What is a Tankless Water Heater?

Tankless water heaters are units designed to instantaneously heat water and make it available whenever we need it. They are also known as on-demand, continuous flow, flash or inline water heaters. As the name implies, there is no tank installed in a tankless water heater, and they do not store hot water like the conventional tank water heater models.

With a tankless water heater installed in your home, you will continuously have hot water as long as there is a need for it. Though they may be more expensive upfront, they are ultra-efficient units that will improve your energy savings as well as make hot water available on demand.

Design and operation of the tankless water heater

The tankless water heater is designed with flow sensors that activate the heating coils whenever water flows through them. As water flows, it circulates through the copper heat exchanger and eventually heats to the desired temperature before it will be discharged through the faucets and other water outlets.

The heating coils and exchangers are protected from water that is highly acidic by coating and surface treatments. The energy sources for the tankless water heater can be electric, natural gas or propane and solar.

Point of use and central tankless water heater

Based on your preference or need, you can choose to install the Point of use (POU) or the Central tankless water heater. The POU water heaters are installed at the outlets – in the bathroom or kitchen and can instantly provide hot water when the need arises, thereby saving more energy.

The central tankless water heaters are installed with supply pipes to the outlets and can result in water wastages. However, you’d need the expertise of a plumber at Just Water Heaters, to determine the right water heater for your household.

The two categories of tankless water heaters

There are two categories of tankless water heaters based on heating capability. They are:

Full on/full off tankless water heaters

This type of water heaters is designed to consistently heat water no matter the flow rates. It doesn’t have variable power output levels but can be controlled manually.

The modulated tankless water heaters

The heat output of the modulated water heater is determined by the flow rate of water running through it. This type of water heater can maintain the temperature of water usually at the range of ±2°C no matter the changes in flow

The advantages of tankless water heaters

  • Energy efficiency and savings
  • A continuous flow of hot water
  • Highly compatible
  • Reduced risk of water damage
  • Easy to winterize
  • Highly efficient and lasts longer than the conventional tank types

Installation of tankless water heater

Tankless water heaters can be installed efficiently by professionals because the process is a bit complex. For electric units, it needs to be integrated with the wiring and circuit breaker panel of your home. If you want to install natural gas or propane power units, the venting, gas connection and other factors must be considered.
