"Aleman Plumbing contacted me right away for an appointment to look at my water heater. Their quote was advantageous compared the the other I received and they were able to schedule the work immediately. My water heater was in a difficult location and I also needed to replace a pressure control valve but Carlos got it all done very well and was great to work with."

"The plumber can over the same day and examined what needed to be done. Installation of a leak detector. A quote was generated and it was approved. The plumber arrived on time Sat morning and had everything ready to go. Well organized. Work was completed on time and we only had to have the water off for 2 hours. Not cheap but reasonable/competitive and they show up and get it done."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

Water Heaters FAQs, answered by experts

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.
