Why Choose a Gas Combi Boiler

A Gas Combi Boiler is the normal installation nowadays in a small/medium sized property due to people wanting more space around the house (created by not needing Hot Water storage Cylinders or Cold Water storage tanks) and the need for Hot Water on Demand.

Gas Combi boilers work directly from the Cold Mains and supply Hot Water instantly without the need to use a Cylinder with an Immersion heater.

Gas Combi Boilers can be used for central heating by circulating hot water through radiators and Underfloor Heating systems.

How do Gas Combi Boilers Work

The water will pass through the boiler over a Heat Exchanger (made from Aluminium or Stainless Steel) which will produce Hot Water at the outlet almost immediately. Depending on Mains Pressure supply, gas combi boilers can achieve a Flow Rate ranging from 9.8 Litres per Min upto a massive 20 Litres per Minute.

Large Hot Water Demand for Gas Combi Boilers

In Small and medium sized properties, Combi boilers are an Ideal choice for due to minimal call for water i.e one Bathroom. Combi boilers will tend to struggle when calling for Hot Water from more than one outlet, which results in lower water flow as the hot water flow rate is divided by each water source used at the same time. Larger Gas Combi Boilers with a higher flow rate will cope better with these situations, but always consult your plumber first.

When fitting a Gas Combi Boiler to your Heating system, please note that you cannot boost the pressure to a shower by adding a Shower Pump as this is not allowed.
