Energy Economics
The main difference is efficiency. A gas boiler delivers a maximum of 92–98% of the fuel's energy. An air-to-water heat pump has an average annual efficiency (SCOP) of around 3.5–4.5. This means that for every 1 kW of electricity consumed, you get up to 4.5 kW of heat.
Comparative Characteristics
Connection cost: Gas connection often requires complex projects and permits. Installing a heat pump only requires dedicated electrical capacity.
Safety: No open flame, no explosive fuel, no combustion products (carbon monoxide).
Autonomy and ecology: A heat pump can be powered by solar panels, making your home energy-independent.
2026 Verdict
At current Ukrainian energy prices, the payback period for a heat pump compared to a new gas connection is 4–6 years. In addition to heating, the pump provides summer cooling — an extra benefit at no extra cost. A gas boiler remains relevant only as a backup source in bivalent systems for very old buildings with poor insulation.
