Water heater insulation is important because it improves energy efficiency. Insulation reduces heat loss, meaning that the water remains hot longer. As a result, the water heater doesn’t need to run extra cycles, lowering energy bills. Even still, many homeowners fail to insulate their heaters.
Here’s what to know about this important topic to make informed decisions for more sustainable homes.
NEED FOR INSULATION
Today, most water heaters come with pre-installed insulation.
However, getting an insulation kit makes sense if the insulation is poorly done. The same applies to older water heaters and those with no insulation. Bring in a professional to assess the situation and avert possible safety issues. An expert can provide qualified advice on whether to add insulation or not.
BENEFITS OF INSULATION
Energy efficiency is the main benefit here. The insulation serves as a barrier to keep heat from escaping the tank. This reduces energy consumption.
Water heater insulation is especially handy over the winter since the low temperatures make it harder for water to remain hot.
Apart from retaining heat, insulation protects the water tank from dirt and dust.
INSTANCES WHEN INSULATION IS NECESSARY
As a water heater ages, its efficiency plummets, and it needs to work harder to heat the water to the required temperatures. Proper insulation allows the tank to keep the water hot for longer, extending the heater’s lifespan before replacing it.
The tank’s R-value is the other thing that determines whether to insulate a water heater. It measures the insulation’s thermal resistance. A higher R-value means greater insulating power. When the value is below 24, consider adding some insulation to make the tank more efficient.
WATER HEATER INSULATION TYPES
There are a few types of water heater insulation available. While some may be installed as a DIY project, others require a professional’s assistance.
- Water heater blankets are affordable and effective insulation in different materials, including wool, foam rubber, and fiberglass. It creates an air pocket around the tank, reducing heat transfer between it and its surroundings. Usually, blankets will come in various sizes that can fit over a specific tank based on its volume. Most blankets have adjustable straps that make installation straightforward.
- Spray foam insulation involves applying insulating foam around the tank. Applying the foam takes little time but needs professional assistance to avoid making a mess or damaging the components.
- Reflective insulation redirects heat back to the water heater’s interior. This reduces energy loss, and as a result, the water remains hot for a longer time. Reflective insulation usually comes in rolls that can be cut and strapped around the tank.
WORK WITH EXPERTS
Whether a system needs extra insulation or it is safe to add one requires expert assistance. Contact a water heater professional for further assistance and guidance.
