It is a straightforward procedure to replace a pre-existing hot & cold domestic water system with a Lycris-Byrne glass-lined steel hot water storage cylinder featuring a fully-automatic, stainless steel, silent pressuring pump.
The system eliminates the need for electric power showers and the system can be expanded at a later stage (another bathroom) without any further changes to the pump or cylinder, as both hot and cold water are permanently pressurised.
The changeover, from a flow to a pressurised flow, can be achieved in less than a day. These cylinders can be used in place of the traditional copper hot water cylinder, using standard B.S.P. connections.

The Lycris-Byrne Tank-in-Tank is a hot water cylinder inside a geothermal collector/buffer tank combining the two functions into a single storage unit.
The glass lined stell inner tank has an operating pressure of 6 bar.
The outer buffer tank has an operating pressure of 3 bar and may be connected to the heat sources listed below:-

An electric immersion heater may be installed into the inner tank which can be fed from electric mains, wind turbine or photovoltaic cell.
A separate 100 mm foam insulation jacket ensures minimum heat loss.
