Any new home built in the Mississauga area will have a thermostatic mixing valve above the water heater, regardless if your hot water tank is gas or electric. Mixing valves became code years ago for 2 main reasons; to prevent scalding and to prevent disease.
Scalds and burns from hot water used to be quite common. Young children and the elderly being the most at risk because of their young, tender skin and because of a slower reaction time. Both can further cause harm as falling becomes much easier when one make a sudden move in a slippery area like a tub or shower. A mixing valve prevents the hot water sitting in the tank from burning you. So why not keep the water in your tank at a lower temperature and solve this problem without putting a mixing valve on?
Illness is the reason. Mainly, a nasty disease called Legionella, which can grow exponentially in water set below 60 degrees. If you set the temperature of the hot water tank too low, you run the high risk of getting ill from water borne pathogens – Legionella is only one of many. But water above 60 degrees celsius does burn, so a mixing valve, installed above your hot water tank by the good people at John the Plumber Mississauga, is the best thing you can do, if you do not already have on in your home.
Mixing valves do exactly what the say they do; they mix hot and cold water so the water coming out of your tub, shower or sink will not burn you the moment you turn the hot water on. Simple and effective, but unfortunately they are not the strongest valves and they do need replacing as their lifespan is below the lifespan of a hot water tank. As a side note – many hot water tank rental companies do not repair or replace mixing valves – often that is up to the homeowner.
If you have ever burned yourself in the shower or washing your hands, you will know the value of this little gem – and if you find that your home is not getting proper hot water, quite often the mixing valve is the culprit.
