Small water heaters, wall and floor mounted cylinders
Small water heater
Small water heaters are powerful and compact domestic hot water appliances, representing an unobtrusive constant source of hot water. With a capacity of 5 to 15 litres, their cost-effectiveness is especially apparent when small amounts of water are required frequently. They are run from a standard 230 V socket. Thanks to the highly effective thermal insulation, hot water is available constantly, with minimum energy expenditure.Show all small water heaters
Sealed unvented small water heaters
Sealed unvented (pressure-tested) water heaters are not open to the atmosphere. For safety reasons, water will visibly drip from the safety valve of the safety assembly during heat-up.
Domestic hot water cylinders with a pressure-tested internal cylinder can supply several draw-off points. These appliances are available in sizes from 5 to 150 litres. They keep hot water available constantly at the required temperature of between 35 °C and 85 °C.
The thermal insulation between the internal tank and outer jacket meets the requirements for energy efficient operation. Generally, such appliances should be mounted on a wall near to the draw-off points used most frequently, to prevent unnecessary losses. As reheating a sizeable amount of water takes some time, match the appliance size to the maximum current demand. Depending on the appliance type, the internal tanks are made of steel with an enamel coating on the inside and feature an anti-corrosion rod or impressed current anode or are made of copper. The required safety equipment is specified in DIN 1988. Thermostatic and mono lever mixer taps can be installed at the draw-off points.
