Patriot was established by four industry leaders with over 50 years of collective experience. Drawing from extensive collaboration with major home improvement corporations, we developed a strategic vision that culminated in the formation of Patriot. Our motivation stemmed from identifying inefficiencies within prominent home improvement firms and their impact on everyday consumers. At Patriot, our mission is rooted in a commitment to serve the community.

"Although I am pleased with the completed shower, I did not have a great experience. Mason was the sales man, and he was lovely except during the sales process he showed me doors that they no longer stock. No big deal except the doors that we agreed on were not what was delivered. Jim the project manager came out and measured the enclosure , then ordered what we had agreed and put a deposit on. We were told it may take 10 weeks to come in?. It did.

Water Heaters questions, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

The time it takes to replace a water heater depends on the complexity of the job. Expect your contractor to spend:

  • One to three hours on a standard tank-style water heater replacement

  • Two to three hours on a tankless water heater replacement

  • Four to six hours replacing a tank-style water heater with a tankless water heater

  • One hour for each additional parallel or point-of-use water heater

Your project will take longer if you’re switching fuel sources, upgrading to tankless, or relocating your water heater.

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.
