Benefits Of Older Hot Water Heater Insulation

Here you will learn older hot water heater insulation benefits. Modern water heaters have a lot more control than older models. One feature in particular which has come a long way is how water heaters are insulated. Nowadays, insulation is built in which allows homeowners to save energy while preventing the ongoing maintenance of the tank insulation. Yet, older models, typically hot water heaters which are more than ten years old, do not have this feature. Therefore, it’s a smart idea to provide this insulation because you can easily and inexpensively increase energy efficiency this way.

Taking a bit of time to learn the heat loss protection of your older hot water heater has is a worthy pursuit and so is considering an upgrade to the unit if you find it is going to save you more money and energy in the long run. Water heaters which have insulation built in looks very similar to older models but they are usually a bit larger. The insulation is visible surrounding the tank which also has a shell that covers it.

You can determine whether you have a newer insulated hot water heater or an older unit best, by referring to the original documentation. If it is not easily available perhaps check for an online version. If this is not an option, look for an “R value” on the water heater labels. The symbol “R” stands for thermal resistance and indicates how well your older hot water heater resists heat loss.

You will notice the “R value” in the lower, single digits have very little if any insulation at all. Newer hot water heater models can have a value in the middle to the high twenties because they have a high-density urethane foam insulation. And there is no need to worry about thermal heat loss if you have an older water heater with a value in the upper end of the value scale.

Determine The “R Value” Of Your Older Hot Water Heater

If you don’t have an “R value” you should definitely consider upgrading your older hot water heater unit or at the very least invest in some insulating blankets. An insulation value in the teens can be a bit more complex because it may be that water heaters in this range were built without the expectation that they would need an insulation blanket, and if one were to be added that it may interfere with electrical components. In this case, it may be best to consult a professional plumber to learn whether it will be effective and safe to do.

An aftermarket insulation blanket would likely pay for itself within a year, or so. You can purchase one inexpensively at just about any home center or local hardware store for around twenty dollars. It’s easiest to install an insulating blanket on your older hot water heater with two people as a DIY project. You should initially note all of the electronic components, valves, and vents on the device because these should not be covered.

Wrap the older hot water heater around the tank and use a marker to carefully outline these components. Next, lay out the blanket flat on the floor and utilize a sharp utility knife in order to remove these areas. Then secure the blanket to the water heater with tape and you’re all set. This is a quick, easy, inexpensive method to increase the efficiency of your hot water heater. Yet, if you do have an older unit it may be time to consider an upgrade so you don’t have to be concerned about this issue at all.

Why Plumber.ca?

There are several plumbers out there. Many have experience. So why choose us over everyone else? Here are a few reasons:

check  No Hourly Charges – Many customers do not see the advantages of having a plumber who does not work by the hour. A plumber who works on a fixed price has no reason to stick around after the job is finished to ensure he gets paid more. Even if the job takes more time than required, you still pay the same amount.

check  Upfront, Exact Pricing – Every job we do has a set price shown in our price book. We go through with you exactly what the scope of the work will be to fix your problem and the costs involved. You know before we start what the final price will be -no surprises!

check  Rapid Response Times – Our highly efficient dispatch team will make sure our local plumbers are at your location as soon as possible. Under normal conditions, our technicians will arrive at your location within 48 hours. Service calls can take longer than expected and sometimes specialty parts need to be ordered, which may push the wait times longer than expected.

check  Priority Calls – Emergency calls are our highest priority. We know they can quickly become a serious situation. You can place a priority call to ensure you are the next customer to be serviced. The technician will be at your location within 24 hours. All priority calls require a credit card upon calling.

check  Local Plumbers – There is no sense in calling a plumbing service that is in another city. We have plumbers in all major city centers across the GTA that can respond to your emergency when you need it.

check  Fully Loaded Work Trucks – A fully inventoried truck is crucial so that your problem can not only be diagnosed quickly, but fixed quickly as well. Even if the job requires a specialty part, we can have it ordered within 24 hours.
