Combi boilers are ideal for smaller homes with limited space because they remove the need for any additional hot or cold water storage tanks as you would need for a regular or system boiler. They are also great for those who have a demand for instant hot water, this is because combi boilers are supplied with cold water directly from the mains, this water is then heated and distributed to your taps and radiators when needed.
The Potterton 30kW has an output of 30kW for central heating, which is powerful enough to heat a larger home with up to 20 radiators and 1-2 bathrooms. However, many smaller homes would not require this kW output, and therefore the Potterton Assure 25kW may be better suited to those properties. However, the Assure combi boiler range also has a 36kW boiler available for properties with higher demand.
