A “combi” boiler system is an innovative combination of a high-efficiency water heater and a central heating boiler, all contained within one compact unit. This combination of components can eliminate the need for a separate hot water tank, which can result in cost savings for the home owner and also potential space savings within the property. This type of system is becoming increasingly popular due to its efficiency, compact nature, and cost savings. It is also relatively easy to install and maintain, making it a great option for many types of homes.
