We all know it is best to wash our hands with hot water, but waiting for the water to get hot can be frustrating. It wastes a lot of water and seems to always take way too long. Waiting for the water in the shower to get hot; especially when in a hurry, can be equally as frustrating. Not to mention expensive depending on where you live and the cost of water. If you live in places with frequent drought and where your water supply is regulated, wasting that water is not only expensive, but cannot be used for other things you may want or really need it for later. Rheem Taco tankless water heater recirculation pump kits and their accessories allow you to have instant hot water whenever you wash your hands, take a shower, start the laundry, run a bath or use any other commercial, or domestic hot water using appliances by recirculating the water that has sat and cooled. Taco instant hot water recirculation pump systems are small, relatively easy to install, compatible with both residential and commercial Rheem tankless water heaters, and provide instant hot water to the whole house or entire commercial system.

Why Without a Recirculation Pump Do You have to Wait for Hot Water:

When waiting for hot water this has nothing to do with the residential or commercial Rheem or other tankless on demand instant hot water heater you own. Water comes out of the domestic or commercial tankless water heater to your set temperature, this is why they are called instant hot or on-demand hot water heating systems, because they heat the water that you are using as you are using it. However, the water has to travel from the domestic or commercial tankless water heater to the sink, shower or other hot water point of use. The water from the previous use has sat and cooled and has to flow through before you get to the hot water coming out of the residential or commercial tankless water heater.

For example, let’s say you have 10 feet of pipe and 1 gallon of water between you and the commercial or residential water heating system and are going to take a shower using a standard shower head, or a commercial laundry machine with a 2 gallon per minute flow rate. It would take 30 seconds after turning the hot water on full blast to have hot water coming out of the domestic shower head, or commercial laundry machine as it would take 30 seconds for the gallon of water in the pipe from the previous use that has sat and cooled before the hot water from the Rheem or other on-demand instant hot tankless water heater arrives.  Adding a small top-rated Rheem Taco recirculation pump kit will prevent this wasted time and gallon of water. Allowing you to have instant hot water as soon as you turn the hot water heater on at the sink, shower, bath tub, and all other points of hot water use in the whole home or commercial system.   

How Do Standard and Under Sink Tankless Water Heater Recirculation Pumps Work:

The best Rheem Taco tankless water heater recirculation pump kits will save you time, money and prevent frustration by providing instant hot water on demand at every sink, shower, bathtub, laundry machine and any other hot water point of use of the whole home or commercial business. Rheem Taco hot water recirculation pump systems do this by first sending the water left in the hot water line that has sat and cooled back to the Rheem or other energy efficient, on-demand and endless hot tankless inline water heating system where the water is instantly heated to your desired set temperature. The Rheem Taco tankless water heater recirculation pump then pulls the hot water back through the entire commercial or domestic hot water line, where it is ready for you to use.

For recirculation pump kits to recirculate the water throughout the whole house or commercial business you have to have a closed loop system. This is created with either a dedicated return line that starts at the furthest point of use, and comes all the way back to the residential or commercial tankless water heater. Dedicated return line closed loops are required for all standard recirculation pumps. The other option is to use an Under-Sink Recirculation Pump system. Under-Sink Recirculation Pump kits are installed under the sink furthest away from the tankless water heater, and uses what is called a cross over valve to tee into, and use the cold water line as the return line.

The only downside of using an under-sink pump kit to create the closed loop is if someone is using cold water the under-sink hot water recirculation pump will not be able to recirculate the water in the system that has sat and cooled until after the cold water stops being used. If you are in a full remodel or it is new construction adding a dedicated return line and using a standard recirculation pump system is best. If you have a dedicated return line, but recently switched from tank to tankless system and need a recirculation pump you will want a standard recirculation pump that requires a dedicated return line. However, if it is old construction, and you do not have a dedicated return line, but want instant hot water on-demand, the Taco Under Sink Recirculation Pump Kit is the best system to create the needed closed loop for both domestic and commercial applications, and will save you a lot of money not having to tear your floors up and add a bunch of new plumbing.

Timer Recirculation Pumps Vs. On-Demand Push Button Recirculation Pump Kits:

In addition to there being standard tankless water heater recirculation pump kits that require a dedicated return line, and under sink recirculation pump kits that use cross over valves to tee into and use the cold-water line to create the closed loop, you also have different activation options to choose from. Timer instant hot water recirculation pumps are the most common and the cheapest. Timer tankless water heater recirculation pump kits are typically relatively affordable systems, and are easy to use. Simply set up the time for the times of the day you want the circulation pump to activate and the intervals you want it to recirculate hot water throughout the whole home or commercial business at. For example, you can set a small Timer Based Rheem Taco tankless water heater recirculation pump system to activate from 7:00 AM – 8:00 AM and again from 6:00 PM – 8:00 PM every 20 minutes. You can also activate the system on demand at the hot water recirculation pump itself.

The downside of a timer based pump system is you may need hot water during a time you don’t have the Taco hot water recirculation pump set to. Or you may go to use hot water and it is a few minutes before it activates so the water is not going to be at max temperature. Also, the basic timer pump system will recirculate water no matter what during your set times, at your set intervals. Obviously, you will not always need hot water every time it recirculates. This results in a bit of energy being wasted reheating water you are not going to use. The best, energy-efficient Rheem on-demand residential and commercial tankless water heaters are 82% – 95% energy efficient, depending on the model, so the energy used and wasted is minimal, but still with a timer-based Rheem Taco instant hot tankless water heater recirculation pump kit there will be some wasted energy heating and recirculating hot water you are not going to use. The small, top-rated, and relatively affordable Rheem Taco Timer Hot Water Heater Recirculation Pump also requires a dedicated return line closed loop. There is not a timer based instant hot recirculation pump available for domestic or commercial Rheem Tankless water heating systems without a dedicated return line. 

The other type of small and easy to install top-rated Rheem Taco recirculation pump is an on-demand pump kit. Rheem Taco on-demand tankless water heater recirculation pump kits are activated on demand with a push button, motion sensor, or wireless remote transmitter. On-demand recirculation pump kits allow the user to activate the pump system on-demand as needed. With the best on-demand recirc pump system you will always have hot water at your set temperature throughout the whole home or commercial business, and never waste energy heating water you are not about to use. These top-rated on-demand Rheem Taco recirculation pumps are more energy efficient and truly allow for instant hot water on demand at each domestic sink, residential shower, bathtub, laundry or other commercial point of use with simple on demand activation.

Unlike the timer recirculation pump system from Taco that requires a dedicated return line to create a closed loop, the top-rated Push Button Recirculation Pump Kits are available in a standard option that requires a dedicated return line, and an under-sink option that does not. Both the standard push button tankless water heater recirculation pump system, and the under-sink push button hot water recirculation pump kit come with a wired push button for activation. You can add as many small push buttons as you like. As well as motion sensors or wireless remotes, to make activating the on-demand whole house or business recirculation pump kit as simple as possible from as many residential bathrooms, domestic kitchen sinks, or other commercial points of use as you like. Regardless of whether you have or are going to have a dedicated return line and are going to use a standard on-demand recirculation pump. Or if you do not have a dedicated return line closed loop and need to go with a small instant hot under-sink recirculation pump system.
