Our 50kW boiler, covers the larger end of the domestic boiler market, and lets you expand into the light commercial boiler requirements that you may have. They are ErP “A” class condensing boiler with efficiency up to 108.8 % at 30C return, with key features such as a stainless-steel heat exchanger, fully modulating 10:1 range – which is perfect for heat loading matching ensuring a long and efficient product life cycle. They are low NOx emission boilers, class 6 – which means they have the least impact on the environment. Available in natural mains gas or LPG.

50kw System Boiler from Flexiheat UK – Gas Fired

A system boiler, has a separate unvented cylinder for producing and storing domestic hot water. This ensures that a consistent supply of hot water can be delivered to a large number of showers and taps simultaneously. As a result, a system boiler is an excellent choice for a property with multiple bathrooms.

System boilers do away with the requirement for a water tank in the loft since they get their water straight from the mains (which is required with a regular boiler). They then heat the water to provide warm water for the cylinder as well as central heating.

You have to install a heating expansion vessel on the installation (by others) to the make the boiler a full complete system boiler, which is usual at this output boiler.

System pressure for the hot water is mains water pressure and the stored water gives an excellent flow rate, which overcomes some of the problems with combi boilers.

Because combi boiler they are only really meant to sustain one hot water outlet at a time, they are not well suited to households with a high demand for domestic hot water. Heating performance may well be reduced in high-usage households because combi boilers routinely switch the burner from the heating system to hot water when there is a hot water demand.

A 50kw system boiler can be matched up to various sized cylinders to suit the home requirements for heating and hot water outputs.

However, should you flow requirement be under 20 Litres / minute, then you should look at our 50kW combi boiler webpage.

Modulation up to 1:10

For greater efficiency and reduced consumption both in heating and in domestic hot water production, when used with hot water cylinders

Low Class 6 NOx emissions-

NOx is a catch-all term for nitrogen oxides, which primarily include nitric oxide (NO) and nitrogen dioxide gas (NO2), our boilers have the lowest class emissions

System Pressure

Can operate on a heating circuit with a minimum pressure of 0.3 to 3 Bar maximum

Quality components

All boiler sub components are leading brand products and are selected through careful research for a guarantee of quality and reliability over time

Unrivalled quality / price ratio

The best boiler performance at affordable prices

A wall hung boiler, with modern upgraded controls, that make it one of the most efficient and also one of the quietest boilers manufactured on the UK and Irish markets – at only 52 Decibels – which makes a difference.

Heating output –

The boiler power will modulate the heat to the demand of the customers heating system installation, as the boilers output power range will go from from 50kw down to 5kW

Because the heat requirements of a boiler do not remain constant throughout the year owing to changing seasons, it may only be running at 20% of its capacity when it is warmer or at 80% when it is colder, our fully modulating 50kw gas boiler adapts to the heating system requirements, providing higher efficiency and reducing cost through wasted energy consumption.

Heating and Hot Water

Heating and hot water is provided by the boiler, via an indirect cylinder / calorifier – The heating side will heat your radiators or underfloor, whilst providing heat for the coil for the indirect cylinder

Controls

We do a range of controls that make your life easier, when it comes to controlling your boiler, from a basic room thermostat / programmer, with push control buttons all the way up to enhanced wireless internet controllers, such as nest,hive or bosch easycontrol thermostats, with features that provide you with the ability to regulate and control your heating from any extended location away from your home

Flue

We do a full range of flue options, such as horizontal or vertical kits, that ensure installation in the home easy – they are 80 mm / 125 mm outside diameter concentric – thus room sealed

Space required for installation

This 50kw heating boiler range is compact and modern, through award winning innovation in design and operation, it is also one of the quietest boilers to date on the UK and Irish markets -allowing you to locate the unit in any room and keep you cosy in the cold winter months.

Frequently asked questions

How many radiators can a 50kw boiler run?

The number of radiators a 50kW output boiler can run, will depend on the property. The average sized radiator in a new build home is 1.5kW output, thus newer properties the boiler can run 30 rads to be safe. With older less insulated properties, you’re looking at around 18 to 20 rads, click here for more details

Is a higher kW boiler better?

Boiler are sized to overcome the heat loss from the property ( normally at -5C outside, to give an internal temperature of 20C) in the previous years , you could oversize a boiler, which was not good for efficiency and your fuel bill, but these days the quality end of the market ensures that the boilers are modulating, which means they will operate down to some very low outputs – our 50kW gas boiler will operate down to 4.83kW flow rate, which ensures better heat load matching of the system, with high efficiency and lower running costs , click here for more details.

Delivery

We normally deliver the boilers on a small pallet service to prevent any damage, for a middle England postcode for example this is around £45, on a 2/3 day delivery date service. Other postcode areas such as the Scottish Highlands / Low Lands, or postcode areas for West Wales and Cornwall as more as it costs us more to send to these areas. For Isle of White, Channel Island, or Isle of man postcode areas, please consult us for more information on a carriage quote.

Gas safe registered engineer

As always, we insist that any gas boilers are installed by a gas safe engineer, not only for the interest of safety, but also for the fact that it’s a legal requirement for the gas installation to be done by a suitable qualified person, so you can sit comfortably, knowing you heating and hot water system is safe.See here for the gas safe website.
