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.

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 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 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.
