If you live in areas where winter can be bitingly cold, it is important that you have ready-to-use hot water 24/7. A typical residential water tank can hold up to 60 gallons of hot water every day but when the tank does not have enough insulation, the heat from the tank could easily dissipate. That is why it is important that when you’re doing house insulation, you must not forget to check the temperature of your water tank too. If it feels too warm when you touch it, then that signifies that you need to work on improving your tank’s ability to store hot water.
Why do you need insulation around water heaters
Fuel is consumed when water is heated. If there is enough insulation, hot water remains hot even if the tank is no longer using fuel to make it hot. If left on its original casing, your water tank losses around 25%-45% heat. But with enough padding, you can save about 4-9% in water heating costs.
Insulating Water Heaters
Water heater insulation can be achieved in various ways. The easiest and fasted fix will be to wrap the tank with a fiberglass blanket. There are kits readily available that contain the fiberglass blanket, heavy plastic sheet and a heat-resistant tape to keep the blanket in place. There are also kits that include materials for insulating the water pipes.
But if you don’t have the time to perform the above-mentioned insulation process yourself, you can also pay for foam insulation. Foam or cellulose insulation is recommended for intricate piping systems because it easily fits through any space.
No matter which material you choose, there are a few things that you should remember about insulation around water heaters.
- If you will use pre cut blankets, make sure that you measure your pipes and water tank first. Also, clean the area to make sure that the tapes will really stick to all the elements of your water heating system.
- Go for pipe and water tank blankets and jackets with an R-value of 8.
- Don’t forget to add a bottom board under the tank if you want to save more heating energy.
- Make sure that insulate the pipe nearest your water tank. This is because the greatest heat loss is said to take place in the pipe closest to your tank. By making sure that that part is well-insulated, you are saving more energy than you would if you wrap everything up aside from that one pipe.
- Set the thermostat between 120 and 130 degrees. Anything lower will cool your water down and anything higher will overheat the wires.
You may do the water heater insulation process on your own only if you have an electric water heater tank because the plumbing is more direct and uncomplicated. However, if you own a gas water heater tank, it would be best to hire some professionals who have been trained for the job. This insulation is highly combustible and if you do the job wrong, injury and the heater getting messed up are possibilities.
