Quick Combi Boiler wiki

Combination or combi boilers are a boiler unit that combines the feature of central heating and a tankless domestic water heater in a single container. Thus a combi boiler serves dual purposes, both as. a domestic water heater and at the same time as a central water heating system heat exchanger. The fuel that is used in the boiler is usually oil or gas, giving rise to 2 classes of combi boilers, Oil combi boilers and gas combi boilers. Some combination boilers have small internal water storage vessels. These boilers are rated by the DHW flow rate. The kW ratings for domestic usage are 24 kW to 54 kW.

For these power ratings, Comb boilers have flow rates of 9 to 23 liters per minute. There are also larger commercial units available. The cost of installing a combi boiler is significantly low. Combis occupies very less space, as water tanks and associated pipes and controls are not required. A single combi unit can be used to heat different zones in the same residence. A good example of this is supplying both the downstairs heating system and the upstairs heating system. Sometimes people use 2 separate combi boilers for backup purposes, in case one combi boiler goes down. Notably Combi boilers are hugely popular in Europe and as such, places like the UK and Scotland have seen rise in demand for such products as combi boiler insurance and central heating cover.
