New Furnace Installation Peterborough
Regulations and requirements are making Heating Contractor
s and furnace manufacturers
to comply with more stringent minimum energy performance standards for residential gas furnaces
, imported or shipped from State to State or for sale or lease in North America and to implement a reporting requirement for electricity consumption of the furnace fan
blower motor and standby power. Because of their increased efficiency, a new
uses, on average, up to 33 to 38 percent less electrical energy than old models.
A New Furnace and the ROI
there has never been a better time to make an energy upgrade with your new high efficiency furnace
. Take advantage of Government Grants.
Furnace manufacturers around the world have been making the very best out of almost all the energy that goes into it.
Efficiency ratings are measured from how much energy goes into the furnace
and how much is used. And with the second heat exchanger on new
high efficiency furnaces
the energy is scrubbed of its heat before the exhaust stage. In most cases the heat from the flue in most cases that was the chimney. We now use a plastic pipe for exhaust in many instances because the heat coming out is now much less. Eliminating the chimney (in Peterborough
is where most roof leaks are as well it is good for getting rid off a major source of heat loss in your home and better for creating an air tight home). This is in fact the source for the advances in efficiency. As it brings in fresh air into a sealed system to exhaust out a sealed system. No longer taking warm air from the inside the house to help slow down the flue to gain it’s temperature control. Measuring the energy going in and the energy being used and the energy leaving the structure not being used is the way to think about AFUE.
Governments and New Furnace Installation
Regulatory bodies proposes to increase the minimum performance level, Annual Fuel Utilization Efficiency (AFUE), for gas-fired furnaces
with an input rate not exceeding 65.92 kW (225 000 Btu/h) to 90%. This is certain to rise in the future, to 95% or 98%. Are Heat Pump
Systems to be an added with any new furnace installation
in the future to the regulations when replacing your heating
equipment on in the future?
With more than 14.6 million homes using gas furnaces
, the impact of improving their efficiency has major benefits to all in terms of energy conservation; operational cost savings; improved air quality; and, reduced our carbon foot print.
The warmer climate since a colder climate will increase the run time and lower the number of cycles. For this reason a new high efficiency furnace
should run very efficiently in the Peterborough
are. The number of cycles is much more harmful than run time, given that gas burners are clean and efficient. Various studies substantiate a 20 year furnace
average lifetime before replacement. And with Peterborough
temperature the cost savings will start to insure after about 6-7 years.
Gas furnace electricity consumption
A standard furnace
fan motor is sometimes called a permanent split-capacitor (PSC) motor. When used in continuous operation all year long, for either heating
or cooling, this motor will consume more electricity than an average refrigerator. Depending on the efficiency of the motor, energy use can go as high as 800 kWh/yr. Overall, energy consumption can be reduced using higher-efficiency options.
High Efficiency Furnaces
deliver greater energy savings and providing a more stable heat by using a variable-speed, direct current Electronically Commutating Motor (better known as an ECM motor) to run the air circulation fan. In homes where the fan is run continuously or for extended periods, such a motor can significantly reduce electricity bill and could save between $50 and $150 a year. Consider this type of motor for your furnace, Heat Recovery Ventilator
(HRV)or heat pump.
In addition to energy savings, these types of motors have long maintenance-free continuous operation. Less heat is generated in the rotor, allowing the bearings to run cooler. When an ECM motor starts it has about a third the amount of draw on the amperage than a traditional PSC motor. This reduces motor noise and increases bearing/motor life expectancy. Variable speed motors create less heat, compared with traditional PSC motors, and therefore can reduce the summer cooling load in air-conditioned homes in Coquitlam.
What you expect from your New Furnace
EMERGENCY FURNACE SERVICE FROM YOUR INSTALLER– 24/7means action –
Who ever you go forward with for your new furnace
installation make sure you will be able to get a hold of them 24 hours a day. A trusted company you know will come back even after the furnace installation
. Today’s furnaces
are very reliable as well as improved efficiency but little things can happen. Make sure the company you go with to replace your furnace can get there with a good response time. North America can get really cold at times, water in your pipes can make them burst under such conditions with no heat in a home during freezing conditions.
Your new furnace guarantee off install
GasFitter is committed to helping you by improving the energy efficiency of your home including you heating system. A new furnace
can be installed in the same location as the old inefficient furnace
. Trained Gas Fitter technicians can install a new plenum to the same ductwork and then into the rest of the ventilation system that carries the warm air and return air throughout the house.. We train our staff in the very latest installation techniques and keeping up with the ever changing codes and building requirements. The new HVAC
technologies are changing very fast. Keeping our Gas Contractors
informed about the new products that are coming out is important to know you are getting the very best from the new high efficiency furnace
and from the people installing them. You will lower your energy bills. In fact, we will SAVE YOU A MINIMUM OF 20% ON YOUR HEATING
during the first year. a homeowner with an old gas furnace
could save about $300 a year by switching to a condensing gas furnace
with an AFUE of 96 percent.
SUBSTANTIAL GOVERNMENT REBATES AVAILABLE TODAY ON A NEW FURNACE OR AIR CONDITIONER
With your new high-efficiency furnace
, the installation company should also quote you with programmable thermostat. In many instances there will need to be a wire upgrade to make the furnace
perform better anyway. But it will allow you to preset household temperatures for specific times of the day and night when you are either sleeping or not at home at all. Some of the new thermostats will actually tell you if something is wrong and to phone the technician. As a general rule, you can save 2 percent on your heating bill for every 1°C you turn down the thermostat.
Heat loss Calculations
Before making your purchasing decision, ask a certified heating contractor to determine the right size of furnace
for your home. And to do a Heat Loss Heat Gain Calculation to ensure the right fit for your new furnace to your home size and R value. taking into account recent technology developments, the heat loss and heat gain characteristics of your house, and other factors. And you will enjoy your new furnace
and the cost savings for years to come.
Calculating fuel costs
Here is a rough comparison of the relative costs of heating an older house in Peterborough
. You can put in your own fuel prices and the efficiencies of the appliance that you are choosing to compare relative costs.
Note: It is often difficult to isolate the cost per unit of fuel, be it gas or electricity. Include all the costs that relate to the m³ of consumption for gas (for example, gas supply charge, gas delivery charges, gas surcharges). Electric utilities often also have a bewildering range of charges. Apply all the charges except fixed charges (for example, $10/month connection charge).
For oil appliances, use an energy content of 38.2 MJ/litre of oil. For electricity, use 3.6 MJ/kWh and 100-per-cent efficiency.
Note: 80 GJ (or 80 gigajoules) is the energy required for heating the example house over the winter (heat load). Your own house will likely be different. However, the relative costs calculated for alternative fuels and furnaces
in the example house should help you make a selection for your house.

Calculating house heat
loss from utility bills
Here is a sample calculation, using a three-month meter reading for a typical house. You can use any period (but at least two weeks of winter weather is necessary). You can either read the meter yourself for the information, look at your furnace
bills or phone your utility to see if they have appropriate records. The natural gas usage of other gas-fired appliances
in the house is estimated from gas utility data and subtracted from the total for the period in question, so that the gas requirement for heating can be isolated. (Oil furnaces
are harder to size using this method, but it may be possible using oil fill-up intervals and the number of litres delivered.)
The goal is to find a relationship between the gas consumed and the heating degree days (HDD). A heating
degree day is essentially the number of degrees of heating required over the course of 24 hours, compared to a reference temperature of 81F.
Use the data from the “Degree Days: Below 81F” row.
Once the relationship of the HDD and gas consumption is established, then you can calculate gas consumption for the design temperature in your area. Calculating the size of the furnace
necessary on the coldest day of the year will mean that the furnace
has the capacity to handle any expected local temperature. You can find a furnace’s efficiency
rating on its EnerGuide label or in the product documentation.
Total gas consumption from December to March = 1,320 m3
Estimated consumption for other gas appliances (data from utility) = 306 m3
Therefore, gas consumption during the period for heating = 1,320 - 306 = 1,014 m3
Heating degree days for that period = 2,840 HDD
Heating consumption by degree day = 1,014 m3/ 2,840 HDD = 0.3570 m3/HDD
Heating consumption at 53 HDD/day = (53 HDD/day)(0.3570 m3/HDD) = 18.9 m3/day
Where gas has an energy content of 37.5 MJ/m3, and the existing furnace
has an efficiency of 72 per cent, then:
Heat loss at 53 HDD/day = (18.9 m3/day) (37.5 MJ/m3)(0.72) = 510 MJ/day or 21.3 MJ/h
According to the energy content of electricity, 3.6 MJ/h = 1 kW, then 21.3 MJ/h = 5.9 kW
This heat loss would require a furnace
that produces an output of 5.9 kW or about 20,100 Btu/h (1 kW is approximately 3,412 Btu/h).
If we allow the CAN/CSA F280 permissible over sizing of 40 per cent, then the proper furnace sizing
would be (1.4)(20,100 Btu/h) = approximately 28,100 Btu/h.
If you are calculating for an oil furnace
, heating oil has an energy content of 38.2 MJ/litreNan
