You hop into the shower and quickly jump back out again because the steaming water you were promised is nowhere to be found. If that’s the case, it may be time for a new hot water system. And as long as you’re in the market for one, consider a solar water heater.

If you don’t know much about them, you may be hesitant to get a solar-powered water heater. (How much do they cost? How well do they work if the sun’s not shining?) But solar hot water systems can offer plenty of benefits to homeowners. You may find that buying one is a worthwhile investment for your home. Here’s what you need to know.

What’s a Solar Water Heater?

At their most basic, solar heating systems act as greenhouses for water. The technology isn’t new; the first system was patented in 1891. Systems have improved since then, and today, they use a set of solar panels — known as a solar collector — that trap heat. This heats the water, which is then stored.

When deciding on a solar hot water system, you can choose between an active system and a passive system. The main difference is that active systems have a circulating pump and controls. Passive systems tend to be less efficient, but they are less expensive and often last longer. An installer can help you determine which type works best for your home, water needs and location.

Is a Solar Water Heater Worth It?

The answer to this question is always going to depend on your individual circumstances, but most people find a solar water heating system is a good investment. If you’re trying to build a more eco-friendly lifestyle, solar water is a great addition to your home as it decreases your carbon footprint.

Even those not interested in going green for the environment find that a solar system helps give them more green financially by putting more money in their pocket. Although upfront costs can be high, these systems pay for themselves over time by reducing your energy bills.

However, solar hot water systems aren’t without their disadvantages. Your potential savings can differ depending on where you’re located, and some homeowners have to pay additional costs to prepare their homes for the systems. It’s important to understand both the pros and cons of installing solar hot water before deciding if it’s right for you.

What Are the Benefits of Solar Hot Water?

Cost Savings

The U.S. Department of Energy estimates that 19% of a household’s energy use goes toward heating water. In most homes, it accounts for the second-largest energy expenditure behind space heating. But once you have solar hot water installed, it doesn’t cost anything to heat the water because using the sun is free. The exact amount you can expect to save depends on a number of factors, such as how much hot water you use and where you live. However, the says that the average U.S. household saves 50% to 80% on their water heating bills after installing a solar hot water system. You’ll also be protected if there are fuel shortages or rising energy costs in the future.

Increased Home Value

Homes with green features are becoming increasingly popular, so solar hot water can help your resale value. It’s likely solar hot water will add value to your home when you’re ready to sell as buyers continue to look for energy-saving and environmentally friendly housing options.

Tax Credits

Currently, homeowners can get a federal government tax credit for the cost of materials and installation of a solar hot water system. The credit is 26% for systems installed before the end of 2022, which can help offset the initial cost of the system. Keep in mind that some states have additional credits available that can lower the cost of the system even further. The credit is only available for systems that heat water in your home, not those used to heat pools or hot tubs.

Environmentally Friendly

Solar hot water systems have a gas or electric backup system for overcast days, but most of your hot water is heated using 100% renewable energy. This means you’re lowering your household’s carbon footprint and keeping greenhouse gases out of the atmosphere.

What Are the Disadvantages of a Solar Water Heater?

Upfront Costs

HowMuch.net says the average cost of installing a solar hot water system is $4,120, but exact prices depend on the type of system and where you live. According to HomeServe data, replacing your old water heater with a regular, tanked model costs $1,741 on average.

There’s definitely a premium for installing solar. However, tax credits can help lower the costs. And according to Energy Star, solar hot water systems often last longer than traditional systems, so you can delay the cost of a replacement system.

Roof Space

Solar hot water panels are much smaller than solar electricity panels because they’re more efficient at converting sunlight to heat. Despite this, you do need room on your roof for the system. That space needs to be oriented in the right direction and can’t be covered by shade from trees or taller buildings. As the systems can be heavy, they may not be suitable for older houses. Or, you may need to reinforce the roof so it can hold the weight.

With all these considerations, you may find it hard to find an appropriate space for a solar water system. Installers are generally happy to visit your property to determine if a system will work for you.

Less Efficiency on Cloudy Days

Solar panels can generate heat on cloudy days, but you may find the system is less efficient in certain types of weather. This is especially true in northern states that get less sunshine during winter. The majority of systems have boosters that provide hot water when the sun isn’t up to the challenge, so you don’t need to worry about cold showers. However, you may have fewer financial benefits if you live in an area that lacks sunny days.

Maintenance Costs

All hot water systems need to be maintained, whether you’re flushing the system or checking the valves. However, solar systems can be more difficult to maintain yourself due to the nature of the parts. It can also be harder to find someone to do maintenance than it would be if you had a traditional system. You should keep these future costs in mind when making your decision.

During a storm, your basement is often the first place in your home to flood. Keeping it dry protects the rest of your home and possessions from water damage. You make even keep some of your most important possessions in the basement — like irreplaceable photos and important documents — which makes it even more important to have a working sump pump.

How well you maintain your pump will impact how long it lasts — and whether it’ll be able to run properly when you need it to. Here’s a maintenance checklist you can use to extend your sump pump’s life and keep your home dry.

How Many Years Does a Sump Pump Last?

If you’re performing routine sump pump maintenance, you can expect to get up to 10 years out of your pump before you need to replace it. There are some factors that can reduce the life of your pump, so if you don’t test and repair it when you need to, you may find that it has a reduced operating life. Simple things such as not making sure that the pump is on an even surface and in an upright position may force the pump to work harder and for longer than it should. Accumulated debris inside of the pump pit, basin, discharge line and other operating parts can also damage the sump pump and cause it to malfunction.

Do Sump Pumps Need Maintenance?

You should perform sump pump maintenance at least once a year. Consider performing maintenance checks more often if you notice that it’s working more than usual because of an unusual accumulation of rain, snow or moisture due to the weather.

Preventative maintenance is less expensive in the long run than an early replacement. You run the risk of severe flooding if your pump can’t clear water from your basement as quickly as it accumulates. You should factor in the cost of repairing water damage to your home if this should happen. Some insurance companies might be resistant to pay claims if you didn’t perform regularly scheduled maintenance.

How Do You Test Your Sump Pump?

The easiest way to test whether your sump pump is working properly is to pour some water down the pit and see if the pump turns on. This is a great way to see how the entire system is operating because you can run outside and check the discharge line for signs of blockages or debris that has built up inside the pipe. Pay attention to where the water is exiting your home and the direction of the runoff.

You may need to make adjustments if the water is running onto your neighbor’s property or back toward your home. It’s a good idea to perform this test once a month so that you’re aware of any problems and can clean or repair your sump pump if necessary.

How Often Should You Clean Your Sump Pump?

You should clean your sump pump whenever you notice a buildup of debris or a change in how well it performs. Most of the time, you can resolve any issues by cleaning the components and locating the source of the obstructions in the system. If you clean your sump pump thoroughly and still notice that it’s not working properly, it might be time to have it repaired or replaced.

How to Perform Sump Pump Maintenance

You can maintain your sump pump yourself most of the time. Follow these easy steps to make sure that your pump is set up correctly and that all the components are free of debris:

• Check that the pump is positioned correctly. Your sump pump works properly when it’s on a level surface and upright. If it’s leaning or the floor is not even, water won’t flow into it properly and the pump may have to work harder to clear water, or it may be unable to pump out any accumulating water.
• Remove the cover and look inside. You might be surprised by what you find inside of the sump pump, but you can often clean out the debris by spraying the basin and internal components with a hose.
• Check the drainage line. Some clogs can be due to a frozen line or natural debris buildup. When you check the pipe, also make sure that it’s connected securely to the sump pump.
• Inspect and clean the inlet screen. The inlet screen is another common place where debris and gunk can accumulate and clog your pump.
• Make sure that the float is working. One way that sump pumps die quickly is by being overworked. If your float isn’t functioning, the pump may activate when it doesn’t need to, and the engine can wear itself out from running all the time. It could also keep the pump from turning on when it needs to drain water from your basement.
• Test the pump. Using the method mentioned above, give the sump pump a test to make sure that it’s activating properly and moving water out of your basement.
• Make sure that the pump has multiple power options. After making sure that the pump has a power source, consider that it may rain or flood when your home doesn’t have power. You can buy a backup battery or a generator to ensure that your pump can work during an emergency that knocks out the power.
• Consider having a backup sump pump. If your primary pump fails for any reason, having a second pump on hand can prevent basement flooding and minimize the damage done to your home in a flood.

If you’ve tried all these things and find that your pump isn’t working properly, the final step is to call someone that knows how to repair or replace your pump.
