The Combi Boiler effectively combines the central heating (CH) with the domestic hot water (DHW) into one single ‘combined’ system within your home – hence the term ‘combi’.

In essence, Combi’s are continuous water heaters, providing both modern conveniences of ‘On-demand’ hot water and central heating for your home and family.

The Combi only operates when the room temperature as detected by the connected thermostat, falls below the desired temperature. With older, less efficient boiler types, the pilot light is continuously on (as indicated by the visible flame). However, a Combi’s pilot light is only ignited when central heating or hot water is required. Only when the Combi’s thermostat detects a fall below the desired room temperature or hot water is drawn from a sanitary appliance does the pilot light ignite. This saves energy usage and therefore energy costs.

To homeowners, water flow-rates to a central heating and hot water system may be meaningless bytes of data, however these rates determine how quickly hot water is powered to the shower on winter’s morning. Now you wouldn’t want to be shivering under a cold shower would you?

The Flow-rate performance of a Combi Boiler is measured and therefore rated by its DHW flow-rate. For guidance, the kW ratings and associated approximate flow-rates for a domestic Combi Boiler are typically 24 kW to 54 kW and 9 to 23 ltrs/minute – respectively.

Space – The Combi Frontier

It is worth noting that high flow-rate models can simultaneously supply more than one shower, which can be a very desirable facility for homes with several bathrooms. For larger homes, the installation of a Combi Boiler to each floor level will provide the homeowner with the benefits of efficiencies in separate hot water supplies together with separate temperature controls. Moreover, one of the combis can also act as a back-up should maintenance or repair work be required to the other unit.

Space savings can be made with the installation of a new Combi Boiler, as there are no requirements for a space consuming water tank and its associated pipework. Furthermore, a new Combi Boiler reduces the installation time together with costly materials and labour.

With a new Combi installation, roof spaces and lofts are free of fixed, bulky water tanks and labyrinths of pipework, presenting the opportunity to create more desirable living space in the form of designer loft conversions.

A recent Case Study carried out by Combi Boiler revealed that a new Combi Boiler installation converted into a new, cool habitable living space, which resulted into a very pleasing, higher property value.

If you add this capital gain to the year-on-year money savings achieved due to the energy efficiency of a new Combi, then your quids in! Possibly several thousand quids in!!

Combi Boiler

The Combi Boiler (also known as an instantaneous boiler) is the No. 1 choice for UK homeowners. Its popularity is born out of its efficiency of directly heating the incoming mains cold water supply to the sanitary fittings within your home. Convenience and bliss!

Instantaneous Condensing Boiler

A higher efficient version of the Combi Boiler is the Instantaneous Condensing Boiler, which as the name states operates as an ‘instantaneous’ boiler. The upshot being, less energy usage for the same desirable hot water and comfort heating.

Combi (Storage) Boiler

A variation to the Instantaneous Combi Boiler type is the Combi (Storage) Boiler, which is designed to provide a higher performance due to the internal storage of heated water. The water storage facility generally provides higher initial water supply from cold water mains when first turning the tap on the sanitary appliance. Once the stored heated water has been completely drawn and depleted, the boiler will effectively operate as an ‘Instantaneous’ Combi Boiler.

Efficiencies will be dependent on the boiler make and model and water storage capacity.

Combi (Storage Condensing) Boiler

This type effectively operates as the ‘storage’ boiler type with at higher efficiencies for the homeowner.

Combined Primary Storage Unit (CPSU)

This special type of storage Combi Boiler has a very large water storage facility, allowing for high water flow rates to sanitary fittings and draw-off points. Furthermore, flow rates to radiators is higher and achieved before the water storage is fully utilised.
In essence, Combi Boiler means hot water on-demand from a space saving installation.

However, the Combi benefits don’t stop there! A Combi Boiler only heats the water you require at any given time, therefore saving you precious energy and hard earned money on your energy bills.

The Combi Boiler has proven to be almost everyone’s cup-of-tea and here’s why;

1. Combi boiler based central heating installations are generally simpler, quicker and therefore cheaper! Click here to find out more >
2. A combi boiler system doesn’t require a cold water tank (usually located in the loft with traditional central heating systems), therefore saving valuable storage space while economising on the installation process.
3. A combi boiler draws its cold water feed directly from the mains supply so you get efficient mains water pressure.
4. A combi boiler system produces hot water on-demand by heating water drawn directly from the cold mains supply.
5. You and your family can therefore enjoy the benefits of an efficient power shower without the need for an additional pump.

Biasi Riva Advanced HE 24S Combi Boiler

The Combi Boiler combines a high energy efficient water heater and central heating boiler into one single (space saving) unit and has proven to be the most popular type of boiler in the UK, accounting for over 50% of new boiler purchases.

Space – The Combi Fontier

The compact size and combined engineering provides much greater flexibility when choosing the Combi Boiler’s installation position in your home. So rather than the boiler’s position being restricted due to the location of the associated water storage cylinder (typical of inefficient conventional boilers), an energy efficient Combi Boiler is free to place itself in far more convenient locations, such as a corner kitchen wall or within a fitted cupboard – upstairs or downstairs.

The Combi Boiler frees-up valuable living space for you and your family.

Combi Makes Your Bills Smaller (..bills I said!)

After having the pleasure of an energy efficient Combi Boiler installed, your energy bills may start to appear different. They may start getting a little smaller! Don’t worry, this is quite normal.

With an A-rated Combi Boiler hot water is efficiently provided on-demand and at mains pressure from within the actual unit, rather than having to wait (whole episodes of Corrie) for a large storage cylinder to heat up inefficiently. The installation of a Combi Boiler is also typically quicker and cheaper compared to conventional boiler systems.

Therefore, you save money on installation costs and energy bills all while getting hot water and heating on demand. A win-win situation, which is quite normal for Combi Boiler!
