The ideal solution for a gas boiler
I use the EcoFlow DELTA 3 Plus to power the gas boiler, and I can say it's top-notch for its money.

For a price of about €954 — it's absolutely worth the purchase. If you need longer runtime, go for a model with a larger capacity, but technologically, it's one of the best and most modern options today.
Here's what stood out to me:

UPS Functionality: Switching time is less than 10 ms — the boiler doesn't even "notice" the power outage and operates stably.

Autonomy: My boiler runs for more than 12 hours — a big buffer even during prolonged outages.

Quietness: Unlike previous EcoFlow models, which were noisy due to fans, the DELTA 3 Plus operates virtually silently even under load and during charging.

Reliability: LiFePO4 battery with a huge cycle life and over 20 levels of protection.

Comfort: Fast connection through the app, convenient management, and automatic charging.

Intelligent Management: A very cool notification system in the ecosystem. If correctly configured, it alerts you about future outages, allowing you to charge the station in advance. Also, in UPS mode, it optimizes charging itself, so you're always ready for a blackout.
So far, everything is working wonderfully and properly because I am using it correctly.
