"Wanda?s is awesome! My old electric hot water heater tank finally retired to the recycling bin. I called on Tuesday evening and spoke to a knowledgeable technician named Chad. I told him what my old unit was doing and he said it definitely needs a replacement after 17 years. He then asked how the home is heated. And then gave me the 2 options for my home. He patiently explained the differences between the hybrid heat pump unit vs the electric one that was presently on its way out. He answered all my newbie questions. He explained the pricing between the two units. I told him I have to discuss everything with the cfo and I would call back Wednesday morning. He also told me they would get me on the schedule for tomorrow or the next day. That was amazing. I called the next day and spoke with Amanda to schedule me in the following day. Chad showed up the following morning and did an awesome job. He was very polite and knew his job well. I am very satisfied so far with Wanda?s."

"These guys are the best! They taught me so much about my home HVAC system, both the pros and cons. They take so much pride in the results they provide it is almost as if they were the ones that installed the system in the first place even though they weren't although i wish they had because we definitely would not be having the issues we are having had these guys been in charge during the installation."

"I called CZ Plumbing on Wednesday night and they were able to come out first thing on Friday. Zack was great and finished the job within 20 minutes or so. He also pointed out a few things whoever installed the water heater missed."

"We had purchased a water softener unit months ago, but no plumber would ever return our calls to install it. When we reached out to Nick, he immediately said he could do it. Nick is very knowledgeable, reliable and personable; and takes great pride in his work. He informs you of every step and will give you options for what can be done. I will continue to hire this young man whenever we need plumbing work."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
