Considering the move? Tankless water heaters also known as waterless tank heaters or on-demand water heaters are the future of residential hot water. A tankless water heater does not heat and reheat a large, stored tank of water but instead, it heats and only turns on when you turn on a hot tap that provides you with an inexhaustible, continuous flow of hot water at the point you need it.
BOS Plumbing and Drains has extensive experience in installing tankless water heaters, both gaseous (natural gas and propane) and electric, in all the major brands.
Advantages of upgrading to a tankless water heater:
What our tankless water heater install includes:
If you’ve been searching for a tankless water heater install near me, BOS Plumbing and Drains delivers the expertise and care your home deserves.
Among the questions we constantly hear is: Should I use a regular hot water tank or should I upgrade and use a tankless water heater? The truthful answer is it will depend on your home, your money, and your long-term objectives. The following is a breakdown of its clear form:
| Factor | Traditional Hot Water Tank | Tankless Water Heater |
| Upfront Cost | Lower | Higher |
| Operating Cost | Higher (standby heat loss) | Lower (on-demand only) |
| Hot Water Supply | Limited by tank capacity | Unlimited on demand |
| Lifespan | 8–12 years | 15–20 years |
| Space Required | Large floor footprint | Compact, wall-mounted |
| Installation Complexity | Standard | Moderate (may need upgrades) |
| Energy Efficiency | Standard | High |
| Best For | Budget-conscious installs, larger families with consistent usage | Long-term savings, smaller households, eco-conscious homeowners |
Not sure which is right for you? Our technicians will walk you through a no-pressure assessment during your appointment and give you an honest recommendation based on your actual situation.
In the GTA, the number of homeowners that are replacing their old systems of water heater tanks with new models of tankless water heaters that are energy efficient is on the rise. As utility rates go up and more people seek up to date plumbing systems, tankless units are proving to be a good long term investment to many families.
A tankless water heater will heat only the amount of water required, thereby saving money on monthly energy bills due to less standby heat loss. It is also suitable in busy families, where several showers, laundry, and dishwashing processes must occur all day long because it offers an unlimited amount of hot water. Tankless systems are small devices, unlike bulky hot water tanks that are mounted to the wall, which can help release space in the basement or utility room.
The professional tankless water heater install is also an option of many homeowners since these types of systems tend to outlive most traditional tanks, and the chances of having a sudden leak or flood out of a tank are minimized. In case you are not sure that switching is the right choice to your property, BOS Plumbing & Drains can evaluate your home, use requirements and budget and advise you on the best option.
One of the major choices when it comes to water heater installation or replacement water heater is fuel type. BOS Plumbing and Drains installs and repairs units of all types of fuel:
The most widespread option in Canada. Gas water heater tank and tankless water heater units are fast to heat water and tend to be cheaper to use in comparison to electric counterparts. These need to be well vented and connected to a gas line.
Electric units are also less complicated to install (no venting is needed) and a good choice in areas which may not have gas lines. Electric tankless water heater models are highly efficient in energy consumption although the operating costs are usually high.
Like natural gas, propane units are suitable to rural properties or homes not linked to municipal gas lines. BOS deals with water heaters installation and water heater repair of both tank and tankless water heaters.
The heat pump water heaters use the thermal energy in the air around them to heat water, which is why they are also one of the most energy-efficient. They adapt well in mid temperatures and areas that are well ventilated. Our team will be able to recommend whether it will fit in your house.
It is just as important to get the correct size unit as it is to get the correct type. A small unit will leave your family with insufficient hot water; a large unit will use more energy and money. A rough guide to the size of a conventional water heater tank:
| Household Size | Recommended Tank Capacity |
| 1–2 people | 30–40 gallons |
| 3–4 people | 40–50 gallons |
| 5–6 people | 50–60 gallons |
| 6+ people | 60–80 gallons |
The size of tankless water heaters is calculated by the number of parallel hot water outlets and the necessary flow rate (in gallons per minute / GPM). This calculation is done on your behalf by our technicians in the assessment ensuring that your tankless water heater install is exactly right to your home demand.
Since our team has been repairing water heaters near me for over 20+ years, we know the exact reasons as to why most water heaters fail and more importantly how to repair them.
The calcium and magnesium deposited in your water heater tank at the bottom of the tank create an insulating layer that makes the heating element in your water heater work harder. In the long run, this will result in overheating, loss of efficiency and early breakdown.
Prevention: Flushing of tanks annually and in hard water regions, installation of a water softener.
A sacrificial metal rod within your hot water tank is the anode rod which captures corrosive minerals and shields the lining of the tank. When empty, it corrodes internally, causing the tank to corrode.
Prevention: Anode rod inspections and replacement every 3-5 years.
High water pressure (more than 80 PSI) puts a strain on your water heater tank, connection and pressure relief valve which hastens its wear and creates leakages.
Prevention: A pressure-reducing valve (PRV) may be installed in case the pressure in your house is always higher than it should be.
Most of the water heater repair calls that we get are related to improper initial installation, improper venting, undersized gas lines, loose connections, or non-compliant installations. These problems result in frequent failures and may be safety risks.
Prevention: Have a licensed plumber install the water heater at the very beginning.
A majority of the homeowners do not service their water heater tank until it breaks. Small problems can be identified during annual or biannual inspections: a weakening component, a corroding joint, a broken thermostat before they cost a lot to fix. BOS Plumbing and Drains can provide maintenance visits to ensure that your system is operating efficiently.
The design life of traditional hot water tank units is 8-12 years. Tankless water heater systems last 15–20 years with proper maintenance. When your unit is nearing or has already exceeded the life-span that it is supposed to have, then replacing the water heater parts is just a temporary solution to a permanent problem. By that time, it is wiser to replace the water heater for financial consideration.
Your hot water heater will usually give you warning signs before it completely fails. Catching these early can mean the difference between a simple water heater repair and an expensive emergency replacement.
