Electric Boiler
The most cost-efficient heating device for single-dwelling units, multi-dwelling units and bungalows. As a standalone heat and hot water system it works best with photovoltaics. It perfectly complements other devices, e.g. solid fuel boiler, heat pump or fireplace and effectively supports other heating devices in emergency or fuel shortage situations.

Features

CONVENIENCE

Boiler control using a colour touch panel with temperature sensor installed in the room (standard) and various functions e.g. ‘heat now’. A schedule lets users benefit from the economy night energy tariffs.

 

EASY INSTALLATION AND SAFETY

No need for a boiler room or fuel storage room - ELE boiler can be cheaply, easily and safely installed in any location in the house due to its silent operation and no flue gas emission. The device does not require gas and chimney connection and does not have to meet the strict ventilation requirements - all you need is an electrical energy supply.

 

ULTRA-SILENT

The device is very quiet thanks to silent semiconductor relays used to activate individual heating modules.

 

SOFT START

Gradual increase in power without excessive load to the power supply system.

PHOTOVOLTAIC COMPATIBLE

PHOTOVOLTAIC COMPATIBLE

Surplus energy from your photovoltaic system can be used to heat your home. An average photovoltaic system in a single-dwelling unit provides approx. 10 kWp corresponding to approx. 10,000 kWh a year on average. Average energy demand for lighting, household devices and home entertainment devices is approx. 3,000 kWh a year. The remaining energy from the sun can be used to heat spaces and water using KOSTRZEWA ELE electric boiler. Using renewable energy sources in residential applications can help us transition from fossil fuels and resolve the climate crisis.
