Gas fitters 1-888-WE-GAS-4U have demonstrated a mastery of our trade. At All Our location we have extended training for our HVAC service professionals to offer you even better service.
We install all your gas pipes, gas lines, and heating and cooling products by reading blueprints, drawings, and specifications to determine the layout of water supply, waste, heating and ventilation systems.
Installation of a High Efficiency Furnace
When installing a new high efficiency furnace there is additional venting required. There are different codes for different products and municipalities.
We install, repair, and maintain your HVAC Equipment.
can include locating and marking positions for connections, passages, and fixtures in walls and floors.
You want our HVAC experts to do the measuring, cutting, bending, and threading of pipes, testing pipes for leaks using air and water pressure gauges, be aware of all the legal regulations and safety issues, and ensure that safety standards and building regulations and permits are met.
In British Columbia a Furnace on its own is generally used to describe household heating systems based on a central furnace known also as either as a boiler or a heater. Replacement or repair service with gas fitting credentials. We can get you warmed up and ready for those colder days. A furnace filter should be replaced twice a year. This is not that hard to do but well worth it to make your furnace work more efficiently.
Installation of Ventilation Systems and Air Requirements
Are you building a basement suite? We can reposition your Furnace and Hot Water Tank and change layouts for basement suites. In Vancouver we have moved furnaces and changed the plenum to reposition the furnace, and put in an on demand system to increase even more space.
This can give you more square footage or help make that special area a different dimension.
GasFitter.ca follows the highest efficiency and environmental standards. This includes replacing at least 35% of the indoor air with outside air every hour, ensuring a healthy environment for our customers. With so many buildings in Canada being upgraded with energy star doors and windows, it is important to maintain an appropriate level of ventilation. In some homes, a high quality bathroom fan is sufficient. In other homes with forced air furnace systems, we install heat recovery systems to maintain efficiency—especially in colder environments. If building a new home in Canada it would be best to consult a GasFitter Associate to find out if an HRV (heat recovery ventilation system)is required. Regardless of your situation, we do our best to reduce your heatingand energy requirements and maintaining a healthy environment in your home.
Doing our best means keeping up to date with manufacturers requirements and standards on all HVAC equipment. Our GasFitter associates have a strong understanding of cooling and ventilation systems so that we can find the best solution for your home. It is vital for us to understand the basic properties of air and how to circulate it most effectively.
High efficiency gas furnaces circulate twice the volume of air as older, 70°- 90°F temperature-rise equipment. Also, with that same output, high efficiency heat pumps circulate three times more air than these older gas furnaces. However, it is also necessary to have an adequate duct system design or else your equipment will not operate at maximum efficiency.
Installations of HVAC Equipment
In the past, gas fitters installed forgiving, low cfm, high temperature rise, heating equipment. This worked fine when electricity was cheap and systems were inexpensive to operate. Today, however, efficiency is not only financially necessary but a part of being environmentally responsible. Now, the trend of air conditioning-ready furnaces with more powerful motors/blowers and induced draft fans has caused sound levels to rise. Furthermore, the reputation of forced air heatingbeing a quality choice has been suffering from poor installations and inefficient equipment choices.
HVAC and movement of Air Requirements
We know how to efficiently and quietly move high volumes of air by controlling duct velocity, airflow rate, duct aspect ratio and air pressure. We understand the power requirements of pushing and pulling air through duct systems. We understand the current fan laws and other useful tools used for sizing and installing duct systems to match the HVAC’s load requirements . We measure pressure and cfms and ensure we possess the exceptional skills to design free flowing duct systems customized for your home.
Heat load calculations for HVAC Installations and Load Requirements
It is of best practice to do a heat loss and heat gain calculation to your home when installing a new heating and cooling system for your home. When performing such a system to ensure comfort for you and durability for your equipment.
We understand the process of making informed equipment choices. In doing so we can create a comfortable and efficient environment in your home or building.
HVAC Installations and Load Calculations
We have to take into consideration not only the size of your home, but what is the layout of your home or building. The materials used in the construction process. How many windows you have, how big are your windows and which way do they face, north , south. The R value of your homes insulation, windows and doors. How many appliances you have. What kinds of ventilation your home has. The efficiency of you air seal, and the drafts within the building envelope. And the climate in which you live. And now we can properly size the equipment to maintain a balanced system to get optimum comfort and reliability.
3 Heating Load Calculation
The heat loss is divided into two groups:
(i) the heat transmission losses through the confining walls, floor, ceiling, glass, or other surfaces, and
(ii) the infiltration losses through cracks and openings, or heat required to warm outdoor air used for ventilation.
As a basis for design, the most unfavourable but economical combination of temperature and wind speed is chosen. The wind speed has great effect on high infiltration loss and on outside surface resistance in conduction heat transfer.
Normally, the heating load is estimated for winter design temperature usually occurring at night, therefore, internal heat gain is neglected except for theaters, assembly halls,
industrial plant and commercial buildings. Internal heat gain is the sensible and latent heat emitted within an internal space by the occupants, lighting, electric motors, electronic equipment, etc.
3.1 Heat Transmission Loss
Heat loss by conduction and convection heat transfer through any surface is given by:
(2) where Q = heat transfer through walls, roof, glass, etc.
A = surface areas
U = air-to-air heat transfer coefficient
Ti = indoor air temperature
To = outdoor air temperature
Heat transfer through basement walls and floors to the ground depends on:
(i) difference between room air temperature and ground temperature/outdoor air temperature,
(ii) materials of walls and floor of the basement, and
(iii) conductivity of the surrounding earth.
These portion of heat transmission is neglected in Hong Kong because of the fact that the weather in winter is not so severe and the values are very small in comparison with other forms of heat transmission.
3.2 Infiltration and Ventilation Loss
The heat loss due to infiltration and controlled natural ventilation is divided into sensible and latent losses.
3.2.1 Sensible Heat Loss, Qsb
The energy associated with having to raise the temperature of infiltrating or ventilating air up to indoor air temperature is the sensible heat loss which is estimated by:
(3) where r = air density
V = volumetric air flow rate Cpa = specific heat capacity of air at constant pressure
Ti = indoor air temperature To = outdoor air temperature
3.2.2 Latent Heat Loss, Qla
The energy quantity associated with net loss of moisture from the space is latent heat loss which is given by:
(4) where r = air density
V = volumetric air flow rate wi = humidity ratio of indoor air wo = humidity ratio of outdoor air hfg = latent heat of evaporation at indoor air temperature
The mechanical systems we are using today are more efficient and work under different principals than the equipment that we are replacing. It is not good enough to simply exchange equipment based on the BTU’s of your previous energy system. Your home has probably gone under some renovations, and upgraded the efficiency of your homes draft control units.
A high efficiency furnace with a rating of 97% burns around 50 gigajoules of energy a year to heat a typical home in BC. To compare, an old furnace with a rating of 60% would burn over 80 gigajoules a year to heat that same home. High-efficiency systems use around 25% less natural gas than standard systems. This mean you could be spending 25% more than you have to keeping your home warm with a dated system.
After January 31 2010 in BC we will not be allowed to install 80% mid efficiency furnaces unless in combination with a heat pump.
New furnaces use so much less gas than dated models because they lack a pilot light, (using hot-surface ignition) which uses up to 6% of you annual bill. As well this system closes off the chimney when the burners are off (prevents heat loss), and because they use heat exchangers with more surface area (creating more heat exchange). The stack temperature of your flue is 1200 degree’s, this energy is recovered. Unlike conventional forced air furnaces, condensing units capture most of the water vapour and heat contained in the hot flue gases that normally escape up the chimney. The escaping gases pass through a second heat exchanger providing that captured heat for your home as well, then the condensate is expelled at 70 degree’s
Being more efficient, newer systems minimize the amount of energy you consume and reduce your carbon footprint. But you must make sure a qualified professional calculates the size of system you require (heat load calculation). Having a system that is not the right fit for your home will result in excessive cycling and inefficiency.
High-efficiency furnaces also save energy by utilizing electronically commutated motors (ECM) to power the air circulation fan; ECMs consume less electricity than single speed motors and operate at better at low speeds, and start up with less of a draw.
A furnace’s fan motor is one of the largest consumers of electricity in the household. New units have variable speed DC motors, which cut the consumed electricity in half. If you run the fan continuously, a variable speed AC motor eats up just over $40 of electricity in a year; much less than the $185 of electricity consumption with standard motors. If the fan is only run while heating then it will consume around $30 a year; $55 with standard furnace motors.
High-efficiency furnaces prevent range hoods and exhaust fans from affecting the quality of the air inside your home. They draw in combustion air from outside of your home so that you don’t lose any of the heated air indoors. Natural gas, forced-air, systems deliver fresh, warm, air throughout your home. This is a major advantage compared to the electric baseboard heating systems, which do not ventilate the air at all.
