There are many reasons to go tankless when choosing your next hot water heater. They can replace an existing insulated tank system or complement an existing hot water supply source. Best of all, they can also supply a limitless amount of hot water on demand.
Why should you replace your old tank with a tankless water heater?
When your old hot water tank either stops heating water or rusts out and leaks its contents all over your floor, or both, you should consider the additional initial expense of switching to a tankless unit.
Tankless water heaters save money by heating water on demand, rather than storing it and using energy to keep it heated in an insulated tank.
Tanks can only hold a limited amount of hot water, so when the hot water runs out, one or more family members must either take a cold shower or wait until water is heated inside the tank.
New insulated tanks must meet federal efficiency requirements, which include additional external insulation. This may cause a new tank to be too large for the space allotted for the old tank. If the new tank doesn't fit in the existing space, plumbing will need to be rerouted to a larger space to accommodate the new larger tank.
Tankless water heaters are small enough to be hung on a wall in the space where a tank has been removed.
Tankless water heaters as a complement to existing units
Tankless water heaters don't need to meet all of the hot water supply needs of a home. Smaller units can be installed in areas such as bathrooms for extra shower capacity for larger families, while the rest of the home can be supplied by an existing insulated tank system.
Tankless water heaters are also a perfect complement for solar hot water systems, which can be inconsistent and dependent on the amount of available sunshine in relation to daily needs.
Their capacity to heat water on demand allows environmentally-responsible homeowners to use solar power for as much of their needs as possible while still saving energy by using fossil fuels only to heat water, not to keep it heated in a storage tank.
The thought of endless hot showers, without the accompanying guilt of subjecting other family members to lukewarm showers at best as with traditional tank systems, easily overshadows all of the above mentioned practical considerations and justifies any additional expenses for converting to a tankless unit.
