What Underfloor Heating Options Are Out There?

So what is underfloor heating and what can you choose from? Well to keep it simple you have wet underfloor heating and electric underfloor heating styles.

So let’s look at what each one is and the pro’s and con’s of having underfloor heating

Wet Underfloor Heating

A wet underfloor heating system uses pipes that are filled with warm water. Usually, these systems are powered by a boiler, but more people are starting to choose heat pumps as a popular alternative.

The pipes tend to be set into a layer of floor screed.

If you're starting from the ground up or thinking about a full-house heating setup, this is the top choice for underfloor heating.

Electric Underfloor Heating

Electric underfloor heating operates by placing a super-slim heating wire beneath your flooring.

It uses regular electricity to produce warmth, which then radiates up through the floorboards, heating both the floor and the room above to the temperature you set on the thermostat.

  • More energy efficient overtime.
  • Saves space by removing radiators.
  • Reduces cold areas of a room.

How Do You Install Underfloor Heating?

When you install underfloor heating, you’re basically laying down a system of pipes or wires under the floor. This way, the entire floor acts like a big radiator, warming up the whole area.

The usual method for installing underfloor heating involves placing pipes on top of insulation and beneath a screed.

The pipes are arranged in rows, coiling them as needed, and spaced out evenly to guarantee consistent heat distribution throughout the floor. They’re secured in place with pipe staples.

Next, they pour a self-leveling screed over the pipes, which hides them away. After pouring, they treat the screed with a chemical spray to help it set, then tamp it down and let it dry.

It's wise to give your screed around four weeks to dry completely before you start putting down flooring, but make sure to get advice from your supplier about the specific mix you have if you are doing it yourself, otherwise we would always recommend a professional doing it.

How Much Does It Cost For Underfloor Heating?

Whether your intention is to install a heating system for an entire home or to warm a specific room in the house the cost can vary.

So if you're a homeowner, you might be looking at a cost of around £3,000 to £13,000 for getting underfloor heating set up in a typical-sized home, including both materials and installation.

If you are concerned about costs, electric underfloor heating is probably easier on the wallet when buying and installing, but wet underfloor heating usually saves you more in running costs. Below is a quick table breakdown on the property type and the average cost per m of installation.

Underfloor Heating System and Property Type Average Installation Cost Per M²

Frequently Asked Questions

Can You Have Underfloor Heating Under Carpet?

Absolutely! Carpet is great for underfloor heating because it retains heat really well. This means you won’t need to rely on as much electricity or hot water to keep the room warm since the carpet keeps the heat around for a longer time.

How Long Does Underfloor Heating Take To Warm Up

This system heats up pretty quickly, usually taking just a few minutes to start warming up. You can expect all the rooms in your house to hit the right temperature in about 15 minutes.

However, with underfloor heating, it might take 4 hours or even longer to get to a cozy temperature, and that’s for a bunch of different reasons.

Will Underfloor Heating Heat My Room?

Sure, underfloor heating might not crank out heat like a regular radiator, but it still warms things up nicely for a cozy vibe. It spreads heat evenly across the floor, helping the room get to a comfy 25°C.

Is Underfloor Heating Gas Or Electric?

There are basically two types of underfloor heating systems: electric and warm water only. Both of them work in a similar fashion.

What Flooring Is Not Suitable For Underfloor Heating?

Carpets and overlays thicker than 2.5tog aren’t a good match for underfloor heating.

On the other hand, tile, stone, and polished screed floors are perfect because they let heat flow through really well.
