Ideal HP is a range of unvented hot water storage cylinders, manufactured in the latest
high quality duplex stainless steel. They are designed to provide mains pressure hot
water and are supplied as a package which complies with Section G3 of the Building
Regulations. The appliance is extremely well insulated using high density HCFC free
foam insulation with an ozone depleting potential (ODP) of zero and a global warming
potential (GWP) of 2. It is fitted with all necessary safety devices and supplied with all
the necessary control devices to make installation on site as easy as possible.
Ideal Heat Pump (HP) and Slimline models:
The Ideal HP and Slimline cylinders unvented hot water storage cylinders fitted with
a high efficiency coil. The coil has a low pressure loss due to it being a multiple pass
coil which enable high flow rates to be achieved through it. In addition due to the
coil being corrugated the heat transfer rate is higher than that of plain tube coil.
The cylinder has been specifically designed for heat pump applications. It incorporates
an immersion heater at the base of the unit which enables pasteurisation of the water.
This should be done on a regular basis in line with HWA guidance..
The slimline has been designed to enable it to fit into tighter locations.
Important notes:
1. All Ideal HP models are suitable for both open vented and sealed primary systems.
2. When used with a sealed primary heating system, the heat pump must incorporate
its own over heat thermostat.
3. Ideal HP models must not be used with uncontrolled heat source or steam as the
heat source.
4. Heat pumps can normally only heat the domestic hot water to between 45 – 50°C,
therefore provision should be made to periodically heat the cylinder to above 60°C
to prevent growth of legionella.
5. The cold supply elbow c/w drain tapping must be fitted as shown in figures 1 &
2. A flexible hose can then be connected to the drain tapping and providing the
hose runs below the lowest level of the cylinder, then all the water content can
be drained out by the symphonic action.
