As you embark on the journey of installing a tankless water heater in your home, you may wonder about the first critical step to take. This article is crafted just for you. It meticulously outlines the initial yet crucial action to take before starting your installation chore. This essential step can make your task seamless or turn it into a complete mess. So let’s uncover that initial yet significant process together, shall we?
Understanding Tankless Water Heaters
Let’s jump right into understanding what tankless water heaters are all about. Keep in mind, it’s vital to know your wares before investing your valuable time and money!
Definition of a tankless water heater
A tankless water heater is, quite simply, a water heater that doesn’t involve a big bulky tank. Instead, it heats the water on-demand, meaning it only heats water when you need it to. This is quite different than traditional water heaters that continually heat stored water, regardless of whether it is to be used immediately or not.
How a tankless water heater works
your tankless water heater works through a process known as flow sensing. Once you turn on the hot water tap in your home, the flow of water is detected by the sensor in the tankless unit, which triggers the heating elements to heat the water. This gives you hot water exactly when you need it and stops when you turn the tap off — no more waiting for the tank to fill or paying to heat water before you’re ready to use it!
Benefits of a tankless water heater
The benefits of a tankless water heater are numerous. Not only do they help conserve water, but they can be more energy-efficient as the water is only heated when required. Additionally, they take up less space, have a longer lifespan, and offer a constant supply of hot water. Plus, you don’t have to worry about a tank leak!
Determining the Need for a Tankless Water Heater
Making the switch to a tankless water heater can be quite a decision. Let’s make it easier by helping you determine your hot water needs.
Evaluating your current hot water usage
Start with evaluating how much hot water you use daily. This could be through the number of hot baths, loads of hot laundry, dishwashers runs among other uses of hot water in your home. Having a clear picture of your usage can guide the kind of tankless water heater you’ll need.
Assessing the efficiency of your current water heater
Next, assess the efficiency of your current water heater. If it’s consuming more energy than it should or frequently needing repairs, it might be time for a switch. Also note how old your current unit is; traditional water heaters typically only last 10-12 years.
Considerations for making the switch to tankless
Now, ponder on why you’re considering the switch to a tankless water heating system. Is it for space-saving or do you crave the continuous hot water supply? Tankless units are more expensive than tank models, but they could pay off in the long term when considering energy savings and unit lifespan.
Choosing the Right Tankless Water Heater
Now akin to choosing your favorite dish in a buffet, you’ve got to put into consideration what you need the most.
Assessing volume needs
In selecting a tankless water heater, consider the amount of water you typically need to be heated simultaneously. For instance, do you frequently have multiple showers running at once or use the dishwasher while taking a shower?
Considering energy source options
Also, you need to consider the energy source with which you’re most comfortable. Tankless units are either electric or gas-fired. Your choice could affect your energy bills as well as the unit installation costs, given that gas units require venting.
Understanding size and space requirements
With space being one of the benefits of a tankless water heater, pick the size of the unit that meets your needs and fits your allotted space. Remember, however small it might be, it should be able to meet your maximum hot water requirement.
Going Over Local Building Codes
Before making your purchase, cross the Ts and dot the I’s regarding building codes in your area.
Understanding the city building regulations
Different cities have different regulations and requirements for installation of tankless heaters. For instance, some cities may require anti-scalding devices or specific types of venting.
Identifying required permits
Check if any permits are required before you begin work. Some cities require you to acquire a permit before any plumbing or electrical work.
Checking the city’s restrictions on tankless models
Lastly, check if there are any restrictions concerning types or brands of tankless water heaters. Ensure the model you like is compliant for peace of mind.
Inspecting the Installation Area
The preparation phase is vital, ensure you’ve checked all the necessary points.
Ensuring enough space for the tankless water heater
Even though tankless water heaters are smaller, they still require enough space for proper installation and operation. Ensure the space selected is not too cramped.
Checking for necessary connections (gas, electrical etc.)
Check your installation space to make sure the necessary electrical or gas connections are available. Gas models need access to a gas line, and likewise, electric models will need proximity to an electrical circuit.
Considering proximity to the main water line
Also, consider where your unit will be located in relation to your main water line. The closer to it, the easier the installation process.
Planning for Proper Ventilation
Ventilation is key, do not overlook it!
Understanding the importance of ventilation for tankless units
Your gas-fired tankless water heater will need adequate ventilation to ensure safe operation. Without it, there could be potential for hazardous, lethal gas build-up.
Planning for vent placement
Plan for vent placement, making considerations for the particular unit you choose. Some models may allow for direct venting out a side wall, while others may require traditional vertical venting.
Checking existing ventilation and exhaust systems
Examine your existing ventilation systems to ascertain if they’re suitable and adequate for your new unit. In some cases, new venting may need to be installed.
Ensuring Adequate Water Pressure
Nobody likes weak showers, so let’s address water pressure!
Learning how tankless units affect water pressure
Tankless water heaters can affect water pressure – but in most cases, this is minimal, if there’s even a notable change at all. The flow rate of your unit will play a larger part in this.
Checking existing water pressure
Before installing, check your home’s existing water pressure. If it’s too low, a tankless water heater may not operate efficiently.
Planning for potential water pressure adjustments
Planning for potential pressure adjustment is key. Depending on your home’s current water pressure and the tankless unit’s specifications, you might need to install a water pressure booster.
Accounting for Energy Requirements
Now let’s do some maths.
Assessing your home’s current energy capacity
This is where you assess how much energy your household currently uses – which can include everything from lighting to appliances. Knowing this can guide your choice between a gas or electric unit.
Understanding the energy demand of a tankless unit
Know the energy demand of the tankless water heater you’re considering. Energy usage greatly depends on your hot water behavior. The more often and the bigger the volume needed, the higher the energy demand.
Planning for potential electrical or gas upgrades
If your household doesn’t have the necessary capacity to support a new tankless water heater, you might need to plan for some upgrades. These could include upgrading your gas supply line for a gas unit or your electrical capacity for an electric unit.
Considering the Cost of Installation
Now we’re down to the nitty-gritty – the cost!
Understanding the costs associated with tankless units
The costs associated with purchasing and installing a tankless unit are higher than those of traditional water heaters. However, they have longer lifespans and provide energy savings over time which can offset the initial cost.
Budgeting for the initial purchase
Ensure you have budgeted enough for the initial purchase of the unit. Keep in mind the costs of any potential upgrades and necessary accessories.
Factoring in the cost of professional installation
It’s also important to factor in the cost of professional installation. Unlike traditional water heaters, tankless units require professional installation due to the complex nature of the job.
