Energy Saving at Home

Water Heating

Big energy saving at home steps can be achieved in domestic hot water heating. Replacing your older water heater with a newer more efficient model will yield major energy saving at home results. It will save you money and save our planet's valuable resources. Here are quite a few additional tips to help you extend your energy savings at home.

Energy Saving Tip # 92

When purchasing a new water heater, check with your local power utility and tax authority.  There may be rebates and tax credits for adding solar heat to your domestic hot water system.  Search for various databases of state, county, municipal, and power utility incentives – you may save a lot more money in addition to the energy you save.

Energy Saving Tip # 93

Only wash full loads in the dishwasher or clothes washer.

Energy Saving Tip # 94

Shorter showers save hot water and money.

Energy Saving Tip # 95

In many areas, geothermal heat pumps may be a very economical way to heat your domestic hot water.

Energy Saving Tip # 96

On-demand/tankless and indirect water heaters have become a very energy efficient alternative to traditional tank type hot water heaters. You may save as much as one third compared to the older designs.

Energy Saving Tip # 97

Your shower sends warm water down the drain – sometimes more than 80% wasted heat that costs you a lot of money.  Drain waste water heat recovery systems may use as much as one third less energy for water heating compared to older systems.

Energy Saving Tip # 98

New energy-efficient water heating systems may cost more to buy and install, but the energy savings go on as long as you own your home.

Energy Saving Tip # 99

Did you know that most regular tank type water heaters will last for 10-15 years?  But the best plan is to start looking for a new water heater, preferably one that will use less energy than the one you are now using, when your existing unit is seven or eight years old. If you have your research done before the unit fails, you will be able to replace your water heater BEFORE it fails and leaves you with no hot water.  Having to replace it as an emergency action leaves you no time to make decisions that will save you a lot of money.

Energy Saving Tip # 100

A good practice every 3 months or so is, using the drain valve at the bottom of your hot water heater, drain half gallon of water or so.  This will clean out any sediment that accumulates which slows transfer of heat from the heat source, and lowers the efficiency of your heater. The instructions that came with your unit will give you the best procedure for doing this.

Energy Saving Tip # 101

Heat traps installed on the inlet and outlet water pipes right at the water heater help to prevent heat loss. Many newer models may have these energy savers built in.

Energy Saving Tip # 101

Of course, when you are looking to buy a new clothes washer or dishwasher, make sure you get a water saving and efficient ENERGY STAR® model which will save you energy and money.

Energy Saving Tip # 103

Insulate all of your domestic hot pipes, and the five to ten feet of cold water inlet pipe closest to the water heater.  This may raise the temperature of the water at your faucets by several degrees so your water heater doesn’t have to work so hard.  This will save you money.

Energy Saving Tip # 104

If you have hot water heat, make sure all the hot water pipes are insulated.  This can save you a lot of money.

Energy Saving Tip # 105

Make sure that your domestic hot water storage tank is well insulated.  The better the insulation, the less the heater will run to make up for temperature loss through the tank walls.  This will save you money.  Make sure you don’t block any thermostats, the burner area, any drains, or any air vents. The manufacturer’s instructions will give you guidance for the areas that should and should not be covered.  If there is any doubt, be sure to ask a professional.

Energy Saving Tip # 106

Showers use less water than baths, so by all means, that is the best choice.  This will save you not only money, but time.

Energy Saving Tip # 107

Many water heaters are delivered with the temperature set considerably higher than needed.  Setting the thermostat to a lower temperature, around 120°F, will give you plenty of hot water, and could save more than 3% on your water heating costs over the years.

Energy Saving Tip # 108

Leaking faucets waste a lot of water, especially hot water.  Fix them as quickly as possible to save your money.

Energy Saving Tip # 109

A great way to save both hot and cold water and lower your water and energy bills is by installing aerating, low-flow faucets and showerheads.

Energy Saving Tip # 110

Shopping for a new shower head?  Find one with a flow rate rated at less than 2.5 gpm (gallons per minute). Many older shower heads had flow rates in excess of 5 gpm, so replacing them can potentially save you quite a bit of money.

Energy Saving Tip # 111

Do you have a heater for your swimming pool?  A great addition to your heater is a solar pool cover.  This absorbs the sun’s heat to warm the water, and drastically reduces evaporation which significantly cools the water.  It’s a double win!
