Heat is lost when water transfers from the central hot water hub to the shower, faucet, or appliance it supplies. When the water distribution system requires more assistance, residents might consider getting a point-of-use (POU) water heater. A POU water heater heats water closer to the shower, sink, or bathtub where the water is flowing. It's called "point of use" because it heats the water at the point where it is being used rather than using the central heater. While the need for heating water at home is not much of a decision, using a point-of-use water heater does come down to choice. We'll share our thoughts on when a POU water heater makes sense and when it may not.
Small homes
Setting up multiple POU water heaters in a smaller home rather than having a centralized water heating system can save on your energy and utility bills. A POU heater costs roughly $300 versus the $900 to $5000 price range that accompanies traditional and tankless water heaters. Some tiny homes that already use a water heater could consider switching it out for a couple of POU heaters. First, ensure that the heat capabilities align with household usage.
Hot tubs and add-ons
Home additions that need an additional water supply, like hot tubs and small or outside bathrooms, can benefit from installing a POU water heater. Hooking up home add-ons to a POU heater and a cold water line solves getting water where it needs to go and heating it at the location. This handy unit is a low-cost way to prevent potentially expensive plumbing work.
Distant fixtures and appliances
Homeowners can install POU heaters near showers, sinks, washing machines, or dishwashers further from the central heating system. The decentralized heating unit will keep appliances and fixtures supplied with the hot water they need and not run up a high energy bill.
Not suited for high demand
Consider a POU water heater as a tiny heating device that aids in limited spaces or areas where a larger unit is unfeasible. POU water heaters cannot meet large home appliances' energy demands. In addition to not being the go-to for high-demand hot water, POU heaters should not be considered a reinforcement for geothermal pumps or solar heating.
Should you purchase a point-of-use water heater?
Installing a POU heating system can save on water and electric bills while also getting fast heat to the point where it is needed. However, consult with a professional to see if a POU water heater is a good choice for your home.
