Neothermal ETS Whole Home Supplemental Heating and Hot Water
Add electric thermal storage without the expense of replacing your heating system
How It Works
Neothermal ETS (electric thermal storage) stores heat in the same way as a reusable hand-warmer. What’s neat about using salt is that it remains a liquid as it cools, keeping the chemical energy stored without any heat loss. When more heat is needed, Neothermal ETS will crystallize the salt mixture, changing it from a liquid to a solid, releasing the stored chemical energy.

Overnight on weekdays, the salt and water mixture inside the device is slowly heated to 100˚C using a built-in electric heating element, transforming the salt mixture from a solid to a liquid; taking up to 8 hours for a complete charge.
During weekdays, Neothermal ETS responds to your thermostat, drawing stored heat from the cells and gently heating the room via your central heating system (forced air or hot water radiators) or wall-mounted fans (room ETS only).
On weekends, Neothermal ETS will function as a regular electric supplemental heating system.
Flexible – works with any furnace or boiler and hot water system (optional), even when replaced or upgraded.
Supplemental – integrates easily into your furnace or boiler’s return duct/tubing and your hot water system’s cold water supply line.
Hot water – save year-round by adding hot water heating to Neothermal ETS.
No panel upgrade – designed to avoid an expensive electrical panel upgrade for most homes.
Ease-of-use – shares a thermostat with your main heating system; you set the temperature and the thermostat and ETS do the rest, giving you optimal savings and comfort.
Smart home control – uses smart home controllers to manage TOD rate schedule and system charging; also uses OpenADR protocols to manage real-time demand response (DR) where utility programs allow.
Long-term Storage – holds nearly 50% of the stored heat for up to a year. This capability allows you to carry over unused energy to a following day. This technology also has the potential to heat your home for 1-2 days during a power outage by using a back-up battery to run the device (this feature is under development).
Safety – operates at much lower temperatures (≤ 100˚C) than conventional brick ETS, which can heat up to more than 600˚C.
Efficiency – designed for 90% efficiency no matter the weather.
Long-lasting – built to last over 20 y.
When fully heated, Neothermal ETS is designed to provide 12-16 hours of heating.
A typical Neothermal ETS system of 4 modules is designed for homes of up to 1,500 square feet (≤ 140 m2) and can be expanded by up to 4 additional modules for homes of up to 3,000 square feet (≤ 280 m2).
A typical Neothermal ETS system stores 32 kWh of energy using 4 modules, equivalent to 70 car batteries. Up to 4 additional modules can be added for larger homes.
A typical Neothermal ETS system with 4 modules consumes 5.1 kW when charging or running as an electric heating system on weekends/holidays; it consumes 150 W to power its pumps when releasing stored heat. A system equipped with 5-8 modules would consume between 6.4 kW to 10.2 kW when charging or on weekends and 190 W to 300 W when releasing stored heat.
A certified electrician or HVAC contractor can deliver and install your Neothermal ETS for you and recommend the number of modules for your home and budget.
