Purchasing a brand new furnace is a serious decision these days because there are so many options, including different brands, models, and variations, technical capabilities, furnace types, and efficiency ratings. However, one of the most important factors to consider when choosing a new furnace is the size that is best suitable for your home in Newmarket.

A Building Permit from Newmarket Town Government is usually not required for furnace replacement if no building alterations are taking place.

Installing a properly sized furnace requires more than simply calculating your home’s square footage. There are various aspects to consider while sizing a new gas furnace. Now we’ll go over what those factors are, why properly sizing a furnace is so important, and how to find a furnace that’s the right size for your location, environment, and comfort needs.

The goal of this article is to guide you in choosing the required size of furnace for your heating needs. It is calculated by taking the required heating BTU per square foot for most homes and your climate zone. Our heating BTU calculator takes these critical things into consideration, allowing you to give an answer for common questions as “how many BTUs to heat a home?” or “What size furnace do I need?”

The BTU per square foot heating rule of thumb varies greatly depending on your climate and the area of your house or room you wish to heat up. Newmarket is located in Zone 2.

Why choosing the best Furnace Size Is So Important?

While it may be appealing to choose a smaller furnace to save money on the purchase or a larger furnace to increase space-heating, we should follow the Golden Mean rule with furnaces, just as we should with many aspects in our lives: you need one that is just right for your home.

A furnace which is far too powerful will cycle irregularly. This is problematic because it will generate hot and cold zones around the house, decrease efficiency, require additional maintenance, and shorten the life of the furnace.

An undersized furnace will operate non-stop and won’t keep the temperature in your home at comfortable levels. The additional workload will also increase your energy bills, inrease the probability of maintenance issues, and also shorten the lifespan of your heating unit.

Another drawback of having a furnace that is the incorrectly sized is that it will reduce the overall efficiency of your heating system.
The AFUE (Annual Fuel Utilization Efficiency) is the thermal efficiency measurement of a furnace based on normal operation. The AFUE tries to represent the equipment’s actual, season-long average efficiency, taking into account all operating factors.

You won’t be able to get the efficiency rating you paid for if your furnace runs continuously or irregularly because it is the wrong size. That means more energy use and higher heating expenses.

Your furnace must be correctly sized for your home in order to perform at the efficiency level it is rated for.

How many BTU do I need for my house in Newmarket?

That is a crucial question that must be answered correctly. On the coldest winter days, a furnace that is way too undersized will not heat your home properly. Areas further away from the furnace may become uncomfortably cold in your home.

An oversized furnace will waste large amounts of energy, and create hot patches around vents close to the furnace before the heating cycle stops.

When you talk about furnace size, you are not talking about the actual physical dimensions of the unit. Rather, the size of a furnace is determined by its heating output and the amount of heat it can provide.

The output of a furnace is often measured in British thermal units (BTU) per hour. A BTU is a unit of measurement for energy, particularly the amount of energy necessary to raise the temperature of one pound of water by one degree Fahrenheit. Heat is now understood to be the same as energy. The joule (J) is the current SI unit for heat and energy; one BTU equals about 1055 J.

Furnace BTU

You need to remember, that “BTU/h” is sometimes abbreviated to just “BTU”. The modern unit of power for heating and cooling systems is the watt. 1000 BTU/h is approximately 293.1 W.

Some manufacturers have started to calculate furnace size in MBHs rather than BTUs. One MBH is 1000 BTU per hour, then you’re still using the same unit: 60 MBH is equal to 60000 BTU.

The general BTU per square foot heating rule of thumb varies from 30 BTU per square foot to 60 BTU per square foot based on your climate zone. That is a significant variation, with one furnace being twice as powerful as the other, so the size factors are explained here to help you in how to size a new furnace for a house.

A bigger furnace, such as one with an output of 120000 BTU per hour, will provide enough heat for a larger space. A smaller furnace will have a smaller BTU capacity, such as 40000 BTU per hour, and would be suitable for only a smaller pace.

Calculating BTU requirements for a house

Let’s start with this useful map. The climate becomes progressively colder from zone 1 to 3.

Find your location on the map. If you’re on or close the border between two zones, choose the higher number, the cooler zone.

Canada climate zones

Take the square footage of your home. If you don’t know it, you can look up the blueprint of the house, or measure rectangles within your home. Multiply the width by length for each rectangle and add them together.

It is not quite accurate, but nevertheless very useful for our purposes. While you shouldn’t use this calculation to make a final decision about furnace size, you can use it to get an idea of the size range to look at when you buy a new furnace. You can get a basic estimate using the square footage of your house.

The general rule of thumb is that you need between 30 and 60 BTU per square foot. Depending on your climate zone, you can determine how many BTU per square foot you need.

As you live in Newmarket, Ontario (Zone 2), in a home which is 2000 square feet. The chart would tell that you probably need a 90000 BTU furnace.

This value is only a rough approximation to demonstrate how these previously mentioned factors can affect the furnace size you need to buy, how many BTUs needed to heat a house. There are several additional factors that can affect the final furnace sizing calculation.

We need to inform people living in Stouffville on how to prepare for and avoid house fires. Heating systems are one of the leading causes of house fires, second only to kitchen equipment, according to data, therefore it is essential to be aware of furnace safety. Fortunately, there are some simple precautions you can take to minimize the possibility of a fire and keep your house and family safe and prepared in case of emergencies.

Furnace Fire Causes

Furnaces may get very hot, especially if they are used constantly during the wintertime. Because of the heat, you should keep the area surrounding your furnace free of clutter. The majority of Stouffville fire deaths are the consequence of flammable objects being left close to a heat source, generally the gas furnace. To reduce the risk of fire, you should leave at least three feet of space around your furnace free.

You need to look for discoloration or heat on the walls surrounding the furnace. If you discover any of these indications, contact Air Tech Toronto to have a professional heating specialist inspect your gas furnace.

Carbon Monoxide Awareness in Stouffville

As a byproduct of burning fuel for heating, your gas furnace may emit potentially hazardous gases. Some of these gases, such as carbon monoxide, are odourless, making them extremely dangerous. When typical fuel-burning appliances and equipment which burns natural gas, oil, wood, propane, and kerosene do not get enough oxygen to burn, this odourless gas is generated as a byproduct of insufficient combustion. Furnaces, though, are intended to safely exhaust harmful gases outdoors. To minimize carbon monoxide buildup in the home, make sure that your vents are clean of any clogs or dirt.

Carbon Monoxide, known by its chemical fourmula of CO, is a toxic gas that cannot be seen, smelled, or tasted. CO is also known as the “silent killer.”

Carbon monoxide may accumulate in the house, particularly in enclosed areas, and this can have devastating consequences on humans and all living creatures.

CO has warning signs by how it affects humans. CO poisoning causes flu-like symptoms, such as:

  • headache
  • nausea
  • dizziness
  • fatigue
  • burning eyes
  • confusion
  • disorientation
  • drowsiness

CO poisoning affects your body’s ability to absorb oxygen. It can cause brain damage and death in extreme situations. The elderly, children, and those suffering from heart or respiratory problems may experience the affects sooner than the others. Even low quantities of CO gas might be extremely dangerous.

The best solution to protect yourself and your family in Stouffville against carbon monoxide poisoning is to eradicate it at the source. When it comes to CO safety, here is a checklist to take into account.

  • Have fuel-burning appliances installed by a professional Air Tech Toronto technician with over 35 years of experience.
  • Have all your fuel-burning appliances and vents are inspected annually.
  • Keep chimneys clear of small animals, leaves, and other debris to ensure proper ventilation.
  • Ensure your furnace is inspected for adequate ventilation.
  • Install a working carbon monoxide alarm near all sleeping areas in your home.
  • Remember to test your CO alarms once a month by pushing the test button on the unit.

Small Animals Can Cause a Furnace Fire

As leaves and tiny animals might sneak into your vents, it’s a good idea to make it a routine practice to check them frequently. If you have a cat, you may have seen it resting on the heating vent that delivers air to your ducted furnace. It may not be cold enough in the home or outside yet, but cats enjoy resting on furnace vents. Cats, like any other animal, are always looking for ways to feel relaxed. You may believe that your cat is intelligent enough to avoid every risk in your home on their own, but it may or may not recognize real danger. There are a number of HVAC hazards in your basement, including your gas furnace. Sitting near or on the furnace should not be encouraged.

We need to remind Richmond Hill residents how we can prepare for and prevent home fires. Since statistics show that heating systems are one of the main causes of home fires, second only to cooking equipment, it is important to be aware of furnace safety. Fortunately, there are some basic tips that can help to reduce the risk of fire and keep your home and family safe and prepared for emergencies.

Furnace Fire Causes

Furnaces can become hot, especially when they are in constant use during winter. This heat means that you should keep the area around your furnace clear. Most of fire deaths in Richond Hill are the result of combustible materials being left near a heat source, usually a furnace. Ideally, there should be at least a three foot area of space around your furnace to reduce the risk of fire.

You should also check the walls near the furnace to check for discoloration or heat. If you notice any of these signs in the vicinity, call a professional heating expert from Air Tech Toronto to check for gas furnace dangers.

Carbon Monoxide Awareness in Richmond Hill

As a side effect of burning fuel for heat, your furnace will produce potentially dangerous fumes. Some of these fumes, including carbon monoxide can be odorless, which makes them especially dangerous. This odourless gas is produced as a byproduct of combustion when common fuel-burning appliances and equipment that use natural gas, oil, wood, propane and kerosene, don’t get enough air to burn up completely. Fortunately, furnaces are designed to safely vent these fumes outside. Therefore, to avoid carbon monoxide build up in house, it is important to ensure that your vents are clear of any obstructions or debris.

Carbon Monoxide, also known as CO, is a poisonous gas that you can’t see, smell or taste. CO is often referred to as the “silent killer”.

Carbon monoxide at home can build up, especially in a confined room or space – and this can lead to toxic effects on humans and pets.

CO has warning signs by how it affects humans. CO poisoning causes flu-like symptoms, including:

  • headache
  • nausea
  • dizziness
  • fatigue
  • burning eyes
  • confusion
  • disorientation
  • drowsiness

CO poisoning makes it difficult for your body to absorb oxygen. In severe cases it can cause brain damage and death. The elderly, children and people with heart or respiratory issues may feel the effects sooner than others. Even small amounts of CO gas can be dangerous.

The best way to ensure that you and your family in Richmond Hill are not exposed to carbon monoxide is to eliminate this poisonous gas at the source. Here is a list to follow when it comes to CO safety.

  • Have fuel-burning appliances installed by a professional Air Tech Toronto technician with over 35 years of experience.
  • Have all your fuel-burning appliances and vents are inspected annually.
  • Keep chimneys clear of small animals, leaves, and other debris to ensure proper ventilation.
  • Ensure your furnace is inspected for adequate ventilation.
  • Install a working carbon monoxide alarm near all sleeping areas in your home.
  • Remember to test your CO alarms once a month by pushing the test button on the unit.

Small Animals Can Cause a Furnace Fire

Leaves and small animals can get into your vents, so it is a good idea to establish a routine of checking your vents are clear. If you’re a cat owner you may noticed your cat sitting on the heating vent that distributes air for your forced air furnace. It might not even be that cold in the house or outside yet, but cats love sitting on furnace registers. Cats like any other animal are constantly searching for comfort. You might think that your cat is smart enough to avoid all danger in your home on their own, but it may or may not understand where danger lies. In your basement there are a number of HVAC dangers including your furnace. Sitting near or on the furnace shouldn’t be something you encourage. There is always chance they get too close to the pilot light or brush up against a hot tube or duct. Cat and small animals pose a furnace fire hazard.

One of the most significant investments you can make is buying your house. But it doesn’t mean you should invest in it unless it will pay off or enhance your living conditions. With that in mind, let’s take a deeper look at a home energy retrofit programs and how installing a new Bosch residential heat pump might not be as expensive as you think.

What is a heat pump?

Let’s make things as clear as possible. A heat pump is a type of HVAC system. It may be used to heat or cool certain rooms in your house. While the word “heat pump” may seem confusing, it is a description of what the system does.

To summarize, in the winter, the heat pump takes warm air from the outside and distributes it inside. In the summer, though, it works in reverse, taking warm air from indoors and expelling it out of your home to keep you nice and cool.

Heat pump vs. furnace

While they both serve the same function throughout the winter season of the year, there are a few significant differences between these two units, which include:

  • Furnaces are often bigger and occupy more space to meet the requirement for a larger system to create heat – as opposed to a heat pump, which brings heat in from the outside.
  • Heat pumps may both heat and cool your home, resulting in a two-in-one system.
  • Furnaces are central units and require a proper duct system all across the house to function properly.
  • Heat pumps use far less energy.

Now that we’ve covered the fundamentals, let’s look at the Canada Greener Homes Grant and how you may receive a rebate from the government for a heat pump.

How to get Government of Canada rebates for home renovations

It can be expensive to upgrade your house. Indeed, there are low-cost improvements and retrofit solutions that have a significant influence on your home’s value. However, a retrofit and perhaps some cosmetic modification of your property are not the same thing.

We all know that remodelling generally refers to any sort of basic house improvement, but what exactly does retrofit mean? It typically means you’ve moved beyond the realm of do-it-yourself. A retrofit typically refers to an upgrade to your home’s primary systems. They require the services of an expert to analyze and implement energy-saving improvements. If you’re wondering how you can receive free money from the Canadian government for retrofit solutions, there’s a home remodelling grant for that.

The Canada Greener Homes Grant is the most recent of Canada’s energy efficiency initiatives, and it was established to reward homeowners throughout the country who make their homes more energy efficient with up to $5,000 (plus $600 in some circumstances). But, exactly, what does that necessarily mean? It’s not as frightening as it appears. There are a couple of measures to take. Just keep in mind that you won’t really be able to DIY this one yourself. It requires:

  • An inspection/green home energy audit to evaluate your home’s current efficiency
  • Official recommendations that you can follow
  • Installation of at least one of the eligible recommendations (like Bosch climate 5000 installations)
  • And finally, a follow-up inspection/green home energy audit to see if your home’s efficiency has improved

Naturally, since this is a more significant job, you wouldn’t want to do it yourself and risk not being eligible for the rebate. For instance, installing the Bosch Climate 5000 is not something you can do using YouTube. To complete the task correctly, a professional installer with expertise and qualified equipment is required. Therefore, if you’re considering of improving your home’s HVAC system to take advantage of the energy efficiency retrofit initiative, you should consider hiring an expert.

Why choose Bosch thermotechnology?

Choosing a Bosch equipment is always a wise option since they are one of the best and most efficient heat pump manufacturers on the market today. It’s difficult to think of a better alternative when filing for a heat pump government rebate, with a better model and a 10-year Bosch warranty, and now that it’s part of the Canada energy savings incentive program. After all, when it comes to upgrading your home’s HVAC system, you want to be sure you have the ideal heating and cooling system. However, there are a few additional factors.

Air handler unit that’s whisper quiet

One disadvantage of the heat pump vs furnace argument is that furnaces are typically quieter. Yet, in a short period of time, technology has advanced significantly. The Bosch climate 5000 specifications for the air handler, for example, guarantee that it will not get louder than around 20 dB, which is as quiet as whispering or some rustling leaves.

High efficiency heat pump

An another major pro that has recently emerged from the Bosch climate 5000 reviews is that it is exceptionally energy efficient. This system was designed to outperform alternative heating and cooling choices, in addition to having a high SEER rating. This is because these air handlers are best suited for spot heating and cooling, resulting in reduced resource consumption. That means you may take advantage of Canada’s energy efficiency incentives, as well as enjoy pleasant temperatures and lowered monthly expenses.
