Let’s talk Water Heaters…

Due to popular demand, we will be talking about water heaters today bringing you the latest reviews of everything water heater from our plumbers and gas engineers here at Baker Smith Ltd.

If you haven’t replaced your water heater in a few years or buying a brand new one this year, you’ll get more options and more energy-efficient regulations – so do your homework before buying one.

It’s often the case that spending a little more up front on a reliable and highly efficient model will save you more money in the long run.

Before deciding on a model you also have to consider the type of water supply that you have. If your home is supplied with hard water, you could find your water heater failing within the warranty period.

It’s always wise to consult a professional or a manufacturer to fully understand the new regulations before buying.

Water Heater Installation

Always have a registered plumber carry out your installation, whether you are replacing an old heater or installing a new one. At Baker Smith our professional team of plumbers can repair and install all types of water heaters.

Water Heater Considerations

Here is a guide that will help you buy the best water heater for your home.

Consider the capacity of the water heater:

Water Heaters mostly sold on the basis of how many gallons they hold. So, it is important to decide on how much storage capacity you need before buying a heater. For example, if a family of four people uses 100 gallons of hot water in an average day, it doesn’t mean that you need a 100-gallon storage tank in your water heater.

Consider the rating:

It’s important to consider the first-hour rating (FHR) for storage-tank heaters and gallons-per-minute rating (GPM) for tank less water heaters because that’s what tells you how much hot water the heater can deliver over a set of time, i.e the first hour.

Consider the size:

If you are replacing an old heater, don’t assume the new one will fit in the old one’s place. Due to improved insulation and other efficiency, some newer models may be wider and/or taller than your old water heater. It is always better to take a professional’s help.

Consider the type:

Decide on what type of water heater you want – Depending on how much hot water you use and how you’re heating the water (gas, oil, electricity), you have a lot of options. Some newer types claim to cut energy costs by up to half than that of your older, regular storage models.

Types of Water Heater:

There are different types of water heaters on the market today so it’s important to be aware of what types are available so that you can make the right choice for your home.

  • Tankless (On-Demand) Water Heater – As the name suggests, it doesn’t have a storage tank, rather uses heating coils for heating water on demand. These types of heaters are best for houses that use natural gas to heat water.
  • Storage Tank Water Heater – These are the most common types, comes with a temperature and pressure-relief valve, which opens if either of the pre-set level exceeds. Runs on both electricity and natural gas, but gas models cost more initially.
  • Heat Pump (Hybrid) Water Heater – This model heats water by capturing heat from air and transfers it to water. They don’t work well in colder places and needs 7 feet clearance from the floor to ceiling. Also, it needs up to 1000 cubic feet of uncooled space to capture enough heat and a nearby drain to discharge the condensate.
  • Condensing Water Heater – If you heat with gas and need a unit with more than 55 gallons capacity, this is what you need. It has a conventional water heater tank. However, it captures exhaust gases which normally go out of the flue, wasting energy.
  • Solar Water Heater – These are more attractive in warm sunny regions. A roof mounted set of solar sets absorbs heat and transfer it to antifreeze closed loop system that runs to the water tank. Although, even with federal and local discounts, you need to wait for 10-30 years to retrieve the buying and installing costs.

Water Heater Features:

The below mentioned features you should always consider before buying a water heater.

  • Warranty – Most heaters come with a typical 3-12 year warranty. Even if you have to pay more for a longer warranty, choose the models with the longest warranty for best value.
  • Brass vs Plastic Drain Pipes – Look for brass drain pipes as the are more durable than the plastic ones.
  • Glass-Lined Tanks – This feature helps to reduce corrosion.
  • Anti-Scale Devices – While scale can shorten the life of heating elements, don’t invest in fancy features. Rather look for a model that includes a longer or thicker heating element.
  • Digital Displays – This will help you customise operations and monitor levels.
