So here's the facts more or less:
Current standby system operates at $10 per day 60 days on average for cost of $600
1/4 HP 115v Brookwood would run same time period for $40
1/2 HP 230v Brookwood would run same time period for $68
The 1/2 HP unit would give me an extra margin of error in capability and still get me the lion's share of the cost savings, but the operating cost is about 70% higher. Then again $28 more cost is peanuts compared to the $500+ savings.
This is assuming the $10 per day estimate is correct.
