Newton Energy Solutions says its new thermal storage system is ideal for homes equipped with solar panels and heat pumps or gas boilers. The battery has an energy storage capacity of 20 kWh to 29 kWh.
Dutch heating specialist Newton Energy Solutions has introduced a new thermal energy storage system for residential applications.
“NEStore is an optimal solution for homes or buildings with photovoltaic systems and can be combined with heat pumps and gas boilers,” a spokesperson told pv magazine .
The system features patented 3cm thick vacuum insulation and a design that reduces the number of thermal bridges.
“This combination ensures that the system minimizes downtime losses to 1% per day,” the spokesperson said. “Good insulation against water temperature, without causing energy losses due to high temperatures.”
The system is available in two versions, with water volumes of 214 liters and 320 liters and energy storage capacities of 20 kWh and 29 kWh.
The smallest product measures 1,650 mm x 590 mm and weighs 154 kg. The largest version measures 2,050 mm x 590 mm and weighs 190 kg.
For both systems, the voltage is 230 V and the set temperature ranges between 55 ºC and 110 ºC. The heat loss for the first system is estimated at 1.44% per day, while for the second it is 1.35% per day.
According to the manufacturer, the 20 kWh product can heat 600 liters of tap water to 40ºC, which, in its opinion, is enough for a shower of approximately an hour and a half or to provide up to four days of hot water for a family. of four people.
“The NEStore is charged when there is surplus energy from the solar panels, or based on the most favorable dynamic energy rates,” the spokesperson added, noting that the system can be installed in new or existing buildings.
The thermal battery costs between 200 euros ($218.80)/kWh and 250 euros/kWh.
“That is well below the costs of domestic electric batteries that sell between 750 euros/kWh and 1,000 euros/kWh, and above the costs of a standard electric hot water boiler, of about 140 euros/kWh” said the spokesperson.
Newton Energy Solutions began selling the thermal batteries in July and plans to increase its production capacity in 2024. |
