    No one ever uses hot water 24 hours a day. But, if you have a conventional tank then you’re paying to heat water 24 hours a day. With a standard water heater, you heat and reheat the same water even when you’re sleeping. No one wants to waste money but if you have a conventional tank that’s what your doing.

    The Rinnai tankless R85 water heater is a more efficient way to heat water for residential users. This system heats water quickly and delivers an endless supply of hot water for as long as you need it. With the Rinnai tankless water heater, you only pay to heat water when you need it and for as long as you want it. Thus Saving money.
