"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

Water Heaters questions, answered by experts

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.

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. 

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
