What are the Different Types of Hot Water Heaters Available?

Among the two main water heater types, tank and tankless, there are many different options from which to choose. A team member from Plymouth Plumbing & Heating will be glad to discuss the pros and cons of each style with you, to help you select the best option for your family’s needs.

Conventional Storage Tank Water Heater
This traditional option features an insulated tank holding the water. The size of the tank determines how much water can be heated at once. Conventional water heater types are the most affordable and easy to install.

Tankless (On Demand) Water Heater
A tankless water heater uses super-heated coils that fill with and heat water as you need it instead of keeping a tank filled with hot water all the time. Water gets heated quickly and is available as needed, on-demand, which is a good option for large families. Tankless water heaters work best with natural gas and are extremely energy-efficient; they are considered green plumbing.

Heat Pump (Hybrid Water Heater)
These water heater types use up to 60% less electricity because they use the heat from surrounding air to heat water. Therefore, they do not work well in cold spaces like basements. The pump is located on top of the tank, which requires up to eight feet of space overhead.

Solar Powered Water Heater
These models draw their energy from the sun and are the most energy-efficient of all water heater types available. They require the installation of solar panels mounted on your roof or property. While Solar Powered Water Heaters are environmentally friendly, they are quite expensive.

Condensing Water Heater
These water heater types use unused natural gas fumes in your home to heat your water. They are very energy-efficient and are for homes that run on natural gas. They require a larger tank, but are a good option for large families or homes that require a hot water capacity over 55 gallons.

What Does a Hot Water Heater Installation Cost?

Water heater installation costs will depend on the type and size of water heater you choose, as well as any other work that is necessary, such as adding new piping or electrical wiring. Switching from a tank to a tankless water heater will also require additional work and costs. The necessary work permits and any plumbing fixtures that must be brought up to code will also factor into your final water heater replacement cost.

Tankless heaters will have more upfront costs than tank heaters, but they are energy-efficient and eco-friendly, saving you money in the long run. Also, gas heaters are less expensive than electric heaters. Call our professionals today to get your water heater installed, replaced, or repaired!

What Causes a Hot Water Heater to Wear Out?

Hot water is very corrosive over time, and can wear down your hot water heater and its components. Moreover, if you have hard water, or water that contains a high amount of minerals, this can cause rust and sediment buildup over time.

If your family uses a large amount of hot water, you may have a water heater that is too small for your usage level, and it can wear out quicker than the average lifespan. A good-quality water heater should last 8-12 years on average.

What Do I Do When My Hot Water Heater Breaks?

First, turn off the water to the water heater and shut off the power to the unit. Then, remove any furniture or salvageable items from water-damaged areas. Clean the areas soaked with water. Run a dehumidifier to prevent mold growth. Call the trained professionals at Plymouth Plumbing & Heating to evaluate, repair, or replace your old water heater.

You should also prepare to file an insurance claim. Do not throw out your damaged water heater, as your adjuster will need it to assess the damage while calculating your insurance payout.

Had a new boiler system installed on the last week of December '22. So far, the system is noticeably more efficient with having to run less with more radiant heat produced.Gary and his Apprentice worked a long day getting this system installed but not once faltered in their professionalism and knowledge of my unique heating system.I've had numerous jobs done by Plymouth Plumbing & Heating over the course of 11 years in my home. New sink, garbage disposal, faucet and of course working my my old boiler system multiple times.Prices are fair, given the state of the economy and one certainly gets their moneys worth!I highly recommend Plymouth Plumbing & Heating.

Plymouth Plumbing and Heating installed a water heater for us. The work was completed in an efficient, professional manner and the area was left neat and clean. The owner, Zack, is really involved and easy to work with. We will definitely use them again in the future if the need arises.

Plymouth Plumbing & Heating are absolutely amazing! Our sub pump went out & had flooding. They showed up promptly to help. Zack was very friendly, knowledgeable and gave us a solution so that we would not run into this problem again. His technicians are efficient & very friendly as well. I will never go to anyone else again! Thank you PP&H!

These guys are a dream. I wish all contractors worked like them. They've done a few well pump projects for us and most recently ran the connection from a new deep well to our water pump, which required coordination with a well driller and concrete subcontractors.They bent over backwards to coordinate with the others on the project to make sure costs didn't blow up and the project was done as quickly as possible. They were awesome about reaching to tell me where things stood with the project before I'd even call for an update. They know their craft and do an excellent job explaining the problem, the possible solutions, and answering questions from people like me who don't generally know anything about plumbing.Huge thanks to Zack (owner) and Gary for always exceeding our expectations. Don't bother calling anyone else - these are the guys you want.

We recently had PPH do a major update in our home (water heater, water softener, iron filter, reverse osmosis, new hose bib & installed a toilet). Zack was very knowledgeable and was able to address our very hard iron rich well water. After updating 30 year old mechanicals, our water is iron free and drinkable. I cannot recommend these folks enough. They are prompt, professional and stand behind their work. Look no further, this is your next plumber.

We called because our drains were backed up and we were not able to use water in the house at all or we had water coming up from the main drain. They showed up quickly and had it all done and taken care of in under an hour! The owner is also a super helpful guy and he came out and got our water heater working for us early in the morning when no one else was available!

I rarely write a service review but feel compelled. Friday afternoon around 1 I called because my water heater was out. By 4:30 Logan had found and retrieved the last water heater in stock in the area ( after much searching ) AND installed it! Friendly, efficient, professional, and SO HELPFUL! Thank you.
