What is a combi boiler?
22 Dec : Updated 24 Dec ● 1 min readCombi boiler, or Combination boilers, are the most popular type of boiler in the UK. They’re used by 74% of households.
They’re named ‘Combination’ because they combine a high-efficiency water heater and a central heating boiler all in one package.
Combi boilers are efficient and cost less in heating bills.
That’s because:
- They only heat water when you need it, rather than storing hot water.
- They’re small and compact, as they don’t use an external hot water tank.
