Boiler tune ups: Save up to $750
add
Get up to $750 for tuning up hot water or steam boilers every two years and keep your boiler systems running at peak energy and economic efficiency, while extending the life and safety of your equipment. The cost of your boiler tune-up may actually pay for itself with the combination of energy savings and qualified rebates.
Potential Boiler Tune Up Savings* Example:
Boiler tune up cost $1,000 (estimate)
Rebate -$750 (75% of cost)
2-year savings* -$250 (75% of cost)
Your Net Cost $0 (free tune up)
* Based on average boiler tune up savings model for 800,000 Btu/hr, 70% efficient boiler. Actual energy saving results may vary.
| Service | Requirement | Rebate |
|---|---|---|
| Gas-fired boiler tune-up | Flue-gas tap (copy) or results | 50% of installed cost up to $500 per boiler |
| Gas-fired boiler tune-up (non-profit) | Flue-gas tap (copy) or results | 75% of installed cost up to $750 per boiler |

Spire custom business rebates
Custom rebates
add
Custom rebates are available to Spire commercial and industrial customers for the installation of any natural gas related energy efficiency improvement that does not qualify for a standard rebate. All custom rebate projects must receive a rebate commitment from the program prior to the starting the project. Custom projects are analyzed and pre-approved using program benefit/cost criteria determined by incremental energy-savings, project cost and payback. Projects must achieve a minimum two year payback to receive a rebate. Rebate amounts are individually determined by project and are calculated as the lesser of:
- A buy-down to a two year payback
- $6.63 per MCF saved during the first year
The following are examples of how each of these criteria could determine the custom rebate:
Custom rebate with lower energy savings
| Incremental project cost | $130,000 |
| MCF savings | 3,400 |
| Customer annual bill savings | $22,400 |
| Payback | 5.8 |
| Rebate at two year payback | $85,200 |
| Rebate at $6.63 per MCF | $22,542 |
Spire rebate | $22,542 |
Custom rebate with higher energy savings
| Incremental project cost | $55,000 |
| MCF savings | 3,800 |
| Customer annual bill savings | $22,400 |
| Payback | 2.46 |
| Rebate at 2 year payback | $10,200 |
