A heat pump is an electrical consumer - and a large one at that
In sales materials, a heat pump is "cheap heating from the air". From the perspective of the electrical installation, it is a device that on a freezing day - together with auxiliary heaters - can draw from several to over a dozen kW. Added to this is the question of single- or three-phase power supply: most pumps of reasonable capacity run on three phases, and not every older house has them.
What we check in a pre-purchase audit
- connection and contract capacity - whether the house can "handle" the pump together with the induction hob, boiler and the rest; if not, what the capacity increase looks like and how long it will take;
- the distribution board - space for protections of the new circuit, condition of devices, surge protection (the pump inverter requires it);
- dedicated circuit - the pump cannot hang on a socket circuit; we calculate the cross-section and routing;
- the correct type of RCD - devices with an inverter require an RCD resistant to currents of a different nature than standard household appliances; a standard RCD may trip for no reason or - worse - fail to operate;
- earthing and equipotential bonding - the foundation of safety for every "electrical" boiler room.
The correct order of decisions
First the installation assessment, then the choice of device - not the other way around. A pump installer usually assumes that "power is there", and shortcomings come to light on the day of installation: lack of a third phase, a full distribution board, too weak connection. Then the cost rises at the worst possible moment. An electrical audit before signing the contract reverses this order: you know what the house is capable of, and you negotiate with the pump contractor with concrete facts in hand.
Subsidies - check at the source
The scale of change is real: for example, in Świdnica alone, by the end of 2025 r., 287 applications were submitted in the Czyste Powietrze programme (according to the state of the city report). However, the rules and intakes of subsidy programmes change too often to trust blogs - including ours. Always verify current conditions on the official websites of the programmes (Czyste Powietrze, Ciepłe Mieszkanie) or at the city hall. Status as of the date of publication: 12 July 2026 r. We are responsible for the part that does not change: the installation must be safe, measured and documented - also to meet the requirements of subsidy settlement.
Are you planning a pump, photovoltaics and an electric car? Calculate the capacity once, for everything combined - instead of three separate approaches. We do such an audit during a single visit: book a visit or use our expert consultation.
