Tankless water heating systems have grown to be more commonplace, since in the long run, they save you money. Boasting cheaper operating and energy costs, tankless water heating systems are more effective and are greener than hot water tanks of the conventional type.
Traditional Hot Water Tank vs. On Demand Water Heater
With advancements in technological innovation, you can get on demand hot water anytime you need it, as opposed to hanging around for a water tank or cylinder to warm up.
There are actually several benefits of tankless water heating over the old procedure.
• Heating Loss – Whenever water is preheated to be held in a tank, there’s a great deal of energy and heat losses. This will be avoided with on-demand hot water heaters.
• Life Expectency – Regular hot water heaters usually last ten to fifteen yrs as compared with the almost double 20+ years life duration of an on-demand water heater. Thus, you save on repair costs. This consideration also helps to cover the higher purchase and installation cost which comes with tankless water heating systems.
• Storage Tanks – By the use of tankless water heater solutions, you don’t require a storage tank. A regular water heater pre-heats and stores 25 – 50 gallons in its water tank which has to be warmed up continually. An on-demand water heater provides warm water whenever you need it, getting rid of large storage cylinders.
• Power Bills – A conventional hot water heater pre-heats and heats water to a preset temperature level irrespective of your actual hot water needs. This may lead to highly inflated electric bills. With an on-demand hot water system, your usage of energy is linked directly with your hot water requirement. There is no pre-heating involved. For this reason, your power bills will come down.

Hot Water Heater Choices
Did you know that your Water Heating is the second largest expense in your home accounting for 14% to 18% of your Utility Bill. I didn’t make that up. That’s according to the Department of Energy (DOE).
Most people are unaware of the choices you have in Hot Water Heaters (HWH). Most often you go by a recommendation from the local plumber or Big Box Store. In fact, how many of us actually think about what kind and size of a hot water heater we will have installed. Better yet, the energy source. Usually, the only time you think about it is when you walk down stairs to your basement to do a load of wash and there is water all over the floor. At then it’s damage control and how are we going to take showers!
A conservative estimate is the average household spends between $400.00 and $600.00 per year on hot water. Again, not my statistics (DOE), I tend to think it is more. The energy source has a lot to do with it, the number of people in the household and the amount of water being heated. Another fact is that approximately 27 million households have HWH’s over ten (10) years old.
With a little planning there are many choices.
Here are the most common.
a) Storage Tank Hot Water Heaters (HWH)
b) On Demand Tankless Type
c) Indirect Tankless Coil
d) Indirect Tank Type
e) Solar panels w/storage tank
f) Heat Pump
Most consumers are familiar with (a) storage tank HWH. Typical fuel source is Gas, Electric, Oil, Propane, Geothermal and Solar. Each one of these has pros and cons. A lot depends on your budget and where you live geographically. The most inefficient one of the bunch would be (c) Indirect Tankless Coil. These were most popular on the East Coast. The engineering is simple which I won’t go into. The theory behind it is that the Hot Water Boiler would be running seven months a year to heat your house so during that time one would not use considerably more BTU’s to heat the domestic hot water as well. This was okay when fuel oil was a buck ($1) a gallon!
Let’s stick with the most popular HWH (storage tank type “a”) and give you some tips on how to be Energy Efficient and practical as well. And do not forget periodic maintenance.
1) The most common energy source would be electric and natural gas. Natural Gas being more energy efficient and having a higher recovery rate.
2) Insulate the HWH with an insulating blanket. These can be purchased according to size. You can also use duct wrap or batt insulation and a lot of duct tape. This will help the standby loss. (the temperature drop of the water sitting in the tank idle)
3) Insulate the hot water piping minimum 10 feet from the HWH. If the heater is in an exposed basement insulate all the hot water piping.
4) Set the temperature of the HWH to 120 degrees.
5) Install low flow shower heads and faucets throughout.
6) Wash your clothes with cold water whenever possible.
7) Purchase Energy Star Appliances.
1) Check the pressure and temperature valve (T&PV) every six months. This is the safety valve to prevent the HWH from blowing apart. It should not be leaking, capped or be rusted. I advise having a plumber give it a once over until you are familiar with what to look for.
2) Check and replace the Anode Rods when needed. This keeps the HWH from corroding.
3) Flush a quart of water or so from the hot water tank every few months to remove any sediment.
Well, that’s the short course on hot water heaters. If your HWH is more than five years old plan ahead. It always pays to be prepared
