Boilers are an appliance that heats your home. Boilers operate by heating water to heat a space; the water is pumped through pipes into radiators or in-floor heating to heat a home. Additionally, specific “combi” boiler systems can also provide hot water for domestic use, such as showers or laundry.

The significant differences between high and low-pressure boilers are the amount of pressure pounds per square inch and per square inch produced by the boiler. Lower pressure boilers are typically lower maintenance, as they operate at a lower pressure. These boilers don’t require regular checks, only requiring a yearly inspection or when it begins breaking down.

High-pressure boilers heat steam to a higher temperature and pressure. Due to the higher pressures that it operates at, these appliances must be appropriately monitored. These need to be checked on an annual basis and when there are any issues. If a problem presents itself, it needs to be fixed immediately.

There are several different types of boilers available currently on the modern market. However, the most common type of boiler installed is known as a combi boiler. These boilers combine a water heater and central heating system into one appliance. What this means is that you don’t need an external water tank.

There are two other boilers available: a system boiler and a standard boiler. System boilers don’t require an external tank, but they only store hot water while the boiler carries out heating. Standard boilers require both hot and cold water tanks, and it’s generally recommended that they’re installed in older homes with existing heating and storage systems in place.
