The DBE OPTIMA electric boiler is an advanced heating device that ensures maintenance-free and safe operation The design of the boiler allows it to operate without emitting exhaust gases, which makes it one of the safest devices dedicated to central heating and hot water systems.
It does not emit any pollutants or gases dangerous to the environment. The installation of the device itself is relatively simple and does not require large financial outlays. The boiler can function as the main heat source, especially in houses with good thermal insulation and underfloor heating operating at a low temperature. It may become the best option to choose.
It can also function as a supporting heat source for a solid-fuel boiler, a condensing boiler, a fireplace or even a heat pump in more difficult winter conditions. The boiler efficiency of 99.6% allows you to quickly obtain the desired temperature in the room. Electric boilers from Defro are an ideal solution for cooperation with a PV installation. Thanks to the solutions used in them, you can increase the level of auto consumption in a controlled way, which allows you to significantly shorten the payback time of the investment in a photovoltaic installation. With full control over the boiler thanks to a mobile application that allows you to control the boiler functions at any time from your smartphone.
