The Rinnai PN-721 Anti Frost Heater is a replacement part you can trust, specifically designed to fit Rinnai N Series external continuous flow water heaters. This heater is a critical component of the unit's built-in anti-frost system, and its job is to keep crucial internal bits from turning into ice in really cold weather.
These Rinnai N Series water heaters are pretty clever - they've got a built-in system that kicks in the heating elements when the temperature plummets so the internal pipework and components don't freeze up. That means even in the really harsh winter conditions the external units will still work like a dream.
But what if the PN-721 Anti Frost Heater decides to pack up on you? The water heater's a gonner then, and you're left with a repair bill that's more than you bargained for. Fortunately, a proper replacement from Rinnai sorts that out - you'll have your frost protection back up and running in no time and know that your water heater will keep on trucking all year round.
This PN-721 Anti Frost Heater is made to Rinnai's own specs, so you can bet it'll fit like a glove and work as it's meant to in those N Series external systems.
Keep your Rinnai water heater safe from that nasty frost with a genuine PN-721 Anti Frost Heater. Get one delivered to your door and know it'll keep working even in the coldest weather.
