Full Inverter Heat Pump GRAT 78000 BTU WiFi 25000 Gallon Heater

Description

Product Overview

The GRAT GTMF-B30Y full‑inverter heat pump is engineered with a high‑efficiency DC inverter compressor that intelligently modulates output to match ambient temperature and water flow. This technology reduces energy consumption while maintaining a steady temperature rise, delivering up to 78,000 BTU of heating power for pools up to 25,000 gallons. The robust stainless‑steel housing and corrosion‑resistant components ensure long‑term durability in harsh outdoor environments.

Designed for both above‑ground and in‑ground installations, the unit operates on 220‑240V and weighs 265 pounds, with compact dimensions of 48.5 x 39 x 23 inches for easy placement near your pool equipment area. The integrated defrost cycle protects the compressor during cold snaps, while the low‑noise operation—rated at just 41 dB—keeps the poolside atmosphere peaceful.

Connectivity is a core feature: the built‑in Wi‑Fi module pairs with the dedicated mobile app, allowing you to set precise temperature targets, create daily schedules, and monitor real‑time performance from any smartphone or tablet. The app also provides alerts for maintenance, filter status, and energy usage, giving you full control without leaving the comfort of your home.

Included in the package are high‑quality hoses, all necessary connection components, and a comprehensive user manual that guides you through a straightforward installation process. The system is backed by a three‑year warranty and 24/7 technical support, ensuring confidence and peace of mind for years to come.

Usage

Whether you own a residential backyard oasis or manage a small commercial pool, the GRAT heat pump adapts to a wide range of climates. In temperate regions, it efficiently raises water temperature from cool spring mornings to a comfortable 82°F, extending your swim season by several months. In colder areas, the defrost function prevents ice buildup, allowing the unit to operate reliably even when ambient temperatures dip below freezing.

Homeowners appreciate the ability to pre‑heat the pool before guests arrive, using the app to schedule a warm‑up period that aligns with party plans or evening swims. For fitness enthusiasts, the consistent temperature supports regular lap training without the discomfort of cold water, while families with children benefit from a safe, warm environment for play.

The heater’s quiet operation makes it ideal for residential neighborhoods, resorts, and wellness centers where noise restrictions are a concern. Its energy‑saving inverter technology translates into lower utility bills, making it a cost‑effective solution for year‑round pool enjoyment.

Installation requires a standard 220‑240V power source and a suitable water flow rate; the included hoses and connection hardware simplify the setup. Once installed, the system integrates seamlessly with existing pool filtration and circulation equipment, delivering uniform heat distribution throughout the water volume.
