Expert Water Heater Repair

Water heaters have a lot of responsibility in any home. They provide hot water for everything, from laundry and dishes to making sure you can finish a shower without feeling like a popsicle. Over time, though, there are a lot of things that can affect your water heater’s performance.

One of the fastest ways to need water heater repair is when sediments form inside your unit. This could be from dirt coming through your water line, but it could also be due to hard water. If you live in an area with hard water, your water heater is highly susceptible.

That’s because of the elements that make up hard water, with calcium usually being a concentrated one. This calcium can harden and clog your water supply. Those hardened sediments can also damage the interior of your water heater, reducing efficiency or breaking it. Another part of your water heater that might need checked is the safety relief valve.

This prevents the water from getting too hot. If your valve gets damaged, your hot water could end up scalding you, so it’s best to have a routine inspection once a year to be safe. Your water heater could also just be getting old and need repairs. This could be anything from a leak to not having enough hot water.

If the repairs are too expensive, we might suggest a water heater replacement, but call Robert Johnson Plumbing either way to get the best!

Avoid Damage by Replacing Your Water Heater!

Robert Johnson Plumbing believes in saving you money and delivering quality. We can handle any water heater repairs you need, but eventually your water heater will need to be replaced. Whether it’s age, damages, or you just want to upgrade, you can get more.

There are a lot of things you can watch out for to know it’s time for a water heater replacement. If your water heater has hard water sediments, your glassware can have a cloudy film after doing dishes. Clothes can also have yellow stains after laundry.

You might notice your water heater making odd noises, water pooling around the unit, or the hot water cutting out. All of these could mean it’s time for a replacement. Of course, you might just want to start enjoying the benefits of modern technology.

Newer water heaters can offer all kinds of positives. You could save with a water heater replacement that’s more efficient. They can last longer and need fewer repairs, because they’re built to be more durable. You might consider tankless water heater installation to save room.

As you can tell, there are a lot of different types of water heaters to think about. That’s why we recommend working with a professional. We can help you find the perfect size for your home, whether you want a traditional or tankless water heater. 

Different water heaters can use electricity or gas as a power source, too. Gas water heaters can run on natural gas or propane. They can last longer and cost less, but electric water heaters are usually better for heating your water. Either way, call us today and let us know what you want!

Save Money Going Tankless!

Whether you need a water heater replacement or want another option to upgrade, you might want to consider getting a tankless water heater. These can be a great alternative to the traditional water heater for a number of reasons.

One of the biggest advantages is that tankless water heaters take up significantly less space. They can also be mounted on the ceiling, wall, or floor to maximize your space. In fact, you can get more than one if you have a larger home or a lot of people in the building. Part of that is because there’s no 50-gallon tank to take up room.

By not having to wait for the entire water tank to heat up, a tankless water heater can reduce your electric bill. Less wasted water can help your other bills and help the environment’s resources at the same time. Something that people love about tankless water heaters is how fast they get hot water. With no tank to heat, they heat water as it goes through the system. Some call tankless water heaters “instant,” because you’ll get constant access to hot water anytime you want.

You won’t have to worry about passive electricity use, because it only functions when you need hot water. Of course, you’ll have to decide if you want a gas or electric tankless water heater.

Our team of professionals can help with the pros and cons. Electric tankless water heaters are usually better with the heating efficiency, but they use a lot of electricity. Their gas counterparts can last longer and cost less, so it’s really up to you.

Either way, let us help with your tankless water heater installation when you call today!

Boiler Replacement and Installation

Having the right boiler in your home can make a big difference in your comfort. It can also play a role in the heating efficiency, which can affect your electricity or water bills. Whatever the case, it’s important to hire a professional for the best results. There are different sizes to your boiler, and choosing the wrong one can reduce its lifespan and how effective it is.

We’ll help you choose the right one based on the size of your home and how much heat you use. Boilers, like most major appliances, are designed to last for a while. However, they all get old and your boiler is no different.

You might be spending more on frequent repairs than you would by upgrading to a new boiler. You might even get more efficiency with modern technology. Aside from old age, you can be on the lookout for any strange noises coming from your boiler. 

You might also notice water near the base of your boiler, which could mean leaks. Some of these issues can be fixed with a repair, though some can’t. Another way to know is by scheduling a routine inspection. 

No matter how you want to go about it, Robert Johnson Plumbing will help you with your boiler installation. From removing the original boiler to connecting the new one, our experts are here to help when you call!
