Frequently Asked Questions - TNC-150 H COINTRA
How do I install the Cointra TNC-150 H water heater?
Installation must be performed by a qualified technician. The unit should be mounted horizontally on a wall capable of supporting its full weight (about 197 kg when filled). Connect the inlet and outlet pipes, install the supplied safety valve, and plug into a grounded outlet. Follow the manual's steps carefully.
What is the maximum hot water temperature?
The thermostat allows you to adjust the temperature up to a maximum of 75 °C. For optimal comfort and energy saving, a setting around 60 °C is recommended.
How long does it take to heat the full 150-liter tank?
With a 2000 W heating element, the water heater can heat a full tank from 15 °C to 60 °C in approximately 3.5 to 4 hours, depending on the incoming water temperature.
How do I drain the water heater for maintenance or winter storage?
Turn off the power and close the cold water inlet valve. Open a warm water tap to vent pressure, then connect a hose to the drain valve at the bottom. Open the valve and let the water flow out completely.
What maintenance does the TNC-150 H require?
Regular maintenance includes replacing the magnesium anode every 12-18 months to prevent corrosion, descaling the heating element if you live in a hard-water area, and periodically testing the safety relief valve.
Why is the safety valve on my heater leaking water?
A small amount of drip can occur when the tank is heating and the pressure exceeds the threshold (normally 8 bar). If leakage is continuous, the valve may be faulty or the inlet pressure is too high. Check with a pressure gauge and replace the valve if needed.
How can I reduce energy consumption?
Set the thermostat to 60 °C instead of 75 °C, insulate exposed hot water pipes, use the heater during off-peak hours if your tariff allows, and avoid leaving it on when no hot water is needed for extended periods.
What does the 'H' in TNC-150 H stand for?
The H indicates a horizontal installation model, meaning the tank is mounted in a horizontal position. This is ideal for spaces where height is limited.
Can the TNC-150 H be connected to a solar heating system?
No, this model is designed as a standalone electric water heater. It does not have ports or controls for solar thermal integration, so using it with solar panels would require additional external equipment and professional adaptation.
Which spare parts are commonly available for this water heater?
Recommended spares include the thermostat, heating element, magnesium anode, safety valve, and gaskets. These are widely available from authorized Cointra distributors and online spare-part shops.
