Hot Water Heaters - Domestic hot water heaters make our lives much more comfortable than ever before. Hot water heaters give us hot water for washing our hands, showering, washing dishes and other uses that would otherwise be uncomfortable without a hot water heater. When considering hot water heaters beyond the cost of the water things to consider are the size of the hot water heater and the type of fuel it will use to heat the water. Efficiency plays a key role in the decision also and while the more efficient models are more costly to purchase paying the higher cost now will save a lot of money down the road in energy savings. Additionally, with all the tax incentives and utility incentives buying the more efficiency model may cost less than the less efficient water heaters. Before looking for a water heater it might be a good idea to check with your local utilities to find out what kind of incentives are available for buying higher efficient water heaters. After checking with the local utilities then you can go out looking for the best water heater to suit you and the purpose you need the water heater for. Tankless water heaters can also be a consideration although these should be sized by a professional so you don’t get too small of a tankless water heater (not enough hot water) or too large of a tankless water heater (inefficient).

Fan Maintenance Energy Savings - According to the Department of Energy fans consume nearly 80 billion kilowatts of energy per year. Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users. Assuming the design engineer selected the proper fan and proper installation in well designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)? To make a good evaluation you need to look at several different factors in fan operation.
- Fan Control
- Fan Performance
