Recirculating hot water pumps are a great way to save money on energy. They can also help you avoid the hassle of re-routing existing plumbing to get hot water at your sinks and faucets. If you’re interested in saving time, money, and energy by installing a recirculating pump, here’s everything you need to know!

Your water heater is the single largest energy source in your home.

Your water heater is the single largest energy source in your home. It accounts for 30% of your home’s energy bill and even more if you have an old one that doesn’t meet today’s standards.

You can save money by using a recirculating hot water pump which circulates hot water through the pipes in your home to keep them warm and reduce the heat needed to reheat the whole system when you need hot water. The pump uses about half as much energy as conventional systems do, saving up to 40% on heating costs!

A recirculating hot water pump can significantly reduce the time it takes for hot water to reach your tap - and save you lots of time and money in the process.

According to the U.S. Department of Energy, families waste between 400 billion to 1.3 trillion gallons of water while waiting for hot water. Each family wastes over 32 gallons which costs over $1,000 a year. The EPA (Environmental Protection Agency) advises. “We can all use at least 20 percent less water by installing water-efficient fixtures and appliances.

Recirculating hot water pumps are the solution to these problems. They use less energy than conventional tank-type systems and can be installed in minutes without requiring plumbing.

How does a recirculating hot water pump work?

The pump uses electricity to heat your hot water as it circulates through your pipes – meaning that when you turn on the tap, it gives you ready-to-use hot water! This means that you don’t have to wait for cold water from your tank or cylinder to run out before you can get at what’s underneath it all – there will always be one continuous stream of hot water flowing from the tap straight into your hands. 

You save time by not having to wait for cold water for it to reach its maximum temperature. Additionally, recirculating pumps cost less than replacing an old broken-down tank system with another one (in addition).

The Hot Water Pump sends water from your tank-type water heater back through the hot water line, then back to the heater.

This is where the hot water pump comes into play. The pump is connected to the hot water line, which then sends water from your tank-type water heater back through this system, and ultimately back to the heater.

The pump can be installed in a few hours by an experienced plumber for an estimated price around $200. Proper maintenance and care should last for years before needing replacement.

When you turn on a faucet, instead of waiting for cold water to run out and be replaced with hot water, it already has hot water waiting.

When you turn on a faucet, instead of waiting for cold water to run out and be replaced with hot water, it already has hot water waiting. This saves time because you don’t have to wait for the water to heat up. It also saves money on energy bills and plumbing costs and helps the environment by reducing the demand for gas or electricity from your heater.

Recirculating pumps are small devices that circulate existing hot water through your pipes so that it’s always ready when you need it at the tap. All they require is an electrical power source (a wall socket) and access to the incoming cold-water pipeline at least once every two hours or so—typically just before use or during use if possible. This access maintains adequate pressure levels to prevent leaks due to insufficient flow rates coming back into circulation after being used elsewhere around your homes such as a kitchen sink or bathroom tub/shower combination set-up.”

This means you save money on electricity, gas, and energy use.

  • Reduce energy costs. A recirculating hot water pump can reduce your utility bills by 25-50% over the life of a water heater. This is because it will use less electricity, gas, and overall energy than standard electric or gas-fired systems.
  • Reduce time to get hot water. A recirculating system eliminates the need for an immersion heater in some cases, so you will get hot water immediately after turning on your shower or faucet without having to wait for it to heat up first.
  • Eliminate a second tank (and its associated plumbing). Many homeowners install a tankless system that heats only as much water as needed at any one time; however, these systems require an additional storage tank outside of their home which can add clutter and expense. Recirculating systems are often installed with only one indoor storage tank instead of two—saving space and money!

You also save money by not having to buy additional piping or re-route any existing piping.

  • No need for new pipes
  • No need for additional plumbing work
  • No need to re-route any existing pipes

Saving money while conserving energy is easy with a recirculating pump.

If you’re on a mission to save money and conserve energy, consider installing a recirculating hot water pump.

A recirculating pump can reduce your utility bills by up to 30%, which amounts to about $50 per month for the average household. It also saves up to 25% of your home’s hot water energy use with its high-efficiency technology, which means your water heater will last longer as well.

What’s more? You’ll save time in the process! A typical installation takes less than an hour and has no messy drilling or plumbing required; once installed, no additional parts or maintenance is needed. Plus, with pre-set temperature controls that match most showering needs (up to 100 degrees Fahrenheit), there’s no need for constant monitoring either.
