There are many things that you should keep in mind when you are designing your bathroom. One of the most essential things that you should have in your bathroom is hot water on demand. This is a very important feature. No one likes to take bath in cold water in the early winter mornings. It is a nightmare to use cold water when you live somewhere that is so cold that you would be freezing your body off while taking bath. Some are even discouraged to take bath because of the unavailability of a tankless hot water heater. Therefore you should make sure that you have the facility of hot water on demand in your bathroom so that you can carry out all your morning ablutions in the bathroom.
There are many ways that you can obtain the hot water on demand. One of the easiest ways is to get a electric or gas tankless water heater. This will help you to make sure that you have the right kind of water heater for your needs. You can heat your flowing water at any time of the day and use it for whatever needs that you may have with the hot water. There are plenty of uses of the hot water on demand.
You can use it to take bath or for beauty treatment or to warm yourself up if you are too cold. Also you can use it for medical emergencies as in situations of frostbite where hot water is absolutely essential. At times like these if you do not have hot water on demand then you would be in a world of trouble. You should make sure that when you are moving into a house, one of the most essential facilities that they have is a reliable hot water heater so that you can be comfortable.
If you have never owned a hot water on demand unit you might be wondering: are tankless water heaters any good? What are the pros and cons? What should I look for if buying one?
Tankless water heaters have a couple of advantages – they don’t use energy to keep water hot all day, and they don’t take up much space. An electric point-of-use water heater costs about what a regular water heater does and can be installed under a sink if power is available – they’re a little larger than a hardback book.
Whole-house tankless water heaters are larger than the point-of-use heaters and more expensive than tank-type heaters. Gas heaters have to be vented, and the electric ones have hefty power requirements. Some plumbers and plumbing supply stores sell tankless water heaters.
The key to being happy with a tankless water heater is sizing it properly – it must heat enough water hot enough to please the family member that takes the hottest showers. To size a tankless water heater , you have to know how much you need to raise the temperature of a certain amount of water – which is easy to calculate. Have that hot-shower lover adjust the shower water to the desired temperature then measure it. Today’s low flow showerheads use 2 1/2 gallons or less per minute – federal law. Older heads can use up to 7 gallons per minute. If you aren’t sure of the gallons per minute, then shoot the water into a bucket for a minute and see how many gallons you have.
Let us say you like the shower water to be 110 degrees Fahrenheit (a hot shower – average shower temp is 104). The coldest water I’ve ever measured going into a water heater was in the 40 to 50 degrees range. It follows; on the coldest mornings, for that 110-degree shower, you would need the heater to raise the temperature of at least 2 gallons of water by 60 or 70 degrees per minute. Knowing that, you can pick the heater that will do the job.
One of the problems with tankless electric water heaters is the amount of power they need. For instance, the heater needed to produce a 110-degree shower on a cold winter day would require almost 100 amps. Right now my home requires fewer than 100 amps for everything including our new deluxe electric knife sharpener.
An alternative would be to combine a tankless with the existing water heater. Then we would just have to boost the temperature of the not-hot-enough water from the conventional water heater going to the new bath. Just boosting the temperature 30 degrees cuts the power requirements in half.
