As winter approaches, most of us feel the same way:
- Going into the bathroom feels like jumping into ice-cold water.
- As soon as the gas bill arrives, you just want to curse.
- The environmental agency or neighbors seem to constantly monitor the exhaust pipe.
- The apartment is small – and the tankless water heater still needs to fit into the kitchen cabinet somehow.
Don't worry! This time, the new ThermoMate 12 L Gas Tankless Water Heater for indoor use understands your needs exactly. It provides continuous comfortable hot water and uses intelligent technology to reduce energy costs and environmental impact.
Goodbye, high bills: Exclusive ECO energy-saving mode
Energy costs are among the biggest expenses for European households – and ThermoMate was designed precisely for this: efficiency is the top priority.
Switch to ECO mode and you'll immediately consume 17% less gas compared to standard mode.
Based on the projected natural gas price in Germany for 2025 (approx. €0.08–0.12/kWh), a family of four can save €120–200 per year on hot water alone – enough for several crates of beer or even a weekend trip to Bruges!
In the warmer months, when you don't need very hot water, ECO mode is the most economical and environmentally friendly way to operate the heater.
Compliance & Sustainability: Low-NOx Technology & ErP Certification
-
Ultra-low emissions: Advanced Low-NOx technology significantly reduces harmful gas emissions and minimizes your household's ecological footprint.
-
ErP certified for indoor use: Fully compliant with the strict EU Directive for energy-related products (ErP). Thanks to the special indoor gas tankless water heater, it can be safely installed in kitchens, utility rooms or other indoor spaces.
12 L Capacity: The Ideal Hot Water Solution for German Households
The GZ318 was specifically designed for the typical hot water usage patterns of European families: steady, reliable hot water.
In the cold winter months, everyone wants to enjoy a comfortable 10–15 minute shower. A 12 L system easily supports a shower and a kitchen faucet simultaneously, without sudden temperature fluctuations.
The integrated intelligent thermostat ensures a constant water temperature, regardless of whether neighbors suddenly use water or the flow rate changes. This way, you enjoy consistent comfort with every shower.
Winter Protection: Four-stage Frost Protection for European Climates
Considering the winter temperatures in Central and Northern Europe, the ThermoMate GZ318 features four-stage frost protection technology. Automatic frost protection is activated immediately upon plugging in the device and operates at temperatures below 5°C.
It also features:
-
Gas leak alarm
-
Overheat protection

Exhaust gas backflow protection

LED display for easy temperature setting
All designed to keep you safe all winter long.

Water and gas connections use G 1/2" and are compatible with most standard fittings on the market.
