Price factors:

  1. Type of unit - There are two "types" of tankless water heaters: whole-home and point-of-use. Whole-home units heat up water for all plumbing appliances in your home whereas point-of-use units heat water for one specific appliance. Whole-home units are more expensive than point-of-use units. But, if you have a large home or household, you may need a whole-home unit AND one or more point-of-use units, which will increase the cost of your installation.
  2. Flow Rate - Flow rate is the number of gallons of water a tankless water heater can heat in 1 minute. The higher the flow rate, the more expensive the tankless water heater will be.
  3. Fuel Type - Gas water heaters cost more upfront than electric ones do, but gas is usually a cheaper form of fuel than electricity is, so you'll likely see lower water heater costs with a gas water heater.

Tips for longevity

How to prolong the life of your tankless water heater

Tankless water heaters are a hefty upfront investment, so we're willing to bet you want yours to last as long as possible. Below, we've compiled a few simple ways to extend the life of your tankless water heater as long as possible:

  1. Invest in regular maintenance- At least once a year, you should hire a professional to maintain your tankless water heater. Like most homes in Pittsburgh, you probably have hard water. Over time, hard water can result in mineral build-up in your water heater, which can cause other issues. Having a professional regularly maintain your water heater will help prevent any long-term damage.
  2. Buy extended warranties- If your water heater does need a repair, the cost may be covered under your warranty, which will allow you to extend the life of your current system rather than having to replace it altogether.
  3. Invest in the right set up- If you have a larger home or household, it's important that you invest in the right amount of point-of-use units in addition to a whole-home unit. This way, your tankless water heaters will be able to meet the hot water demand of your home and won't be overworked.

We know, it's a lot to remember, but luckily for you, Calfo can help with all 3 of these tips. During the installation process, we can help you determine which water heater set up and warranties will work best for your long-term needs and budget. And, we offer a thorough tankless water heater maintenance check-up, so you can rest easy knowing your tankless water heater is getting the care it needs to last as long as possible.

We would recommend this company to anyone
"We had a water heater installed.... the company was able to respond to us on the same day that we made the initial phone call and they followed up with an email that contained confirmation of a visit and also a picture and information on the individuals who would be entering our home. The initial salesperson was extremely polite and explain things to our satisfaction. The follow-up visit was made by the installation technician... who was also professional and polite.... and install the water heater and then explained warranties. We would recommend this company to anyone who is in need of a water heater replacement."
