How Does A Hot Water Recirculating Pump Work?
At first, we need to make clear how this machine is actually working, so you will be able to understand the whole process.
You have probably experienced a scenario when you want to have a warm shower, but when you step into the bath and open the water, you are waiting for hot water to reach you.
When you are waiting for the hot water, there are many gallons of cold water flushed down by the drain and being unused, and if you calculate how much water you waste daily, you would be impressed.
There are defend types of these pumps too, and it depends on where they are located.
They can be at the water heater directly, at the point of use and they can be tier aquastat drove or demand and aquastat.
Hot Water Recirculating Pump Types
Pump At The Water Heater
The first option is pump being put by the water heater.
This kind of installation is not suitable for all types of plumbing because they are appropriate only for installation with pre-installed hot water return line.
How does it work?
We first have the main hot water line which needs to be primed with hot water and it needs to be done correctly so this hot water doesn’t push any hot or warm water to the cold water supply.
Hot water supply is also divided from the main supply in order to keep individual fixtures not hot and that means there will be a delay (short one) while this water gets purged when the hot water tap is being turned on.
You will be able to see this kind of installation more in the new buildings.
Pump At A Point Of Use
If you don’t have a return hot line, this option is suitable for your installation because here you have pump located under the point of use and that means it can be installed directly under the sink.
With this type the machine, the non-hit water is returned to the cold water supply to the moment when hot water is sensed at the fixture.
In this cas, the water is not being returned by the hot line but by cold line instead.
And what is the good side of the pump of the point of use?
The hot water has a really short way to the fixture, and that means you will be able to get your hot water almost instantly.
You can install this type to almost every building because you don’t need a return line.
With this two options, you can also choose timer and thermostat mechanism, or you can go with the ‘’on demand’’ option.
Timer / Aquastat Driven Systems
Timers and aquastats are great if you would like to get your water hot in the plumbing at certain times of the day.
You just need to set the timer, and the water will start heating up.
For the most efficient operation, we have this two (timer and aquastat) working together.
Why do we have a timer?
You probably don’t need hot water every second of the day, but you usually need it in the morning (Showering) or in the evening and wouldn’t it be nice if you had water ready for you to jump into the shower?
With thermostat that is possible.
You only need to set up the time when you want to have hot water, and that is it.
Through the day we have active and inactive time and while active time the pump will be working so the water is always in the right temperature zone.
The pump will shut down when the temperature is right.
They don’t run all the time!
That is why we have those aquastats because thy notice when the water is at the set temperature and then gives the signals to the pump and the pump will start working again.
If you have set the active hours, that will only happen within that hour range.
On Demand Systems
The other option is on-demand systems, and you cannot be as passive as you can be with timer ones.
You will need to activate the pump if you want to have hot water and when you activate it, you will have hot water pumped out from the heater and the cold water will be sent to the cold water side.
If you have circulating pump located under the sink, you can activate it there, or you can activate it at different locations in the building.
The pump will shut down when the hot water reaches the pump, and the circulation is being shut off before the cold line is fully filled.
There are also different technological hacks like you can set the control switch into the bathroom, and you can set up motion controls, and whenever someone enters the bathroom, the pump will start to prepare hot water.
This kind of pumps can be really efficient because the water is heating up only when you really need it and that means there is less loss and that means you are doing something great for the environment too.
I hope this article helped you at least a bit at your understanding of how hot water recirculating pumps work and now you will be able to think about getting yourself one too.
You need to have in mind that these devices save up a lot of water and when you save up water, you save up money.
Less water loss means you are doing something great for our environment too.
