The Best Heating Mat: Our Choices
Guide: Questions you should ask yourself before buying a heating mat
For what purpose should the heating mat be installed?
A heating mat is best suited for small areas. The power consumption is still low, the heat emitted is just right and the costs are kept within limits. This makes it perfect for small grows.
However, if larger areas are to be heated, larger heat mats must be installed, which could be more expensive. Therefore, a heating cable is more suitable here, as it heats exactly the right places and thus does not give off unnecessary heat.
This saves a lot on electricity costs and is also practical, as heating cables are usually buried and therefore not visible. For large greenhouses, a gas heater is also recommended, as it can heat a large area and costs less to consume than comparable heaters.
For whom is a heating mat suitable?
But not only that is a huge advantage. The otherwise cold winter can also be used for growing. This means you can watch your plants grow even in winter. Of course, a heat mat can be used not only in winter or for greenhouses.
It can be used just as well on a windowsill in the sun. Especially city dwellers can now finally grow their own tomatoes or lettuce. Thus, a heating mat is suitable for everyone, as it requires little space and has a great benefit.
What does a heating mat cost?
|Heating mat||15-50 €|
|Heating mat with thermometer||50-150 €|
|Heating mat with thermometer and floor sensor||90-200+ €|
For heating mats, a basic distinction can be made between heating mats with thermometer and heating mats with thermometer and floor sensor. Depending on the brand and manufacturer, the prices also differ accordingly.
What alternatives are there to a heating mat?
A polystyrene board is especially useful in winter. A windowsill made of stone likes to get cold. As a result, water absorption slows down and the roots start to rot. A polystyrene board is perfect for this.
All you have to do is lay it on the windowsill. Then the plants can be placed on it. Within a few days you will notice the first differences. The plants need more water and grow better.
Consequently, the condition of the plants improves quite quickly and can be recommended for everyone, especially in winter.
Heating cables are a practical solution to heat the entire greenhouse so that the roots are always warm enough. They are already available at a reasonable price, so they are accessible to everyone.
However, the installation is much more difficult than with a normal heating mat. The floor of the greenhouse must be excavated so that the cables can be installed at a depth of 20-30 centimetres. Once this is done, however, you have the perfect floor heating for your greenhouse, which is not visible.
If your greenhouse, like most, does not have a socket and you do not want to build an expensive solar system with storage, a gas heater is the right solution. A gas heater produces a flame that heats the greenhouse.
Larger versions can be equipped with an additional ventilation system that distributes the hot air in the greenhouse. Practical: 99% of the gas is converted into heat. The disadvantage of this heating system is that it is expensive to buy and the consumption costs are additional
Paraffin is a light liquid, oily or waxy, combustible, odourless and tasteless, non-toxic and electrically insulating, water-repellent, fusible with fats and waxes and inert to many chemicals.
This makes it perfect for heating. An obvious option with similar properties is petroleum. Petroleum is also suitable for greenhouse heating. As this heater does not produce as much heat, it is only suitable for smaller greenhouses.
However, as paraffin and paraffin are quite expensive, the costs can quickly get out of control, despite the low purchase price. It is therefore advisable to switch off the heater during the day.
How high are the electricity costs of a heating mat?
Thanks to an integrated thermometer, the heating mat only heats up when the temperature falls below a predefined level. This considerably reduces electricity costs.
Normal heating mats, on the other hand, heat permanently. This increases electricity costs many times over. One solution to this is timers. These can switch the heating mat on or off at certain times.
Decision: What types of heating mats are there and which is the right one for you?
Basically, heating mats can be divided into three categories
- Heating mat
- Heating mat with thermometer
- Heating mat with thermometer and soil sensor
The different types of heating mats each have advantages and disadvantages. Depending on the purpose for which a heating mat is needed, a different one is suitable for you. The following section explains the differences, advantages and disadvantages.
What distinguishes a heating mat and what are its advantages and disadvantages?
A cheap heating mat heats your plants continuously up to 35°C, so that they are always supplied with a constant temperature. No other settings can be made, which means that accessories are needed for use outside.
What distinguishes a heating mat with a thermometer and what are its advantages and disadvantages?
A heating mat with a thermometer is so practical because it measures the outside temperature and can therefore regulate the temperature of the heating mat perfectly. At night, when it gets cooler, the heating mat switches on and regulates the temperature so that the plants do not freeze to death.
What are the advantages and disadvantages of a heating mat with thermometer and soil sensor?
A heating mat with thermometer and floor sensor has all the advantages that a heating mat with thermometer already has. In addition, certain soil sensors provide the perfect temperature for each seedling.
These only need to be inserted into the soil near the plant so that they can measure the temperature at the root. This ensures the perfect temperature for each plant.
Buying criteria: You can use these factors to compare and evaluate heating mats
In the following, we will show you which aspects you can use to decide between the many possible heating mats. The criteria you can use to compare the heating mats with each other include:
- Place of use
- Power consumption
- Maintenance/maintenance effort
In the following paragraphs, we will explain what is important in the individual criteria.
Where should a heating mat be installed? Should it be installed on the windowsill or is it needed in the greenhouse? These are crucial questions you need to ask yourself in order to find the right heating mat.
The location will determine how much power is needed to heat the plants sufficiently. If you are planning to place a heat mat on a stone windowsill, a higher output will be required as stone slabs take a long time to store heat. If a heat mat is needed in a greenhouse, a lower wattage is suitable for sufficient temperature.
The installation of a heating mat is simple and usually takes little time, so that it can be installed in a few seconds. All you have to do is unroll the heating mat and place it on the surface to be heated. After that, the flower pots or seedlings can be placed on it. Now you only have to connect the heating mat to the electricity and you are ready.
Heating mats can take 30 minutes to warm up!
However, if a proper floor heating system is needed for your greenhouse, this can take time and effort. Often heating cables need to be laid and buried. In addition, soil sensors need to be installed so that the perfect soil temperature always prevails. For most people, however, the simple option will be enough to make your plants grow taller.
Many manufacturers only offer the legal 30-day guarantee. However, there are certain manufacturers who voluntarily extend their warranty. Bio Green is one of these companies. Generally, this manufacturer offers a 1-year warranty on its products. However, selected products may include up to 5 years warranty.
Our heating mat therefore has a 3-year guarantee, which sets it apart from other heating mats. Bio Green also offers various other heating options for your greenhouse with an extended warranty. This means you are always covered against damage.
The power consumption of a heating mat plays a major role. The most important factor is the power of the heating mat. The higher the power, the more expensive the electricity bill. We recommend a heating mat that is controlled by the temperature.
This has the advantage that the heating mat only switches on when the set temperature is reached. This saves considerable electricity costs. However, they usually cost more than twice as much. A timer also serves its purpose here.
It only needs to be set so that it comes on in the evening and switches off again in the morning. With this version, the plants cannot expect any additional heat in the event of a sudden temperature drop, unlike a heating mat with a thermometer.
This means that you always have to keep an eye on the outside temperature so that your plants can grow without any problems. However, if you install the heating mat indoors, this is not necessary and fixed heating times can be set without any problems.
As heating mats are waterproof, they can be cleaned with water without any problems. A heating mat does not require any additional maintenance.
