Installing a tankless water heater can completely transform the way your household uses hot water. Designed for energy efficiency, convenience, and compact living, tankless systems are gaining popularity across Europe. Eccotemp’s Smart Home water heaters are a particularly great fit for European homes, offering reliable performance with modern, eco-friendly features.
Whether you're updating an existing water heating setup or planning for a new build, knowing how to install a tankless water heater in Europe correctly is essential. In this guide, we’ll walk through the complete installation process for Eccotemp’s Smart Home Tankless water heaters—highlighting tips specific to European homes and safety regulations.
Choosing the Right Eccotemp Water Heater for Your European Home
Before starting the installation, it’s important to choose a model that suits your household’s needs. Eccotemp offers the Smart Home Liquid Propane tankless water heaters built for European voltage (230V), CE compliance, and modern lifestyles. This water heater is designed for flexibility—whether you're living in a small apartment, rural cottage, or coastal retreat.
When selecting your water heater, consider your daily hot water usage, number of bathrooms, and desired temperature settings. Smaller homes or flats may only require a lower flow rate, while larger families might benefit from a more powerful option.
Keep in mind that Eccotemp’s Smart Home tankless water heaters are exclusively powered by Liquid Propane. Before purchase and installation, confirm that you have access to a stable propane supply and the appropriate regulator for your country.
Preparing the Installation Area
Installation begins with identifying a proper location. For indoor installations, the area should be dry, secure, and meet safety requirements.
Indoor installations require well-ventilated spaces to safely expel exhaust gases. Your water heater should be placed close to existing water lines and near an electrical outlet. This reduces the need for additional wiring or plumbing rerouting, which can save time and cost.
Avoid placing the heater in enclosed spaces without ventilation, or next to flammable materials. Also, ensure it’s easily accessible for routine maintenance or inspections.
Tools and Materials You’ll Need
Proper preparation makes the installation smoother. Gather these tools and supplies in advance:
- Power drill with masonry or standard bits
- Wall anchors and screws for mounting
- Pipe thread seal tape or compound (approved for gas and water lines)
- Flexible stainless steel hoses for hot and cold water connections
- Shut-off valves for both water lines
- Voltage tester for checking electrical current
- Gas leak detection spray or soapy water solution
- Adjustable wrench and screwdriver
- Descaling solution or kit (for hard water areas)
- Stainless steel flue or vent pipe (for indoor models)
- Having everything ready before beginning the installation avoids delays and reduces the risk of errors.
Step-by-Step Installation Guide
Turn Off Power and Water
Safety comes first. Before doing any work, switch off the main power supply to the area and shut off the water. This prevents accidental shocks or leaks during installation.
Mount the Heater
Secure the heater using strong screws and wall anchors. Ensure its level and tightly fastened, especially if mounting onto brick or stone walls commonly found in European homes.
Proper mounting prevents vibration or movement during operation and supports stable plumbing connections.
Connect the Water Supply
Attach the cold-water line to the inlet and the hot water line to the outlet using flexible hoses. Installing shut-off valves on both sides is recommended, as it makes future maintenance easier. Make sure all fittings are sealed tightly with thread tape or compound.
If you live in a region with hard water, consider installing a sediment filter or water softener to reduce scale buildup over time. This helps preserve your heater’s efficiency and extends its lifespan.
Flush the Water System
Before connecting the gas line, turn on the cold-water valve and run water through the system for a few minutes. This flushes out any debris from the new plumbing and helps prevent clogging or internal damage to the heater.
After flushing, shut off the water again to proceed with gas connection.
Installing the Liquid Propane Line
Connecting the propane supply is one of the most important steps. Use a certified regulator appropriate for your local propane system. Connect the line to the heater using approved flexible gas tubing or rigid piping as per local codes.
Check that all fittings are properly sealed. Once the line is connected, use gas leak detection spray or a soap-and-water solution to test for leaks. If bubbles appear, tighten the fittings and test again. Do not use an open flame for leak testing under any circumstances.
Once you’re confident the connection is secure, proceed to power up the system.
Ventilation Requirements for Indoor Installations
Eccotemp Smart Home water heaters must be vented properly to exhaust combustion gases. Use only the venting accessories recommended by the manufacturer to avoid compatibility issues.
The vent pipe should lead directly outside, minimizing bends or sharp turns. Seal the wall opening where the pipe exits to prevent drafts, insects, or water intrusion. Ensure that the exterior exhaust port is unobstructed and not placed near windows, doors, or fresh air intakes.
Ventilation is vital not just for performance, but also for safety. Improper venting can lead to carbon monoxide buildup, which poses serious health risks.
Electrical Connection and Setup
Plug the heater into a grounded 230V outlet. Avoid using extension cords or multi-plug adapters. If necessary, have an electrician install a dedicated outlet near the heater.
Once powered, the digital control panel will light up. Use the interface to set your preferred hot water temperature—typically between 37°C and 50°C. Error code displays for diagnostics and support smart Wi-Fi features for mobile control.
This water heater includes app connectivity, follow the instructions to pair it with your smartphone for remote temperature adjustments and monitoring.
Initial Test and Final Checks
To ensure everything works properly:
- Turn on the cold water valve and open a hot water tap inside the home.
- The heater should ignite automatically and begin producing hot water.
- Monitor the digital screen for water temperature and check that the flow remains steady.
- Listen for any unusual noises and inspect for leaks at all connection points.
- If any errors appear on the screen, refer to the user manual for troubleshooting steps.
- Once everything checks out, your tankless water heater is ready for daily use.
Local Regulations and Installer Requirements in Europe
Installation of a tankless water heater in Europe must follow local codes related to gas, plumbing, and electrical systems. Some countries or municipalities may require certified professionals to handle gas lines or power connections.
Consult local building authorities or a licensed technician before beginning installation. Not only does this ensure compliance, but it also protects your warranty and liability in case of damage or mishap.
Eccotemp tankless water heaters are CE-certified, making them legal to install across the EU. However, individual requirements—such as ventilation rules or propane tank distances—can vary by region.
Ongoing Maintenance and Care
Regular maintenance helps keep your heater operating efficiently and safely. In areas with hard water, flush the system every 6 to 12 months using a descaling kit to remove mineral buildup. Check filters and clean them regularly to prevent clogging.
Inspect gas and water connections yearly for signs of wear or leakage. Keeping a regular maintenance routine ensures your water heater performs at its best for years to come.
