Decentralized water heating?
- Heating exactly where it's needed
Water heaters are installed just where the hot water is required. Under the sink, at the wash basin, next to the shower or near the bath.
- Very little heat loss
Because the appliance is right next to the draw-off point, the pipes carrying the hot water are short. Energy-wasting distribution piping is avoided, bringing heat loss down to a minimum.
- Save water
Shorter pipes also mean that cold water does not first have to be drawn off at the outlet, so valuable water is not wasted
- Easy installation
STIEBEL ELTRON electric "point of use" water heaters are quick and easy to fit, even in a retrofit situation. This saves time and effort.
Electric "Point of Use" water heaters make full use of energy. They are a particularly economical way to supply hot water.
- Exact calculation
The precise individual calculation is very useful, especially in apartment buildings, as every single family will pay only for the warm water they actually consume. This is in fact an incentive to save energy and moreover, also prevents any quarrels and irritation when receiving an equally split bill.
Most instantaneous water heaters are pressure type units with pressure resistant copper or plastic tanks of 1000kPa (10Bar) pressure rating for a centrally installed hot water supply. Such a system can supply multiple outlet points depending on the amount of warm water (l/min), which is determined by the size of the element in kilowatts. These units are compact and have a large element, so water can be heated instantly and continuously.
The outlet temperature is affected by three different factors:
- Flow rate (l/min.)
- Cold water inlet temperature (C)
- Size of element (kW)
There are two types of units from STIEBEL ELTRON:
- Electronically controlled instantaneous water heaters
- Hydraulically controlled instantaneous water heaters
- Unit must be installed vertically only.
- When rotating the unit to connect the water connector at the bottom, the water inlet pipe should be on the right side of the unit.
- Release some water before connecting to the inlet to keep the inlet pipe filter clean.
- After installation the before switching on the electricity, open water valves to let water flow in until the pipe network and unit are free of air.
- The breaker must be the proper size e.g. for 6000-, 8000- or 12000-watt units, the breaker must be 30, 40 or 60 amps respectively.
- Switch on the electricity, open the cover and check the electricity at the terminal block. If no electricity, please check whether the breaker is on or off.
- If the breaker is on but unit still does not work, a reset may be needed. To do a reset, the breaker must be off, then open the cover and press the reset button at the thermostat.
(Please check with the manual to locate the thermostat button.)
- Cleaning the inlet filter often by first disconnecting from the cold water valve, then remove and clean the filter.
- A clean shower head filter will prevent low water volume.
- Low or variable water pressure can cause problems with hot and cold water coming out simultaneously, or the unit failes to work. In this case, the water pressure should be adjusted.
- Turning the water valve on to maximum can cause low water temperatures, due to rapid water flow in and out of the unit.
- For safety, please check and adjust the water temperature before use.
- If the water does not mix, please clean or remove the shower head filter.
