## Overview

The AQUAH Premium Direct Vent Natural Gas Tankless Water Heater offers a compact, wall-mounted design delivering 3.7 GPM with a powerful 28,000 Watt output and over 88% thermal efficiency. Its advanced thermistor technology maintains consistent water temperature automatically, making it an energy-efficient, hassle-free solution for modern indoor installations.

## Description

This is one of the most technically advanced units on the market, direct vent and thermistor regulated. Free stainless steel coaxial vent Pipe, ideal for indoor use for whole house, mobile homes, etc. The heating chamber of the water heater is sealed air-tight. Air for combustion is completely drawn into the heating chamber from outside and, at the same time, waste gases are 100% blown to the outside through the direct vent system. There is no pollution or consumption of air in the house and, therefore, no space requirements for combustion, making this water heater one of the safest to use. It is equipped with anti-freezing device to prevent the water heater from freeze damage by lighting up the burner and heating up the heat exchanger when temperature in the environment falls below 42* F (patented technology). Overheating prevention device shuts off the water heater to prevent overheating caused by overly high water temperature or by dry burning when water flow is too low. Flame failure detection device instantly shuts down the gas valve when flame is unexpectedly out. Water pressure releasing valve/water drain plug relieves water pressure when it exceeds the allowable limit in order to prevent water heater from being damaged; free 1/2" BSP (Metric) to 1/2" NPT adapters for gas/water fittings ($45 value).

## Customer Reviews

### ⭐⭐⭐⭐ Just got the heater and so far I'm pleased, but I can't vouch yet for durability
*by K***I on November 9, 2015*

Just got the heater and so far I'm pleased, but I can't vouch yet for durability. Only reason I'm giving it 4 stars rather than 5 is the instruction manual isn't very good. I found manuals for other Aquah heaters online that were much more detailed. Shipping was fast, the heater arrived 48 hours after I ordered it and customer service actually answers their phone. A couple of things to keep in mind, be sure to flush your water line before making the last connection to the heater because it if gets at all clogged with debris, it won't start. Also be prepared for a longer wait for hot water at the faucet then you'd get with a tank heater, but once the hot water arrives, it's nice and hot and stays at a steady temp. Given the amount of fuel I expect to save by no longer having to keep a tank heated 24 hours a day, I can live with waiting a bit longer for the water to turn hot at the faucet.
