The answer to 'water heater high energy bills' is that there are several common causes, including a malfunctioning thermostat, sediment buildup, and poor insulation. Symptoms may include inconsistent water temperatures, longer heating times, and unexpectedly high energy bills. Solutions can range from simple DIY fixes to more complex repairs that require a professional HVAC technician.
For example, a faulty thermostat can cause the water heater to work overtime, leading to higher energy usage. Sediment buildup can also reduce efficiency and lead to higher bills. Inadequate insulation around the tank or pipes can allow heat to escape, forcing the water heater to work harder to maintain the desired temperature.
