Types of Heating Systems (HS): Their Basic Differences and Advantages & Disadvantages

Electric furnaces for heating a house

Due to high CO2 emissions, sooner or later we have to think about choosing the optimal heating syst. for our home. To have the optimal temperature in the house, and at the same time, do not harm nature.

Every Canadian citizen consumes 2.8 tons of CO2 per year. coal, oil or natural gas. Of these, 2.1 tons of CO2 comes from personal consumption and 2 tons from the use of aircraft, cars and trains.

That is why it is important to choose a good HS for the future that will reduce CO2 emissions and minimize emissions.

In this article we will tell you what a heating syst. is and its types. As well as their advantages and disadvantages.

Fossil Energy: The Future or The Past?

While the trend reversal and transition to renewable energy should be successful in the future, we still get most of our energy from fossil fuels. Of course, this raises the question of how we want to make the energy transition and, above all, when.

In addition, energy must be used more efficiently, which in turn can lead to lower energy consumption. This should be done, for example, through the renovation and thermal insulation of buildings, energy-efficient household appliances and innovative heating systems.

Particularly in heating technology, new storage options are required when modern energy systems are used.

Renewable energy sources make sense especially in thermally insulated new buildings in order to keep the overall temperature level as low as possible, which in turn has a positive effect on energy costs.

Let’s take a closer look at what HS are.

HP

HPs are ideal for using heat from the air and the ground to heat buildings. They are equipped with a compressor and must be powered by electricity. However, HP can also be combined with a photovoltaic syst.

In addition, the heat pump draws energy for your HS directly from air, water or land, which in turn eliminates the need for long transport routes and thus protects the environment.

Modern Types of Heating Systems

Benefits Refrain from Using Fossil Fuels

  1. Energy is environmentally friendly and always available.
  2. Maintenance costs are very low.

Flaws

  1. The acquisition cost of a HP is relatively high.
  2. Sometimes permissions are required to install it.

Depends on the price of electricity at home, however economically it uses the energy of the sun to heat the house. Drinking and technical water.

With the help of a buffer tank, the heat from the syst. can be used and stored even more efficiently, but the heat output is somewhat lower in winter due to the lack of sundials. This shortfall can easily be offset by other renewable energy sources such as pellet heating.

Benefits of Free Solar Energy

  1. Pays for itself in a few years.
  2. Combination with other renewable energy sources is possible.
  3. Funding options and grants.

Flaws

  1. It is usually not possible to fully cover the heat demand.
  2. Installation depends on the sun.

North Wind Hvac Pellet heating system

Pellet Heating

Pellet heaters are also a good option for alternative heating. Thanks to wood pellets, the syst. works mostly automatically, but the fuel tank takes up a lot of space in the house.

Advantages

  1. High level of automation and efficiency.
  2. Balanced energy balance thanks to renewable raw materials.

Flaws

  1. Higher acquisition costs.
  2. Regular disposal of ash.
  3. Large storage space for pellets.

Combined Heat and Power Plants

Have been used in industry for a long time. Using gas turbines or internal combustion engines, they generate electricity, the waste heat from which can be used to heat buildings.

For private consumers, this alternative heating system really sounds tempting. However, to achieve a high level of savings, the heat demand must be very high.

Advantages

  1. Generates electricity and heat regardless of the current electricity price.
  2. Electricity may be paid extra.
  3. Fuel is used efficiently.

Flaws

  1. Economical only when heat demand is high.
  2. The acquisition is very expensive.

Hybrid Heating

This system combines several HPs at once in order to use their advantages, on the one hand, and compensate for existing deficiencies, on the other. The center of this heating is the buffer storage. This means that any excess heat can be used later.

Advantages of different heaters in one syst.

  1. Particularly environmentally friendly heating.
  2. Heat can be generated by yourself.
  3. Conversion is possible at any time.

Flaws

  1. The acquisition is very expensive.
  2. Requires large areas.

Fuel Cell

Although fuel cells are considered the HS of the future, their technology for private households is not yet fully developed. Heat and electricity are generated here as a result of a chemical reaction between oxygen and hydrogen.

Advantages

  1. Heat generation, hot water and electricity.
  2. High efficiency.
  3. Also suitable for low energy buildings.

Flaws

  1. Technically complex.
  2. Not tested in the long run.
  3. The acquisition is very expensive.

Modern HPs: not only environmentally friendly, but also more efficient

Due to rising electricity prices, buying an alternative heating syst. is certainly justified, even if the costs of acquiring it seem high at first.

Many systems such as solar thermal pay off in just a few years because they use significantly less energy than conventional syst., and heat and electricity are generated from solar energy. In addition, government subsidies can be claimed, further reducing acquisition costs.

Frequently Asked Questions About Indoor Air Quality in Ontario Homes

Why is indoor air quality worse in Ontario homes during winter?

Ontario homes are heavily insulated and sealed during winter to keep heat in, which dramatically reduces natural air exchange. This traps indoor pollutants – VOCs from furniture and cleaning products, pet dander, dust mites, mould spores, and combustion byproducts. The EPA estimates indoor air can be 2–5x more polluted than outdoor air in winter. Mechanical ventilation (HRV/ERV) and high-MERV filtration address this without wasting heat.

What MERV rating air filter should I use in my Ontario home?

MERV 8–13 is the recommended range for most Ontario homes. MERV 8 captures most dust and pollen. MERV 11–13 captures smaller particles including mould spores and some bacteria, which is beneficial for allergy sufferers. Avoid MERV 16+ filters on residential furnaces – they restrict airflow so severely they can damage your system. Always check your furnace manufacturer’s specifications before upgrading filter ratings, and change filters every 1–3 months.

What is the ideal indoor humidity level for an Ontario home in winter?

Health Canada recommends maintaining relative humidity between 30–55% in Canadian homes year-round. In Ontario winters, homes with forced-air heating can drop to 10–20% RH without humidification. Below 30% RH causes dry skin, irritated sinuses, increased susceptibility to viruses, and static electricity. Above 55% RH promotes mould and dust mite growth. A furnace-mounted whole-home humidifier is the most effective solution – portable units are inadequate for larger homes.

Are whole-home air purifiers worth the investment?

For Ontario households with allergy sufferers, asthma, or pets, a whole-home air purifier (HEPA or electronic polarized media filtration installed in the duct system) offers significant improvement over standard furnace filters. Systems like the Aprilaire 5000 or IQAir systems capture particles down to 0.3 microns. UV air purifiers (like Fresh-Aire UV APCO) also reduce bioaerosols, mould, and odours. The investment of $700–$2,500 installed is often returned through reduced allergy medication and sick days.

Do I need an HRV or ERV for my Ontario home?

If your home was built after 2012 or has been significantly air-sealed, it almost certainly has or needs an HRV (Heat Recovery Ventilator). Ontario Building Code requires HRVs in new construction for this reason. An HRV exhausts stale air while recovering 70–80% of the heat, then brings in fresh outdoor air. Without adequate ventilation, moisture and pollutant levels rise significantly. If your home feels stuffy despite running the furnace, an HRV assessment is a good first step.

Can a humidifier on my furnace cause mould?

A poorly calibrated or malfunctioning furnace humidifier can introduce too much moisture, leading to condensation on cold surfaces and mould growth – particularly around windows, in attics, and in poorly insulated areas. The key is setting the humidistat correctly: start at 30–35% RH in deep winter and adjust based on window condensation. Have the humidifier serviced annually (replace water panel/evaporator pad, clean the unit) to prevent scale buildup and bacterial growth.

What causes my home to smell musty when the furnace turns on?

A musty smell at furnace startup is usually caused by dust burning off the heat exchanger after summer dormancy (normal and temporary), mould growth in the ductwork or on the evaporator coil, a dirty or saturated furnace filter restricting airflow and causing moisture buildup, or standing water in the condensate drain. A seasonal furnace tune-up includes a coil cleaning and duct inspection that typically resolves this. Persistent musty smells warrant a professional air quality inspection.
