Frequently Asked Questions

• How do I choose the right output for a KARMA electric boiler? Just as with gas boilers, base your choice on the calculated heat loss of the heated building. With electric boilers it is also essential to check whether the capacity of your electrical connection to the house (flat) allows it - higher outputs (from roughly 12 kW upward) usually require a three-phase 400 V connection and a correspondingly sized main circuit breaker, which your inspection technician or the electricity distributor can confirm for you.
• Is an electric boiler worth it compared to a gas boiler or a solid-fuel boiler? An electric boiler has the lowest purchase price and the simplest installation (no flue is needed, since it burns nothing), but running costs for electricity are usually higher than for gas or wood/coal for the same amount of heat delivered. It is especially suitable where gas is not available, as a supplementary/backup source, or in a building with low consumption (well-insulated new builds, cottages, flats).
• How does an electric boiler regulate its output? Most models switch individual heating elements on/off in stages, while some more modern models also allow smoother power modulation - this affects the smoothness of heating and, to some extent, the lifespan of the switching components.
• Can I install this electric boiler myself? Connection to the electrical network, inspection, and commissioning must be carried out by a person with electrical qualifications in accordance with the applicable STN 33 2000 standard and related regulations - do-it-yourself installation is not permitted, either for warranty or safety reasons.
• Can this electric boiler also heat domestic hot water? With many models, yes, usually in combination with a separate hot water tank and a switching (3-way) valve that switches between the heating circuit and heating the tank - you can find the exact option and accessories needed for this specific model in the technical parameters above, or consult our customer service.
