Tankless Water Heater

The most common types of water heaters are tankless water heaters and tank water heaters. Both are great at delivering hot water to you and your family members, but let’s talk about the basics so you can decide which of these two is better for your household.

When it comes to these two models, tankless water heaters are newer and have been introduced as an amazing energy-efficient alternative. If you haven’t heard of them before, you can always opt for an informative buying guide to uncover some more useful information. Now, you have probably figured out by now that this model doesn’t utilize a tank to hold heated water.

The question is, where does the hot water come from then? Well, these heaters don’t hold water in reserve. Namely, they do it as soon as you decide that you and your appliances need hot water.

As soon as you turn the tap on, the tankless water heater will start heating water to the temperature that is most convenient for you and send it directly to the outlet. Additionally, it only employs energy when hot water can be guaranteed.

A lot of people call them on-demand water heaters as well because they heat the water only when you ask for it, instead of pre-heating it for storage. Just like tank models, these are also run by electricity or gas.
