McNabb’s Guide to Water Heater Selection
Your Premier Pittsburgh Plumber helps you choose the perfect water heater for your Pittsburgh home. The Department of Energy reports homes using tankless systems save up to 34% on energy with daily usage under 41 gallons.
Tank vs Tankless – The McNabb Difference
Traditional tanks store hot water ready for your family’s needs. Tankless systems heat water on demand, giving you endless hot water. Gas tankless units deliver 5 gallons per minute, while electric models provide 2 gallons per minute.
What sets each type apart:
-
- Tank sizes from 20-80 gallons fit any family size
- Space-saving tankless units mount on your wall
- Tankless units serve your family up to 20 years, tanks 8-10 years
Energy Savings You Can Trust
Look for the Uniform Energy Factor (UEF) rating. Higher numbers mean lower bills. Large gas tanks (over 55 gallons) need 0.86 UEF or better. Gas tankless systems must reach 0.95 UEF.
Right Size for Your Home
Our 40 years of Pittsburgh plumbing experience guides your tank size choice:
- 30-40 gallons serves 1-2 people
- 40-50 gallons works for 3 people
- 50-75 gallons fits 4-person homes
Tankless sizing matches your peak needs. Most showers use 2.5 gallons per minute, dishwashers 1.0-3.0 gallons per minute.
