The lower the desired DHW tnk temperture, the more cost effective. By selecting lrger DHW tnk, you cn lower the desired DHW tnk temperture. The het pump itself cn produce domestic hot wter of mximum 55 C (50 C if outdoor temperture is low). The electricl resistnce integrted in the het pump cn higher this temperture. However, this consumes more energy. Dikin recommends to set the desired DHW tnk temperture below 55 C to void using the electricl resistnce. The higher the outdoor temperture, the better the performnce of the het pump. Determining the DHW consumption Answer the following questions nd clculte the DHW consumption (equivlent hot wter volume t 40 C) using the typicl wter volumes: Question Typicl wter volume How mny showers re needed shower = 0 min x 0 l/min = per dy? 00 l How mny bths re needed per bth = 50 l dy? How much wter is needed t the sink = min x 5l/min = 0l kitchen sink per dy? Are there ny other domestic hot wter needs? Exmple: If the DHW consumption of fmily (4 persons) per dy is s follows: showers bth sink volumes Then the DHW consumption = (x00 l) + (x50 l) + (x0 l) = 480 l Determining the volume nd desired temperture for the DHW tnk Formul V = V + V x (T - 40) / (40 - T ) V = V x (40 - T )/ (T -T ) Exmple If: V = 80 l T = 54 C T = 5 C Then V = 80 l If: V = 480 l T = 54 C T = 5 C Then V = 07 l V : DHW consumption (equivlent hot wter volume t 40 C) V : Required DHW tnk volume if only heted once T : DHW tnk temperture T : Cold wter temperture Setup nd configurtion DHW tnk For lrge DHW consumptions, you cn het up the DHW tnk severl times during the dy.

When chnging the defult pre-pressure of the expnsion vessel ( br) is required, tke following guidelines into ccount: Only use dry nitrogen to set the expnsion vessel pre-pressure. Inpproprite setting of the expnsion vessel pre-pressure will led to mlfunction of the system. Chnging the pre-pressure of the expnsion vessel should be done by relesing or incresing nitrogen pressure through the schräder vlve of the expnsion vessel. b Schräder vlve 6..5 To check the wter volume: Exmples Exmple The indoor unit is instlled 5 m below the highest point in the wter circuit. The totl wter volume in the wter circuit is 00 l. No ctions or djustments re required. Exmple The indoor unit is instlled t the highest point in the wter circuit. The totl wter volume in the wter circuit is 50 l. Actions: Becuse the totl wter volume (50 l) is more thn the defult wter volume (80 l), the pre-pressure must be decresed. The required pre-pressure is: Pg = (0.+(H/0)) br = (0.+(0/0)) br=0. br. The corresponding mximum wter volume t 0. br is 40 l. (See the grph in the chpter bove).
