Point-of-use water heaters are a great solution when there is no existing hot water source to pull from, or you have a remote location that needs hot water. Point-of-use tankless water heaters are usually installed as close as possible to faucets or appliances that need hot water, and because the device is dedicated to that location alone, you’re guaranteed a steady flow of instantly heated water.

Other Benefits of Point-of-Use Water Heaters

Point-of-use Water HeaterSince most point-of-use water heaters are tankless, you only pay for the energy you use.

They provide instant hot water at a fraction of the cost due to there smaller size and energy requirements. Point-of-use heaters can’t turn the tap off for you, but they can make sure that as soon as you do, no more energy is wasted. These units also heat up much faster than traditional models, so the hot water arrives almost instantly.

It’s important to consider how the fixture being served uses the hot water, and how much demand it will need, when deciding on which type of point-of-use heater to purchase.

Types of Point-of-Use Water Heaters

Point-of-use water heaters come in two different varieties: tankless and tank. The tank type is sometimes referred to as “Instant Hot” because it can supply water hot enough to make coffee or tea.

A small electric powered unit can be installed under a lavatory or kitchen sink to provide said sink with hot water. In these types of installations it is important to make sure the faucet and the heater are compatible regarding the flow rating in GPM (Gallons Per Minute). Some lavatory faucets will need to have their aerators replaced with an appropriate GPM rated aerator ,or the point of use water heater will not adequately heat the necessary volume of water. Other electric models can have small reservoirs that hold a gallon or so of hot water and can be used under kitchen sinks.

The most common use in this application is for a separate water dispenser next to the kitchen faucet. This dispenser can be used to make tea, coffee, or if you just need very hot water. Many models now come in a package that will include the point of use water heater, water dispenser, and filter.

Other point of use water heaters are gas fired and will need to be vented. These tankless water heaters can serve showers, washer boxes, etc.

A key benefit of having a point-of-use water heater at your shower is low energy consumption. This is because the farther the distance between your shower and your traditional heater, the more heat will be lost in the walls of your house.

The California Energy Commission explained that, from the 1970s to today, the distance from the heater to the furthest hot water fixture has increased from 30 to 80 feet, which means it now takes three times longer for you to get hot water from a traditional heater. Point-of-use tankless heaters are installed directly to the shower’s incoming water source, so there’s no lag between source and destination. The only other way to achieve is this with a hot water recirculating system.
