Wynne’s Green Revolution – Hold On To Your Wallets

May 16, 2016

Today in The Globe and Mail, it was reported that the Wynne Liberals, intend to spend 7 BILLION DOLLARS of your money over 4 years to slash Ontario’s carbon footprint. How will they do this? Well, the article in today’s paper exposes the secret 57 page Climate Change Action Plan that the Wynne government intends to execute. It is a sweeping 80 policies grouped into 32 actions that will cost our province as a whole and all of us individuals huge money in the next 20 years.

I am really interested in hearing from all my friends how they feel about this initiative and how it will impact Ontarians. Please read the Globe article and let me know what you think.

I am very concerned about electricity becoming unaffordable for average consumers over this period of time. One main change the Wynne government intends to impose on Ontarians is outlawing any form of the affordable natural gas heat we now heavily rely upon and force consumers and businesses to heat their homes with electricity. Whether by forcing them into extremely expensive electric, heat pump or geo thermal heat pump based heating systems, our costs will skyrocket.

We were recently hit with a massive rate increase because we were using “too little” electricity and the poor electricity generation monopolies complained of insufficient profit because of their reduced sales that were directly impacted by the installation of so many high efficiency systems across Ontario.

Now Wynne has the ideal plan to ensure that the electricity monopolies get the profits they want. By forcing every home and business to heat with electricity, the demand for electricity will skyrocket, and of course the rates will skyrocket as well, but the consumer will be severely battered on all levels. Firstly, the cap and trade tax which will raise the price of everything, then our heating systems will change to electricity which will drastically increase our heating costs and to make it even worse, our electricity rates will skyrocket.

I am very concerned that living in Ontario will become unaffordable for the average working class family. How many of us can afford to increase our budgets by 30%? I believe conservatively that this will be the cost of these revolutionary changes.

But as a heating and air conditioning contractor who is also an Accredited Geothermal Designer and Installer, I must thank the Wynne liberals for ensuring that every heating and air conditioning system in Ontario will require changing to very costly new systems in short order. This will definitely keep us contractors very busy and very profitable.

Beware of Drive By Pricing

December 23, 2010

Hello Friends,
Whenever I am asked to provide pricing for a replacement furnace or air conditioner, we always perform a full analysis of the home including a heat loss/gain report to ensure that our customer gets the best system for their needs. This procedure requires a 2.5 hour visit to the customer’s home. Recently, a customer asked me, “Why do you need so much time? Another contractor gave me a price in 5 minutes! Don’t you know what you are doing?”

I would like to answer this question.

The replacement of your home heating and air conditioning system is a significant investment that will dictate your comfort, efficiency and safety for the next 10 – 20 years. Only with the proper research can you be confident that your system will meet your expectations and satisfy your needs.

Some of the many questions that need to be answered are as follows.

  1. Is your home warm enough?
  2. Does your current system maintain a uniform temperature throughout your home?
  3. Are there rooms that are always too cold or too warm?
  4. Is the air in your home fresh or do you find that your home air is stale and stuffy?
  5. Is your home too dry? Is your furniture and/or hardwood floors cracking?
  6. Is your home too humid? Do you have a mould or condensation problem?
  7. Will the new air system be compatible with the existing duct system and piping system in my home?
  8. Do you have enough hot water?
  9. How will this new system affect my air quality?
  10. How will this new system affect the pressure in your home?
  11. Is your home air clean? Does anyone in your household have breathing issues like asthma and allergies?
  12. Is your existing system oversized and operating inefficiently?
  13. How much heat do you actually need?
  14. How much cooling do you actually need?

As you can see, there are so many issues that must be dealt with in order to make the right equipment selection and to ensure that your selection will work well together with your existing infrastructure.

I have been to so many homes where the client is suffering because the contractor they hired to replace their furnace just offered a quick 5 minute Drive By Quote and failed to properly assess the home and their needs.

Any contractor who makes a proposal with a 5 minute visit will not be able to propose the best system for your budget, comfort, safety and efficiency.

The CMHC Canada Mortgage and Housing Corporation has published a FREE guide on how to buy a new furnace, boiler and/or air conditioner. You can click here to get to the order page and you can order the printed booklet or electronic copy.

For your interest, I have put a copy of the guide below.

Boilers Part 18 – Final Conclusions

December 2, 2010

Hi Again,

This article is the final in this series of how to select a replacement boiler. The conclusion is that it makes sense to invest in a Direct Vent Condensing Boiler. Make sure that your contractor knows which boilers have low pressure drop throught the heat exchanger and which boilers do not require an annual heat exchanger flush. If they do not have these answers, they have not done their homework and you should not buy from them. If you would like to know brands and models of boilers that have the right features for you, please just comment on this blog and I will answer you. You can also call me at my office at 416-781-1054 ext. 23. or email me at joe@premi-air.ca.

Boilers Part 17 – Restrictive Heat Exchanger = High Pumping Costs

November 30, 2010

The second disadvantage of most Direct Vent Condensing Boilers is their restrictive heat exchangers. Not all DVCB have this disadvantage however so you must make sure to ask your contractor about this. Let’s say that you have a 3,000 square foot home with an 80,000 BTUH boiler. You would probably need about 8-10 GPM or 8-10 gallons of water passing through your boiler per minute. Most boilers would have a pressure drop through your boiler of 8 feet of head. The best boilers have a pressure drop as low as 5 feet of head. This means that with the right boiler your pump will work half as hard. Pumping water around your house uses quite a bit of electricity. With a non restrictive heat exchanger, you will be able to keep this cost to a minimum.

Make sure that your contractor understands pump and boiler flow curves so that your system will be designed to run as efficiently as possible.

Boilers Part 16 – High Efficiency Boiler Disadvantages

November 28, 2010

The Direct Vent Condensing Boiler is the best choice for any home. However, you must be careful when selecting the right boiler for you.

In order to successfully transfer the heat from the flame to the water as easily as possible, the vast majority of condensing boilers force the water through a very restrictive heat exchanger with many small passages. This can cause 2 very serious problems.

The first problem is that if one of these passages becomes blocked with debris or dirt from the system, the heat exchanger will quickly overheat and fail. A heat exchanger replacement on a high efficiency boiler can be in excess of $2,000. It would be a shame to lose all your fuel savings on a major repair like this. These restrictive heat exchangers require extensive cleaning annually. Since many people neglect to call for service, and many contractors don’t even know about this required cleaning, many people have suffered disappointment and heat exchanger failure. Life doesn’t have to be this complicated. If this boiler is installed with the proper flow design, dirt and air separator and cleaned as per the manufacturers’ instructions, it will last a long time.

In my next post, I will discuss the second problem with these restrictive heat exchangers.

Boilers Part 15 – Turndown

November 25, 2010

Hi Again, Turndown is the ability of a boiler to reduce its input to match the load. Imagine a home with 3 floors and a separate thermostat and heating zone for each floor. When all three floors require heat, the demand might be 80,000 BTUH. This would require an 80,000 BTUH boiler. If only the basement needed heat, the load might only be 20,000 BTUH. Firing an 80,000 BTUH boiler would be overkill and horribly inefficient. All DVCB have a turndown that allows the boiler to fire at the required rate for that time so the boiler would fire just at the 20,000BTUH that you need. Efficiency is enhanced once again.

Now that it is crystal clear that the best option for a boiler is the DVCB, Direct Vent Condensing Boiler, I would like to discuss the problems with these boilers and how to avoid them.

Boilers Part 14 – Low Water Temperature Operation

November 23, 2010

Hi Again,

Today I’d like to discuss the advantage of low temperature operation and how it enhances your energy savings. We have discussed in previous posts that most of the time, your radiators will give you enough heat with water temperatures between 90 Deg. F. and 120 Deg. F. If you have in floor radiant heat, your water only needs to be around 90 degrees all the time. In order to extract the most heat from your gas flame and get really high efficiencies, the water entering the boiler must be as low as possible. 90 Deg. F. water will suck so much more heat out of the flame than 140 Deg. F. water. The problem with most boilers is that such low water temperatures will shock the boiler and cause it to crack and leak. Complete destruction!! The DVCB is designed for low water temperature conditions. As a matter of fact, it works best with low water temperatures since it is able to condense and extract so much more heat from your gas dollars. This compounds your savings.

Boilers Part 13 – The Heating Cycle With Outdoor Reset

November 21, 2010

Today I will illustrate the heating cycle with outdoor reset.

Your thermostat is set for 70 deg. F. The temperature drops to 69 degrees and the boiler fires up. Based on the outside temperature of 50 degrees, your boiler reset controller determines that a water temperature of 100 degrees will provide the right amount of heat. The boiler starts heating your water until it reaches 100 degrees. Your home heats up to 70 degrees and the boiler shuts off, but the temperature doesn’t go up higher because your radiators are only 100 degrees. In order to maintain 70 degrees in your home, tha radiators must stay at 100 degrees so they will never cool down. Rather, they will stay at 100 degrees and maintain your exact set point of 70 degrees in your home. How efficient, How comfortable? As it gets colder outside, your boiler will automatically adjust the water in your system hotter and hotter to meet your exact heating needs. Imagine how comfortable it will feel in your home without temperature fluctuations? Imagine how quiet your system will be without the constant noise of your pipes expanding and contracting as they heat up and cool down. But most of all, imagine how much energy you will save due to this operating efficiency.

See this video to learn more about outdoor reset.

Boilers Part 12 – The Heating Cycle

November 18, 2010

Let’s say you have a typical 3,000 square foot home with cast iron baseboard or radiators. This is what happens in a typical heating cycle.
Your thermostat is set at 70 Degrees Fahrenheit. The temperature in your home drops to 69 Deg. F. and your thermostat sends a signal to your boiler to fire. Your entire piping and radiator system is at room temperature or 69 Deg. F. Keep in mind that the weight of all your piping and radiators is around 5,000 lbs. Your boiler fires and starts warming the water, all the steel piping and cast iron radiators to 140 Deg. F. This will take around 20 minutes to achieve since there is 5,000 lbs to heat up. While your house waits for heat, the temperature continues to drop. By the time tha radiators warm up enough to start warming your home, the temperature probably has dropped to 65 Deg. F.
Now your 5,000 lbs of steel and cast iron has reached 140 degrees and the temperature has reached setpoint at 70 degrees. The boiler shuts off but the 5,000 lbs of steel in your home is still radiating het and the temperature in your home continues to rise. By the time your heat peaks and the radiators cool down and stop emitting heat, your home is probably 75 degrees.
Now your house starts to cool and the cycle starts all over again.
What is happening is that yu are getting a very wide range on 10 degrees in your home. This will not be comfortable and as you het your home to 75, you are wasting loads of energy.

In my next post I will illustrate the heating cycle with a DVCB (Direct Vent Condensing Boiler) that is equipped with Outdoor Reset.
