Features to Look for Before Buying Tankless Water Heater
Buying a tankless water heater can be an expensive endeavor, so you don’t want to end up with a poor-quality model that malfunctions too frequently. That’s why it’s important to consider several aspects and features before making your purchase. With that in mind, here are some crucial features that are worth your consideration.
· Initial Cost
Tankless water heaters tend to be pretty costly. Some are more expensive than others. Pricier tankless models usually come with added features and more advanced technology. However, it’s possible to get high-quality products without spending a fortune because there are plenty of affordable ones out there.
Despite the hefty price tag, these heaters will save you a lot of money in the long run as they are incredibly energy efficient.
· Fuel Type
Tankless heaters are fueled by gas or electricity. You have to make your choice between them. We aren’t going to indulge in an electric vs gas tankless water heater debate, but we’re going to clear things up.
Let’s start with electric tankless water heaters. They are smaller than natural gas tankless water heaters and easier to install as they don’t need any venting. You won’t have to do much maintenance either.
Additionally, they’re comparatively more energy efficient. However, they aren’t as powerful as gas-powered water heaters.
Gas tankless water heaters are incredibly powerful and offer a faster GPM flow rate. However, they come with an expensive price tag, require heavy spending on fuel costs for buying natural gas or propane, and installation is also more complicated.
Additionally, a gas water heater may require frequent maintenance as well.
A natural gas tankless water heater is meant for bigger houses that have a higher demand for hot water. It’s capable of offering faster performance and churn out tons of water without any issue. However, you would have to regularly purchase gas to keep a natural gas tankless water heater running.
If you’re looking for convenience, low-maintenance, and affordability, an electric tankless water heater will be a better choice than a natural gas tankless water heater. That’s only if you don’t need a heavy-duty device.
· Flow Rates
Hot water heaters come with flow ratings that tell how much water will flow out of your faucets at once. It’s an important thing to consider. Maximum flow rate is usually rated using gallons per minute or GPM. You have to choose the right flow rate for your house.
If you’ve got a lot of faucets in your house, you will need a 6 GPM flow rate unit. Small houses will be fine with a 1.32 GPM of maximum flow rate.
Tankless water heaters don’t need storage tanks, so they tend to be pretty small and lightweight. However, this can vary from model to model. So, check out which size works out for you the best and go with that one. If you’re thinking about capacity, you should consider the flow rates instead.
· Ease of Use
You should prefer buying a tankless water heater that’s super-easy to use. It should come complete with advanced and smart features that make it user-friendly and convenient.
Features like self-regulation mechanisms, digital displays, and easy-to-use control buttons make these products exceptionally easy to work with. You should also make sure that the device comes with a sturdy heating element and safety features. The best tankless water heaters are the easiest ones to use.
