HELP TO IDENTIFY YOUR HOT WATER SYSTEM.
HIGH PRESSURE(HP): Recommended.
Water pressures of 1.0 bar and above are usually supplied from the following systems:
Combination (combi) boiler systems(HP): Recommended.
Cold water from the mains water supply is heated by the combination boiler.
Pressure range: 1.0 Bar to 5.0 Bar.
Average flow rate of Hot water: 10 Litres per minute.
Ideal for all IXIA/KYRA Bathroom Taps and Showers (excluding Kyra and Oslo body jets).
Unvented mains hot water cylinder(HP): Recommended.
Cold water from the mains water supply is fed to the hot water cylinder pressurising the hot water. e.g. Megaflo
Pressure range: incoming cold water mains supply usually set at 3 Bar on cylinder.
Average flow rate of hot water: 20 Litres per minute, depending on incoming mains cold water pressure and pipe sizing.
Ideal for IXIA/KYRA Bathroom Taps and Showers ( including Kyra and Oslo body jets).
Pumped tank feed gravity hot water systems(HP): Recommended.
Low pressure system converted to high pressure hot water system by the addition of a pump.
Pumping the Hot and Cold tank fed supplies to the Shower.
Pressure range: 1 Bar to 3 Bar Pumps Single or Twin Pumps are available.
Average flow rate: Depends on size of Pump, Distance to be pumped, Resistance in pipework, Size of pipes.
IXIA/KYRA Bathroom Taps and Showers work well with the sizes of Pumps above.
IXIA/KYRA Showers with Kyra and Oslo body jets require a 3 Bar pump on 22mm pipes to Shower with short and low resistance pipe runs.
Why choose a Thermostatic Shower for a Pumped System?
Answer: If the cold water storage tank is emptied quicker than is filled hot water will still be pumped to the Shower, all of our Thermostatic Showers Mixers feature ANTI SCALD PROTECTION and shut down when the cold water supply fails.
LOW PRESSURE GRAVITY: Not recommended.
Water pressures below 0.5 bar are usually tank feed gravity hot water systems. This is usually where a cold water storage tank is in the loft and displaces the hot water from the hot tank to your taps and shower.
The pressure (in bar) can be worked out by calculating the vertical distance between the bottom of the cold water storage tank and the shower head or tap.
E.g. Distance of 2 meters from bottom of Cold Water Storage Tank to shower head = 0.2 bar Low Pressure.
