BATTERY BACK-UP

[chromakey]

Good Day:

I live in Victoria, BC and I am more concerned with the outages during the "winter" months.

I would like to know how detrimental would it be if the water temp dropped below 60 Deg. F for 24 hours.

I was thinking of purchasing an inverter/charger system and two deep cycle batteries but the cost is about $700 and up.

Thanks,
Michael
