When turning on a hot water tap why does the water begin to warm up but then suddenly go cold before it begins to get hot again?
If you do not have a separate hot water heater, it is possible that you have a mixing valve on your boiler and if it is open, it creates an imbalance in the system. So while you are taking a shower and someone turns on the hot water in another area of the house, the pressure on the cold side increases an follows the direction of least resistance and mixes more cold water with the hot than it normally would. As a result, the water in your shower get colder. This can happen even if the mixing valve is completely closed. In the same way, if someone turns on the cold water somewhere else while you are taking a shower set just the way you like it, the water could all of a sudden become very hot. Mixing valves were the answer years ago to mix cold water with super hot water coming from the boiler. They never work very well. So, the best way to avoid temperature fluctuations is to replace faucet with built in temperature adjusting controls. Set the temperature you want and if the pressure, hot or cold drops, the faucet will automatically adjust and the temperature to your setting. Your water pipes might come in contact or are very close to a hot water heat pipe or a heating duct. It may be in the same joist bay. When you do not use the water for a while the water near the heat source stays warm. When you turn on the water the water will seem warm at first and as the water further downstream (which has cooled off) comes up, the cooler section flows through until the hot water in the water heater gets to your fixture
What is wrong when furnace running in the cycle of gas turning up then fan turning on then thermostat not displaying plus gas turning down then fan stopping then thermostat displaying again?
What does it mean if you and a guy are cool We were talking but ran into a few problems and after 4 weeks of not talking we're suddenly cool...What does that mean exactly?
Well, whatever reason made you UNcool, if you didnt talk about it, how will you deal with it in the future, not talk again and then be suddenly COOL, again. Fix the problems that were coming into the relationship and work on the emotional end of it. Dont you find it weird to just suddenly be COOL, again. I would want to get the crap out of the way and clear the air.
