Should You Replace Your Tankless Water Heater?

Having a tankless instant water heater at home brings an abundance of convenience. These units can instantly deliver a steady hot water supply to your home, no matter when you need it.

But as time goes by, your water heater may start sustaining damage. Many issues concerning the functionality of your instant water heater are easily resolvable with a simple repair, but some cases may require a total replacement.

But when should you toss away your old heater for a new one? Keep reading to find out.

Terrible Water Quality

Your water heater must not only deliver hot water but also ensure the quality is pristine. The slightest contamination can lead to health problems, so consider checking the water from your shower and tap.

Cloudiness, rust, bad smell and taste, and sediments are signs of something seriously wrong with your water heater. This means your unit is not working as it should or has not been maintained.

Consider replacing your water heater if repairs are not doing miracles to your water quality. If you have a new unit and the water quality is still poor, you might want to check the local municipality.

Increasing Energy Bills

Due to cost savings, instant water heaters are considered a better choice than their traditional tank counterparts. Tankless heaters only warm water when the tap or shower is on, which means they use power only when in use.

But if you notice a sudden spike in power bills, consider checking the health of your tankless water heater. Old heaters work twice harder to produce the same output as newer units. 

Strange Noises

Water heaters of any kind must not produce odd noises of all sorts. If you hear popping, banging, crackling, or hissing, this might be a cause for concern.

The root cause may either be a mechanical failure or excessive sediment buildup. Have your unit inspected immediately once it starts making noise to avoid unwanted accidents. Failure to repair may lead to further wear and tear to your water heater.

Alternatively, a replacement is a better option, especially if your unit is old or you are unsure about the extent of the damage. Repairs usually cost 50% more than getting a replacement, plus new units can perform better and require less maintenance.
