How Our heating battery Works
Our sand battery works in a configuration made of 4 parts:
1. The air heater device
(batsand component)
During summer time resistive heaters get air to 500C degrees. The air is then blown in a closed loop (inlet/outlet) through insulated stainless steel pipes to the sand vessel.
3. Air/water energy transfer
(batsand component)
When winter demands, the air is recirculated by the air/water heat exchanger, warming water until 70-80C (according to the needs), the hot water is then utilized in the central heating of the house.
2. Sand vessel
(DIY by Batsand Blueprints)
Air at 500C degrees arrives at the bottom of the vessel, circulates, and heats the sand tank. After losing its energy to the sand, the air is then extracted and heated again until the tank is at stable 500C degrees.
4. Electronics
(batsand component)
The brain. It detects when PV systems are sending the surplus electricity to the grid and activates the Air heater to consume it. If no PV systems, the API will check the local grid for pricing of Kwh and turn on when the price is low or minus.

25Kw System
For medium and large houses
The system is designed to supply heating for residential buildings from 400 to 1200m2 depending on the heating efficiency of the building envelope.
This system needs a sand vessel of 70m3 to 120m3 (depending on building size). Constructed according to Batsand blueprints designed purposely for this system. And it should be at a maximum distance of 8 meters from the heating equipment.

Heating battery Power and Prices
The table below shows the average prices in Europe for the cost of a full system per household.
Please be aware that if your country doesnt have dynamic electricity pricing with very low rates in summer time, we recommend you to assembly the system to solar panels with the recommended power (kW) in the table.
​
The estimation of the price for the solar panels varies according to the country. But as best practice, we recommend checking price for panels and inverter online to understand if prices from solar companies is up to the market price for the equipment.
