A review of Chronomite water heaters for point-of-use and whole-house water heating, including the main features and specs of tank-type and tankless.
If you need a wall-mount and small tank-type unit with the capacity of a few gallons only and for jobs like dishwashing or handwashing, Chronomite is the brand you want to consider.
Also, the Chronomite company offers models with a continuous supply of hot water and reduced cold water flow, covering single and multiple applications.
Chronomite is a US company with a long history. The company designs and manufactures small and compact tank-type and tankless electric water heaters for residential and commercial applications for over 50 years.
Four tankless and one tank-type electric model are available for potable water heating. Due to the instantaneous heating and absence of the storage tank, tankless has many advantages, such as the high energy efficiency of 99%, on-demand water heating, continuous and endless supply of hot water, small and compact size.
Tankless electric models with a heating power of up to 10 kW are used mainly for point-of-use service, while those with the capacity from 10 kW to 154 kW can be used for whole-house water heating in homes and commercial applications as well.
It is worth mentioning that tankless models for home use come with a small, compact, and lightweight design, which allows easy and fast installation, and with on-demand heating water is always fresh, which significantly reduces the risk of Legionella bacteria development.
Chronomite water heaters that utilize a small water storage tank are designed for point-of-use applications only, where a small amount of hot water is needed for hand washing, small dish loads, and alike.
The tank-type models come from the CMT series and are available in three sizes, where the 4-gal unit, CMT-4, is the largest. These can be installed independently, usually under the sink, supplying mainly one fixture or in-line, connecting a large cylinder with the fixture, resulting in shorter delivery time, energy, and water savings.
The tank-type models are the simplest type and do not require any electrical work, saving you time and money during the installation. Tank-type water heaters come with the standard 110 V plug-in cord, so no need to call an electrician to wire the heater.
The CMT water heater can provide hot water with a temperature ranging from 50 F to 140 F, controlled by simply using the adjustable thermostat knob.
The advantages are small and compact size, energy and water savings, ease to handle, install, and affordable price. The disadvantage is the lower capacity making it unsuitable for use in whole-house applications.
All Chronomite water heaters with tankless technology heat water on demand, delivering in an endless supply. Those models that are used in residential homes come in the power range from 1.4 - 10 kW and are mainly designed for point-of-use service, while the largest models are used in the commercial industry, such as hotels, restaurants, schools, and large homes, and can provide power of up to 154 kW.
These can also be used in homes, as the large capacity makes them great for multiple fixtures and high-demanding applications.
Chronomite tankless water heaters for homes are found in the following series:
All of the Chronomite water heaters, except the SR tankless series and CMT mini-tank models, are equipped with the Digital Microprocessor technology, which allows controlled output temperature to avoid scalding temperatures while eliminating the need for a mixing valve.
The digital microprocessor allows very fast response time in temperature control to achieve stable temperature, less waste, and high energy efficiency.
According to the Chronomite manufacturer, when comparing the energy usage of the Instant-Flow SR models and Instant-Flow Micro models (3600 W model), savings are up to 45% in the summertime.
The Field Adjustable water temperature setting is found in the mini tank and two tankless models - Instant-Temp and High Capacity Instant-Temp.
The self-cleaning feature eliminates the risk of mineral deposits and drops in efficiency, reducing maintenance and service costs.
All the Chronomite water heaters are small, compact, easy to handle and install. Buying is also not a problem as they are affordable and have low installation costs, either done by a handy homeowner or a pro.
Chronomite SR models are basic models designed as instant electric tankless water heaters for point-of-use services, such as showers, lavatories, sinks in bathrooms and kitchens, and can also be used in some commercial applications.
Chronomite SR models come in several sizes and are grouped as the low flow (activation rate is 0.35 GPM) and standard flow models (activation rate is 0.65 GPM).
The low-flow SR models have a maximum power of close to 6,000 Watts and delivery rate up to 1 GPM. These operate in the range from 120 V to 277 V and use from 15 A to 30 A.
The standard flow models can produce more power - approximately 10,000 Watts and deliver more hot water - up to 1.5 GPM. They operate in the voltage range from 208 to 277 V and amperage of up to 40 A.
There are three Instant-Flow Micro categories: CM series, M series, and M-MM series. The great advantage of the Instant-Flow Micro models, compared to the basic Chronomite CR models, is the built-in digital microprocessor technology which reduces the effect of temperature fluctuation, high scalding temperature, and the need for mixing valves, while providing higher energy efficiency of up to 50%.
Chronomite Instant-Flow Micro models from the CM series come in several designs, operating in voltages from 120 V to 277 V and with the maximum power of close to 6,000 Watts, for the maximum water temperature of 160 F. In warmer regions, the largest models can provide up to 1 GPM, while most models up to 0.5 GPM in colder areas. Built as the low flow activation models, these can operate with the minimum water flow of 0.2 gallons, while most of the units from Chronomite are at 0.35 gallons and higher.
Instant-Flow Micro models from the M series are also found as the low flow models with the minimum operating flow rate of 0.35 GPM and power up to 9600 Watts, and standard water flow models with the minimum 0.65 GPM activation rate, and models with up to 11 kW of power. Both models can deliver up to 2 GPM of hot water, especially in regions with a mild-warm climate.
Instant-Flow Micro models from the M-MM series have similar specs as the above models but include the mixing valve for the applications where a steady temperature is needed. These also come with low and standard flow.
According to the manufacturer, the Instant-Temp series or E series is "top of the line" with an external digital temperature selection and a remote control option.
It is available as the low and standard flow models and can also serve as a booster. Low flow models, with the maximum power of 9,000 Watts, can provide up to 1.25 GPM of hot water.
Chronomite Twins & Triplets are the largest residential water heaters with a tankless design. The largest models come with a power of close to 29 kW and a flow rate of up to 4.25 GPM, making it great for use not only in point-of-use but whole-house applications. While these models are equipped with durable stainless steel casing, other models have it as an option.
The recommended Chronomite water heaters from the Twins category for use in homes are known as L2 models, available in two sizes (60 and 80 A), generating the power of up to 19,200 Watts and up to 3 GPM.
Chronomite Triplets or L3 models also come in two sizes with total Amps of 90 and 120, maximum power of 28,800 Watts and water flow of 4.25 GPM, making it great for high-demanding applications.
The Chronomite company has been building electric and tankless water heaters since 1966 and today offers a variety of small and compact models for residential and commercial use.
Either you need a tank-type unit with the capacity of 1 gallon or a powerful tankless model for your restaurant, retail store, or a large building; fixtures with a single and two handles, or automatic sensor faucets, Chronomite has it.
So, remember, the following features are what make the Chronomite water heater a good choice:
