Iceverge Posted March 10, 2022 Posted March 10, 2022 Have you considered using your concrete slab as a Battery? If my calcs are correct, with no losses, an extra 1.5m3 of concrete holds 1kWh/degree. Adding 75mm of concrete to your slab of say 100m3 will add 5kWh of energy storage per degree of temp you raise it. If you raise the temp of the slab by 3 deg overnight its a 15kWh battery for an extra ~£700 in cost. Similarly an extra DHW tank at 300l can store 7kWh per 20 degrees. We use an immersion to store 14kWh overnight, again at a cost of about £700. The same ~ 30Kwh of Battery storage would cost over £10,000.
