Would highly recommend to anyone! The Technician showed up on time. Went directly to work servicing the system. He kept us well informed about his progress and notified us of any issues that he discovered, along with any options. He made the process as easy and pleasant as possible.
They were able to come out and fix the issue all within a few hours. The technician was friendly, explained what had happened, and was quick to fix the toilet! I will be calling Preferred Home Services from now on for my household plumbing needs! We had a fantastic experience with Preferred Home Services! Mike and Nick took care of some plumbing needs we had and were so knowledgeable and professional.
The customer service throughout our whole experience has been second to none! Very happy with Preferred Home Services. They were very professional and courteous during the installations. They were very efficient and took time to explain everything to me before and after, and very prompt with follow-up questions. At 6 PM on a degree day, I noticed that my system was not cooling and was in fact down.
I called and was pleased to have someone pick up the phone and listen to the symptoms of the problem. They ultimately dispatched a repair person who was able to get the system up and running by PM in advance of a long, hot holiday weekend, I was very pleased with the prompt response to my emergency. They installed a new unit and replaced all the duct work under my house.
They did a great job and were very professional and had the job done in just two days! I will highly recommend this company to anyone needing work. This business is incredible. Called for service due to our HVAC not working at all. It was late afternoon and a Technician was at our door within the hour Love preferred home services.
They are responsive, knowledgeable, and have great customer service. I've used them at both properties for HVAC issues. I love that the text a picture of who is coming, along with a bio. Gang showers, when supplied with a single temperature-controlled water supply pipe, shall be controlled by a mixing valve that conforms to ASSE The water heater thermostat shall not be considered a suitable control for meeting this provision.
The codes generally agree if there is a hazardous condition or a condition that is unsafe or a nuisance to life, health and property it should be corrected. It is also generally agreed that water above degrees Fahrenheit at fixtures for bathing and washing with a few exceptions for lower temperatures can be considered dangerous and proper precautions should be taken to prevent the hot water from being a scalding hazard by using the proper safety devices.
When I hear about people setting their water heater to degrees Fahrenheit to prevent scalding, I know they have good intentions, but most people do not know you cannot accurately control the hot water temperature leaving a water heater with the thermostat dial.
If you adjust the water heater thermostat for the burner or heating element on a water heater down to degrees, it will not prevent scalding. Water heater thermostats cannot be relied upon to control the hot water temperature leaving a water heater.
Water heater manufacturers recommend that installers set thermostats at - F, and most of them ship the water heaters at an even lower temperature setting. It is not possible to set a water heater thermostat at a given temperature and get a relatively constant temperature of hot water from a water heater. The thermostat can not accurately control the water heater outlet temperature with a water heater thermostat.
My experience has been that not many people know that water heater thermostats cannot control the outlet temperature of a water heater. This warrants an explanation of how a water heater thermostat works so everyone understands the dial on the water heater does not have the accuracy to control the outlet temperature of storage type heater.
Water heater thermostats do not provide precise temperature controls for hot water systems. I have talked to water heater manufacturers that have indicated that the controls can vary as much as 15 to 18 degrees Fahrenheit above or below the set point of the thermostat.
From my experience, I have recorded the temperature leaving the top portion of a water heater over a long period of time during intermittent uses and saw temperature swings over 40 degrees Fahrenheit leaving the water heater. The shower valve standards do not have this kind of temperature fluctuation included their testing for all types of shower valves.
The significant temperature swings are because the thermostat is inserted into the lower portion of a water heater tank and turns the fuel supply to the heater on and off. Most new water heater thermostat dials have no way to know what the temperature in the tank is.
Generally, if the water heater thermostat dial is set at degrees Fahrenheit, the burner would come on when the temperature at the thermostat reaches about degrees Fahrenheit. The burner stays on until the water around the thermostat which is near the bottom of the heater reaches about degrees Fahrenheit. This provision in the standard accounts for the phenomenon known as "stacking" or "thermal layering". The hot water is less dense and rises to the top of the hot water tank.
Just like hot air rises and lifts a hot air balloon, hot water rises to the top of the tank and the cooler water drops to the bottom of the tank. Stacking or thermal layering occurs when the hot water rises to the top of the heater due to recurring short duration heating cycles caused by a frequent number of small quantity hot water uses. Frequent short draws cause cold water to enter the bottom of the water heater where the thermostatic element senses the cold water from the turbulent flow stirring in the bottom of the heater.
The cold water causes the water heater to cycle on. This phenomenon can occur in any type of storage water heater and generally is more significant in vertical heaters. I have recorded temperatures as high as to degrees Fahrenheit at the top of water heaters that had the thermostats set between to degrees Fahrenheit.
Temperatures over degrees Fahrenheit are extremely high temperatures and can cause serious scald burns in only a two seconds of contact with the skin. See Table 1 - Water Temperature Effects on Adult Skin It should be noted that the time temperature relationships in Table 1 are based upon the thickness of the skin for adult males.
How should you set your temperature with so much riding on it? There is no set or straightforward answer, and some of it does indeed come down to personal preference. However, here are a few tips you can follow to make sure your temperature setting is perfect for you.
Some homes will need it quite a bit hotter for reasons we will discuss momentarily, but be careful when going beyond this benchmark. For young babies, it takes just two seconds of exposure to water at degrees Fahrenheit to cause third-degree burns, and just five seconds at degrees. Bringing the temperature down is much, much safer for your baby and better for your energy costs too. If you have an infant or any child under the age of three, we recommend a water heater set at no higher than degrees.
However, those who suffer from suppressed immune systems or who deal with respiratory diseases may want a hotter water temperature to both kill off bacteria and create a higher concentration of steam in the air when showering.
For these populations, provided there are no younger children in the house, we recommend a water temperature of no higher than degrees. Pre-heating dishwashers are becoming popular. These systems take in water and then boost the temperature to even higher levels for an even better and more sanitary clean, and they do so without requiring you to boost the temperature coming from your water heater.
