Being able to have hot water on demand is of great interest to many homeowners, especially in those houses where it takes time for hot water to arrive at the faucet. Water circulation or distribution via pumps so that hot water is always present in the piping systems ready for use is the solution that hot Water Recirculation Pumps provide to this challenge. However, should you take the risk of spending on it in your residence? In this article, we are going to analyze the advantages and disadvantages of hot water recirculation pump installation, to help you figure out if it will be suitable for you.
Hot Water Recirculation Pumps ; Explanation.
It is a type of hot water heating pump that allows the user to get hot water on tap at lightening speed as it provides a pressurized system in the plumbing where hot heated water doesn’t have to wait at the turn’s tap. As with conventional arrangements where hot water stands idle and cools in pipes and hence the user has to run water for a few minutes, the recirculation pump returns the heated water into the heater or that remains in the pipes until called for.
The working principle of a Hot Water Recirculation Pump.
These pumps consist of a small electric motor that is used in a rotary pump, to push warm water into your pipes, where it is contained. Depending on the system, some pumps work on a timer and turn hot water on and off in a cycle, while others depend on a thermostat or even a motion sensor, which is a useful feature as it ensures hot water is always ready without wasting water. In houses that do not have a separate return line for hot water, some systems actually utilize the cold water line as a return, which may compromise how well cold water is delivered, but allows for hot water to be available as needed.
Advantages of Installing a Hot Water Recirculation Pump
1. Immediate Hot Water
The most important advantage in fitting the recirculation hot water pump is the instant hot water availability feature. No more sitting near the sink or standing in a shower waiting to be warmed up. Everything from washing dishes to taking a bath, having a source of hot water within arm’s reach can prove to be time-saving and less aggravating.
2. Conservation of Water
A lot of water is wasted every day just by waiting for the hot water to arrive. The installation of a recirculation pump eliminates the practice of running water in order to wait for it to turn hot, hence saving a great deal of water. This can make a great difference, more so in areas which face a lot of restrictions on water use.
3. Energy Savings with the Right System
Some models of recirculation pumps have timers or motion sensors fitted which operate the pump only when needed causing less energy use. When investing in hot waters systems, homeowners can avoid encroaching on their energy saving objectives while achieving the comfort of instant hot water wherever they need it in the house after a few seconds. A timer system or a demand control system will be useful in reducing energy costs due to wastage.
4. Increased Home Value
When interior changes are made to include installation of a hot water heater recirculation system in the covered areas of laying pipes, it positively contributes greater re-sell value of the house. This is also a concern for prospects looking to buy such homes as they tend to be quite large and delay of hot water in such instances becomes a norm. The advantage offered by such hot water facilities may also work to the advantage of your home when seeking for buyers.
5. Greater Convenience
It is quite reassuring to know that one can obtain hot water at any tap without delay. Whether for hand washing, cleaning utensils, or taking a shower, a hot water heater recirculation pump offers more leisure and improves the quality of life.
Disadvantages of Installing Hot Water Recirculation Pump
1. More Energy Bill
One of the disadvantages of hot water recirculation systems is that they may tend to increase the energy costs incurred by a household. Since hot water circulates or is held in readiness, the households overall energy consumption can also be increased. Nevertheless, this expense can be reduced by employing a timer or a programmed system that works only when hot water is required.
2. Installation Costs Raised
The first cost for a hot water recirculation pump is always high provided the system has not been previously fitted in the house, this is more challenging if the house is not fitted with hot water return lines. Where the return lines are absent, piping works can also be needed to install their plumbing system, which raises the price further. There’s more to consider, however, since not only is the cost of the pump to be considered but also the cost of fitting.
3. Effect on the Cold Water Supply may be Experienced
Under some applications where the cold water line also serves as a return for hot water, answering calls for cold water within fixtures is delayed. This is due to hot water left in the cold water line being purged before cold water can come through. This is not a deal breaker for a majority of people but it is certainly a downside that one can think about.
4. Consistent Upkeep
Maintenance is needed for a hot water heater recirculation pump just like any other plumbing system, to avoid operational issues. Poor performance or repairs might result from sediments and wear and tear of the pump. Homeowners ought to be ready for routine checks and sometimes, service calls to ensure the system is functional.
Classification of Hot Water Recirculation Pumps
1. Full Recirculation System
This system requires a dedicated return route that carries back heated water to the heater tank when it’s not being used. It's the best option for big houses with widespread plumbing networks as it ensures the presence of hot water as long as the system is in motion.
2. On-Demand Recirculation System
This type of a system is used when needed only either by a manual switch or a motion system. Making them economical as they only pump hot water when required and thus very little heat is lost and energy not wasted.
3. Gravity-Fed System
In raised systems, hot water is drawn through gravity straight back to the heater without pumping, relying on the weight of the water. This system is often less integrated and works best in homes that have their water heater located under the plumbing system.
Are Hot Water Recirculation Pumps Worth It?
Whether or not to add a hot water recirculation pump to your home system is simply a matter of evaluating the benefits and drawbacks based on your household and lifestyle. If you reside in a vast abode where it takes forever for taps to produce hot water or you are one who abhors the wastage of water, then having such a pump can be a worthy purchase. On the other hand, for instance where you live in a relatively smaller house, or in case you are a bit energy conservation conscious, you may want to choose a more ecologically friendly or use an on-demand water heater.
Some of the elements that should be taken cared of:
Home Size: In cases of higher water usage and long pipe runs, water recirculation pumps are mostly installed in larger homes.
Any Hot Water Usage Patterns: In most cases, household using hot water regularly may see the benefits of having the pump installed regardless of the energy costs.
Energy Consumption Objectives: For such systems, select installed systems which are equipped with sensors or timers.
Summing Up
An instant hot water recirculation pump comes with a number of merits that include provision of hot water without delay, less water wastage, and enhancing comfort in a home. Nonetheless, it is prudent to incorporate factors such as additional energy and installation expenses that might arise. Through a fair assessment of the layout of the house, the usage levels and the costs one is ready to incur, it is possible to establish if a hot water recirculation pump will be useful households.
