FAQ – Find the right accessories

The products are heated using power from the rechargeable lithium-ion battery. The heat is generated by the sewn-in carbon fiber threads located in the heating zones and can be easily adjusted using the button to three different levels: high, medium, and low.

The Base Layer V7 + V8 comes with an XL battery of 5,000 mAh for each part. It is charged via a USB-C charger, which is not included. The battery can also be charged with a 5V power bank, as there is a built-in ‘step-up’ in the battery that converts 5V to 8.4V. The Base Layer (under Outlet) comes with a 2,600 mAh battery and charger, unless you have opted out of this during the purchase process. Here, you can choose the new XL battery with dongle (conversion cable) instead. For the soles, you can choose to use regular 5V power banks or our combined hand warmer/ power bank with 5,000 mAh or 10,000 mAh, respectively, which also has an (important) on/off function so you don't have to plug it in/out every time you want to turn the heat in the soles on/off. 5000mAh provides approx. 5 hours of constant heat on a single charge – 10000mAh = 10 hours.

The 2600mAh battery for the garment is 7.4V (and requires 8.4V to charge), so it cannot be charged with a 5V USB charger. The XL battery for Base Layer V8 and V7 can be charged with a USB charger or a power bank, as there is a built-in ‘step-up’ in the battery that converts 5V to 8.4V. So now you can charge the large battery on the go!

Each product has recommended heating times for the batteries.
Depending on the heat level selected, the following recommended times apply to clothing (to make it easy to remember): 2600 mAh: Red = 2 hours - Yellow = 4 hours - Green = 6 hours. 5000 mAh (new XL battery): Red = 4 hours - Yellow = 8 hours - Green = 11 hours Heavy-duty gloves, mittens, jackets, vests, etc. last a little longer than the recommended times, so add about +10%. It is also important to note that the battery's full capacity is only achieved after 8-10 full charges and discharges. If you start using your clothing and find that the battery does not quite live up to the recommended heating times, this may be due to a battery that is still ‘young’. The accompanying battery instructions should always be followed.

'Warm hand in a warm glove'.
In general, make sure to turn on the heat before you get cold. This is important, as the technology is designed to keep you warm, not necessarily to heat you up. Therefore, you may find that you don't get very warm, but on the other hand, you won't freeze either – only when the heat is turned off.

Please note that the underwear, which is close to the body, becomes very warm at the highest heat setting (Red). This setting is only intended to provide a “burst” of heat here and now (we recommend a maximum of 10 minutes at a time on RED), after which you should turn it down to medium (Yellow) or low (Green). This will also make the battery last longer on a single charge.

The clothing is sewn to a very high standard, but must of course be used with care, as it contains built-in wires and cables/electronics. Therefore, avoid pulling, stretching, and tearing the products when putting them on and taking them off. In particular, avoid pulling too hard on the right sleeve of the undershirt, as the wires for the control button are connected here. Take an extra 10-15 seconds when dressing and undressing, and your product will last for many years.

On Base Layer V7, the control button sits next to the battery pocket, and on the new Base Layer V8 it sits on the breastbone – both for greater comfort and durability during use.

We also recommend washing the clothing in a laundry bag.

Yes, the clothes can be washed in a laundry bag at 30°C on a gentle cycle, as long as you remember to remove the battery and make sure that the cord is tucked away securely in the battery pocket (closed/zipped).

Hang to dry afterwards.

The control button briefly lights up red when the battery is connected to indicate that contact has been established. The garment is then turned on and off by holding the control button down lightly for 2-3 seconds.

See the section below for more questions and answers about batteries, connectors, and chargers.

No, all our products use 7.4V or 12V, which is low voltage, so you cannot get an electric shock.

xYes, as all our products are low voltage, they will not affect your pacemaker.

We have spoken to the manufacturers and conducted tests over a 7-year period, so there is no need to worry.

Exchange - If you would like to exchange for a different size or color of the same product, simply send the unused item in its original packaging, without the charger and battery, directly to us (and never to the delivery point) at:

Yes, in principle it is possible (but only if used incorrectly).

The underwear fits snugly and can become very hot (54°C*) at the highest temperature setting (Red). If the body cannot absorb any more heat in the blood and nerve pathways, the heat is “rejected” by the body and the skin remains at 54C - this can cause red marks.

If you experience discomfort in the form of “tingling or prickling” or similar, it is of course important to turn down the heat immediately.

We recommend a maximum of 10 minutes at the highest setting, RED, at a time!

We do not recommend that the underwear be used by children, disabled persons, or persons with reduced sensitivity without supervision.

You can pay with all major credit and debit cards, including VISA and Mastercard.

You can also make a bank transfer.

There may be something to it, as we have received a lot of positive feedback on this. The clothing has a very positive effect on your well-being and can prevent muscle tension, pain, colds, relieve old injuries, arthritis, etc.

Infrared rays are a form of electromagnetic radiation that lies just outside the visible light range of the electromagnetic spectrum. These rays have longer wavelengths than visible light and are known for their warming effect. When infrared rays hit the body, they are absorbed by the skin and tissue, which converts the energy into heat. This process can increase blood circulation and stimulate sweat production, which can have several positive effects on the body.

Infrared heat treatment increases blood circulation and thus the oxygen supply to any damaged tissue. This has an impact on, for example, chronic joint pain, muscle pain, and sports injuries. Infrared heat treatment promotes relaxation and comfort and has a healthy influence on sleep quality and stress.

Studies also show a significant reduction in high blood pressure, improvement in blood viscosity, and a healthy effect on heart function.

International studies have shown that treating asthma, bronchitis, colds, flu, sinusitis, and constipation with FIR infrared therapy has a beneficial effect. The treatment reduces inflammation and swelling, including of the mucous membranes.

No, it cannot.

The garment has a built-in overheating protection (mechanical TPC) that automatically turns off the heat if the temperature exceeds 55°C.

In addition, there is a safety circuit in the battery that also shuts off if there is a voltage surge in the garment.

When the skin has warmed up and can no longer absorb any more heat, it is important to turn down the highest temperature setting (red), as otherwise you risk getting red marks. Keeping 55°C directly on the skin for a long time can have consequences, and we therefore do not recommend that the clothing be used by children, disabled persons, or persons with reduced sensitivity without supervision.

Yes, no more cold feet.

We have both heated insoles and heated socks that are powered by a power bank (5V) and attached to a strap around the lower leg or via an extension cord in your pants pocket. The insoles are only 3 mm thick and can be cut to your size (in the heel on version III) to fit your shoes. The orange side should face up.

The heat settings are ON/OFF.

All our products are sized according to Scandinavian standards, so if you wear size M, you should also choose size M here. However, women should choose one size smaller in underwear than they usually do (as the sizes are men's sizes).

E.g. women's size 38/M = choose size 36/S. If you are between two sizes in underwear, always choose the larger size to avoid any strain on the ligaments.

If you are between two sizes in underwear, always choose the larger size to avoid possible strain injuries to the wiring. If you are in doubt about sizes, please feel free to call or write to us at tel. +45 2717 0000 - Service@NordicHeat.dk

Yes, Danish weather is notoriously changeable, so this garment is extremely versatile all year round.

Many people wear the vest indoors on a cold evening or on a cool summer evening on the terrace, for example.
