The immersion heater should not be left permanently switched on asthis will drastically reduce the contribution of heat pump to hot water heating and hence increase the running costs If the use of the immersion heater is necessary to meet the hot water requirements of a dwelling then the preferred method of controlling it is described below Control By Programmer The operation of the boost immersion heater can be controlled by means of an independent time switch as shown schematically in figure 13 The on time settings on the immersion heater should be between 30 60 minutes later than the on times set for the hot water programmer channel For example if the hot water is programmed to come on between say 0600 0900 and 1700 2200 then the immersion heater timer setting should be 0640 0900 and 1740 2200 This will make maximum use of the heat pump allowing itto charge the store to the maximum potential temperature before any use of the immersion element Additional top and bottom thermostat pockets are provided in case a more sophisticated control system is required to be fitted L Immersion heater Complete with control 230 ac 50Hz Immersion heater M o e suppl Pply E 4 amp overheat thermostats e 2 Pole fused Isolator 164 Immersion heater Time switch Figure 13 Typical schematic wiring diagram for the boost immersion heater using programmable immersion heater timer P

GN General All Torrent HP models covered by this manual are only suitable for open vented primary heat pump and space heating circuits Therefore the pressure in the primary circuit depends upon the height of the feed and expansion cistern and could be as low as 0 20 bar Therefore ensure that the heat pump selected will operate at primary circuit pressures e g it is not fitted with a non adjustable low system pressure switch The heat pumps normally operate at lower temperature difference 5 10 C between flow and return than that for a gas boilers 10 20 C resulting in higher flow rates in the heat pump primary circuit Therefore it is important that the primary pipework connecting the heat pump to the thermal store and the circulating pump are sized to achieve flow rates recommended by the heat pump manufacturer The efficiency i e coefficient of performance COP of a heat pump depends upon the primary flow and return temperatures and it is generally higher at lower primary circuit temperatures Also the heat pumps normally operate at lower flow temperatures typically 45 55 C compared with 75 80 C for gas boilers Therefore if traditional radiators are used then these should be oversized in accordance with the heat pump manufacturers recommendations For optimum operational efficiency and hence lower running costs a low temperature space heating e g under floor heating system should be used where feasible Heat Pump Sizin
