Tank vs. Tankless Water Heaters: How Do You Choose?
It appears my 30 year old electric water heater is coming to the end of its useful life. We now wait for up to two minutes for hot water in the kitchen and upstairs shower. I’m considering replacing it with a new model. I know Solar water heater is the future, but we plan on living there for 15+ years. Basically I’m looking for a tank or tankless water heater that can support 3 or 4 hours of nearly back to back showers.
The biggest problems that you will find the hot water is not having enough, especially for a big family. Traditional water heaters can run out of hot water and then need some time to reheat water. Typically, traditional water heater that stores 40 to 60 gallons of hot water at a time in a tank. Tankless water heater heat water when it’s needed. They can bring hot water with soothing temperatures in a second.
The cost depends on whether you want save money with a long-term investment or just want a quick fix on your house hot water system. Well right off the bat, the cost of a tankless is higher than a tank water heater. From the report, the cost of tank water heater installation is cheaper than a tankless water heater. Gas tankless water heaters often need larger diameter gas pipe, which increase your budget.
As compared with tank water heaters that are supposed to last 10-13 years, a good tankless water heater comes with a longer lifespan, some models can last up to 25 years. If you are not going to move your home for that long, then it’s nice to choose a tankless water heater. You’d soon see that savings would probably exceed your lifespan.
If the money and lifespan are not problems, then space is another important thing you need to consider. Traditional water heaters are generally around 50’’ tall and 24 ‘’ wide, while tankless water heaters have a tiny footprint compared to a storage tank water heater. If your space is limited, having a tankless water heater on the wall is a good option to free up space.
With a tank water heater, you can several tasks at the same time, there is no need to worry about the flow rate. While tankless water heaters are difficult to meet your needs as its limited flow rate. More tasks means bigger tankless devices. So if you have a large family and everyone’s taking a shower, tankless water heaters are not the best one.
Tankless water heaters also typically have a longer warranty because keep it works very well is an challenge. Calcium buildup can decrease efficiency, some even damage tankless models. There is a lot of things you have to do regularly. Of course, the maintenance mostly depends on the location. When it comes to keeping your tankless water heater efficient, remove the mineral deposits at least once per year.
