What Size of Hot Water Heater is Right for My Home?

Anyone who’s gotten halfway through a shower only to notice there’s no more hot water can tell you the importance of having a hot water tank that’s large enough for your needs. Aside from helping keep you clean, the hot water tank is also how you keep your household running smoothly from laundry to dishwashing. So how can you tell what size is right for your home?

How to Determine the Best Water Heater Size for Your Home

The average residential hot water tank typically ranges anywhere from 40-75 gallons. Choosing the right size of tank for your home depends on a variety of factors: the square footage of your house, the size of your family or number of roommates, your water usage, your appliance usage, and more. However, choosing a tank size really comes down to two key factors.

First Hour Rating (FHR)

The First Hour Rating (or FHR as it’s more commonly known) refers to how many gallons of water are heated in an hour. Often you can find this listed on a sticker on the water heater. This matters because the higher the FHR, the faster you’ll be able to replenish that hot water supply. The more water you need at once, the higher the FHR you’ll want which brings us to our second key factor.

Peak Demand

Peak demand is the amount of hot water you require during the highest usage points. Think about the times when you’re showering upstairs, someone is showering downstairs, someone else is washing their hands in the kitchen, and the washing machine is going in the laundry room — that’s peak demand.

As a rule of thumb, it’s recommended that you pick a tank that is rated with 1-3 hours of your peak gallon demand. Curious to learn more about how to calculate peak demand and FHR? This article from the U.S. Department of Energy has a handy calculation table at the bottom. Try inputting your current numbers to learn more!

How to Tell When Your Hot Water Tank is the Wrong Size

Many families notice a decrease in hot water supply as the kids start to age and take longer showers, laundry loads happen more often, and running the dishwasher is a more frequent occurrence. It may point to the fact a family has outgrown its hot water tank. Moving into a new home? We recommend checking the First Hour Rating when you move in and keeping an eye on your hot water supply as you become settled.

It’s important to note though, bigger isn’t always better. Having a hot water tank with more gallons than you need can result in higher energy bills so although it’s tempting to just get the largest one available to you, we strongly recommend doing the calculations first.

Being Smart with Water Usage

One way to make your hot water supply go further is to space out usage. For example, if four people are taking showers in the morning, perhaps hold off on running the dishwasher until later in the day. A little planning can make your hot water supply go a long way.

Getting the Most Out of Your Water Tank

If after reading this, you’ve concluded that you need a new water tank, we’d first advise having a professional come to inspect your existing hot water tank first. This ensures that you’ve done due diligence in maintenance and aren’t paying to replace a unit that may just need a repair or cleaning.

We say it a lot but it’s always applicable: when it comes to home maintenance, an ounce of prevention is worth a pound of cure. Taking care of your water tank regularly will help to extend the life of whatever water tank you do end up buying. That’s why we’ve written this handy article on the 5 easy ways you can maintain your hot water tank.

Not sure if you have the right water tank for your space? Give us a call! We’re happy to help walk you through the process, find and install the right one, or help you best maintain the one you already have. We can also share options involving on-demand hot water heaters – an increasingly popular choice for those seeking energy-efficient alternatives.

Advanpro must be immediately notified of any install issues. The guarantee applies for 3 months, starting from the installation date. The guarantee no longer applies if, at any time after the quote or installation, modifications are made to the home that impact heating requirements.

A/C Tune Up

Regular preventative maintenance improves efficiency and extends the lifespan of your air conditioning system, with the following benefits:

 

  • Reduced electricity bills and operating costs. When the unit operates as designed, electricity usage is reduced.
  • Maximized cooling capacity. Home comfort on the hottest of days with minimum run time.
  • Minimized repair bills. Detect and fix small problems before they get worse.

HRV Cleaning

Most homes built in the last few years have a Heat Recovery Ventilator (HRV), which efficiently replaces stale indoor air with fresh outdoor air, all year round.

 

As with any other air-handling equipment in your home, your HRV should be cleaned regularly to ensure the best possible indoor air quality.

 

If you aren’t sure if you have an HRV, call our team to find out how you can tell.

Duct Work Sanitizing

If you or your loved ones suffer from respiratory issues or allergies, or you’re concerned about the quality of the air that you are breathing, then our sanitizing treatment will give you the reassurance that your ductwork is sterile and free of debris that could negatively impact your respiratory and overall health.

 

Microban is our hospital-grade sanitizing solution, which kills 99.99% of germs, viruses, funguses, molds, and other pathogens.

 

We also offer Benefect, an all-natural sanitizer made from plant extracts, which also kills 99.99% of germs, viruses, funguses, and molds. ​

Exhaust Flu Stack Cleaning

Mid-efficiency furnaces produce a sand-like, mildly-corrosive byproduct. This substance condenses in the exhaust flu stack and collects over time near the inducer/venter motor, restricting exhaust gas flow. Eventually, it enters the inducer motor and causes premature wear on the furnace.

 

Exhaust flu stack cleaning removes the build-up to reduce the chance of motor failure and maximize the life span of your furnace. Preventative maintenance ensures your furnace runs efficiently all Winter long — without costly no-heat emergencies. 

A/C + High-efficiency Bypass

The secondary heat exchanger in a high-efficiency furnace or A/C coil has delicate, closely spaced fins that must be protected during your furnace and duct cleaning.

 

For furnaces that require a bypass, we temporarily install a filter above the heat exchanger or A/C coil, and position our duct vacuum above the filter.

 

This bypass procedure prevents damage by ensuring all dust and debris in your supply duct work is collected before reaching the heat exchanger or A/C coil.

 

Standard furnaces without A/C don’t have secondary heat exchangers or A/C coils and don’t require the bypass procedure.

Furnace Tune Up

Regular furnace tune ups are essential to maximizing the lifespan and efficiency of your furnace, so you can rely on it to keep you warm all Winter long.​

 

During our 30+ point inspection, we check all furnace systems to identify components that are worn out and need replacement. Replacing parts before they break — preventative maintenance — maximizes heating efficiency, avoids no-heat emergencies, and saves on costly service calls. 

 

Home furnaces can last for 20 years or more if well-maintained. A professional furnace tune up every two years helps to preserve your investment for decades.

Reverse Octopus Whip Tool

The reverse octopus whip has eight 16” flexible tentacles, which whip around blasting high-pressure air in all directions as it moves through your duct work.

 

The tool agitates and dislodges the most hard-to-reach dust, debris, and contaminants, moving them toward our duct vacuum for collection and disposal.

Brush Cleaning Method

Our high-speed rotary brushing equipment sweeps the entire interior surface of your duct work, ensuring that all dust, debris, and pet hair are vacuumed away.

 

Physically cleaning the entire length of your duct work ensures that no contaminants are left behind, increasing your indoor air quality and peace of mind.

Dryer Vent Cleaning

Dryer fires are a top-five cause of house fires. Cleaning your dryer vent regularly greatly reduces the chance of a dryer fire, plus the following benefits:

 

  • Reduces clothes drying times
  • Lowers utility bills through greater efficiency
  • Extends the life span of your dryer
  • Lessens the amount of allergens in your house

Back Skipper Tool

The back skipper is a 1” diameter rounded ball connected to a long, flexible high-pressure airline.

 

The 1” ball has jets that discharge high-pressure air, pulling the tool and airline through the length of your duct work.

 

The high-pressure air moves the dust and debris toward our duct vacuum, where it is collected for disposal.​
