Pros:

  • Quiet
  • Works effectively with small-diameter lines
  • High quality, price-performance ratio

The Grundfos up15-42f pump is a favorite amongst the pros since it effectively recirculates hot water at a decent price-performance ratio.

In most cases, a hot water recirculating pump is used in a system that keeps hot water ready for use at all times. If you have a water heater correctly installed, it is likely that you still have a water line connected directly to it. This line is referred to as a hot-water line and needs to be kept at a constant temperature. If this line should drop below a certain temperature, the water-heating unit cannot heat the water to the required temperature and has to delay the start of heating. This results in inefficient use of the heat source, energy that is required for heating is wasted, and the unit may not be able to keep up with the hot water demand.

A recirculation pump is the perfect solution to this problem. According to Grundfos, this pump needs an inlet temperature of just 58F to start and have a maximum temperature of 150F inlet / 160F discharge / 130F static level. This pump can work with most water heaters.

Frequently Asked Questions (FAQ)

What is the best hot water recirculating pump?

Hot water recirculation pumps are typically used for those who are living without natural gas. In these instances, the hot water is recycled from the water heater and pumped back into the inlet of the water heater tank. As the water in the water heater tank is used, hot water is provided from a recirculating system.

This may prove to be a great way to save money and energy: turn down the temperature of your water heater by a few degrees and your hot water usage may decrease as well. The reduced hot water use will reduce the energy costs of raising the temperature back to the desired temperature when the water is used.

What is the best hot water recirculating pump? We researched the hot water recirculating pumps available on the market to find the best pumps available. Here is a thorough list of the best of the best hot water recirculating pump brands.

Are hot water recirculation pumps worth it?

Hot water recirculation pumps really shine when used in conjunction with solar. If you are heating water with solar panels, then it's extremely useful to be able to get that water into the hot water tank from anywhere in the house, rather than the tank only directly above the solar panels.

The problem a solar water system has is that it loses heat between the source and the storage tank. This loss of heat is increased if your water heater is located in a part of your house that is well-insulated. Heat loss can be reduced if your system is set up to move hot water from the solar panels to the hot water heater.

Do hot water recirculation pumps save money?

Perhaps one of the biggest advantages of hot water recirculation pumps is the potential for savings. These pumps decrease your water heating costs by recovering warm water from the bottom of your tank and recirculating it back to the top. The result is that you do not have to completely reheat the water in the tank for an entire day.

The savings are significant, but you have to be careful that you don't set your bath temperature so high that you defeat the point of the pump. A good rule of thumb is to start with about a dunk between your shower and bathtub and add a bit more hot water as needed.

Although they are not a necessity they can be quite useful if you take a bath or a long shower. They can also be beneficial for families with many members as they allow each person to have a bath temperature that is ideal, without affecting the temperature of others or requiring the hot water to cycle through again for every person.

How long do recirculating pumps last?

Recirculating pumps are a great way to save water and money. By circulating hot water, they give you what are essentially hot showers and save up to 30% on your water heating bill. However, one of the biggest questions is whether or not they will last. It’s important to note that they are virtually maintenance-free other than changing the filter, which the manufacturer will recommend every 6-12 months.

So how long do those filters last? One answer we got from a customer was that their filter lasted 7 years, which means his pump lasted a bit longer. However, it’s probably more realistic to expect somewhere around 2-3 years. Many customers say the same thing: the pump lasts them from two to three years, after which time they replace both the pump and the filter at the same time since the filters last longer than the pump.
