No, you just can't jump into a cold shower in winter, even if you actually have seen a good and sexy blockbuster flick on your
high-tech digital TV, you know. That's what water heaters are for: to heat up the water you're gonna use on your showers on any damn cold weather day. Water heaters are as essential as spicy food and a nice bottle of Scotch. Yet, you just can't conserve on your monthly energy bills if you plan on using your water heaters inefficiently. So, you should regularly turn down the thermostat levels of your water heaters to 120 degrees.
