Learn More About Chronomite Instant-Temp® Tankless Electric Water Heaters
Looking for a water heater that can help prevent scalding? These Chronomite tankless electric water heaters feature a "digital microprocessor" that controls the outlet water temperature by monitoring the temperature of the water over 100 times per second to provide an immediate response to any changes in incoming water temperature, pressure and flow rate as they occur. Digital monitoring assures the outlet temperature does not exceed your selected temperature.
This is the top of the line Chronomite model and the outlet temperature can be adjusted at any time by the press of a button if the "digital remote" is purchased separately. If you decide not to purchase the digital remote, then you simply choose a factory preset temperature, 104°F, 110°F or 120°F (please specify here).
NOTE: The microprocessor adjusts the heater's power for variations in flow rates and pressure to assure the selected factory preset water temperature. The microprocessor limits temperature rise according to the factory set temperature.
The compact size, 10-3/4"(w) x 7-5/6"(h) x 2-3/4"(d), along with 1/4" female NPT inlet and outlets, and the fact that a temperature and pressure relief valve is not needed (unless required by your local codes), gives you versatility and lower installation cost than a small tank type heater can offer you.
98% Energy efficiency can save you money by not wasting energy because the water being used heats instantly as it flows through the water heater. All Chronomite units comply with Federal Safe Drinking Water Act standards and meet ADA requirements. They can be used for many purposes with great results in public lavatories, private lavatories, kitchen/bar sinks, service sinks, scrub sinks, showers, dishwashers, multiple lavatories, rinse down sinks, emergency eye wash stations, and other special applications. If you have hands-free or sensor faucets then the Instant-Temp® with the 104°F factory preset temperature works without the need of a mixing valve.
The Instant-Temp® Low Flow models have a minimum working pressure of 45 psi. (lower pressure models with a minimum 25 psi are available). The maximum working pressure is 150 psi. The water heater flow switch activates at 0.35 gpm and deactivates at .30 gpm. The manufacturer recommendeds the maximum flow rate to be 0.5 gpm unless used in multiple lavatory situations which then the maximum recommended flow rate would be 1 gpm for 2 sinks and 1.5 gpm for 3 sinks. Failure to install the provided .5 gpm faucet flow control will cause unsatisfactory operation.
The Instant-Temp® Standard Flow models have a minimum working pressure of 45 psi. (lower pressure models with a minimum 25 psi are available) The water heater flow switch activates at 1.0 gpm and deactivates at .65 gpm and the manufacturer recommended maximum flow rate is 1.5 gpm for optimum performance. These Standard Flow models are not recommended for multiple lavatory situations. Failure to install the provided 1.0 gpm faucet flow control will cause unsatisfactory operation.
LOW PRESSURE? Order low pressure models that operate with a minimum of 25 psi

Frequently Asked Questions
Q. "I ordered one of these water heater units and chose a factory preset temperature of 104 degrees. Now that I've received my unit, I realized that I want it to set at 110 degrees. Is that possible?"
A. Yes, these Instant-Temp® water heater units feature a potentiometer allowing you to adjust/change the factory preset temperature. If you order a digital remote, you can easily change the temperature setting.
Q. "Your products specify the 'temp. rise' based on the GPM flow; what do you mean by this?"
A. Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water. If you don't know what your incoming water temperature is, we offer a chart that shows average groundwater temperatures in the USA, or you can check with your local water district for the actual temperature in your area. Please note this can be adjusted by any sort of preheating (such as solar heaters).
Q. "How much do I need to raise my incoming ground water temperature for ____________"
A. This is a highly personal question as everyone's opinion is different. Combine that with the differences in incoming water temperatures and you have a different answer for each installation. However, a lot of studies have been done on what people (on average) find comfortable, so we can give you some very general numbers to help you narrow the possibilities. These studies have shown that most people are comfortable washing their hands at near body temperature and find showers comfortable at 95°F to 105°F, depending on whether they prefer cool or hot showers. Nearly everyone agrees that 57°F is too chilly for comfortable hand washing, much less showering.
Q. "Will an instantaneous water heater save me money on my utility bills?"
A. In many applications you can see a savings. There are some variables that could reduce the amount you save. One example is you will not run out of hot water, so longer showers could cut into your savings. Also, the cost of electricity, propane and natural gas in your area will affect the amount of money saved. The higher the cost for the energy type used to heat your water, the quicker you can recover the higher initial cost of installing a tankless versus tank style water heater.
Positives:
- You will never run out of hot water. "You want an hour long shower? No problem!"
- Electric units can be installed at the point of use.
- You're not paying energy costs to heat water 24 hours a day.
- Our electric units don't require a T&P valve (no tank!) - if code allows.
- Installing a tankless water heater can indeed be a bonus to the environment. (Why choose wastefulness when we're talking about finite natural resources?)
Negatives:
- They all need a minimum flow rate & pressure to turn on.
- Electric units need heavy gauge wire, while gas units need a much larger, special flue pipe and larger gas supply than a conventional water heater.
- At times they can produce very hot water. It's easier to get scalded - but this is easily mitigated with anti-scald valves.
- With some brands, parts are hard to find (not a negative if you originally purchase from us, as we like to carry parts for the units that we sell).
Summary:
Tankless water heaters have their place. They're not "the answer" to every hot water need, but if they're used correctly they can be the solution to many of them.
Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be "essentially lead free" (less than 0.25% weighted average). For further information about how the law determines what is "lead free", rules regarding which plumbing products must be "lead free", and who these laws will affect, please view our page.
