Hot Tub Heater Guide

Hot Tub Heater Guide

As a new hot tub owner, you have to know how to heat the unit in the most efficient way.  You’ll have to choose the right kind of hot tub heater, and ensure you do regular maintenance and upkeep. If you already have a hot tub and want to replace or upgrade your existing heater, you can do that too.

A more efficient heater will ensure your water heats up faster and works more efficiently, which saves you money.

Check out these tips.

Factors Impacting Hot Tub Heating Efficiency

How fast your hot tub heats up will depend on:

  • Ambient temperature (the temperature of the room in which the tub is located)
  • How tightly the cover is placed
  • Condition of the tub’s hardware

Ambient Temperature

Your hot tub will have to work less if the surrounding water and air is warm. In general, 104°F (40°C) is the most you want to go for your hot tub. A good comfort range is usually between 100°F (38°C) and 102°F (39°C).

Cover Placement

You can easily lose heat from your hot tub when you don’t cover it. That’s why you should keep it covered tightly when not in use.

Hardware

A malfunctioning heater or pump, as well as defective jets, can mean the difference between a relaxing time and a stressful one trying to figure out what went wrong. Replace any malfunctioning hardware immediately, and inspect your unit regularly to make sure everything is working properly.

Efficient Hot Tub Heating

Aside from regular maintenance, there are a few things you can do to ensure your hot tub heats up in the most efficient manner.

Landscaping

Sounds funny, but the landscape around your hot tub can make all the difference. Functional landscaping can not only keep heat in, it can block the wind and weather from cooling down or damaging your hot tub.

Wind increases cooling and evaporation, so it’s wise to plant trees and shrubs strategically in your yard, or place your hot tub where it can be protected by vegetation. This will also give you more privacy and cut down on noise. There are also screens you can purchase to place around your hot tub that achieve the same thing.

Insulation

Small leaks in the cabinet can allow heat to escape. Add insulation to the cabinet panels to keep cold air out and ensure your water stays warm.

Leaving Your Hot Tub Running

You may wonder if it’s a good idea to leave your hot tub running. This depends on many factors. If you’re living in a colder climate and use your tub several times a week, it’s probably more cost efficient if you just let it run. If you live in a mild climate and rarely use your tub, shut it down after every use.

Troubleshooting Tips

1.      Water Doesn’t Stay Hot

If your hot tub water doesn’t get hot, there could be a few reasons why.

Sometimes the hot tub heats up OK, but then cools right down after that. Check to make sure the filter isn’t clogged. Clear the debris and clean the filter.

If that doesn’t work, take a look at the thermostat and heat sensors, which may need replacing.

Next, check the tub’s circulation to see if the plumbing has become clogged. You may have to drain and clean the unit, and flush out the plumbing.

2.      Fluctuating Temperature

If you can heat up the unit no problem, then get in and the water gets cool 10 minutes later, you may think it’s just a fluke, especially if the water heats back up soon after. What’s going on? These fluctuating temps could be caused by a failing sensor or the thermostat itself. You will have to replace the offending item.

3.      Not Heating at All

If the water doesn’t heat up at all after you’ve started it up, this could be caused by a low flow in the pump. Replacement may be needed. A failing heating element could also be to blame.
