radiant ceiling heating: electric and hydronic. Electric radiant ceiling heating uses electric heating elements, while hydronic systems use water to transfer thermal energy. Hydronic systems are considered more flexible and robust, while electric systems are less efficient and have declined in popularity over time. However, electric radiant ceiling heating is still a viable option, as evidenced by a user on Reddit who shared that they have had a good experience with their electric ceiling radiant heat.

When installing radiant ceiling heating, it's important to consider the room height. Low-temperature ceiling heating is recommended for rooms with a height of 2.5 to 3.5 meters. For taller rooms, a higher flow temperature is required, and a combination of ceiling and wall heating may be suggested. Additionally, it's worth noting that radiant heat may not be suitable for every room in the house. For example, one person advised against installing radiant heat under the shower pan or toilet, as it could cause issues with the wax ring and drainage.

Overall, radiant ceiling heat can be a comfortable and efficient way to heat your home, but it's important to consider the specific requirements and constraints of your space before making a decision.

Radiant heat in the walls

While radiant floor heating is more common, radiant wall heating is an excellent option for those looking for an efficient, cost-effective, and unobtrusive heating system. Radiant heat panels can be installed inside walls, delivering heat to their surroundings through radiant heat transfer, a process that uses infrared radiation to warm people and objects directly.

Radiant wall heating is far more straightforward to install than floor heating systems, which require an extensive layout of pipes or cables under the floor and demand that you rip out and replace the entire floor. In contrast, radiant wall heating only requires you to remove the original drywall, install the panels, and then reinstall the drywall. The panels are thin and discreet, so they don't take up much space or detract from the aesthetics of the room.

Radiant wall heating is highly effective in providing uniform heating, and it does so without the stop-and-start pattern of traditional forced air, which dumps hot air into a room and then shuts off when a temperature threshold is reached. Radiant heat panels can be individually controlled for each room, making them an excellent choice for saving on heating costs when you have rooms that you don't frequently use.

Hydronic radiant wall heating, in particular, has gained popularity in Europe, where it has become a daily part of life for most Europeans. This system is easy to retrofit into walls at a fraction of the cost of floor systems, as only one-third of the material is needed. Walls can run at higher supply water temperatures, typically between 80°F to 150°F, enhancing the level of comfort provided.

Radiant wall heating is also an excellent option for allergy sufferers since it doesn't circulate air like forced air systems. Additionally, it can serve as an auxiliary heat source in conjunction with radiant floors, especially in bathrooms and high heat loss areas. When combined with HVAC systems, radiant walls provide contractors with a radiant tool that won't break the bank for their clients.

Radiant heat in the shower pan with fibreglass waterproofing

Radiant heating systems are a modern solution for warming up your shower pans and bathrooms. They are energy-efficient and provide a seamless look to your space. When considering radiant heat in the shower pan with fibreglass waterproofing, there are several options and important factors to consider.

Firstly, it is essential to decide whether to install the heating system under the shower pan or above it. Some people suggest that installing the system under the pan can be complicated and may not provide effective heat transfer to the shower pan. It is also important to avoid placing the heating cables under or through the curb as this can cause overheating and damage. Instead, it is recommended to install the heating cables over the curb in a routed section, securing them with a hot glue gun before filling the section with thin-set mortar.

Another option is to use a dedicated heating cable inside the shower area, separate from the bathroom floor heating cable. This ensures that the thermostat doesn't turn off prematurely when the shower is in use. Additionally, consider using a waterproofing membrane, such as Schluter-KERDI, over the heating system to protect the floors and walls from moisture migration and substrate cracks.

If you're looking for a quick warm-up, consider the Wedi Tile backer. It warms up fast and doesn't absorb water like other materials. However, be cautious with mosaic floor tiles as the heating and cooling process may cause cracking.

For those seeking a simpler installation process, a curbless shower with a single heating system can be a great choice. This option provides a seamless look and efficient heating.

Before beginning your project, carefully measure and plan the installation, ensuring you have the proper materials and following the manufacturer's instructions for your chosen system.

Overall, radiant heat in the shower pan with fibreglass waterproofing can enhance your shower experience, providing warmth and comfort.
