Tankless Water Heater For Shower
Tankless Water Heater?
How does a tankless water heater work? Can it be used for multiple items at the same time? (ie. laundry, dishwashing, 2 showers). Do you install one unit that heats water to every appliance in the house? How long do they generally last? What should I expect cost-wise?
They work on the principal of heating what you will use. When the unit calls for hot water, the burner lights and heats the water that go through coils, cold water in – hot water out.
If you have high water use (2 or more people) don’t install a tankless. The demand will never keep up. There is a common fallacy with tankless heaters being an endless supply. Sure you are only heating the water when you need it, but if you are doing laundry and washing dishes at the same time, it’s not for you and will cost more in the long run.
Cost wise, they are 2-3 time more than conventional tank heaters and cost more to install, especially if you get a plumber not familiar with a tankless. Additionally, you will find that most plumbers are not in agreement with the “endless” theory. Hope this helps.
