Traditional & Tankless Hot Water Heater Solutions

The cost of a brand-new water heater can vary widely depending on the type & size (in gallons) of the water heater. Prices can also vary considerably between the two types of water heaters: traditional tank & tankless. In addition, there are several other factors that can affect the overall cost of a water heater installation or replacement:

What’s the Difference Between a traditional tank Water Heater & a Tankless Water Heater in Dublin: A traditional tank water heater stores gallons of water, so hot water is always available. A tankless water heater will heat up water on-demand, which will save you money in energy costs down the road. Traditional storage tank water heaters are much easier & cheaper to install.
Is Gas or Electric a Better Fuel Source: This decision can be heavily dependent on your geographic location & local natural gas and electricity costs. However, it’s generally a bit more expensive for a gas water heater than an electric water heater.
What Size Water Heater Does Your Dublin Home Need: Traditional tank-style water heaters can range from 20- to 80-gallon tanks, with 40-gallon being the most common. Keep in mind, the larger the tank, the more costly will be for the unit itself & the heating costs. Let the plumbing experts at CastleWorks Water Heaters of Dublin help you decide which option is best for your home with an installation evaluation & cost estimate today!

No matter what your hot water needs are, our expert plumbers will determine the best water heater type & size for your home with professional advice on your installation before any work is done. You’ll know exactly what solution is best & most affordable for your new water heater; that’s our guarantee.

Nam Park was an excellent technician. He was patient and thorough. He was very careful with the house and wore protective booties until he put down blankets. He updated me regularly and worked expediently. Would highly recommend.

Miguel was the technician that arrived within a few hours of my call to check on my water heater. He quickly assessed the situation and provided me options. I decided to go with a new water heater and he had it installed in just a couple hours. I was able to give my toddler a warm bath before bedtime!

On Sunday November 8 our water heater broke down and also had a bursted pipe. We called CastleWorks Water Heaters and they made sure we turned everything off properly and set up the water drain system correctly. Within 90 minutes a technician named Erik Vargas arrived, and let me tell You -- this Guy was fantastic! Erik went through all of our options and explained everything perfectly and then went to work installing our new Water Heater. After the technician Erik left our garage looking better than it ever has. CastleWorks gets a rating of💯👍🧑‍🔧 from us. W.P. Biagi
