The 10 Best 40 Gallon Hot Water Heaters

The heat electric tank less water heater S-16 model has the capacity of heating 3.5 gpm which is the equivalent to 2 showers (at 1.5 gpm each), and 1 sinks (at 0.50 gpm each) simultaneously, or any combination which equals to 3.5 gpm. The S-16 can handle these applications in the warmer climates of the us which are Florida, Georgia, Louisiana, Texas, Arizona, California, Alabama, and Mississippi. Anything north of these States the S-16 model can be used for point of use, or 1- application at a time. A good rule of thumb is if you live in the southern States mentioned here the S-16 can power a 3 to 4 bedroom 2-1/2 bathroom home, including dishwasher and clothes washer, please keep in mind that tank less water heaters are designed to heat incoming water at a maximum output temperature based on simultaneous use and inlet water temperatures. So if your demand for hot water decreases your output water temperatures will increase, as well as if you live in the colder States this S-16 will heat less volume of water, this will cause the S-16 to be used in point of use applications in the colder climates.

This compact , yet powerful unit – with gas inputs up to 140,000 BTU per hour – can meet all the hot-water needs of a small to medium American home or apartment. Designed to virtually do anything a 40-gallon tank-type water heater can do and much more The Wall mounted Excel Pro is design to work with hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. LCD Display Control: Just set the desired water temperature The Excel Pro has an energy factor of 0.84-0.85. Excel Pro: Modulating Technology Tankless water heaters can be further divided into two categories according to their heating capability: “full on/full off” versus “modulating”. Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies. Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit. The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.

Compact, space-saving design requires no venting and can be installed anywhere inside your home or garage. Unit is IP54 certified to keep internal components safe and dry. Durable and corrosion resistant stainless steel interior assembly allow for heating efficiency and longer life expectancy. Perfect for moderate to warm climates, the 24Kw/240V, 4.6 gpm capacity is ideal for small to medium sized homes that will be running up to 4 applications at once, such as: 2 Showers (1.5 gpm/shower head), 1 kitchen sink (1 gpm), and 1 bathroom sink (.5 gpm) at inlet temperatures of 73 degrees F. Colder climates that require a higher temperature rise will reduce the amount of applications and GPM (gallons pers minute). Choosing the right tankless heater depends on your incoming water temperature, flow rate, number of applications and your desired output temperature. Your incoming water temperature (also called inlet temperature) varies by location and seasonality. Colder inlet water temps require a much higher temperature rise.
