Vitowell comfort Deluxe: Maximum efficiency and intelligent control

Individually controllable, highly precise and efficient: those who make no compromises for their family choose a Vitowell comfort Deluxe water heater. With digital display functionalities, it provides maximum control over the heating status and allows substantial energy savings thanks to the water availability programming function. An electronic timer is not only convenient to assure that the heater will automatically switch on/off; it also helps to use the device in the most efficient way.

Ceratech Technology®

Viessmann adopts the exclusive Ceratech Technology® enamel coating formula to extend the durability of its water tanks. The anti-corrosion function performed by the internal water tank ceramic layer has been developed with decades of expertise and continuous improvement of materials and applied technology. The ceramic layer has a particularly high density and a perfectly smooth surface, undergoing a 100% quality check off the production line. Acid corrosion resistance, alkaline resistance, temperature and pressure resistance - all these technical characteristics are in line with the latest German quality standards to guarantee a long-lasting durability of the heater at its core. 

Intelligent control

The Vitowell comfort Deluxe provides maximum control over the heating status and substantial energy savings thanks to various functions. With its digital soft touch display, it allows for precise temperature setting. The electronic timer mode allows programming of up to 2 daily heater-activation periods. During this period, stored water will be checked and heated up to the desired temperature whenever necessary. You can set two daily shower times, and the heater will automaticallyswitch on/off to complete the heating process at the desired time.

Flexible energy consumption

The Vitowell comfort Deluxe heater strikes with flexible options for energy efficiency: Electronic programming enables reduced energy consumption with convenient pre-set of hot water availability at 2 daily heater-activation periods. You also have further flexibility to decide between dual power options, providing more flexibility in the use of electric power. The double-power option has been integrated as a push-button choice for either fast water heating mode or slower, energy-saving heating mode.

The temperature LED ring also provides greater clarity on heating status / hot water availability and precision temperature control: orange light is an indication of ongoing heating progress while blue indicates the hot water is ready.

Durability taken to the next level

Deluxe heaters are not only equipped with a ceramic coating on the water tank surface, but also on the heating element. This additional protection to the heating element and tank makes both more corrosion resistant, and also maintain high heating efficiency of the heating element. The heater also has a thick PU insulation layer engineered for very long heat preservation even after heater turned off, making it energy saving and extended showering comfort.

FAQ on storage water heaters

A power trip at home caused by the turning on of the electric water heater is usually related to electrical wiring/ electrical supply problems that fall under these common causes:

  • Wrong wiring connection, or worn/damaged cables that has fused or come into contact with each other, leading to a short circuit
  • Failure to wire to a dedicated water heater power point/ front flex outlet. A 3-pin socket outlet should not be used because its power rating is insufficient to support water heater.
  • Sharing of the power point/socket with other electrical appliance(s) resulting in electrical overload. The power point for water heater should never be shared.
  • Faulty heater switch / power point.

Please consult a Licensed Electrician to check and rectify any electrical problem. If the power trip persists even after an electrical inspection, kindly contact Viessmann Service Support to check and service your water heater unit.

Before turning on the electrical supply, turn on the water supply to ensure that your storage water heater is completely filled up with water. This is an important step to avoid dryburn and damage to the thermal components such as thermostat and heating element.

Make sure that the water inlet and outlet have been connected correctly, otherwise colder water in the storage tank will be dispensed first. The red and blue rings on the underside of the Viessmann storage water heater indicate the hot water outlet and cold water inlet respectively.

If the above conditions have been fulfilled and your water heater is still not working, please contact Viessmann Service Support to check and service on the water heater unit.

There are 2 common reasons why the water from your storage heater is not hot enough:

  • Water not fully heated up yet: give some time for the water to be heated up before use.
  • Water flow rate at water fixture is too high: hot water stored at the heater is being consumed faster than the rate at which the cold water refilled into the tank can be fully heated up. In such a situation, turn on the water fixture tap partially instead, or install a flow restrictor to reduce the water flow.

Use the light indicators on Viessmann storage water heaters to easily recognise whether the heating process is completed.

Under Singapore regulation SS636:2018, pressure relief valve is necessary to be installed at the cold water inlet of the storage water heater to prevent tank overpressure, leakage, or explosion in worst case. You can find a pressure relief valve included in the accessory pack of every Viessmann storage water heater unit supplied.

Whenever the water pressure at the water heater is too high, the pressure relief valve will release excess pressure through releasing/dripping of water. This releasing/dripping of water will stop when the water pressure is reduced and stabilized.

To check if releasing/dripping of water arise from the normal operation of the pressure relief valve, you can simply turn on water at the shower for 20-30 sec, and observe if the drip at the pressure relief valve stops.

If water dripping occurs permanently, kindly contact Viessmann Service Support to check and rectify on the possible faulty pressure relief valve.

To ensure the best performance from this appliance, it is recommended to replace the magnesium anode, flush out any deposit of salts in the heater tank and descale the heating element once every two years. The maintenance cycle may vary depending on the water quality. It is best to engage a Licensed Plumber or service technician to perform the maintenance operation.
