VITOCELL 300-H Indirect-fired domestic hot water storage tank 42 to 119 USG / 160 to 450 ltr Technical Data Manual Model Nos. and pricing: see Price List Product may not be exactly as shown Vitocell 300-H EHA Series Horizontal indirect-fired domestic hot water storage tank of high-grade stainless steel 5167 534 - 01 03/2014 Product Information Vitocell 300-H Fully hygienic, efficient and economical domestic hot water production with DHW tanks of high-grade stainless steel – horizontal version. The benefits at a glance: H Corrosion-resistant tank of high-grade SA 240-316 Ti stainless steel offers a long service life. H Fully hygienic due to high quality homogeneous stainless steel surfaces. H The high-alloy material is immune to cracking or peeling. The tank stays hygienic and requires only minimum service. H The entire water content is heated by a 1¼” / 32 mm diameter stainless steel heat exchanger surface which extends to the bottom of the tank. H The stainless steel heat exchanger coil is self-venting towards the top and self-draining towards the bottom, therefore not susceptible to reduced heat transfer due to air lock or sediment deposits. H Standby losses minimized by 2¼” / 58 mm highly effective, foamed-in-place HCFC-free insulation. H Easy transport into mechanical room due to low weight and compact construction. 5167 534 - 01 H Certified to CSA Low Lead Content Certification Program; including US Safe Drinking Water Act, NSF/ANSI 372 as well as other applicable US State requirements. H The positioning of the tubular heat exchanger coil further ensures that 82 to 97% of the tank volume can be drawn at constant water temperature. 2 VITOCELL 300-H Product Information Cross-Section 2¼” / 58 mm thick foamed-in-place HCFC-free insulation Inspection port/ clean-out opening Non-finned, stainless steel, tubular heat exchanger coil extends to tank bottom – the entire water volume is heated ensuring no cold spots where bacteria growth could occur 5167 534 - 01 Tank is constructed of high-grade SA 240-316 Ti stainless steel Product may not be exactly as illustrated.

Installation of additional aquastat(s) 5167 534 - 01 WARNING In a multiple tank installation, it is recommended that an additional high limit aquastat be installed in the common domestic hot water supply header to the system. This aquastat should be wired in series to the operating aquastat on the tank battery. The setting on this additional high limit aquastat should be approximately 9°F / 5°C higher than the operating high limit. VITOCELL 300-H Ensure that temperature tempering valve(s) is/are installed if the domestic hot water storage tank temperature exceeds 140°F / 60°C to protect from scalding. Consult plumbing codes and authorities for local requirements. 7 Vitocell 300-H in a Multiple Tank Installation Product Delivery Domestic hot water draw rate Quick recovery (over 10-minute period) Max. domestic hot water draw rate (over 10-minute period) Storage tank content heated to 140°F / 60°C, boiler not reheating Domestic hot water rise from 50 to 113°F / 10 to 45°C Domestic hot water rise from 50 to 113°F / 10 to 45°C Storage capacity USG ltr 92 350 119 450 Battery storage USG capacity ltr Number of tanks 184 700 2 240 360 900 1350 2 3 DHW draw rate GPM ltr/min 7.9 30 Domestic hot USG water draw ltr Water with t = 140°F / 60°C (constant) 166 630 Percentage of battery volume 7.9 30 119 450 7.9 30 232 349 880 1320 Storage capacity USG ltr 92 350 119 450 Battery storage USG capacity ltr Number of tanks 184 700 2 240 360 900 1350 2 3 Heating water supply temperature 194°F / 90°C 176°F / 80°C 90% 97% 97% 158°F / 70°C USG/10 min ltr/10 min USG/10 min ltr/10 min USG/10 min ltr/10 min 119 450 Quick DHW recovery (over 10-minute period) 219 317 433 830 1200 1640 219 300 408 830 1137 1545 203 277 378 769 1050 1430 Storage capacity USG ltr 92 350 119 450 Battery storage capacity Number of tanks USG ltr 184 700 2 240 360 900 1350 2 3 Heating water supply temperature 194°F / 90°C 176°F / 80°C 158°F / 70°C GPM ltr/min GPM ltr/min GPM ltr/min 119 450 Max.

The well diameter is large enough to accommodate a wide variety of sensing bulbs. Ø 1”/24 mm 15”/380 mm Ø ½”/15 mm Ø ¾”/19.2 mm 7”/175 mm Ø ¼”/7 mm Ø 1/3”/ 9 mm The sensor well is welded into the DHW tank. Heating water supply temperatures over 230°F / 110°C Temperature and pressure relief valve For these operating conditions, an approved high limit safety aquastat must be installed to limit the domestic hot water temperature to 203°F / 95°C in the tank. A temperature and pressure relief valve (T&P relief valve) is supplied with the tank. The heating contractor must install the valve on each tank in a method meeting code requirements. If local codes require a different relief valve, substitute the manufacturer’s supplied valve. The tank is approved for 100 psig where a CRN is required. Maximum operating pressure is 150 psig. Vitocell-H domestic hot water tank positioned under the boiler Please note that only the boiler/tank combinations stated in the Price List are possible. In the case of the 92 USG / 350 ltr capacity Vitocell 300-H , the boiler can only be positioned on the DHW tank so that it is flush at the front. The T&P relief valve supplied with the tank is ASME pressure steam rated for 998 MBH and CSA temperature steam rated for 200 MBH. It is tested under ANSI Z21.22 code for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems. Recirculation tapping The recirculation tapping on the Vitocell-H 300 is also the opening for mounting the temperature and pressure relief valve. If this opening is utilized for recirculation, extend the stainless steel nipple on the tank with a brass tee of the same size as the stainless steel nipple ∅ to accommodate both connections; see installation instructions. 10 For steam applications, a field supplied 1” T&P valve must be utilized. Watts Model 40XL-8 100 psig 150 psig (Canada (US and where Canada) CRN is required) Always use spring clip to ensure proper contact of capillary bulb against the stainless steel well for proper sensing/heat transfer! Warranty excerpt Our warranty for domestic hot water tanks states that the water heated should be of drinking water quality and that any water treatment equipment in use must function correctly. If the product has been improperly installed or misapplied by the installer, contractor or final user, Viessmann accepts no responsibility for damage howsoever caused and reserves the right to withdraw the product warranty. In order to qualify for product warranty, strict adherence to the installation and service manuals must be observed. In the event that Viessmann non-approved components are utilized, Viessmann reserves the right to withdraw all expressed or implied warranties without written notice. The water to be heated with the Vitocell must be drinking (potable) water quality. If the tank is used to heat other media, the warranty will be null and void. Damage resulting from excessive pressure or temperature is clearly not the responsibility of Viessmann. The amount of chloride and sulfate acceptable to the tank is limited. In areas where high concentrations of chloride and sulfate are present in drinking water, please consult Viessmann for directions. ASME pressure steam rating 998 MBH 1438 MBH CSA temperature steam rating 205 MBH Relief temperature 210ºF (99ºC) For full warranty details, please read the product warranty card. Inlet thread ¾” male Backflow preventers Outlet thread ¾” female Where backflow preventers are required, a domestic water expansion tank installation is recommended in the cold water inlet piping before the cold water enters the Vitocell. For the backflow device, observe local plumbing codes and regulations.

Enter chart at left and draw horizontal line across to recovery rate of 284 GPH / 4.7 GPM for 140°F / 60°C domestic hot water under column A. Where the horizontal line intersects the 194°F / 90°C curve is the point of intersection for the diagonal line used to size the pump. The diagonal line begins at the origin and goes through the point of intersection extending up to the top of the chart. Read between the reference diagonal lines to get a pump specification of 15 GPM at 4.5 ft. To summarize: For a Vitocell-H 300 with 119 USG / 450 ltr capacity and 238 MBH input, the boiler water temperature is 194°F / 90°C, difference between boiler return and supply water temperature is 31°F / 17°C, recovery rate is 4.7 GPM of 140°F / 60°C DHW, and the pump required is 15 GPM, 4.5 ft. plus pressure drop in piping and boiler. If a multiple tank application is required, i.e. 4 tanks at 238 MBH input each, then the pump selection would be (4 x 15 GPM) 60 GPM at 4.5 ft. plus piping pressure drop.
