FAQS

General

Because a DIY home heating system is created with accessibility in mind, DIY Works made sure that all kits are affordable and easy to install. When you install your own home heating you can potentially save hundreds of dollars from installation costs. What you are purchasing is a complete kit with high quality components that are durable and reliable. In each kit, a step-by-step guide is included to make your home more comfortable in cold weather for you and your family. 

We understand that it can be overwhelming to decide with all the options that are available. Not to mention technical details that you need to consider. First, we invite you to read our guide to understand the advantages between a floor heating system or an overhead heating system.

If you prefer a floor heating system but unsure whether to opt for an undertile or an in screed, you can start with DIY Works Kit Selection Tool. It's a short quiz that assesses your responses. It will give you the best option when it comes to floor heating systems. You can start here to load the quiz.

Our DIY heating kits utilise radiant heating instead of forced air heating.

Radiant heating is a more efficient use of energy as it heats from the floor up then directly to objects and people giving the room an even and comfortable heating. This is different from central heating systems which heats a room with forced air. Warm air escapes the room sometimes causing uneven heating and uses up more energy to maintain consistent temperature. 

Radiant heating costs less than a cup of cappuccino to heat an average sized bathroom in a week! Less than 11cents/hr. This is based on Australia's average electricity prices.

The installation of an electric floor heating system is straightforward. Your mats will last up to 30 years given normal wear-and-tear. Virtually maintenance-free, this is why electric floor heaters are most sought when it comes to safety and efficiency. 

On average, a cold tiled floor will take between 10 to 20 mins to reach 27 degrees. This time varies depending on the thickness of your tile and tile bed. Floor insulation also plays a factor.

The Undertile Kit can be used with any floor finish. The tiler needs to pay extra attention when tiling with large, heavy tiles (not to damage the cable) or small mosaic tiles (not to have an uneven floor finish). Regarding timber floor finish, you can use the Undertile Kit unless specified otherwise by your timber supplier. Please note that the thermostat included with the Undertile Kit has an option for under timber floor heating, with which the floor heating is kept at a maximum of 27°C not to damage the timber floor.

Our heating mats are 3.5 mm thick which is generally perfect for undertile installation. Many tilers will use a 10mm or 12mm notch trowel when tiling, which when compressed should be about 4mm.

Ideally, the tiler should pour some tile glue or ardit mixed over the heating mat and let set over night before tiling. This will avoid any damage of the cables, or unevenness when laying down the tile. However, most tilers are comfortable with just tiling directly on top of the heating cables but extra care should be done. It is a good idea for the tiler to use a wooden or plastic trowel instead of a steel one to avoid damaging the heating cable. Another option is to spread the glue onto the tile instead of the floor.

It is still highly recommended that insulation is installed. This is to prevent loss of heat towards the ground. While it slows down heat loss, in turn it speeds up warm up times. Insulation is installed underneath the heating system for optimum efficacy.

Not only is radiant heating more straightforward to install compared to central heating, it is a more energy efficient heating system. Heat is evenly distributed because radiant heating increases temperature from the floor up directly to objects which then radiates heat across the room. Allergens are also significantly reduced since there is no airflow to disturb small particles in the house. 

How Tos

When it comes to floor heating systems, an undertile heating system is ideal for smaller rooms such as bathrooms, laundry spaces, small bedrooms. While an in screed heating system is ideal for larger rooms.
