1. What type of UFH system will I need, water or electric?

With underfloor heating systems, your floor acts like a radiator. It heats the room from the ground up, through a series of pipes embedded in the floor. Different types of home require different UFH options – for example, thin retrofit underfloor heating for renovations.

There are two main types of underfloor heating systems:

With warm water underfloor heating systems, heated water is pumped around the property via a series of pipes embedded in the floor. Warm water systems are ideally suited to larger properties or those with lower levels of insulation, due to their higher heat output. These systems can be paired with renewables such as an air or ground source heat pump.

Electric underfloor heating systems consist of a series of cables which are laid over the floor deck. These systems and kits are perfect for installation in smaller areas like bathrooms. They heat up quickly, but they don’t retain the heat as well as warm water systems.

‘Wet’ or ‘dry’ underfloor heating can refer to whether the system uses water or electric, but also whether it uses a liquid screed installation process as opposed to other methods.

2. How are underfloor heating pipes or cables embedded in the floor?

It really depends what area you want UFH for and what kind of property you live in. For new builds and extensions, fitting the pipework into a layer of screed in the new floor is a popular choice. We can help you with the installation process and finding a supplier.

For underfloor heating on upper floors, Nu-Heat’s ClippaPlate® can be fitted between or over the joists using a metal diffuser plate. These are installed from below before the ceiling is in place or above, before the floor deck is fitted, adding no height to the upstairs floor level.

For home renovations, where you’re retrofitting underfloor heating in an existing house, thin and low profile UFH systems are ideal. Nu-Heat’s LoPro®10 can be laid directly over the existing floor, adding as little as 15mm total height build up. Most homes are suitable for UFH.

3. How will the underfloor heating fit my home?

Regardless of the age of your property, our underfloor heating systems are tailored to fit your home and how you live in it. Nu-Heat’s specialist in-house design software uses room-by-room heat-loss calculations to help create the perfect, energy efficient system for your home.

We look at the age and construction of your property; your home’s insulation and glazing levels; your location and orientation of your property; your chosen floor coverings; and how you use the different areas of your home. This also helps us estimate the cost of UFH for you.

If you’re creating a more eco-friendly home, underfloor heating can be paired with renewable options such as solar thermal panels, or air source or ground source heat pumps.

4. Which floor coverings are best for underfloor heating?

Stone and ceramic

Hard flooring is the most efficient type of floor covering for use with underfloor heating. Stone and ceramic tiles are the most thermally conductive floor coverings, allowing the energy to transfer quickly to the surface. Underfloor heating is popular in bathrooms and kitchens.

Timber and engineered wood

Engineered timber flooring is the best option for use with UFH because it performs well with fluctuating temperatures. Solid hardwoods and softwoods also transfer heat well, but it is essential to get the right thickness of the wood. Parquet can also be used as long as it is continuously glued to the screed or timber deck for good heat transfer.

Laminates and vinyl

These are practical and versatile flooring choices, but it’s important to check the manufacturer’s recommended maximum floor surface temperature to ensure the floor covering is compatible with underfloor heating. Always check your floor is suitable before installing UFH.

Carpet

Surprisingly, both water and electric underfloor heating can be used under carpet, but the combined tog rating of the carpet and underlay can be no more than 2.5. Otherwise, it will act as an insulator and stop sufficient heat reaching the room. Remember to check underlay too.

We recommend fitting a floor temperature sensor to protect more sensitive floor coverings.

5. How will I be able to control the UFH to fit in with my lifestyle?

Nu-Heat offers a range of thermostats to suit every home, from simple use dial thermostats to smart control and home automation-enabled wired or wireless solutions. You can even connect your underfloor heating to your smartphone by installing an app, with certain packages.

Dial thermostats allow you to set basic heating schedules and switch to holiday mode when you are going away. Programmable underfloor heating thermostats offer more flexible control, allowing you to zone different rooms or separate areas of your house.
