TYPES OF BEST HOT WATER RECIRCULATING PUMPS
To help you decide on the best type of hot water recirculating pump to use, check out how each type differs from one another.
- Traditional Hot Water Recirculating Pumps
The traditional hot water recirculating pump system has its own return line. This connects the hot water pipes to the bathrooms and faucets, and then back to the water heater. The recirculating pump pulls the water from the fixture and into the water heater in order to create a loop. The pump’s hot water loop keeps the hot water accessible in the tap whenever you need it since it is kept warm in the hot water pipe.
There are also some traditional hot water recirculating pumps that include a built-in timer. This way, you can customize the working hours of the pump to save energy costs.
- Instant Hot Water Recirculating Pumps
Unlike the traditional hot water recirculating pump, the instant hot water recirculating pump does not need a dedicated line to make a loop. This makes this pump system more ideal for some households and buildings since it is easier to install. In fact, this type of hot water recirculating pump can be installed on any kind of house. It can come from an over the water heater, or from under the sink.
Over the water heater- The pump is installed above the water heater while the check valve is installed far from the hot water heater under the sink. This setup creates the needed pressure to push the hot water into the water pipes.
Under the sink- The pump is installed far from the water heater under the sink. It pushes the hot water to the cold line to be accessible in all water fixtures.
- On-Demand Hot Water Recirculating Pumps
Quite similar to the instant hot water recirculating pump, the on-demand pump is activated by its user. Once activated, it pushes the cold water to the hot water pipes then back to the cold water pipe and into the water heater. This creates a temporary loop to heat the water and become accessible in the entire house. This can be really cost-efficient though you still have to wait for the water to heat up.
HOW TO INSTALL A HOT WATER RECIRCULATING PUMP
When all you want is to enjoy some hot water but you don’t have the time and strength to prepare it, fret no more. Perhaps it’s about time you embrace the innovation that a hot water recirculating pump can give. With a hot water recirculating pump in your house, you don’t have to bother heating up some water on your stove anymore.
- All you have to do is install one, activate it and enjoy a hot water in the kitchen or in the bathroom. So, we already prepared some tips below on how you can install one in your house.
- Turn off the cold water pipe that connects to the water heater which is commonly installed on top of the water heater. Then, turn on the hot water fixture to check if the flow really stopped.
- Cut the flexible hot water supply which is connected to the hot side of the water heater. Be prepared to catch the residual water that will spill out of the pipe when cut.
- Set up your pump on how many times you want it to run using a programmer. The timer will automatically set the pump to work when you needed it the most.
- Screw the hot water pump to the hot side of the water heater where the hose is located. Make sure that the timer faces the direction where you can adjust it easily. You can use a plumber’s tape to tighten it down unless there’s already a rubber gasket in the pump fitting’s female nut.
- Connect the hot water line on top of the recirculating pump then tighten it down with a channel-type plier. You can also loop the flexible lines if needed then open the cold water pipeline again.
- Now, proceed to the sink that is installed farthest from the water heater then install the check valve. Be sure to turn off the water supply on both the hot and cold water supply using the valves under the sink.
- Screw the two water supply tubes from the sink to the outlets on top of the check valve. Take note that the hot water is on the left and the cold water is on the right outlet. Now, run the water on both tubes from the check valve to check if you’ve got the right ones.
- Once you’ve tightened down all connected tubes, mount the check valve on the wall. Use the provided screws included in the installation kit.
- Run the water on both lines to remove all the air out and check them for leaks or loose connections.
