How do tankless water heaters work?

If there is not enough hot water to go around in your household and you are having to wait to get it to the right temperature, you should know that there is a solution to this problem that can benefit you both practically and financially. Tankless water heaters heat up your water only when you need it, which is different from how regular tanks work. As well as our gas stoves & wood fireplaces in Victoria BC, we also sell and install this different type of heater. So how exactly do they work? Before we answer that, first we’ll look at how regular water heater work.

Regular water heaters keep the water heated constantly

Standard ones create standby heat loss, which refers to the energy that is being used to keep water at a steady temperature even when it is not being used. The tank holds the water and heats it on a continual basis. This is inefficient and is one reason you may want to switch over to on-demand hot water.

Tankless water heaters raises the temperature of hot water by using a heat exchanger

Heat exchangers can be found in refrigerators, car radiators, and air conditioners. What they do is transfer heat over to a different source from where it began. To create on-demand water, a heat exchanger transfers heat from an electric coil or a burner that is gas-based to wherever the water is coming out of, such as your kitchen tap. The water circulates through the exchanger when you turn on the tap and proceed to become heated to whatever temperature you set it to.

There are two types of tankless water heaters to consider

First, whole house heaters, as the name implies, can be used to heat every source of water in your home and they allow more than one source to be in use at a time. This can understandably be complex to setup and expensive to both install and maintain.

The other type is a point-of-use heater, which is smaller and can be used for one or two outlets. These are so small that they can fit right under the cabinet where the water comes out of, which is beneficial for lowering the amount of time it takes for the heated water to come out.
