| Cost to install | A fraction of the cost or hydronic/tubing systems. Sometimes up to 70% depending on location. | Boilers, pumps, manifolds, expansion tanks, zone valves, insulation and tubing |
| Cost to operate | Depending on power source, typically 30%-60% less cost to operate | Insulation limits the thermal mass and creates higher operating costs. Constantly reheating water/glycol to maintain temperatures |
| Foam under the slab | Not required for thermal mass earth storage systems | Typically required and adds material cost and labor to install |
| Off-peak electric rates | Qualifies for off-peak or other control programs offered by many power companies, sometimes rebates as well. | Restricted mass hydronic/tubing systems don't qualify for Off-Peak programs |
| Mechanical room | Takes up very little space on a wall. | Many tubing systems require a separate room or considerable room in the mechanical room. |
| Maintenance | No Maintenance, replacement or repairs. Silent and invisible. | Yearly maintenance and eventual repairs and replacements of many components, including the boiler. |
