How do tankless water heaters work and why is there a delay in hot water delivery?

A tankless water heater is a water heater without a tank. It has a pretty simple work mechanism. There is a powerful heat exchanger at the core of the appliances. When a hot water tap is opened, the water flows through this heat exchanger, it instantly gets heated, and reaches your outlet as the hot water. Due to its instant heating ability, the tankless water heater is also sometimes called an instant water heater or on-demand water heater.

Now the next question is “why there is a delay?”. Right. So between the hot water tap and tankless water heater, there is a certain distance that water has to travel through the pipe before reaching your tap. So in that sense, the longer the distance, the larger the delay. That makes sense, right? 

Remember that cold water that you initially get on opening the tap? That cold water is the old hot water that got cold laying there and now got pushed out by the fresh hot water.

So now hopefully since you have got a better understanding of how tankless water heater works and why there is a delay. Let’s talk about the two popular and very much effective solutions to get hold of this problem.

It doesn’t matter whether it’s your kitchen sink, shower, or the most distant fixture in your home. Having to wait for hot water can get frustrating over time. In this situation, a small point-of-use water heater installed near the affected fixture and in line with your main water heater can save you peace of mind. 

It doesn’t matter whether you install a tank or tankless model, the role of point of use or POU is to provide you with literally instant hot water. POU units are cheap, costing somewhere 150$ on average, small and compact that can fit inside your bathroom vanity or kitchen sink cabinet and most homeowners can install it themself.

2. Get a recirculating pump system in place

A recirculating pump is a small, low-impact pump installed usually on the top of the tankless water heater. These are small pumps with upto 25 watts of power. And what role it plays is to create a loop between your cold water line and hot water line. 

The function of the recirculating pump is not that sophisticated. It has a thermostatic sensor. When it detects the temperature of water in the pipe has dropped below a certain set parameter then it quickly replaces that water with hot water. There’s always hot water in the pipe. So whenever you open the tap you always get hot water from the very first drop. 

The downside to this system is that you will have a tiny increase in electricity bills. But high-tech models are available that come with wireless remotes and timers which helps with electricity saving.
