Electric Boiler
Thermal Storage Solutions
With 100–5000 liter storage and 2–120 kW heater options, it scales from residential to heavy industrial facilities.
About the Electric Boiler
With 100–5000 liter storage and 2–120 kW heater options, it scales from residential to heavy industrial facilities.
It requires no external boiler, flue, or gas line; immersion heaters convert electrical energy into heat and keep the water ready at the set temperature.
What Is an Electric Boiler?
Immersion heaters bring the water to the set temperature; strong insulation keeps heat in the tank for a long time so the unit does not run continuously unnecessarily.
Operating Principle
A Legionella protection program periodically raises the water to a high temperature to support hygiene; residual-current and over-temperature protection ensure safe operation.
Independent Operation and Flexible Installation
It eliminates the need for a central heating system or flue connection.
Safe and Clean Energy
Because it does not use natural gas, LPG, or fuel oil, there is no gas-leak or carbon-monoxide risk; it produces no flue gas or combustion emissions. It provides emission-free, quiet, and clean hot water in enclosed spaces and is preferred in green-building and environmentally conscious projects.

Frequently Asked Questions
It is a storage hot-water heater that operates on electricity only. Immersion heaters heat the water; a thermostat or ProWatt panel maintains the target temperature. No external boiler or flue is required; it is offered in the 100–5000 L and 2–120 kW ranges.
It is used in homes without gas infrastructure, commercial spaces such as gyms / restaurants / salons, factories and communal shower facilities, hospital and food-process water, green-building projects, and hotel/hospital backup hot-water needs.
Storage and kW are calculated from number of people/showers, target temperature, mains inlet temperature, and usable tank ratio. In the brochure example, PROWATT 1000/10 – 3x15 is selected for a 30-person shower scenario. Tanpera engineering sizes each project specifically.
Maximum operating pressure is 10 bar; maximum operating temperature is 95 °C. The typical set range is 30–85 °C. Units are tested at 1.3× design pressure before delivery.
It offers IP 54 protection, TR/EN LCD menu, real-time programming, temperature/voltage/fault readout, residual-current plus high-low voltage and high-current protection, a Legionella program, and operating/fault signaling to building automation.
100–1000 L: 50 mm, 42 kg/m³ rigid polyurethane + Termowen cladding. 1500–5000 L: 80 mm, 18 kg/m³ open-cell soft polyurethane + vinyl jacket. This construction reduces standby losses.
Annual authorized service maintenance, magnesium anode inspection/replacement, and scale management are recommended. The anode is a consumable. Domestic water must comply with regulations; excessive hardness shortens heater life. A TS EN 1487 safety valve is mandatory at installation; the tank must not be heated when empty.
Yes. In addition to electricity-only operation, efficient hybrid operation with other energy sources is possible by adding a water coil or plate heat exchanger. Non-standard accessory and insulation options are available on request.
