Pool Review
  • How do I know if I have a boiler in my house?
    You may have a boiler if you see the following heat source systems in your house: Cast iron radiator or baseboard heater is usually found in old houses in downtown areas. Air handler systems are usually found in condo townhouses in the mechanical room. They are a forced air heating and cooling system with a low-profile duct system, which can be a little noisy. In-floor heating systems are usually found in basements to heat the floor slab. They are commonly installed in custom houses and renovated basements, often as part of underpinning projects, as well as in driveway snow melting systems.
  • What is a combi boiler?
    The combi boiler is usually a wall-mounted boiler that provides domestic hot water and heat for heating applications like in-floor heating or an air handler system. It's popular in condo townhouses as it saves space and does not need an additional water heater system. The following are the common brands for combi boilers. Baxi Boiler, Navien Boiler, Glow brand Boiler, Bosch Boiler, Rinnai Boiler
  • What is a high-efficiency boiler?
    Residential high-efficiency boilers, also known as condensing boilers. When natural gas is burned in a boiler, it produces carbon dioxide and water vapour as by-products. In a standard non-condensing boiler, the water vapour and carbon dioxide are wasted energy. In contrast, a condensing boiler captures this wasted energy, converting the vapour back into the water to extract additional heating energy.
  • What are the best boiler brands in Ontario Canada?
    Rinnai, Navien, and Viessmann are reputable brands known for producing high-quality condensing boilers with durable stainless steel heat exchangers and long lifespans. These boilers are low-maintenance, and replacement parts are readily available. Additionally, they provide reliable customer service and warranty coverage.
  • What is the average cost of installing a new boiler?
    The average cost of a boiler or combi boiler typically ranges from $3,000 to $5,000, depending on various factors such as size, brand, features, and efficiency. When it comes to installation, the cost varies based on factors such as heating application, piping material and labour, accessories, pump or zoning controllers, and gas flow vent piping. Generally, replacing a boiler on a working existing system can start from $1,500 to $3,000, and it typically costs less than installing a completely new system. You can easily get an equipment and installation estimate from 4Most Energy by scheduling an on-site or virtual appointment. The quickest way to get in touch with us is by giving us a call, sending a text message, or reaching out via WhatsApp video call or text. You can also fill out the contact form with more details about your project.
  • Why a gas-licensed contractor must install your gas pool heater?
    New gas piping installation or modifications, including underground and outdoor piping, must meet all-natural gas or propane code requirements. This involves using the correct materials, conducting leak tests, and ensuring proper flue gas to prevent hazards and combustion issues. 4most Energy brings over a decade of expertise in pool heater repair and replacement, serving both the HVAC and pool industries. Customers can count on competitive pricing, expert services, and a satisfaction guarantee.
  • What water type of heat pumps are used in condos?
    Heat pumps are an efficient and effective way to regulate indoor temperature in both residential and commercial settings. However, there are differences between the two types of heat pumps - air-source heat pumps and water-source heat pumps. While residential air-source heat pumps require two separate systems, one indoor and one outdoor (condenser), commercial water-source heat pumps are more commonly used as package units without the need for an outdoor condenser. Instead, water-source heat pumps use the building water loop system to extract and dissipate heat during refrigeration cycles, unlike air-source heat pumps that rely on the outdoor unit to perform this function. This makes water-source heat pumps a great option for commercial buildings like condos, where space may be limited and ductless systems are preferred.
  • What is the cost of installing a water source heat pump in a commercial unit in Ontario, Canada?
    The cost of installing or replacing a commercial heat pump can vary between $5000 to $8000, depending on the heat pump's situation. Additional factors such as limited access to the ceiling, removing the existing unit, ceiling height, unit relocation, extra ductwork, a challenging drain system, or a faulty isolation valve can increase the labor cost. If you want an accurate estimate, you can reach out to us and speak with our commercial HVAC specialist. We provide a free consultation over the phone or at the job site to ensure the best services are delivered.
  • Does Daikin provide a wide range of replacement options for Commercial units?
    Daikin l Water Source Heat Pumps are an ideal solution for residential high-rise condominiums and light commercial HVAC applications. Daikin Heat Pump Systems are known for their efficiency and low-cost operation. They come in two different configurations: horizontal and vertical. Additionally, they are the most reliable replacement options currently available in the market. Daikin offers a 1-year part and labor warranty, as well as up to a 5-year compressor warranty.

  • How much does installing a Condo Heat Pump in Ontario, Canada, cost?
    The average cost for a condo heat pump chassis ranges from $2800 to $5800, depending on the replacement chassis required. In some cases, finding a compatible chassis for older heat pumps may be challenging. To obtain an accurate estimate, you can send us a picture of the existing unit along with the model number, and we will provide a quick estimate.
  • When is the time to replace the pool heater?
    The average lifespan of a pool heater is 10 to 12 years. A cracked heat exchanger, which can result in water leaks, ignition failure, and incomplete combustion, is a clear indication that a replacement may be needed. You can always contact us for a free consultation or a second opinion to determine if your pool heater is still repairable or needs to be replaced.
  • Why a gas-licensed contractor must install your gas pool heater?

  • What are the common reasons that can damage your pool heater and reduce its lifespan?
    Improper Winterizing: It's important to properly winterize pool heater sensors and the heat exchanger to prevent damage from ice forming in the system during the winter. If not done correctly, your pool heater may not work when you reopen your pool, even if it was functioning properly last season. Lake of maintenance: It's important to remember that cleaning the heater before the start of the season can significantly improve its efficiency and ensure smooth operation. Accumulated dirt can lead to issues such as incomplete combustion, faulty safety switches, overheating, and problems with electronic parts. Improper installation: Installing the pool heater downstream of any water disinfection system that could introduce chlorine or other chemicals into the pool heater can accelerate heat exchanger corrosion.
  • Can I control the pool heater or pool pump with a smart Wi-Fi switch?
    Smart switches for the pool heater and pump allow you to connect to your Wi-Fi and control them using your phone or any smart home system, such as Alexa, Google Home, Apple Home, and Samsung Home. By scheduling the pool heater, you can maintain the pool water temperature at a comfortable level throughout the season, while a smart pool pump switch can save energy and keep the water crystal clear. We recommend checking your utility's peak timing and scheduling your smart timer accordingly. Usually, in summer, the off-peak time is from 7 pm to 7 am. 4Most Energy supplies and installs a range of pool heaters, pool pumps, WI-FI Controllers, and Smart Switches.
