How to Buy the Best Small Tankless Water Heater

Before you purchase a small tankless water heater, here are a few considerations to keep in mind:

• Fuel source. In most homes, water heaters are fueled by gas or electricity. However, gas water heaters, although quite pricier than their electric counterparts, have lower running cost. On the other hand, electric-powered water heaters, are pricier, but the best for those with small kitchens.
• Gallons per minute rating. This is the rate at which the heater delivers warm water. A tank with 1.5GPM can supply sufficient water for shower and sink usage simultaneously. For people with larger family, go for space saving water heaters with higher GPM.
• Ease of installation. Make sure installation process for the water heater you intend to use is easy to install.
• Size. Since you want an electric water heater that doesn’t occupy a lot of space, go for a tankless version.
• Durability. Here, look for fire safeguards and robust construction.
• Warranty. Considering that you’ll be using your water heater for a long time, you need to go for one with a longer warranty period so you can be covered when it comes to repairs and parts replacement.

With that in mind, you’re now in a better position to choose the right space saving water heater for your home.
