Keep Your Energy Costs Down With The Right Water Heater Blanket


It is important to note from the onset that not all water heaters require blankets. This is because most modern water heaters are well insulated. It is also worth mentioning that there are manufacturers who are quite categorical that you shouldn’t use a blanket on that particular heater. However, whether to use or not to use a blanket is a personal one. There are several tests one can perform to confirm whether one should use a blanket or not. A simple test does involve placing your hand on the side of the water heater and feeling how warm or cold the tank is. If you feel any warmth then it means that some heat is escaping and the water heater could use a blanket to keep the heat inside the tank. It is also important to keep in mind that most heaters are designed to keep the water heated up to 140 degrees and so some heat is bound to escape to the outer atmosphere which is usually much colder. By insulating a water heater and plumbing pipes, you are bound to increase the overall efficiency of the unit and reduce any instances of heat loss.



The use of water heater blankets does stand out as one of the most common, affordable and effective ways of reducing instances of stand by heat loss and also increase the temperature of the hot water by a few degrees. When buying a blanket, there are several factors one has to take into consideration certain factors.

It is highly recommended that you get precut insulation kits since they have everything you need. The important thing you need to consider is the capacity of the heater tank. This is important because the kits come in standard sizes which are measured against the capacity of the unit in question. Some of the most common sizes include the 30, 40, 50, 65, 70 and 80 gallon tanks.

It is important to also take into consideration the R value. The most common rating is the R-11 rating which is deemed by many as the most effective. Once you have chosen the most appropriate blanket, it is important to ensure that it is fitted properly. When you are cutting the blanket, make sure that you don’t insulate the bottom or top portions; this is especially so if it is a gas heater as these may catch fire from the heat that’s generated by the flue gases. You should also ensure that the pilot light and flue draft. Because electric heaters don’t have an exhaust, it is highly recommended that you cover the top. When wrapping the heater, make sure you don’t block any vents or connections such as access panel. Drain valve and TPR valve. You can achieve this by cutting out a section of the wrap with a few inches of clearance around these elements.

When wrapping the blanket around the tank, make sure you don’t overlap the edges. To achieve this, make sure you cut the insulation several inches larger than the top; you should then fold the edges down and then tape it to the side of the tank in question. Once this has been achieved, you should tie or tape the blanket snugly and ensure you don’t squeeze more than twenty percent of its original thickness.

Once it has been installed, you should make sure that the blanket is not bunched, gaping or torn as this may significantly reduce its overall effectiveness. Here are some of the popular water heater blankets in the market. They include but are not limited to the following:
