At least a thermal load of ~50 tons is required for seasonal thermal storage to work efficiently; otherwise, storage volume will be too low resulting in higher loss factor for stored thermal energy. For residential applications (where the load is typically below ~50 tons), cluster of houses together can be provided with the ATES [ 9 ].
Phase change material based advance solar thermal energy storage systems for building heating and cooling applications: A prospective research

Solar Rooms
Most of the information in this chapter is applicable for relatively small solar rooms of 100 to 200 square feet. Unless your house is super insulated or in a mild climate, a solar room of this size will provide less than 25 percent of your heat. For big leaky houses, small solar rooms will provide as little as 5 or 10 percent of the heat.
Solar Thermal: Complete Guide to the Pros, Cons and Costs
Direct electricity: 2,184kWh per year x 28p (average) = £611.52. A saving of around £150 per year would give us a payback period of around 26 years on the capital cost of installing a solar thermal system, whilst a saving of circa £600 would give us a payback of just under 7 years.
