"Matt answered my request for work on my Hotwater heater very quickly. He quoted me an estimate on when he could come by my house to check it out, he was at my house at exact time! Looked over job and said he would get job completed right then. He completed job in very reasonable time. He did an excellent job. I would recommend Matt to anyone needing quality plumbing needs"

"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

One of the primary benefits of a heat pump water heater is how cost-effective it is. How much you save will depend on your water usage and electricity costs. That being said, we can ballpark savings for the average home of between $100 and $500 per year. You can increase that savings rate by researching and applying available energy incentives available in your area. If you really want to focus on cost, consider a tankless water heater.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.
