Questions & Answers

Shipping

When will my products be delivered?

We typically ship all products within 2-3 business days. Following that, your order will reach you within a few business days, depending on the delivery location. Any pre-orders or delays will be indicated in the description or in a separate message.

In which countries does 21energy ship to?

Currently, we ship to the EU, Switzerland, Norway, Great Britain, US & Canada. If you want to find out if we deliver to your address, you can easily test this in the checkout process by entering your address there.

What are the shipping costs for me?

The shipping costs vary depending on the delivery location. To calculate your personal shipping costs, you can go through the checkout process. After entering the delivery address, the costs will be displayed to you.
All orders over 200€ qualify for free shipping!

Are there any additional costs for customs or taxes?

For all customers within the EU, there are no additional costs due to taxes and customs. All customers outside the EU pay only the net price in the store when ordering. Therefore, taxes and duties will be incurred upon import and are to be paid there.

Can I cancel my order?

Yes, every customer has a 30-day right of withdrawal. Within this period, you can cancel your order without providing any reasons. The paid amount will be refunded to you via the originally selected payment method.

Income

How do the 21energy heaters and computers (mining devices) make money?

21energy heaters and computers (mining devices) generate revenue through the process of Bitcoin mining, wherein specialized hardware solves cryptographic puzzles to validate and secure transactions on the blockchain network. As a reward for their computational work, miners receive newly minted bitcoins and transaction fees.

How much can I earn from heating with the heaters or other mining devices?

Your mining earnings depend on various factors such as the price of Bitcoin, market rates for computations, global hashing power, duration of operation, and hardware model. For your individual situation, we have developed a profitability calculator. The significant distinction from any other electric heater is that cash flow is generated while heating.

Performance

Do the different products require more electricity than traditional heaters?

No, these products do not require more electricity than traditional heaters. They efficiently convert 100% of the electrical energy into heat, simultaneously utilizing it to mine Bitcoin, effectively leveraging energy in a dual capacity.

Does my electricity bill change with 21energy products?

If the same heating method (electric heating) with the same heat demand is applied as before, the electricity bill usually does not change, as the entire electrical energy continues to be converted into heat.

Can the heating power be adjusted on the individual devices?

The heating power can usually be adjusted continuously within a specific range on all of our devices.

How much heating area do 21energy products cover?

The heating area of each heater is specified in the product descriptions, which may vary significantly depending on their characteristics. For all individual hardware devices, the heating area can be determined using various calculators available online, based on the specified power output.

Are the products allowed to be overclocked to achieve maximum yield?

Our heaters are only allowed to be operated at the maximum power specified in the description and/or user manual. Overclocking poses a high risk and will void the warranty immediately. Similarly, each individual Bitcoin mining device should only be operated at its maximum standard power.

Safety & Warranty

Are the devices designed for maximum safety and CE compliant?

All products sold have been tested according to the highest and latest safety standards and are CE compliant.

Are safety mechanisms installed in the various devices to prevent overheating?

All our heaters are equipped with a special operating system designed to prevent overheating by shutting down the device beforehand.

Can 21energy products be operated around children?

Yes, our products are designed for use in residential spaces like traditional homes. They are conventional electrical appliances. Therefore, the usual precautions for children apply.

Is there a warranty on 21energy heaters and other products?

Provided that the safety precautions outlined in the user manual are followed, our heaters come with a 12-month warranty. This also applies to all of our newly and originally packaged Bitcoin miners.
