Four Ways to Speed Up Your Hot Water (Without Installing a Tankless Water Heater)

Despite all of the technological advances that have made our lives so comfortable and convenient, from on-demand movies to smart devices that can be controlled from a handheld computer in our pockets, there are still some primitive situations we have to endure. For example, that seemingly endless time spent shivering in the shower while you wait for the water to heat up. Or that painful moment when you go to wash your hands and water that feels like it’s being pumped directly from the Arctic splashes you.

Waiting for the water to heat up is an age-old problem caused by simple laws of physics: Your water heater is far away from the tap or shower head, and it takes time to flush out the cold water in the pipes. But there are ways to speed up your hot water delivery. The easiest is to install a tankless water heater, but those can cost thousands of dollars to install, and require a lot of space your house may not have. If you want to speed up your hot water without taking on that much of an expense, you have a few more affordable choices.

Install a recirculating pump

One reason it takes a while for hot water to arrive is time: When you turn off the faucet, the hot water sitting in the pipes starts to cool off. The next time you turn on the tap, that cooled water has to be pushed out of the hot water pipes before the hot water can arrive.

To solve this, you can have a recirculating pump installed at a cost typically under $1,000. These pumps are installed on your existing water heater, and work by continuously circulating the water in the pipes so it never sits there, cooling off. Because it’s installed at the water heater, it speeds up hot water to your appliances, as well, including washing machines and dishwashers, which can help them operate more efficiently.

Point-of-use tankless heaters

While a whole-house tankless water heater can be a big and expensive project, what’s known as a “point-of-use” tankless water heater can be a more manageable and affordable solution. These are small enough to install under a sink, and are designed to provide hot water on demand just at that point of use. The heaters themselves typically run a few hundred bucks, with installation typically running less than $1,000. Because of their small size, it’s feasible to install one of these yourself if you’re comfortable with plumbing and electrical work, but they can require careful calibration, so hiring a professional plumber is probably your best move.

Insulate

Since part of the problem with slow hot water is heat loss as the water sits in the pipes, you can sometimes improve the situation just by insulating your hot water pipes thoroughly. This is definitely a DIY job if you can identify and access your hot water pipes, and it’s not a terribly expensive job to hire out, costing as little as $350 on average. It’s just a matter of wrapping the pipes with insulating cuffs, then taping everything off so it’s sealed up nicely. This can help keep water hot while it sits, so the next time you turn on the faucet, you get the hot water you expect.

Adjust restrictors

Cold water has to drain out of your pipes for the hot water to hit your faucet or showerhead, so one possible way to speed things up is to remove any flow regulators/restrictors that have been installed. These simple devices do exactly what it sounds like: They restrict the flow of water, conserving energy and water and keeping your utility bills lower. But since they restrict flow, they also mean it can take longer for cold water to drain off and hot water to arrive, so removing or adjusting them can reduce the time it takes for that hot water to get to you.
