HOT & COLD PIPING SYSTEM

Prior to installation of storage water heater, the hot and cold piping system must be installed behind the tiles of the bathroom concealed for neat installation. Check below for the types of piping to use for the cold and hot piping system.

SWH-Mixed Tap System

MIXER TAP SYSTEM

The hot and cold piping system must be connected to the mixer tap system to mix the cold and hot water that produces the right temperature for use. Different types of mixer tap are available from thermostastic control to the twist and turn lever system.

2. Check ceiling space in your home.

SWH-Manhole Access

MANHOLE ACCESS

Manhole should be beside or nearby the unit to enable easy access for maintainance work. The size of the manhole should be around 1 1/2 feet or bigger for easy access to the unit.

SWH-Ceiling height

CEILING HEIGHT

Check the ceiling space on top plaster ceiling in order to install the tank on the concrete wall. Make sure there is ceiling allowance of 2 feet to position the storage water heater.

3. Check the water pressure by checking distance from water tank.

Water Pressure System
from Water Tank:

SWH-Water Tank

If water pressure is from the water tank and your home is 2-3 storeys high, generally you will need a water pump.

Water Pressure System with
Centralised Booster Pump:

SWH-Centralised Booster pump

Getting a Centralised Booster Pump will boost your water pressure at least 1 bar and storage water heater can supply hot water to your shower point.

4. Check the distance between bathrooms

SWH-Distance

SHARING UNIT FOR 2 BATHROOM

Less than 15 Feet Away

2 Bathroom ( Side by side )

Closer the unit to the point eliminates time taken for hot water to reach the point of use

Saves waiting time and reduces water wastage

SPLIT UNIT FOR 1 BATHROOM

More than 15 Feet Away

Individual Bathroom

Closer the unit to the point eliminates time taken for hot water to reach the point of use

Saves waiting time and reduces water wastage

What is JOVEN Heat Elevator™ (HE) Technology?

Heat Elevator (HE) technology is the world’s first innovation that uses patent pending magnetic device that accelerate the convective heat transfer and improve heat stratification in water. This magnetic device is uniquely designed to weaken the inter-molecular bonding energy and accelerate the movement of water molecules to improve heating efficiency.

  • Joven Heat Elevator has been widely recognized by leading certification bodies in Singapore
SWH-HE Technology

*Available for JSH Series With Heat Elevator (HE) Models only

SWH-HE Tecnology

How Does It Work?

The comparative photos shows the effect of HE which cause more heat loops than conventional storage water heater. The heated water is spread wider across the heater tank, thus ensuring less heat trapped at the heating element, therefore prolong the heating element life and generate more hot water in the tank.
