Electric Instant/Tankless Water Heaters
Atmor Electric Instantaneous Water Heaters, designed according to Israelii standards, supply continuous hot water as needed. Unlike storage heaters, water is heated only upon use, totally removing standby heat loss, and translating to savings on your electric bill.
With fully automatic operation, multiple safety cut-offs, easy-to-maintain and replaceable heating element and engineered quality design, you can be sure your shower stays warm, safe and convenient.

General Features
Mechanical Design
Mechanical design means easier and more affordable repair and maintenance
Cleanable Heating Element
Hard water (common especially in Alabang and deep wells) leads to calcium deposits inside your water heater that reduce the efficiency of the heating element inside your water heater. You might notice the effects of hard water when you have to set your heater to Medium or High to get the same hot water as you originally get using only the Low setting. The calcium deposits reduces your heater's capacity to produce hot water and wastes a lot of electricity.
Among the instant heater brands sold in the Philippines, only Atmor has easily replaceable and cleanable heating elements. You can clean the heater tank and element by yourself or your repair person to make sure your heater is providing the best hot water for your electricity.
Replaceable Heating Element
When your water heater has a damaged heating element, you can opt to save yourself money by only replacing the heating element. Unlike in Atmor, most instant heaters, especially those with copper tanks, do not have replaceable heating element. This is because their heating elements are part of their tank assemblies. If you have a problem with your heating element, even though you might have a 5-year warranty on it, you might still have to pay to replace the whole tank assembly.

Multi-Point Features
Manual Resettable Thermostat
Manual thermostats are similar to the durable thermostats used in storage heaters. When the overload protection is activated, the manual thermostat can be reset from the inside of the heater to return the heater to normal operation. Automatic triac thermostat also provides the same functionality but may have very limited number of activation.
Magnetic Flow Switch
Atmor's magnetic flow switch has a lower activating pressure than the traditional pressure switch. This can be important in areas in which pressure is too low.
Automatic Pressure Relief Valve
The pressure relief valve required in all multipoint water heaters releases water when there's excessive buildup of pressure in your instant heater. The excessive pressure maybe due to non-use of pressure reducing devices in the design of your building or condominium. In most instant heaters in the market, the pressure relief valve is a one-time activation type. Once it is activated, the heater will continuously leak water. Without proper drainage, this can possibly cause huge incidental damages to your home.
Atmor pressure relief valves are resettable and are similar to those used by more durable storage heaters. When there's buildup of pressure, only enough pressure is released by the valve. This minimizes potential damages to property.

Bennington Instant Water Heaters are top-of-the-line heaters uncompromising in quality and safety features. Bennington heaters are made in Singapore and designed for strict Singaporean regulations. All Bennington heaters comply with the latest International Standard IEC 60335-2-35: 1997-12, Singapore Standard SS146:Part 2:5 1999 and IP 25 Splash Proof Standard.
What Safety and Quality means:
- Bennington heaters use large copper cylinder tanks certified to withstand pressure of 10 bars and tested up to 20 bars.
- Complying to the IP 25 Splash Proof standard minimizes the possibility of electrocution and damage to the heater circuitry.
- High quality dual Japan copper elements ensure both element durability and efficient performance in heating capacity.
- Safety is assured by German designed “Pressure Differential Flow Switch” (PDFS) and Dual Thermal Cut-Offs. The former prevents overheating or rupturing of the heating cylinder under extreme high pressure. The latter provides double thermal cut-off protection compared to the single thermal cut-off found in conventional instant electric water heaters.
