A conventional boiler installation in a home will contain a tank for cold water storage and a cylinder for hot water. This setup has a rather large footprint, but it works well for large buildings or households that consume a lot of hot water, particularly at the same time. A combination boiler, also known as a combi boiler, is another option to consider.
This type of boiler heats your house similar to a regular boiler, but instead of storing hot water for you to use through your home’s faucets and appliances, it heats water on demand only when you need it. Because the storage tanks have been removed, these boilers take significantly less room. Combi boilers are comparable to tankless water heaters, which we will examine later. The key is that they also heat your home because they are boilers too.
Combination boilers, commonly known as Combi boilers, provide high efficiency space heating and domestic hot water (DHW) in a compact design that is simple to install and maintain. When a hot water faucet is turned on, the incoming water passes through the heat exchanger. Heating the water to the required temperature is prioritized by heated boiler water provided by the fire tube heat exchanger. When it is necessary to heat the area, a diverter valve transfers the hot boiler water into the external space heating loop.
What is the difference between a combination boiler and a conventional boiler?
Although both can heat your home and supply hot water, there are significant variations. Traditional gas boilers are primarily used for space heating. To warm the air, hot water from the boiler is pumped through radiators or a hydronic heating system. Traditional boiler water may also be utilized for household hot water by passing it through a separate, integrated water heating unit before being routed to a fixture like a faucet or a shower. Some traditional boilers may be used with potable water, while others require further water treatment.
A combination boiler is designed to provide both space and water heating from a single unit. A combi boiler, like a tankless water heater, delivers hot water on demand. To provide the greatest possible experience, it can also effortlessly switch between water heating and space heating. You may consider replacing your old storage tank water heater and condensing boiler with these units. An air source heat pump can also be a great supplement to your overall heating system.
Is it true that a combi boiler saves money?
Combi boilers are very energy efficient for both space and water heating, and they may help to reduce your home’s energy costs. They maintain high efficiency even when heating demands are decreased.
