Water heater accumulators are neat little devices that can help your home’s hot water system perform better. They can save you water, energy and money! Let’s find out how they work and why you might want one of these in your home.
A water heater accumulator at home isn’t without its benefits. One major advantage: It could save you water. Hot water may not come out of the tap immediately when you open it. There can be a lot of water that rolls down the drain during this wait. But with a water heater accumulator, you already have hot water waiting for you, thus you are not running as much water down the drain!
It can also save energy, another good thing. It can use a lot of energy having your water heater heat all that water at once. But aided by an accumulator, it can warm smaller amounts at a time and thus do so more efficiently. This can also help save you money off your electricity bills!
A water heater accumulator is simply a small tank that stores hot water. It hooks up to your water heater, which heats your water and holds it there for later use. So as soon as you turn on the hot-water tap you have hot water from the accumulator so you don’t have to wait. That way you never have to be without hot water!

Size definitely matters when choosing a water heater accumlator. You have to pick one that suits your family. If it’s too small, you could exhaust your hot water supply in short order. But if it’s too large, you may be using more energy to heat more water than you really need. There are professionals you can consult who can assist you in choosing the right sized one for your home, from your local plumber to a water heater expert.

You can also use a water heater accumulator to increase the water pressure at your home. Water pressure may also decrease at times when you are using water in other locations simultanously. But with an accumulator, water pressure remains constant, meaning you get a strong flow of water no matter where you are in your home.

Like everything else, a water heater accumulator requires care to function well. You'll want to inspect it for leaks, clean it regularly and keep it maintained. With proper consideration, your water heater accumulator can give you the full benefits it offers and last a long time to come.
