How to Improve the Energy-Efficiency of Your Hot Water Heaters

Water heaters generally have a lifespan of 8-10 years if they are used carefully and maintained well. This means if you find that your water heater consumes excessive amounts of energy once you have installed it, you can’t just replace it for a newer and more energy-efficient model. However, there are quite a few things you can do to improve the energy-efficiency of your hot water systems. Regardless of whether you have an electric, gas or solar water heater, here are some tips that will help

  • Install a water heater jacket– Even when the system isn’t in use, it still has a certain amount of hot water in its tank and this heat can be lost through the tank walls if its insulation isn’t up to the mark; this is called standby loss. Simply encase the water heater in a good quality water heater jacket to reduce its standby loss by at least 25%- 50%. If you have a newer model of water heater, this isn’t something you need to be concerned about as they have a sufficient amount of insulation already.
  • Insulate your water pipes– When you insulate the water pipes, it raises the hot water temperature at the faucet or showerhead considerably. You should insulate only the first 15-20 feet of pipes leading out of your hot water system.

Improve water efficiency

Insulating the pipes and the actual heater helps reduce energy costs drastically, and helps you save water too. Properly insulated pipes help maintain the water temperature; and so when you take a bath you don’t need to keep the water running till it’s warm enough for a comfortable shower.

Maintain your water heater with regularity

Even when you buy a very high quality hot water system, get it installed from experts and follow the tips mentioned above, your heater will function well only if it is maintained with regularity. Hire the services of a good licensed plumber in Sydney to come and inspect the system and service it every 6 months.

If they notice any potential problems, they will fix them without delay and will also ensure that the insulation is up to the mark. This will keep the system functioning well for a number of years. Regular maintenance will also ensure the long-term, energy efficiency of the system and save you a significant amount of money over the lifespan of the system.
