Save Space in Your Old Columbia Home

Traditional tank water heaters take up a lot of space – in your home, on your utility bill, and with your time. A tankless water heater replacement takes up less space, saves you money in the long run on energy costs, and needs much less maintenance than a tank water heater. Plus, it has a lifespan as long as 20 years.

If you’re replacing a tank water heater with a tankless one, installation can be a big job.

Tankless Water Heater Repair Services

A tankless water heater can last well over a decade. If you have an emergency with your heater, make sure to choose a plumber who won’t try to upsell you. We’re familiar with all of the tankless brands, so you don’t have to worry that you’ll call and be turned away.

Tankless Water Heater Maintenance Services

The Midlands sits on mineral deposits, which makes hard water a common issue. If you have hard water, you’ll need to flush your tankless water heater at least once a year to keep it in good condition without sediment buildup. Kay Plumbing can help you decide on a good maintenance schedule for your heater, and we’ll come out to flush it for you, too.

Never Lose Hot Water in the Middle of Your Shower Again

When a tankless water heater is sized correctly for the maximum usage, it can give you practically infinite hot water. Start the dishwasher and take a long, relaxing shower before bed without worrying about the dish cycle or your wind-down time being ruined.

Kay Plumbing will install your tankless water heater correctly, and help you figure out how often it needs to be serviced to maximize its lifespan. If something goes wrong, we can come out the same day you call – even if it’s after hours.

Frequently Asked Questions

Is a tankless water heater better than a tank water heater?

Ultimately, whether a tank or tankless water heater is better depends on your situation. If you’re building a new home or renovating, it might be easier to install a tankless water heater. If you’re replacing a tank water heater with a tankless one, you have to be ready for a high initial investment and long-term return.

How often should I have maintenance done on my tankless water heater?

Your tankless water heater should be serviced and flushed every year.

Can I service my tankless water heater myself or do I need a plumber?

If your tankless water heater needs to be flushed or cleaned, it’s best to call a plumber. This will allow you to be sure everything stays in working order and that it’s serviced correctly.

My tankless hot water heater isn’t working. Can I fix it myself?

If your tankless unit is having an issue, it’s best to call an expert. There are a lot of working pieces in your water heater, as well as concerns like making sure it’s not receiving power. A professional plumber can make a simple fix in no time.

Will my tankless water heater work in the cold?

Tankless water heaters can work in temperatures below freezing. For most of South Carolina, that means temperature won’t be much of a problem when you need to heat water. If you’re worried and it’s very cold out, run multiple faucets in your home at a drip so water continues flowing through the pipes. You can also winterize your unit.

What type of tankless water heater should I get?

You should choose what type of tankless water heater you get based on whether you want it to be electric or gas powered, how much water you expect to use, and factors like your budget.
