Grant Concept system with thermal storeAlternative use of energymanagement controlsThis layout shows a system incorporating aThermaWave thermal store, linking a numberof different technologies such as an oil boiler,2 air source heat pumps, a solar thermal system,a GES264 sequence controller and a GEO360weather compensator.Grant ThermaWave storesThe Grant ThermaWave allows multiple heatsources to be connected in a number of differentways. This unit makes it possible to now have agas or oil fired boiler connected to a solid fuelappliance and also a renewable heat sourcesuch as solar thermal or a heat pump. Underfloorheating system manifolds as well as radiatorcircuits can be directly connected to the storeand it has been designed in such a way that itslows inlet water velocities, ensuring multi-leveltemperature distribution.Models are available in three sizes - 250 litres,300 litres and 400 litre, in an open-ventedconfiguration.A separate domestic hot water kit (product code: GTHERM/KIT1)is also available for those situations where domestic hot watersupply is required. Alternatively, where there is a greater hotwater demand the store can be linked to a Grant cylinder(as shown below).System with thermal store incorporating anumber of heat sourcesTwin channelprogrammer10 wayjunction boxConcept drawing only- not site specific070e Outdoor sensorsited on north facing wallRoomsensorRoomstatHeating zoneReturnGEO-360eFlow070e Outdoor sensorsited on north facing wallMixer sensorCentral heating pumpGES264Boiler flow sensorReturnMixerpumpOpen ventFlow4-port mixingvalve & actuatorCylinderstat2-portvalveSolar hotwatercollectorFlowBoiler flow sensorThermal store thermostatGrant SolarcontrollerOilboilerNRVASHP 1NRVASHP 2NRVCF2-Port high temp zone valvewith unvented HW cylinderReturn10
