The temperature in NY has reached well over 90 these past few days, and I don't have air conditioning. So even with no water heater, the temperature in the tank of my 2 young res is much higher than the optimum - it's at around 87 during the day. Is this harmful? Any suggestions for reducing it, other than geting air conditiong? I've been adding cold water from time to time, but this of course only helps temporarily.
I haven't even been using the heat lamp recently because it heats the water further. Advice would be appreciated.
