Frequently Asked Quantity

Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be "essentially lead free" (less than 0.25% weighted average). For further information about how the law determines what is "lead free", rules regarding which plumbing products must be "lead free", and who these laws will affect, please view our page.

Q. "Will an instantaneous water heater save me money on my utility bills?"
A. In many applications you can see a savings. There are some variables that could reduce the amount you save. One example is you will not run out of hot water, so longer showers could cut into your savings. Also, the cost of electricity, propane and natural gas in your area will affect the amount of money saved. The higher the cost for the energy type used to heat your water, the quicker you can recover the higher initial cost of installing a tankless versus tank style water heater.

  • You will never run out of hot water. "You want an hour long shower? No problem!"
  • Electric units can be installed at the point of use.
  • You're not paying energy costs to heat water 24 hours a day.
  • Our electric units don't require a T&P valve (no tank!) - if code allows.
  • Installing a tankless water heater can indeed be a bonus to the environment. (Why choose wastefulness when we're talking about finite natural resources?)
  • They all need a minimum flow rate & pressure to turn on.
  • Electric units need heavy gauge wire, while gas units need a much larger, special flue pipe and larger gas supply than a conventional water heater.
  • At times they can produce very hot water. It's easier to get scalded - but this is easily mitigated with anti-scald valves.
  • With some brands, parts are hard to find (not a negative if you originally purchase from us, as we like to carry parts for the units that we sell).
Tankless water heaters have their place. They're not "the answer" to every hot water need, but if they're used correctly they can be the solution to many of them.
