I Own A Hair Salon, My Electric Hot Water Heater Runs Out Of Hot Water Very Quickly In The Winter, Yet In The Summer The Hot Water Seems Endless. What Could Be Causing The Problem?
Your options for water heaters are 29 gallons, 30 gallons, 40 gallons, 50 gallons, 75 gallons, 80 gallons, 100 gallons.
Make sure your thermostat is turned on High. For gas water heater, when turning up view to see if there is an increase in the fire that lights up.
Upgrade to a larger size WH. But if your tank is already large (75 gal - 100 gal) then purchase a smaller size (30 gal - 50 gal) and have it daisey-chained in conjunction to your current water heater.
From my own experience, I suggest that you go tankless. In my opinion, a tankless water heater will totally meet your needs.
