1 THE RAD YU CA TRUST 1 eneral uide The following guide illustrates how Wundafloor warm water underfloor heating systems can be coupled together with the majority of central heating plumbing and control systems. The majority of modern central heating systems make use of motorised valves, often called Zone valves, to divide different heating systems and hot water generation ie., Under Floor Heating and Hot water cylinder. Systems using combination boilers will also need zone valves if separate systems of heating require different times and temperatures. Quite often ground and first floors are controlled separately as they may have different uses. The zone valve acts like a relay, meaning any system can call the boiler/ heat source without other areas being activated. If the underfloor system is being encorporated alongside a radiator system it is even more important that these areas are controlled independently as heat up and cooling off times are different. We recommend the S plan layout is adopted as this allows for more variety in zoning, and should be very familiar to qualified plumber/ electricians. The schematics show typical S-plan heating systems with under floor heating encorporated. TE: An Auto y-pass valve (AV) should be incorporated in all systems. TE: If a Heat pump manifold has been supplied then there will be no pump on the manifold. Therefore the relay on the H-ox wiring centre is used to switch on a shunt pump which will send primary water from a buffer tank or the heatpump itself to the manifolds. Wundafloor does not supply: S plan wiring centre Cylinder thermostat Hot water time clock Auto bypass valve otorised / Zone valves and Pipe stats are available if requested.

9 THE RAD YU CA TRUST Section C 2C : Wiring schematic for single zone kit added to radiator system 230V 50Hz E Wundafloor Programmable Thermostat 1 A standard dial thermostat may be power from a time clock. This is when a single zone underfloor heating kit is connected to an existing radiator system without an individual zone valve for the UFH and therefore unable to call the boiler/heat source independently for heat. 9 Although a room thermostat or programmable thermostat can be used to control air temperature, this area can only be when the existing heating system is. Terminal lock When this is the case, a pipe thermostat can be attached to the heating mains flow, so that the new area of the underfloor knows when hot water is available and therefore stops the pump running when no heat is available.

The valve must be positioned on the return from the heated floor. It is recommended that isolation valves are used for filling and maintenance. The supply pipework must not be less than 15mm. The heating engineer must check that the is adquate flow available from the heating mains.
