Whether you live in a warm or cold region, having a water heater in your household is important.  There are actually many uses for hot water in a household; you can use it for the laundry, dishwasher, or when taking a shower.  This makes it very important to choose a good storage tank water heater whether if it’s for a new home or just replacing the old one.  However, relying on the sales pitch of sales agents does not necessarily mean you will be able to get a good one.  It is important that you equip yourself with some facts and knowledge about water heaters before going out to get one.  The list below shows some of the things to consider when choosing a good storage tank water heater.

  • Space – This is among the first things that should be considered when choosing a storage tank water heater.  This is mostly because storage tank water heaters cover a fairly good amount of space, say a square meter.  If your home has plenty of space to spare both outside or inside, then this shouldn’t pose as any problem.  Most storage tank water heaters are placed on basements, garage, or utility room.  However, if your home hardly has any space to spare, then you are better off choosing an electric tankless water heater.
  • Size – Size is also important when choosing a storage tank water heater.  This is mostly because you need to consider the amount of hot water the whole household will need.  Since the storage tanks usually vary in how much volume of water they can store, you need to be able to choose one that would be able to cater to the overall requirement of your household.  A 30 to 40 gallon tank is usually sufficient enough for 2 to 3 persons.  If there are 5 people in a household, it is recommended to have a 50 to 80 gallon tank.
  • Recovery Rate – This is a very important factor to consider in a water heater as this involves how much volume of water a water heater unit can heat in a span of 1 hour.  This means if you require a large amount of heated water per day, you will require a unit with a high recovery rate.
  • Operating Cost – Different types of tanks, heating element or system, and brand will usually have varying efficiencies which in turn yields to operating cost.  It is important to choose the type that fits your heating requirement, whether it is electric, propane, or natural gas.
  • Price – This is usually the aspect that wary most buyers.  The truth is everyone wants to have the best type of water heater.  The only problem is that the prices of the best types of water heaters are sometimes too steep for many.  This is the reason why some buyers are led into buying the cheaper ones.  Although there is nothing wrong with the cheaper types of storage tank water heaters as they are able to serve their intended purpose – to provide heated water.  Their only downside is that they are more expensive to run in terms of operating cost as compared to the more expensive types of water heaters.

When attempting to buy a storage tank water heater, it is important to consider the factors mentioned above so you will not have a hard time isolating the unit that suits you perfectly.  Never allow the sales agent to lure you into their sales pitch.  Try to do your research first before buying one.


Simple Tips on Water Heater Replacement

Having a water heater in your household can be very convenient.  However, when the water heater is old or breaks down and need replacement, it can be quite a problem.  The problem when replacing a water heater usually involves plumbing, which, most often than not, requires you to hire a professional to do the job.  Doing this yourself without any knowledge of the possible dangers can potentially make you do more harm than good.  On the other hand, if you are confident about your DIY skills, then you can do this task fairly easy, considering the tank you will be replacing is an electric type unit.

Before purchasing a unit, it is important that you consider the size of the new unit you will be buying and whether the space allocated for the old unit will be able to accommodate the size of the new unit.  Once you have your new unit ready, you need to do the following:

  1. Drain the Tank – Turn the circuit breaker of the unit off and turn off main water valve.  Open the taps in your home that are connected to the heater to empty the tank.  Once that is done, connect a garden hose at the drain valve and place the other end of the hose outside your house.  Open the drain valve to fully empty the tank.
  2. Disconnect the Electrical Wirings – There is a junction box at the top of the unit where there are two electrical wires.  Disconnect both of them by unscrewing their connection (be sure that the unit is turned off).  Mark them so you know where to place them back.
  3. Disconnect the Plumbing Lines – Make sure you know where the location of the incoming water and the outgoing hot water is.  If you are using a galvanized pipe, simply unscrew the union using a wrench.  However, if you are using a copper solid pipe, you need to have a hacksaw to cut through the copper pipe.  Make sure to cut below the shutoff valve and to cut straight.  Once you are done, file off the burrs and sharp edges and prepare for soldering.
  4. Remove the Old Water Heater Unit
  5. Position the New Water Heater Unit
  6. Reconnect the Water Line – If you are using a solid copper pipe for the outgoing hot water, solder the pipe and its fittings to the heater.  Reconnect the water main to the heater.  Use flexible copper pipes to make connecting easier.  Turn on the main water valve and check for leaks.  Be sure a tap is open so that air does not get trapped inside the tank.
  7. Reconnect the Electrical Wirings – Open the junction box and reconnect the two wires using the clamp or screws built in the unit’s connector.  Tighten the screws.

Before turning on your new water heater unit, it is important to set the unit the thermostat first to your desired temperature.  Having 120°F or 50°C is usually the recommended thermostat settings.  Once you have set the thermostat temperature, turn on the circuit breaker and enjoy.
