An electric thermal storage heater is an innovative heating system that stores heat when electricity demand is low and releases it gradually throughout the day. This principle, known as thermal energy storage, offers an economical, eco-friendly, and durable solution for your home.

In this article, you’ll learn how an electric thermal storage heater works and why it’s an excellent choice for both your comfort… and your wallet!

How Central Heating with a Thermal Storage System Works

An electric thermal storage heater draws in outdoor air and directs it toward electric heating elements located inside the unit. These elements heat a core of ceramic bricks, known as a thermal mass, which stores the generated heat for later use. When the room temperature drops, the built-in fan activates to release the stored heat and distribute it evenly through the home’s existing ductwork.

This type of heating system is often used in combination with a central heat pump to maintain a consistent indoor temperature and maximize efficiency.

Smart Energy Management

During peak demand periods — typically from 6 a.m. to 9 a.m. and 4 p.m. to 8 p.m. — when the electricity grid is under greater strain, the thermal storage unit automatically reduces its power consumption.

It stores heat during off-peak hours and releases it later, without any action required on your part.
This smart energy management lightens the load on the electrical grid and helps you save money while maintaining a steady, comfortable warmth throughout your home.

It’s this intelligent energy control that truly sets thermal storage heaters apart from traditional electric systems.

Electric Heating and Dynamic Pricing: A Winning Combination

An electric thermal storage heater is the perfect companion for Hydro-Québec’s Flex D dynamic rate program. This rate rewards homeowners who shift their energy consumption to off-peak hours — and that’s exactly what a Steffes Serenity system is designed to do.

By charging mainly when electricity is less expensive and reducing power use during high-demand periods, your system helps you lower your winter heating costs without compromising comfort.

Authorized Steffes Installer on the North Shore

To qualify for Hydro-Québec’s financial assistance, the installation must be carried out by an authorized Steffes contractor, such as Les Entreprises MPH. Specializing in heating, air conditioning, and ventilation, our certified technicians handle every step: from selecting the right model to installation, maintenance, and repair. You’ll benefit from a professional, detail-oriented service — with no subcontracting — delivered by experienced HVAC experts.
