Question:
I’ve heard tankless heaters sometimes “cold water sandwich” you mid-shower. Does the Fogatti FG38FR do that?
asked by: Megan
Expert Reply:
Megan, older tankless heaters were known for that, but Fogatti improved the design. The Fogatti 55k btu tankless water heater with 18" by 18" black door # FG38FR uses a microprocessor to regulate flame output and stabilize temps when flow changes, so you don’t get icy blasts when the pump cycles or another faucet opens. The # FG58FR is the same inside, but has a white exterior service door if that matches your RV better than black.
Do you usually camp with kids opening faucets mid-shower, or is it just you trying to keep the water steady?
