The 10 best tankless water heaters to buy in Germany
Finding the best tankless water heater system for your home can help save a lot of money in energy bills, although knowing what to look for in a heating system can be challenging for anyone that isn’t a plumber. Given the cost of paying for a new heating system, you will want to put a lot of thought and consideration into your decision, which is not always easy if you are unfamiliar with what a tankless water heater is and how to choose the right one for your home.
To help with this, we have created a handy buying guide that covers all the information that you need to know to find the best tankless water heaters for your home.
What are tankless water heaters?
As the name suggests, a tankless water heater is a type of water heating system that does not use a large water tank to store heated water. Instead, cold water passes through a pipe and into the heating unit, which uses either a gas burner or electric element to instantly heat the water. Whenever you turn on hot water, you instantly get a constant supply as there is no need to wait for a tank to fill with heated water. Therefore, a good tankless water heater makes hot water very convenient and energy-efficient.
Why should you buy a good tankless water heater?
One of the major benefits of using tankless water heaters is reduced energy consumption. Because there is no tank to fill and store with hot water, it can help to reduce water heating bills. Furthermore, while the initial cost of installation is higher than a tanked water heater, the best tankless water heaters are much more durable so will last significantly longer. This means you can save money over the long term, making it a fantastic investment for many homeowners.
How to choose the right tankless water heater in 2024?
Choosing a new tankless water heater can be daunting for those unfamiliar with water heating systems. So here are some things to consider that can make the process easier:
- Hot Water Consumption: You need to determine how much hot water you consume daily so that you can select a tankless water heater that meets the demand. Simply list all the fixtures in your home that use hot water at any time (e.g. faucet, shower head, dishwasher) and combine their flow rates. To check flow rate, simply refer to the manufacturer instructions for any fixture you’ve bought or check online for a rough estimate of each fixture.
- Temperature Rise: This refers to the temperature that the heater uses to warm incoming water to the desired temperature. To calculate, you need to determine the average temperature of incoming water and subtract from the desired incoming temperature.
- Power Source: A tankless water heater is either gas-powered or electric, so consider which is best for your needs. Electric is suitable for smaller water heaters designed for point of use (e.g. heating water for just the shower), while gas-powered water heaters are best for an entire household’s water heating.
What is the best kind of tankless water heater in Germany?
There are two main types of tankless water heaters available to buy:
- Gas-powered Tankless Water Heaters: Gas-powered systems are more powered and the most used, being the best tankless water heater for an entire household. However, you need to ensure that appropriate piping is in place and consider its location relative to where the heater will go, otherwise extensive installation work may be necessary.
- Electric Tankless Water Heaters: Electrically powered systems are only recommended for point of use rather than a whole household, as it puts too much strain on the electrical supply when forced to heat too much water. It is more affordable to install, however.
