Other highlights include thermal balancing and blending valves and tempering valves, to … The choice is yours but bear in mind that your water supply is chlorinated and in a domestic application it is unlikely that legionella would be a problem if you do not have anybody in the house with a weak immune system. For combined heating hot water and domestic hot water systems, when the heating hot water system exceeds 140°F the IPC code requires a temperature actuated mixing valve conforming to ASSE 1017 to limit the domestic hot water temperature to a maximum of 140°F. If the temperature of the water in your cylinder isn’t hot enough, the bacteria that causes the disease, Legionella pneumophila, can grow and you may be at risk. The normal temperature of tap water depends on the ground temperatures and the building temperatures through which it travels to get to your tap. Through its elegant swan-neck, the tap delivers domestic hot, cold and filtered hot water up to a temperature of 98ºC. The temperature of stored hot water must be over 50 degrees for a few hours per day. To get hot water, a domestic hot water system needs to take the cold water up to around 50 degrees C. – I know there are also considerations to periodically take it above 60 degrees C to prevent the Legionella bacterium growing in the water system. If you’re worried about pathogens in your hot water, and are worried about scalding water, consider a hot water tank booster. But anything over 70° is wasting money in #gas and #electricity #energy #fuel bills, creates unnecessary #carbon and can cause painful scalding – particularly for children. If you can test the temperature at the tap and see if it really is 45 or if it is hotter hopefully the thermostat is faulty. In Nursing homes or where children are concerned 105°F (40.5°C) maximum is the preferred temperature. England and Wales, from 1 April 2010, revisions to Part G of the Building Regulations (Hot water supply and systems) include the requirement that baths, subject to building regulations, are fitted with a protective device (i.e. Because a hot water temperature over 46° (ideally 60+) should ensure legionella bacteria – the cause of Legionnaires’ Disease – do not survive,. However some people like to get there temperatures to about 67°, which is great if you like your water really hot, but isn’t much good for the plumbing system on the hot water. This keeps your water at 140 degrees in the tank but mixes it with cold water to lower the temp to 120 degrees before it reaches the tap. I am guessing it is about 65 degrees F. We have a well. 45 is warm. I was pondering the temperature of the cold water tap! It’s worth noting that the temperature of the tap water should always be lower than the radiator output temperature. The hottest water temperature bearable by the hand is 50C but this is not hot enough to kill the legionella bacterium. A- Depending on local code but normally a min of 100°F (38°C). The model plumbing codes do not address a maximum storage temperature. Within our temperature control range you will find an extensive selection of thermostatic mixing valves (TMV valves) suitable for both domestic and commercial heating and hot water applications.
