Frequently Asked Questions About Grünwelt Heat and Power

From switching providers to meter readings

Questions about heat flow rates

With Grünwelt Wärmestrom’s affordable rates, customers with night storage heaters and heat pumps can now save money too. Since you use electricity in the evening and at night, the price during this time frame is significantly lower. Because we always work efficiently and cost-consciously in our customers’ best interests, we can pass on additional savings to you and offer you a consistently affordable heating electricity rate. At the same time, you receive 100% sustainable green electricity from us, thereby making a valuable contribution to environmental protection.

All customers with off-peak storage heating or a heat pump can switch to Grünwelt Wärmestrom’s low-cost rates. Your annual electricity consumption must not exceed 100,000 kWh. All you need is your meter number and the customer number from your current provider. You can usually find this information on your most recent annual bill.

A night storage heater is an electrically powered heating system that generates heat using electricity. Electricity is used at specific times (usually at night) to heat the storage unit and then gradually release the heat. The consumption of a night storage heater is measured by a special meter. This meter measures normal household electricity consumption during the day (“peak-rate time window”) as well as heat consumption at night (“off-peak time window”).

A heat pump is a technical device that uses electrical energy to extract stored heat from the ground, water, or air and release it into the home as heat. The principle is similar to that of a refrigerator, but works in reverse. A heat pump also uses a refrigerant, but one that generates heat instead of cold. After the heat has been released into the home, the refrigerant cools down again and the cycle in the heat pump starts over.

There are three common types of meters used for measuring heat flow:

Combined dual-rate meter (high/low) with residential electricity: In this setup, there is only one meter for the entire household, which internally features two separate meter units. These sub-meters record electricity consumption during the day (in the so-called high-tariff time window) and at night for heating electricity consumption (low-tariff time window). When switching to Grünwelt heating electricity, you provide the meter number of this meter, and we will supply you with both household electricity and heating electricity.

Separate single-rate meter for heating electricity only: In this setup, the household has a separate meter for household electricity consumption and a separate single-rate meter for heating electricity consumption. When switching to Grünwelt heating electricity, you only need to provide the meter number of the separate heating electricity meter, as the separately metered household electricity is not included in the supply.

Separate dual-rate meter for heating electricity only: In this setup, the household has a separate meter for household electricity consumption and a separate dual-rate meter for heating electricity consumption. When switching to Grünwelt heating electricity, please provide only the meter number of the separate heating electricity meter, as the separately metered household electricity is not included in the supply.

If you have a separate meter for household electricity and a separate meter for heating electricity, this is referred to as “separate metering,” since each meter has its own electricity supply with a separate contract. In this case, if you switch to Grünwelt for heating electricity, we will only bill you for your heating electricity consumption. For your household electricity, you can sign a separate contract with us on our website under the “Electricity” section.

If you have a single meter (a dual-rate meter) that measures both your household electricity and heating electricity consumption together, this is referred to as “combined metering.” In this case, household electricity is shown on your meter as the so-called HT portion (“high tariff”), and your heating electricity is shown via the NT portion (“low tariff”). By switching to Grünwelt heating electricity, we will then bill both household electricity and heating electricity under a single contract. Different rates apply to household and heating electricity consumption, which will be displayed to you as part of your order.

If you have a separate meter for your household electricity, we do not supply that meter under the heating electricity plan. We would be happy to supply your household electricity meter with one of our affordable Grünwelt electricity plans. Since a separate meter requires a separate contract, you will need to sign up for a new plan. On our website, you can choose from a wide range of plans for your household electricity.

Your switch to Grünwelt Energie

By switching to an electricity plan from Grünwelt Energie, you’ll enjoy multiple benefits: Thanks to our lean organizational structure, we offer affordable rates and provide you with 100% sustainable green electricity—certified by TÜV NORD—generated from European hydropower. This is good for the environment and easy on your wallet at the same time. Of course, we don’t skimp on service—our friendly customer service representatives are here to assist you with advice and support for all your energy supply needs.

Any electricity customer with their own meter can switch to us conveniently and securely. To do so, first enter your ZIP code and your electricity usage into our rate calculator, and you’ll receive a no-obligation price quote. Then simply click the “Order” button, and we’ll guide you step by step through the ordering process—via an encrypted connection, of course. At the end, you’ll receive an order confirmation that you can print out for your records. Just a few days later, you’ll receive your contract confirmation from us. In the meantime, we’ll take care of all the formalities. If necessary, we’ll cancel your old electricity contract and switch you over to our affordable rates exactly on the delivery date, without any interruption to your power supply.

If you rent an apartment with its own electricity meter, you can easily switch to us. The same applies if you rent a house. If you live in an apartment building and do not have your own electricity meter, you should discuss switching to us with your landlord or property management company, as the meter may be shared among several residents.

To switch electricity providers, you will need your electricity meter number, your electricity usage for the past year, and your customer number from your current provider. You can usually find all this information on your most recent electricity bill. We also need your billing address for your order, as well as a direct debit authorization or a SEPA mandate if required. All data is transmitted via an encrypted connection and handled in accordance with the provisions of the Federal Data Protection Act.

You generally do not need to cancel your existing electricity contract yourself, as you can grant us power of attorney to do so as part of your order. We will then cancel your old electricity contract on your behalf in time for the start of service and handle all the necessary paperwork. The only exception: If you wish to switch to us due to a price adjustment or another short-notice termination option, you should cancel your contract yourself due to the tight timeline. In this case, please let us know the end date of your contract when placing your order.

No, no additional contracts are required; by placing your order with us, you have already taken care of everything necessary.

No, of course there are no fees for switching to us.

If you are already a Grünwelt Energie customer and would like to place another order, please give us a call—our friendly service experts will be happy to work with you to explore the options available for your contract. You can reach our customer service team using the contact information provided.

Delivery date: How long will the switch take?

There are legally mandated timeframes for switching electricity providers that all suppliers must adhere to. Unless your current contract specifies longer notice periods, it takes us about four weeks from the time you place your order until service begins. Shortly after you place your order, we will send you a contract confirmation with an estimated start date for service. We will then cancel your old electricity supply contract and register your supply point with the relevant grid operator. Both your previous supplier and the grid operator must confirm these steps to us. Once we have the green light from both, we will immediately inform you of the good news with a supply confirmation.

We do our very best to meet your requested delivery date. However, in order to switch providers, we also need to coordinate with your current provider and the local network operator. If any issues arise, we will of course notify you immediately and work to find a solution right away so that we can get you connected as soon as possible.

Yes, even if your old contract still has some time left on it, you’re welcome to place an order with us in advance. The remaining term of your old contract can be up to 12 months.

Yes, if you exercise your right to terminate the contract early, you can let us know the contract end date when you place your order. We will then schedule your delivery accordingly.

Your utility provider will contact you to obtain your meter readings at the start and end of your electricity service. We recommend that you always provide your meter readings to your utility provider as well and make a note of them for your records.

No, due to legal regulations, it is impossible for your electricity supply to be interrupted when you switch providers. The local backup provider ensures a continuous supply of electricity at all times—even if a problem were to arise.

Payment and Billing

Novalnet AG is a payment institution regulated by BaFin (the German Federal Financial Supervisory Authority) that we have engaged to optimize our processes. So please rest assured that payments are collected on our behalf by Novalnet AG. You can also find details such as the contract account number or Grünwelt Wärmestrom GmbH in the payment reference for the debit.
                                    

We first calculate your estimated bill for the coming year and then divide it into equal monthly installments so that the difference at the end of the billing period is as small as possible. You will find the exact amount and payment dates in your order confirmation. You can pay your installments via SEPA direct debit or bank transfer.

The base rate is a fixed annual fee included in your contract and is billed on a monthly basis. The usage rate is the variable charge per kilowatt-hour of electricity consumed.

The estimated bill amount for the coming year is divided into monthly installments so that the difference at the end of the billing year is as small as possible. To calculate this, your consumption is multiplied by the rate per kilowatt-hour, and the annual base fee is added. The result is then divided among the individual months to determine the monthly installment amount. Any new customer bonus that may have been agreed upon is not included in the monthly installments, as this will be paid out to you on the dates specified in the contract.

To calculate your estimated bill, we use your most recent known annual consumption. If you’d like to change your estimated bill amount during the year, you can request this from our customer service team when you submit a meter reading. If your annual consumption has changed, we’ll adjust your estimated billing plan accordingly.

After one year of service, we will first ask you to provide us with your meter reading. We will then use this reading, along with information from your local utility provider, to generate your consumption bill for the past year and send it to you.

Our affordable electricity rates are made up of a variety of price components. In addition to procurement and distribution costs, these include grid fees, government-mandated charges, and taxes and levies. You can view the price components in detail on our Electricity Price Information page.

For some plans, we offer a new customer bonus. This bonus may be provided as a percentage credit toward the total cost of electricity service during the first year of service or as a bank transfer a certain number of days after service begins. The specific terms and the amount of the bonus depend on your plan and are clearly outlined in your order form and contract confirmation.

If we have agreed to a limited price guarantee, we may not change prices during this period. Exceptions to this include changes to the EEG surcharge, the CHP surcharge, the surcharge under Section 19 of the StromNEV, the offshore liability surcharge, the surcharge for interruptible loads, the concession fee, and the electricity and sales taxes. Excluded are also price changes to the extent that new taxes, levies, or other government-imposed charges or exemptions affecting the procurement, generation, grid use (transmission and distribution), or consumption of electrical energy take effect in the future. Section 6 of our General Terms and Conditions applies to price changes.

Moving and Moving In

Please let us know about your move at least two weeks in advance, for example via our contact form. We would be happy to continue providing our services at your new address at our competitive rates. Please contact us by phone or email, and we will be happy to provide you with an attractive quote.

If you are the first occupant to move into a new property and would like to be supplied with electricity at Grünwelt’s competitive rates, you can still sign up retroactively up to 6 weeks after moving in. Otherwise, the local utility provider will supply your new home with electricity on a temporary basis until then. Please let us know your desired start date when placing your order.

When you move into an apartment, we will need information from you, including your planned move-in date and the meter number for that apartment. You can usually obtain this information by contacting your future landlord.

Technical Questions

A kilowatt-hour is a unit of energy. It refers to the amount of energy released or absorbed at a power of 1,000 watts per hour.

No, you do not need to make any changes to your electrical connection. You also do not need to replace the meter.

No, due to legal regulations, it is impossible for your electricity supply to be interrupted when you switch providers. The local backup provider ensures a continuous supply of electricity at all times—even if a problem should arise.

At the end of each billing year, we will ask you to take a reading of your meter and submit it online. In addition, the local utility may take readings.

In the event of power outages, your local utility company remains your point of contact, just as before. The utility is required to continue resolving these issues. We pay a usage fee for the operation and maintenance of meters and the power grid, which is already included in your bill.

All personal data we receive from you in connection with the electricity supply contract will be handled in strict compliance with applicable data protection laws. This means that we collect, process, and use your data exclusively for the purpose of fulfilling the contract and providing support and advice regarding your electricity supply from us. Grünwelt will not sell or otherwise market your data to third parties.

Our affordable electricity flows through the power grid to your home connection, just as it always has. We use the existing pipes and cables for this purpose, for which we pay a usage fee to the power grid operator. These fees are, of course, already included in your electricity bill.
