Heating during blackouts: how to make your boiler room grid-independent

Ukrainian winters have shown: even the best boiler room is helpless without electricity. Circulation pumps, the control board, and the burner fan are all grid-powered. The good news is that making a boiler room energy-independent is entirely feasible. **Three levels of backup** 1. **UPS for the boiler and pumps.** A modern gas boiler together with a circulation pump consumes 80–150 W. A UPS with a battery can keep such a boiler room running for 8–15 hours. The cheapest and most common option. 2. **Energy-efficient pumps.** [APM/APE pumps](/catalog/nasosy) with electronic control consume 3–4 times less than older models. The lower the consumption, the longer the backup lasts. 3. **A generator** for extended outages — via an ATS (automatic transfer switch). **Hydraulics matter too** Correct piping reduces the pump power required, and therefore the load on the backup supply. A properly selected [Termojet pump group](/catalog/nasosni-hrupy) with a modern pump makes it possible to ride out a blackout even on a modest UPS. **Hybrid with a heat pump** Another path to gas independence is to add a [heat pump](https://tjheatpump.com.ua/). In a hybrid scheme the heat sources back each other up, and a buffer tank smooths the cycles. Keeping warm during outages is a whole-system question, not just a matter of the boiler.
