What is a Tankless Water Heater?
Dec 5th
Tankless Water Heaters, also called Instantaneous, Demand Water Heaters or insant hots, provide hot water only as it is needed. Traditional storage water heaters produce standby energy losses that cost you money.
No one leaves their car running overnight so that its warm in the morning. A Tankless Water Heater is used only when there is a demand for hot water.
Tankless Water Heaters heat water directly without the use of a storage tank, thus they are able to avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. In a gas-fired Tankless Water Heater a gas burner heats the water. As a result, Tankless Water Heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water, nor do you have to worry about it running out. Typically, gas-fired Tankless Water Heaters will produce higher flow rates than electric Tankless Water Heaters. Some smaller Tankless Water Heaters, however, cannot supply enough hot water for simultaneous, multiple uses in large households. For example, having 2 people taking simultaneous showers and running the dishwasher at the same time can stretch a Tankless Water Heater to its limit. To overcome this problem, you simply need to purchase a system that is correctly sized for your home. To get a free evaluation and quote fill out this form HERE
Green $avers – Energy Audit
Dec 4th
Green$aver’s is an NRCan-licensed energy advising company that can conduct a thorough energy assessment and use the assessment to identify cost-effective energy efficient recommendations to implement, including draft-proofing and insulation. Green$aver can also be responsible for implementing the measures in each home with their experienced retrofit crews.
As with all audit companies Green$aver’s is an NRCan-licensed company that can show you how to improve the comfort of your home and cut heating and cooling costs, while ensuring adequate ventilation for a healthier indoor environment.
Using a Government developed software (Hot 2000) Green Savers (and all Auditing companies in ontario) are able to provide a detailed on-site assessment of your home’s energy use. This audit comprises the entire house from the attic to the basement. Once all the measurements are recorded and entered into Hot-2000 a detailed report is given to the customer. This includes a checklist of recommended retrofits to improve the energy efficiency of your home and, in some cases, to reduce your water consumption. The report will also show the ecoENERGY grant amount for each eligible upgrade you can receive by carrying out these energy saving improvements.

Tankless Sizing – Total GPM
Dec 4th
Buying a tankless system can be a tricky task as there is a number of different units on the market today. In addition you need to take into account numerous different factors to determine the correct sizing and venting.
You will first want to figure out what the total GPM that you need supplied at your house, do this to calculate the total.
If your showerhead is relatively new, the gallons-per-minute consumption rating is inscribed somewhere on the outside of the fixture. If it’s not, do this quick test.
Hold a 1-gallon container under a faucet or fixture and time how many seconds it takes to fill the container with the faucet opened all the way. Then divide 60 by the number of seconds it took to fill the container. For example, a fixture that filled the container in 30 seconds would be rated at 2 gpm.
While you’re at it, it’s a good idea to clean any screens in the fixtures of any scale deposit.
The maximum gpm rating your water heater needs depends on how many fixtures and appliances will be drawing hot water at the same time. Add up the gpm of your fixtures and then check off the fixtures and appliances that will be in use simultaneously. This should provide you with the Total Gallons per Minute that a tankless will need to provide.
Now the last thing to consider is your location, if you are in the southern US the incoming water supply will be much warmer than in the dead of winter in southern Ontario. This plays a significant factor as the tankless unit needs to heat the water almost twice the amount, inturn reducing the output. A tankless rated at 6.8 gpm may only be able to produce 4.8 when it has to heat the water from 38 Fahrenheit instead of 64.

Paloma Tankless Systems
Dec 3rd
The Paloma tankless water heating system can be a good choice for large homes that are using more 
than one water source at the same time. These systems also have the added benefit of using either propane or natural gas, depending on which model you choose. However the Paloma Tankless system is a rather large unit that doesn’t come with a lot of bells and whistles as far as controls are concerned. Overall it is a good system, but there are other options that are slightly better. The Paloma’s warranty is still one of the best in the business at ten years on the heat exchanger and three years on all other parts.
These systems are manufactured outside of north america, so if you are looking to buy a little more local look at the Rinnai Tankless systems, which is built in the USA.
Tankless Opperational Differences
Dec 2nd
Tankless vs. Tanks: What Are The Differences?
Tanks and Tankless units have operational differences you need to be aware of.
Typically, you can expect to use approximately 70% of a tank’s volume; i.e., a 50-gallon tank should provide approximately 35 gallons of hot water. The burner initiates to reheat the tank, but the latter can only recover at approximately 1 GPM. Thus, the recovery wait begins. This stored volume, in combination with the standing pilot light, usually results in an Energy Factor (EF) in the low range of 0.53 ~ 0.62 for gas fired, tank-type water heaters. “Energy factor is what the end user pays for. A water heater with an energy factor of 0.62 means that for every dollar spent heating water, $0.62 is being used to heat the water. The remaining $0.38 is wasted.”
Whatever the maximum flow rate for any Tankless unit that flow is continuous for as long as there is demand. And unlike a tank-type heater, the temperature remains constant at the selected set point. There is no stored water and no pilot light, so Tankless systems have a high EF range between 0.81 and 0.94, depending on the model and gas type.
