What's a Combi Boiler Calgary?

Combi boilers are one of the most common boilers. It can provide hot water and also be the central heating system of your home. As the name shows, a combi or combination boiler was initially designed to merge all central heating system components into a single unit.

Traditional boilers heat water in the boiler’s cylinder and send it to the hot water storage tank. However, in combi boilers, the water isn’t stored. It draws cold water from the main tank and heats it as required. Then it sends that water wherever it is required. That can be your kitchen tap, shower, or the central heating system pipes in your home or office.

If you feel your demand for hot water is higher than average, you can also opt for small hot water storage so that you are not left hanging in the bathroom with soap all over you. 

How Does it Work?

Combi boilers use gas in some countries to power up if the domestic properties are connected to gas. It can also use LPG or oil as fuel. There are also electric combi boilers as LPG and oil can be fussy to deal with since you’d have to refill them. 

So when it comes to operation, combi boilers have two independent heat exchangers. One connects to your central heating system and the other to your hot water supply. There is a sensor in the combi boiler, which signals the heat exchanger when you request hot water. The heat exchanger causes the boiler to burn the fuel to heat the water that passes over it. 

There are valves in the combi boiler that work in different directions to one another, which means that you can send hot water to your central heating system or a tap in your home. Usually, you’ll have a control system to set the temperature you like.

Frequently Asked Questions

Manufacturers have improved the look and design of boilers, but still, many people prefer tucking their boiler away from sight. If you are wondering where to place your combi boiler, the following are a few suggestions that we’d like you to consider:

  • Bathroom
  • Kitchen
  • Utility room
  • Garage
  • Loft 
  • Or airing cupboard

You must consider the costs that are associated with it, though. Moving a boiler is not something anyone can do. You’ll need professional help, like, Alpha Plumbing.

Large homes will have multiple bathrooms and a kitchen, so there will be many outlets for hot water. Unfortunately, combi boilers supply hot water to only one tap at a time. For larger families, a systematic boiler will be more appropriate. 

Although it highly depends on what model of combi boiler you have purchased and how often you service it, they can last anywhere between 10-15 years. 

When the interface of your boiler and the thermostat tells you that the central heating is off but still feels hot, it is not off. You may have to get it checked by a professional, especially if you don’t know anything about the system. But the most common reason for this problem is a faulty check or diverter valve. 

The valves may have collected debris and need a simple cleaning, or they may be broken and need replacing.
