For homes without gas or oil heating, electric storage heaters have long been an alternative. Traditional models, however, are wasteful and provide inconsistent heat. Modern high heat retention storage heaters store cheap off‑peak electricity and release warmth gradually throughout the day, making them far more efficient.
The Consumer Rights guide on ECO4 heating measures explains that storage heaters are designed to take advantage of time‑of‑use tariffs like Economy 7. They charge overnight when electricity is cheaper, storing heat in ceramic bricks and releasing it slowly. Components include:
Because heat is stored inside the unit, high‑retention heaters can provide warmth throughout the day without continuously drawing power. They are ideal for homes without central heating or for residents looking to reduce peak energy consumption.
Modern storage heaters are typically installed in one to two days and have an expected lifespan of 15–20 years. Upgrading to high‑retention units can improve comfort and reduce your electricity bills if you’re on a time‑of‑use tariff.
High heat retention storage heaters are one of the approved measures under ECO4. If you have an EPC rating of D or lower, you may qualify for support. Some households not on benefits may also be eligible through the GBIS scheme. Use our eligibility checker to find out more.
