Home Owner To do List-Tankless

Bosch vs Rinnai Tankless

When it comes to home improvement there are so many options available. Most homeowners make a mental to do list of the projects that are weekend projects and ones best left to the pros. To do lists are usually placed in order of cost and capability to complete the task. A tankless water heater is a project that is well worth putting at the top of your to do list. We can have REP come out and go over where a unit can be installed and what an install entails. Then you can spend the rest of your Saturday planning on how to use the extra space your old hot water tank took up.
With conventional tank type water heaters there is a strangely long list of things that are not exactly great selling points. Things like, pilot lights that miraculously go out at the most inconvenient times, limited storage capabilities, short life spans, and a loss of energy efficiency due to sludge build up at the bottom of the tank.
The tankless water heater solves a lot of the standard water heater problems. Current water heaters use energy by constantly working to maintain heated water temperatures of 40 to 50 gallons that is not even being used. A tankless system costs 60 percent less to operate than the standard tank because it only heats the water when it is requested by the home owner. Another selling point is the life expectancy of these units, double sometimes even triple to that of the traditional unit.
If you are trying to ‘Go Green’ most tankless water heaters are Energy Star approved. This means that you are not only reducing your carbon footprint by 63 percent compared to the standard unit, you will also be saving energy, and that means real money back in your pocket.
In addition to the money that you are going to be saving on reduced energy bills, the Provincial Government offers tax incentives of up to 30 percent for energy efficiency improvements.
Heating Water with a Tankless in Ontario

Buying a Tankless in Ontario |
So you’re thinking of getting a tankless water heater and you live in Ontario, that’s good these systems are excellent for the environment and your bottom line. Most…. Actually all of these systems are designed outside our country and thus outside our climate. You should take some extra precautions before purchasing a system.
If you take a look at the map you can extrapolate a rough estimate of ground water temperatures for Ontario. Sorry there doesn’t seem to be an accurate map of Ontario’s ground water values anywhere. I would use 35-37 Fahrenheit as a good starting point; your incoming water will never be much colder than that. The tankless water heater you choose will need to warm the water up from your starting temperature to your desired level. If the incoming water is 35 and you want hot water to be 110 your tankless needs to heat the water 75 degrees. This is quite a relatively significant increase and to produce this level of rise requires the water to pass through the heat exchangers at a slower rate.
In the summer Ontario ground water is often between 50 and 65 Fahrenheit, to reach your desired 110 degree level the water only needs to be heated 45 degrees. Sensors in the tankless measure incoming and outgoing temperature levels and adjust flow rates accordingly. Thus a system rated to provide 5 GPM (gallons per minute) with only a 40 degree temperature rise will likely only produce maybe 2 GPM in the winter when water temperatures are really low.
When you’re purchasing a new tankless for your home make sure you pay close attention to the tankless heaters specifications. Make sure that it is able to provide an adequate flow rate when your incoming water temperatures are at the lowest in the winter.
