Water Heaters

A conventional venting natural gas water heater can heat water much faster than equivalent electric model. Storage tank models allow you to multi-task — do laundry, take a shower and even run the dishwasher simultaneously, while on-demand tank-less models can save valuable floor space. After space heating, water heating accounts for the largest portion of your total household energy use — about 15 to 20 per cent. That’s why it makes sense to choose the right natural gas water heater. Types of natural gas water heaters Residential natural gas water-heating systems fall into three basic categories. Each type has different features appropriate for different conditions. Our gas fitter and HVAC technicians will help asses any load requirements or venting for your Domestic Hot Water (DHW) system you choose.

Storage Tank Water Heaters

Storage tank water heaters are by far the most common in North America. They hold between 115 and 230 litres (30 to 60 US gallons) of hot water. Very sufficient for the needs of most homes. The water is stored in a large metal tank insulated to retain heat. Meeting supply and water-flow rates over short periods of time. Recovery for a tank gone cold is between 17 and 25 minutes.

Indirect Water Heaters

Indirect water heaters use heat generated by a central heating boiler and minimizing the number of heating appliances in the household. indirect water heaters circulates water through the heat exchanger or coil and stored in a cylinder shaped and sized like a conventional storage tank. While more expensive than storage tank heaters, they can provide higher capacity and greater efficiency. In fact, when an indirect water heater is used with a high efficiency boiler, the combination will provide the most efficient, least expensive over the life expectancy, method of water heating.

Power Vent

When a Gas Fitter is installing a Domestic Hot Water tank (DHW) system but doesn’t have a chimney, or must travel some distance, the power venting hot water tank may be a great option. Power vent Water heaters units use an electrically-powered fan or blower to remove exhaust from the flue gases from the hot water heater. If your water heater is installed in such a location a power vent water might be your only solution. This type of heater does not usually affected changes in the air pressure in a home, but can contribute significantly to building depressurization, affecting other combustion appliances.

Direct Vent

Direct vent systems don’t need a vertical chimney. They run, right-angled and horizontally through an outside wall. A direct vent system takes combustion air from the outside and vents the exhaust to the outside, using a two-way pipe. Because direct vent water heaters do not use air from inside the home for combustion, they will not affect, or be affected by, other appliances or changes in pressure inside the home. Ventilation of a house is a primary reason whether the heating or cooling system will reach equilibrium.

On-demand Water Heaters

Sometimes called tank-less or instantaneous water heaters, heaters water only as it is required. Since this on demand system heat water it does not need a storage tank full of hot water therefor has associated energy efficiencies. Compact design of the on-demand heaters has given the term wall hung boilers. These on demand systems can also supply radiant heating with a combination model. The hot water volume of some models may be too small to support more than one hot water appliance at a time, or you might have options available for additional heating applications such as an addition or retro fit so correct sizing is essential.


There are a number of venting options available to suit your installation. And questions to be raised about the appliances in the home being used now, does your house have an HRV or ERV? Check the manufacturer’s specifications for the HVAC equipment and hot water unit. Ask a registered gas fitting contractor to recommend the best venting design for your home is your best bet for a healthy efficient home.

Vertical (natural draft) Vent

The vertical vent, or conventional venting system can be shared with most standard or mid-efficiency furnaces or boilers. This style of venting draws warm air from inside the house for combustion and venting. Proper air supply is important to have, particularly if your home is airtight.

Power Direct Vent

A power direct vent is the same sealed combustion system as direct vent, but fan or blower-assisted to travel a longer distance. In some instances, there are two fans – one for outside air intake, the other for exhaust. It really is a combination of the direct vent and power vent system. And is used many times in commercial applications. With the sealed two-way pipe is used system it does not affect the Ventilation and equilibrium of the house.

Furnace Installation

A gas furnace is one of the best ways to heat your home. New high efficiency furnaces operate at a smoother more consistent heat than ever before. A New Gas Furnace will not only save you money from operating costs but will give you more even temperatures with no noise or high wind speeds coming from your ducting. New furnaces run on ECM motors that run at lower  speeds at a lower rate of power drawn.
