Combi boilers are capable of providing hot water for your home and for the central heating system.

Because of the space-saving aspect, combi boilers are perfect for small homes that don’t have loft space.

The combi boiler range from Firebird has robust features with premium-grade steel and a heavy-duty plaster casing with a polyester-coated finish that protects the boiler from wear and tear and also cuts on heat loss.

This range of boilers is not only beneficial to the user but to the installer as well. They include features like easy access to commonly serviced parts, multi-directional flue options and simple wiring with the help of 7-pin plug.

You also get to enjoy the benefits that Firebird boilers are known for like reduced NOx emissions and an A-rated efficiency rating. They are perfect for users that are looking for greener boilers that are friendlier to the environment.

It has the same specifications to the indoor combi with the addition of a built-in frost thermostat that keeps it nice and warm when the temperature drops. You can install the boiler outdoors allowing you to free up much-needed space in your home while enjoying the luxury of a boiler.

Compare Firebird System boiler prices

Even with its trending and patented technology, Firebird system boilers follow in the footsteps of other system boilers. They don’t feature a bulky cold water tank in the loft. But, to keep up with the high demand for hot water, system boilers require a hot water cistern. It’s the only significant difference between a system and a combi boiler.

The hot water tank is safely kept inside an airing cupboard and stores hot water allowing the system to provide you with a constant supply of hot water on demand. Because of the tank, it’s possible to run to the bathroom simultaneously without any flow rate concerns.

Firebird has two types of system boilers. The first, Firebird’s Enviromax boiler range is ideal for indoor installation. It’s rich with features which include premium-grade steel construction with a minimum 4mm gauge.

Each of the models in this range also features a heavy-duty casing with a polyester-coat finish to protect the boiler from wear and tear.

The second range is the Enviromax System Pac which is a range of outdoor boilers. They have the same specifications as the indoor system boilers but have a built-in frost thermostat as an addition to allow them to function properly even in winter.

Both types of boilers come in four output models: 12 – 20kW, 20 – 26kW, 26 – 35Kw, 35 – 44kW.

Firebird Boiler Problems and Common Fault Codes

Once your Firebird boiler is up and running, you should keep an eye on some common problems and fault codes that may appear during the life of the boiler. As with other boilers, your boiler might run into some problems. Knowing what to do beforehand can save you vital minutes and even cut down on the cost of repairs and extent of damage.

Central heating not coming on

You might notice that water is available at the taps but, the central heating is not coming on. It’s best to check if the thermostats are on. You can also cautiously check if the bottom of the radiators are warm as well as the pressure of the boiler.

Suggested fix

The fix depends on the diagnosis. If the thermostats are not on, you need to turn them on. If the bottom of the radiators are cold, you need to bleed or vent them. If the boiler pressure is low, it could be a sign of a bigger problem. Have an engineer check for leaks before you try to top up and reset the boiler.

Low boiler pressure

This is a common problem that affects most boilers. It can be as a result of various factors each of which needs to be treated very seriously.

When the pressure of your Firebird boiler goes too low, the boiler will automatically cut out. You can check this by looking at the built-in pressure gauge. Anything below 1 bar is a red flag.

Suggested fix

If there are no other underlying issues, you can increase the boiler pressure yourself using the external filling loop. It’s a simple and safe procedure. If you’re unsure about anything, you should contact a registered Gas Safe engineer to assist you.

Boiler leaking

Just as a small leak can sink a big boat, a small leak can also destroy your boiler. There are many reasons there can be a leak in the boiler. The reasons range from faulty and worn out seals to corrosion caused by rust.

The leak can cause the electrical components to short circuit and if not repaired, it could damage the boiler. The first sign of leak is repeated loss of boiler pressure.

Suggested fix

If you’re lucky enough to spot the leak, turn off the water supply to prevent the leak from getting worse. Get in touch with a Gas Safe registered engineer to help spot the leak and fix it.

Sometimes, it’s difficult to spot the leak. But, if the boiler is losing pressure regularly, it should hint you that there’s a leak.

Radiators not heating up

A number of reasons can keep your radiators from heating up. The most common is sludge build-up inside the system. This is more so the case if the bottom of the radiators is not getting hot.

Suggested fix

If the build-up is not significant, bleeding the radiators can alleviate the problem. But, if it’s been a couple of years and you notice dirty water coming out of the radiators when bleeding, you need to have a power flush done to clear the system.
