Understanding Underfloor Heating

How Does Underfloor Heating Work?

Discover the inner workings of underfloor heating, a system that can transform your floors into a radiant heat emitter and create warm, even temperatures throughout your home.

Underfloor heating uses mainly radiant heat, which ensures there are no more cold spots and distributes a more even temperature for the body. The system works by distributing warm water through a circuit of pipes that are installed beneath the floor surface. The heat is monitored and controlled by intelligent thermostats, which allow individual room control.

Underfloor heating can work with any heat source, including conventional boilers and renewable ground/air heat source pumps. The system’s manifold connects pipe circuits installed in the floor, and when heat is switched on, the entire floor area is warmed to a temperature of 25°C – 28°C.

The manifold should be positioned centrally to reduce the length of pipe runs, and there are several ways to lay the pipe depending on spacing, layout, and fixing method.

Benefits of Underfloor Heating

Experience the luxurious and eco-friendly benefits of UFH. It covers a larger surface area and is up to 40% more efficient with a heat pump, adding a touch of sophistication to your home while freeing up valuable wall space. With UFH, you can enjoy a comfortable temperature without having to rely on ceiling temperatures that are too high or feeling cold spots from radiators.

Underfloor heating works by transforming your floors into a radiant heat emitter, offering a range of benefits that radiators simply can’t match.

Here are just a few of the benefits of UFH that make it a smart choice for any home:

– Covers a larger surface area, ensuring an even temperature throughout your home
– Uses lower water temperatures, making it more energy-efficient and eco-friendly
– Reduces dust movement, which is beneficial for those with allergies or asthma
– Can be used in combination with radiators for a flexible and efficient heating system
– Offers a longer lifespan than radiators, with pipework lasting at least 50 years

Drawbacks of Underfloor Heating

One of the main drawbacks is that it takes longer to warm up than radiators. With a wet system, it can take two or three hours to reach the desired temperature. This means that you can’t just turn it on and expect instant warmth. However, with proper planning and programming, you can still enjoy a comfortable home without wasting energy.

Another consideration is the raised floor profile. Underfloor heating will usually raise the profile of the floor. The amount it is raised by will depend on various factors such as the required insulation, pipe size, and whether you need a screed and floor finish. This may not be a problem for new builds or major renovations, but it can be a challenge for retrofitting a system into an existing home.

Despite these drawbacks, underfloor heating offers many benefits and can be an excellent choice for modern homes. As with any heating system, it’s important to consult with a professional heating engineer to ensure that you choose the right system for your specific needs.

Understanding Radiators

How Do Radiators Work?

Radiators are comprised of two panels with convector fins for heat circulation, which emit quick blasts of focused heat. They’re usually controlled with one single thermostat and TRVs and take up wall space (although there are some floor standing variations too).

Radiators only heat a small area of the house and may not directly reach all areas. They’re typically better suited for older, draughtier homes compared to well-insulated homes. Radiators can be combined with underfloor heating to create a flexible and efficient heating system. While they may be easily upgraded or moved, their running costs depend on insulation and lifestyle.

Benefits of Radiators

You may already have radiators installed in your home, and while they may not be the most energy-efficient option, they do have benefits that make them a popular choice.

One of the biggest advantages of radiators is their fast heating time, which can warm up a room in just 20-30 minutes. This makes them ideal for those who need quick heat and don’t want to wait for a long time to feel comfortable.

Another benefit of radiators is their wide range of stylish designs. With so many different styles and colours to choose from, you can easily find a look that matches your vision for the room. From designer radiators to coloured radiators, you can select what style matches your taste and complements your décor…

Companies like Best Heating and Stelrad offer a great range of options to explore. While radiators may not be the most energy-efficient option, their fast heating time and stylish designs make them a popular choice for many homeowners.

Drawbacks of Radiators

While radiators are a popular choice for heating homes, they do have some drawbacks. One major issue is that traditional radiators operate at a higher temperature, which uses much more energy and results in a larger carbon footprint compared to underfloor heating.

Additionally, radiators use convection to warm a room, which means that heat isn’t distributed evenly. This can result in warmer temperatures near the radiator and cooler temperatures in other parts of the room.

Another issue with radiators is that they can cause more dust circulation in the air. Heating using convection causes more dust particles to be transported in the air, which can worsen asthma symptoms and lead to more dust build-up on the back and top of the radiator.

As the air rises and then cools, it takes the dust particles with it, and this dust-filled air is then reheated and drawn up through the radiator, collecting behind it. These drawbacks may make you consider the benefits of underfloor heating, which offers a more efficient and evenly distributed heating option.

To summarize the drawbacks of radiators, consider the following points:

• Traditional radiators operate at a higher temperature, using more energy and producing a larger carbon footprint
• Radiators use convection to warm a room, resulting in uneven distribution of heat
• Heating using convection causes more dust particles to be transported in the air, worsening asthma symptoms and causing more dust buildup on the radiator
• Radiators take up wall space
• Radiator systems are controlled with one single thermostat and TRVs.

Cost Comparison: Underfloor Heating vs Radiators

While UFH has a higher initial installation cost, it can be more cost-effective in the long term due to its greater efficiency and lower running costs. Conversely, radiators have a lower installation cost but may have higher running costs depending on your boiler and energy costs.

To give a clearer comparison, let’s take the example of a 4m² bathroom heated for 4 hours a day. According to the average UK electricity price of £0.14/kW, the monthly cost for UFH would be around £10-£11.

In contrast, the running costs for radiators depend on your boiler and energy costs, with prices set by the Energy Price Guarantee. Depending on how you pay for your heating, you could pay around £0.10 per kWh for natural gas or £0.34 per kWh for electricity.

Practical Considerations

When deciding between underfloor heating (UFH) and radiators, there are a few important factors to keep in mind. To make the decision process easier, here are some practical considerations to keep in mind:

• Consider the maintenance requirements for both systems, as radiators may require more frequent cleaning, while UFH systems may need occasional maintenance to ensure they’re working at optimal efficiency.
• Keep in mind the type of home you have, as UFH is a popular choice for new builds and modern homes, while radiators are often found in older, draughtier homes.
• Remember that while the initial installation cost of UFH may be higher than radiators, the long-term savings and benefits may make it a more cost-effective choice.

By taking these practical considerations into account, you can choose the perfect heating system for your home that’ll keep you warm and comfortable all winter long.

Environmental Impact

Discover how your home can become more eco-friendly with an efficient and durable heating system.

UFH is more energy-efficient and has a lower carbon footprint compared to radiators. This is because UFH uses lower water temperatures, which reduces the amount of energy needed to heat your home.

The durability and longevity of both systems also play a role in their environmental impact. Radiators have a service life of 8-10 years, whereas UFH has a lifespan of at least 50 years, with pipework lasting even longer. This means that UFH is more sustainable in the long run and reduces the amount of waste generated from heating system replacements.

Additionally, UFH minimises dust movement and is beneficial for those with allergies and asthma, making it a healthier option for your home and the environment. Noise is another factor to consider when choosing between UFH and radiators.

UFH offers quieter operation compared to radiators, which can emit loud clanking noises as they heat up and cool down. This means that UFH not only reduces your carbon footprint but also creates a more peaceful and comfortable living environment.
