Breaking free from gas: the «boiler + heat pump + buffer» hybrid

Rising gas prices and the desire for energy independence are pushing Ukrainians toward heat pumps. But fully replacing a boiler with a heat pump means a large investment and the risk of falling short in peak cold spells. The smarter path is a hybrid system. **How it works** A [heat pump](https://tjheatpump.com.ua/) covers the base load for the majority of the season, when outdoor temperatures are between +10 and −5 °C — the range where it is most efficient. During severe frosts or peak demand hours, a gas or electric boiler kicks in. The controls automatically select the cheapest heat source. **The role of the buffer tank** The buffer accumulates heat, smooths out the heat pump's operating cycles, and prevents the sources from conflicting with each other. All consumer circuits connect to the buffer via a [distribution manifold](/catalog/rozpodilchi-kolektory) with [pump groups](/catalog/nasosni-hrupy). **Why this suits a gradual transition** You can start with a boiler and piping, then add the heat pump later — a hydraulic layout based on a Termojet [hydraulic separator](/catalog/hidravlichni-rozdilnyky) or buffer tank is already prepared for this. You reduce gas consumption as far as your budget allows, without a complete overhaul of the boiler room. **Keeping the heat exchanger clean** For long-term efficiency of the heat pump's heat exchanger, install a magnetic separator — it will keep the system performing at its best for years to come.
