Quick answers
Is 2.5 GPM enough for my RV?
It suits lighter hot-water demand; incoming water temperature and shower flow affect the result.
Can it replace a 10- or 12-gallon tank heater?
The 18 × 18-inch door option supports many larger former tank openings; match it to the actual cutout and
trim coverage.
Does it include freeze protection?
Yes, but the RV plumbing still needs proper winterization when temperatures fall below freezing.
Complete your RV setup
For compact trailers and smaller Class B/C layouts, start with right-sized 13.5K cooling and 25K ducted heat.
13.5K rooftop cooling is the right-sized companion for smaller RV interiors. Confirm the roof opening and select the matching ducted or non-ducted ADB.
Choose AC configuration25K output and 220 CFM airflow suit smaller furnace replacements. Confirm cabinet orientation, ducts, exhaust, propane and 12V power.

Right-sized hot water for compact RVs
InstaShower 7 delivers 48,000 BTU and up to 2.5 GPM. It is designed for compact travel trailers, smaller Class B/C layouts, couples and warm-weather users who normally run one hot-water fixture at a time.
End tank recovery waits without oversizing
For a smaller RV and lighter household, the entry model can replace a limited tank without oversizing the hot-water system.
Keep showering while utilities remain available
The shower is no longer limited to a stored six-gallon volume or a 20–30 minute tank recovery cycle.
Match 48K output to lighter demand
The 2.5 GPM platform is right-sized for couples, compact trailers and one primary hot-water fixture at a time.
Cover the old exterior opening cleanly
15 × 15, 15 × 18 and 18 × 18 options support many Suburban, Atwood, Dometic, Girard and Furrion replacement layouts.
Retain core travel and safety features
The heater keeps the system simple while retaining the safety and control features expected for travel.
Right-sized continuous hot water for compact RV travel
Its 2.5 GPM platform suits couples, compact rigs and one primary fixture at a time.
The lower-flow platform aligns with smaller interiors and one-fixture use.
It replaces tank recovery limits with an efficient flow platform for lighter daily demand.
Warmer incoming water reduces the temperature rise the burner must deliver.
Match the door to the old opening
The 13 × 13-inch minimum opening pairs with 15×15, 15×18 or 18×18 exterior-door coverage.

Reviews
"Never delivered stuck in Tennessee now for almost 1 week and two days still waiting"
I received the unit
"I received the unit a few days after ordering it. This unit is replacing an existing tankless water heater in my Scamp 13. I plan on doing some high altitude camping and wanted a WH that was rated for it. I installed it yesterday. Vary easy to install. Basically just switched them out as the one I replaced has the same dimensions and hook ups. Fired it up this morning and it worked like a charm! I haven't tested it camping yet, but I don't foresee any problems. It's a well made product that's reasonably priced!"

"This is very well made quality product. Instant hot water on demand. I would recommend it to anyone looking to replace their standard water heater."
I have zero complaints
"I have zero complaints about this water heater. Fairly easy to install and works like a charm. Taking a 30 minute shower and never losing hot water was absolutely amazing. Now, I ordered this product on amazon first and it showed up late and damaged. I returned it and ordered it directly from the fogatti website. Was late again but was in good condition. That's on FedEx. Other than the shipping problems this water heater is amazing. As long as you have propane you have hot water and I absolutely love it."
