FAQ

Heat Controllers

How can programming save money?

Programming saves money because you do not unnecessarily heat your home when heating isn't required, i.e. during the day while you’re at work. By lowering the heat during the day, you can realise significant savings: each 1ºC the temperature is lowered during an eight-hour period equals a savings of 2%.

What is the advantage of a pre-programmed thermostat?

Our pre-programmed thermostats come factory-set with a typical energy-saving schedule. For many households, there will be no need to personalise or re-program these factory settings since they are already appropriate for a typical household's schedule. This means that the thermostat is ready to start saving money as soon as it is installed.

 

Undertile Heating

How thick is the element?

The undertile heating element, including the full earth braid and double insulation is between 2.2 to 2.4mm thick.

Are the heaters water resistant?

Yes the undertile heaters are 100% water resistant.

Are the heaters safe?

The Warmup undertile elements have been tested and approved by all the appropriate safety testing bodies. Each individual heater is thoroughly tested before it leaves the factory prior to installation and again during commissioning.

To comply with these safety standards all heaters must be used in conjunction with an RCD. RCD stands for Residual Current Device and is sometimes called an earth leakage breaker or earth leakage detector. RCD's are more sensitive than fuses. They detect any slight loss in current and immediately shut off all power to the circuit before there is a risk of shock.

What sort of floor preparation is required?

As a rule of thumb, if your floor is acceptable for tiling, then it will be acceptable for heating. On particle board or wooden subfloors we recommend using tile and slate underlay - Hard or sharp particles should be removed and the floors should be completely free from dust, dirt and grease. Waterproofing, if required, is typically done after the heating has been installed but this may vary depending upon the local council requirements and installation details. If in doubt, please contact your local representative.

Can I walk on the installed tile heating before tiling?

The tiler should be the only person to walk on the floor once the heating elements have been installed. If you need to alk on the floor, you should do so only wearing socks or soft shoes.

Does my tiler need any special adhesives?

The floor must be laid with either a flexible adhesive or a flexible additive. Your tiler or tile supplier will be able to advise you on the best type of adhesive for your installation.

How long will it take for the floor to heat up?

This depends on the thickness of the tiles, whether the subfloor is concrete or wood, general levels of insulation and floor insulation. On an insulated wooden subfloor it takes approximately 20 to 40 minutes for the tiles to feel warm, then approx 45 to 90 minutes to heat the room. On an uninsulated concrete floor it will take longer. The floor will also take longer to cool down after the heater has been turned off. 

On an insulated wooden subfloor, in a well insulated room, the floor will be warm in 30 minutes. On an uninsulated concrete floor in a poorly insulated room, it could take up to 5 hours to heat the floor. The longer it takes to heat the floor, the longer the floor will retain the heat.

How much will it cost to operate the heating?

A typical installation will cost approximately 1.5 cents per hour per square meter of heated area when warming up. Once the floor has warmed up, the thermostat switches the heater on and off automatically. In normal winter conditions, if the heater is the only source of heat in a reasonably insulated room, you can expect the heater to be on for between 30% and 50% of the time. This time will obviously vary depending upon the climatic conditions and the comfort levels required. Every 1ºC reduction in the temperature setting of your thermostat will result in a 6% reduction in power usage over 24 hours.

An average bathroom (500 watts) will cost approx $ 15 to $ 20 per month using an electronic floor thermostat at normal operating temperature.

***Please be aware that actual costs will vary between electricity supply companies.

 

Undercarpet Heating

Are the heaters water resistant?

All Warmup undercarpet heaters are 100% water resistant.

How long will it take for the floor to heat up?

The length of time it takes to warm the floor will depend upon the density of the carpet and the subfloor. As with undertile heating, an uninsulated concrete floor will take longer to heat up but will retain the heat for longer. Undercarpet heating will not provide you with an instant source of concentrated heat in the manner of a fireplace or bar heater. Rahter the whole room is gradually warmed at the same time. 

 

Insulation Boards

What is Marmox?

Marmox Insulation board is an insulation board technically designed as the perfect complement to undertile heating. Marmox is an extruded polystyrene board, reinforced and covered on both sides with a fibreglass mesh and a thin cement polymer mortar.

What are its benefits?

It significantly reduces heat loss to the substrate by acting as a thermal barrier. Marmox intensifies the effects of undertile heating so you get a very responsive, very efficient floor heating system. By using Marmox, you will find that after switching on your heating, your floor tiles will warm up in about 15-20 minutes, even on a cold concrete floor. Being totally waterproof, it is ideal for use in bathrooms and showers. Marmox also has excellent acoustic cushioning properties particularly in reducing footfall and the echo often associated with large tiled areas.

Can Marmox replace tile and slate underlay?

Yes provided the subfloor is structurally sound and flat.

What should be the thickness of the Marmox board?

The thicker the board, the better the heat insulation. If you have an exisiting floor to insulate, you may be restricted in the thickness you can add to the floor because of the height from the finished floor to the underside of your doors. But even when using our thinnest Marmox boards you will notice the benefits of effective insulation.

Is Marmox Insulation Board internationally certified?

Underfloor Heating (general questions)

Can I use Warmup Undertile Heating system as the sole heat source?

If your room is well insulated and complies with modern insulation levels as set out in the current building regulations you should be able to use Warmup Underfloor Heating as the sole heat source.

What type of flooring can I use over the Warmup system?

Warmup has a range of specifically designed loose wire and matting heating systems for use under tile, natural stone and under carpet.

Where can I buy the Warmup system?

We have many approved distributors, call 0800 WARMUP or click here to find a distributor near you.

Do I need specialist skills to install the Warmup system?

No specialist skills are required. The Warmup system is designed so that any contractor or competent do-it-yourselfer can install it. The kit comes with a comprehensive installation manual and our instructional videos are available should you need any assistance during installation. A qualified electrician should always undertake the connection of the heater to the thermostat,

How soon after installation can I switch the system on?

For Undertile Heating systems, the heater should not be made fully operational until such time as the tile or concrete installer has confirmed that the cement materials (i.e. adhesive and grout) are fully cured. This may be anything from 1 - 3 weeks. Turning the system on too early could lead to the cement drying out too quickly, creating an unsuitable subfloor.

For Underlaminate Heating systems, once wired and tested the system may be switched on immediately.
