Underfloor Heating – Definition, Working, Types, Installation Tips, Pros & Cons and Cost

Welcome to my blog on Underfloor Heating.

Are you tired of cold floors in the winter? Do you want a heating system that is efficient and provides even heat distribution? If your answer is yes, then you have come to the right place.

The traditional heating systems come with their own set of challenges. These systems work by heating the air in the room, which rises to the ceiling and then falls back down as it cools. This creates temperature variations in the room, making it uncomfortable to be in some areas. Additionally, these systems tend to dry out the air, causing issues like dry skin, itchy eyes, and sore throats.

Underfloor heating, on the other hand, heats the floor itself, which then radiates heat evenly throughout the room. This results in a comfortable temperature throughout the room, with no cold spots or drafts. Additionally, radiant floor heating systems do not dry out the air, making them a healthier choice for your home.

In this blog, we will dive deep into the world of floor heating systems. We will explore how they work, the different types of systems available, the benefits of using them, and how to install them. So let’s get started!

What is Underfloor Heating?

In underfloor heating also known as radiant floor heating, warm air is generated by installing hot water pipes or electric wires beneath the flooring. The heat then rises and uniformly warms the space from the bottom up.

Since there are no large radiators or vents that can take up valuable space, underfloor heating is an effective way to heat a room.

How Does Underfloor Heating Work?

A floor heating system warms a space by heating the floor directly, as opposed to warming the air, using radiant heat and electromagnetic waves. The floor is heated by floor heating systems, and that heat radiates up and is absorbed by other items in the room, thus warming the entire space.

Since they heat the air directly, conventional heating methods like space heaters are less effective than Underfloor heating. As a result, a room’s heat is distributed unevenly since hot air rises while cold air sinks. By physically warming the furniture and occupants of a space, radiant floor heating solves this problem.

Types of Underfloor Heating

There are basically two types available: (1) hydronic floor heating and (2) electric floor heating.

– Hydronic Underfloor Heating

In hydronic floor heating systems, the floors are heated via heating pipes beneath the floor that has a boiler as a heating source. The heated water travels through a series of copper tubes and radiators that are laid out beneath the floor. The floor is then heated by the radiant energy coming from the heated water.

The system can be installed in an existing structure or a new structure. Hydronic radiant floor heating is a type of heating system that is used for heating floors in commercial buildings, hospitals, restaurants, schools, gymnasiums, fitness centers, multi-unit dwellings, and more.

Unlike electric heating, which heats your house only when electricity is on, hydronic heating provides heating 24 hours a day. In addition to saving energy and money, hydronic systems can reduce the cost of your home’s cooling bills. Hydronic floor heating systems are most commonly installed in the United States. They are also installed in Canada, the UK, and Australia.

Compared to an electric system, the system’s long-term operating costs are lower, but installation is significantly more expensive. In general, installing hydronic systems into an existing structure or residence is less effective than installing electric systems since they take longer to install. A hydronic system needs routine maintenance, unlike an electric system.

– Electric Underfloor Heating

If you want to warm up your home fast, you can use an electric radiant floor heating system. The floors are heated by electric heating wires in an electric radiant floor heating system. Installation takes only a little time and uses a tonne of energy. You won’t have to worry about drafts when using an electric heating system. It is also energy efficient. All you have to do is plug it in and it works.

With a good electric floor heating system, you’ll feel warm right away. If you live in cold areas or in places where winters are harsh, it is a good idea to install a radiant electric Underfloor heating.  They are very reliable and energy efficient. These systems use heat pumps or steam generators. 

There are two main types of electric floor heating systems: mats and wires. Both types require installation. Mat systems include an adhesive backing, while wire systems come with a kit that includes specialized tape. Both types of systems are installed right on top of a layer of insulation.

An electric radiant floor heating system is a good choice for new construction or remodeling projects. The heating system uses heat pumps or steam generators. Heat pumps are very reliable. They don’t burn any fuel during operation, and they do not have moving parts. They can operate in any weather conditions.

How to Install Underfloor Heating – Tips

A proper installation of your floor heating system will be the difference between having an easy time and a frustrating one. A new heating system should always be installed using the correct building codes. You should follow the manufacturer’s recommendations for all equipment and connections and any other specifications they provide.

Your contractor will be able to explain everything to you before he or she begins the installation process. It is important to check that your floor heating equipment is properly connected and working before your next heating season. We always advise following a few standard installation instructions.

– Hydronic Floor Heating Installation Tips

Both new and existing buildings can have the hydronic floor heating system implemented. In order to install a hydronic floor heating system, you will need to follow these tips. 

  • – First design the System which will give you a free layout made according to your specifications as well as a list of the components you’ll need for the heating system. 
  • – Next, you will need to use a layout pattern. A layout pattern is a tool that will help you to place the pipes that will carry the hot water or steam throughout the room. This will allow you to create a pattern that will make sure that the pipes are properly placed and will not interfere with any walls or other fixtures.
  •  – In the joists where the tube will pass through, drill 7/8 inch holes. Regarding the quantity and location of the holes, make sure to adhere to local building codes. If your building has the common truss-type floor joists, you can skip this step.
  • – The PEX tubing should be inserted into the aluminium heat transfer plates one segment at a time.  Pass the PEX tubing through the previously drilled holes as you move along. On both ends, leave about two feet of additional tubing so that hookups for the hot water can be made later.
  • – The facing side of the insulation batts should be facing you when you friction-fit and staple the insulation in place. The additional two feet of heat tubing should remain exposed.
  • – Plumbing should be connected to a dedicated water heater, boiler system, (heat source). If you are unfamiliar with hot-water heating circuits, this is a good moment to contact an expert.

– Electric Floor Heating Installation Tips

Many people prefer electric floor heating systems because they are easy to install and they provide even heat throughout the whole room. This makes them very popular among homeowners who want to save money on their home heating bills.

A radiant heat floor can reduce energy bills by 20 to 50 percent compared to a regular floor in cold weather. Installing an electric heating system can be quite complex. It will require a licensed electrician to install it correctly.

  • – As much of the floor space as possible should be covered by electric floor heating mats or cables.
  • -Never overlap any floors in any way. In accordance with the manufacturer’s instructions, staple or otherwise secure the mats or cables to the flooring.
  • – Place the thermocouple that came with the floor s as close to the centre of the floor as you can while keeping it at least 12 inches from any walls.
  • – Having leveled the floor, now in accordance with electrical building requirements, connect the wires from all the floor heating mats to the home’s electrical system. Utilizing the included wiring instructions, attach the thermocouple wire to the thermostat.
  • – There are two types of systems available – embedded cable heat and radiant heat.
  • – We recommend insulation for the subfloor to reduce heat loss.
  • – You need to have 2 floor probes installed for the system to work properly.
  • – You need to have a dedicated breaker for the system.
  • – You should let thin-set or leveler cure for 24 hours.
  • – Make sure you have a licensed electrician install your heating system.
  • -Make sure that you understand how to operate and maintain your floor heating

Comparative Analysis of Hydronic and Electric Floor Heating

Systems for heating your floor to increase the comfort of your house can be hydronic or electric. However, there are some variations in how they function. Here is a brief summary.

Both approaches work well in general for Underfloor heating. The installation procedure, price, and heating up time are where the primary differences exist.

Hydronic radiant floor heating can be used to heat greater spaces than electric. But compared to electric radiant floor heating, which normally takes 30 to 50 minutes to heat up, it takes longer. This implies that before you need the heat, you might need to leave them on for a few hours. Additionally, they cost more to install but, with good upkeep, can survive for decades. Since the installation is more complicated, a specialist is typically needed. The boiler and related equipment also result in larger initial outlays.

On the other hand, the installation of electric radiant floor heating is simple. They are also better suited to smaller spaces or rooms and are initially cheaper. Furthermore, they are adaptable and work with many kinds of flooring. And finally, a well-designed electric floor heating system practically requires no upkeep to function.

A hydronic in-floor heating system would be perfect if you were remodelling your entire house or building a new one. On the other hand, if you are remodelling a room (or a few rooms) or only want to add floor heating to particular places in your house, an electric radiant floor heating system would be a better and more cost-effective solution.
