There could be several reasons for this issue. First, check if the gas valve supplying the heater is open. Also, verify that the gas pressure is within the specified range. Additionally, ensure that the water flow rate is adequate, as insufficient flow can prevent the heater from generating hot water.
To adjust the temperature, locate the temperature control knob on the front panel of the heater. Turn it to increase or decrease the temperature setting as desired. Remember, a hot water temperature above 60 degrees Celsius may pose a risk of scalding.
Unusual noises may indicate a potential problem. Check if the heater is properly vented and the flue gas exhaust is unobstructed. Additionally, make sure that there are no loose or damaged parts within the heater. If the noise persists, it is advisable to contact a professional technician for further inspection.
Regular maintenance is essential to ensure optimal performance and longevity of your water heater. It is recommended to have a professional inspect and service the unit annually. This includes checking for any gas leaks, cleaning the burner, descaling the heat exchanger, and verifying proper functioning of all components.
If the heater fails to ignite, check if the gas supply is turned on and the gas pressure is sufficient. Make sure the pilot burner and flame sensor are clean and free from any dirt or debris. Additionally, ensure that the electrical connections are secure and there are no issues with the ignition system. If the problem persists, it is advisable to seek assistance from a qualified technician.

Based on the information in the manual for the Cointra Optima COB-10 b water heater, the safety element called T.T.B. is responsible for ensuring the proper evacuation of combustion products. If there are disturbances in the evacuation, the T.T.B. device will interrupt the gas supply to the burner. To address the issue of the water heaters not firing up, you can follow these steps: 1. Check the evacuation of combustion products by examining the burnt gas outlet. 2. If the T.T.B. device is activated when you turn on the water heater, it indicates a problem with the evacuation. In such cases, it is recommended to revise the evacuation system and ensure it is functioning properly. 3. If there is damage to the T.T.B. device, it is important to use only original spare parts for replacement to ensure proper functioning. 4. If necessary, the T.T.B. device should be replaced by experts. Please note that these instructions are general and may vary depending on the specific model of the water heater. If you have any further questions or need assistance, please let me know.

Hi my boiler is having problems lighting when it does there is hot water instantly when it doesn't it just clicks away try to light.
The gas valve fails to open
Threes tap heat up ,but one in kitchen does not.
My boiler is very intermittent with the hot water. It starts off good then gets too hot. When I turn the tap slightly for cold water the boiler cuts out.
My Cointra COB 10 water heater has good water and gas pressure, but only supplies warm water. The propane bottles are new.
The heater is lighting ok and going to main flame but the water is only getting warm not hot.
