Water Heaters questions, answered by experts

No. Boilers and water heaters are not interchangeable because they serve different purposes. A water heater will never be able to supply warm water or steam for your central heating system. In most homes, a boiler and a water heater may be combined to provide heating and daily use of hot water. Other homes may opt for a furnace over a boiler for their heating needs.

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.

Standard electric water heaters (about 40 gallons) typically need a 30-amp circuit breaker. But if you have a newer model, a tankless water heater, or one that’s more energy efficient, you’ll likely need a higher amperage to power it. 

Having the right size circuit breaker for your water heater is an important part of making sure it heats water efficiently and runs safely. A licensed electrician can help you navigate your options, and determine what you need for your new water heater. 

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

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.
